leading publishers who market to technology advertisers.
 
   
    The   Company   focuses  on   providing  renewable   subscription-based  and
proprietary products as well  as one-time research services.  In 1995, 84.7%  of
the  Company's total revenues were generated from the sale of renewable products
and services.  Due  to  the  strategic  value  of  IntelliQuest's  products  and
services,  its innovative use  of proprietary technology  to collect and analyze
information and the  Company's reputation  for excellent  customer service,  the
Company averaged dollar-weighted renewals for subscription-based products of 84%
over  the three year period  from 1993 through 1995.  Eight of the Company's ten
largest customers in 1994 were also among its ten largest customers in 1995.
    
 
    The Company has made substantial  investments in proprietary technology  for
survey  administration, data  collection and  data analysis.  IntelliQuest was a
pioneer in the use of disk-based  interactive survey techniques, which are  used
to gather information from technology purchasers and users. The Company has made
a  substantial investment in  ReplyDisk, its proprietary  survey software, which
allows the  Company  to  easily create  customized  interactive,  graphical  and
multi-media  survey  applications.  The  Company  has  also  used  the ReplyDisk
platform to create  off-the-shelf survey software  applications. The Company  is
currently  developing  NetQuest,  which  will allow  the  Company  to administer
interactive surveys on the Internet.

    While the Company incurred net losses in each of 1993 and 1994, it  recorded
a  net profit  in 1995 and  has improved  operating margins over  the past three
years by leveraging fixed annual investments in subscription-based products over
an increasing subscriber base. The Company has also invested in data  collection
technologies  and  panel recruitment  to  further lower  cost  of revenues  as a
percentage of  total  sales.  In  1995, the  Company's  operating  income  as  a
percentage of revenues increased to 6.0%, based on revenues of $19.1 million and
operating  income of $1.1 million, compared to an operating loss as a percentage
of revenues of 5.0% in 1992, based on $3.9 million in revenues and an  operating
loss of $196,000.
 
    The  Company's  growth  strategy  is  to  (i)  leverage  its  expertise  and
reputation to  expand  its  presence  among other  business  units  of  existing
customers  and to  capture a  portion of  the growth  in such  customers' market
research budgets; (ii) extend its product and service offering to new  customers
within  both the Company's current target markets and new target markets such as
data communications, on-line  services and interactive  new media; (iii)  expand
its  recently introduced Internet-based research  tools and information services
such as Web site surveys  and a survey to  measure Internet and on-line  service
usage  among technology  purchase influencers;  (iv) expand  marketing services,
such as database  marketing, associated with  electronic customer  registration;
(v)  expand international  market research capabilities  to meet  the demand for
consistent  worldwide  market  research;  and  (vi)  pursue  strategic  business
acquisitions  of companies that provide products  or services not offered by the
Company, have  strategic  customer  relationships,  are  located  in  attractive
geographic locations or have proprietary technologies.
 
RECENT DEVELOPMENTS
 
    In  May  1996,  the  Company  acquired  IntelliQuest  Communications,  which
resulted in IntelliQuest  Communications becoming a  wholly-owned subsidiary  of
the  Company. IntelliQuest  Communications is  a leading  provider of electronic
customer registration and marketing  services for a  number of leading  computer
hardware,  software  and peripheral  companies. IntelliQuest  Communications has
developed a  proprietary frame  relay network  that allows  electronic  customer
registration  from  over  90  countries  and 400  cities  worldwide  as  well as
registration via Internet Web sites.  The Company's acquisition of  IntelliQuest
Communications enables the Company to expand its offering of electronic customer
registration products.
 
    In  connection with  the acquisition, the  Company issued  562,500 shares of
Common Stock in exchange for all of  the outstanding shares of common stock  and
outstanding options and warrants of IntelliQuest Communications. The acquisition
was  accounted for  as a  pooling of  interests and,  accordingly, all financial
information in  this  Prospectus  has  been  restated  to  give  effect  to  the
acquisition.  See "Management's  Discussion and Analysis  of Financial Condition
and Results of Operations" and  the consolidated financial statements and  notes

    IN  ADDITION  TO THE  OTHER INFORMATION  IN  THIS PROSPECTUS,  THE FOLLOWING
FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE SHARES
OF  COMMON  STOCK  OFFERED  HEREBY.  THIS  PROSPECTUS  CONTAINS  FORWARD-LOOKING
STATEMENTS   WHICH  INVOLVE   RISKS  AND   UNCERTAINTIES.  SUCH  FORWARD-LOOKING
STATEMENTS INCLUDE, BUT ARE NOT LIMITED TO, THE COMPANY'S EXPECTATIONS REGARDING
ITS FUTURE  FINANCIAL  CONDITION  AND OPERATING  RESULTS,  PRODUCT  DEVELOPMENT,
BUSINESS AND GROWTH STRATEGY, MARKET CONDITIONS AND COMPETITIVE ENVIRONMENT. THE
COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE
FORWARD-LOOKING  STATEMENTS AS A RESULT OF  CERTAIN FACTORS, INCLUDING THOSE SET
FORTH IN THE FOLLOWING RISK FACTORS AND ELSEWHERE IN THIS PROSPECTUS.
 
   
    RELIANCE ON KEY CUSTOMERS; TECHNOLOGY  INDUSTRY CONSOLIDATION.  The  Company
has  relied  on  a limited  number  of key  customers  for the  majority  of its
revenues. The Company's 10  largest customers in 1994  and 1995 generated  63.7%
and  60.5%, respectively, of the Company's revenues in each of those periods. In
1995, the Company's two largest customers, Microsoft and IBM, each accounted for
10% or  more of  the Company's  revenues  and together  accounted for  25.6%  of
revenues. The Company expects that these two customers will each account for 10%
or  more  of  revenues in  1996  as  well. Substantially  all  of  the Company's
subscriptions and customer contracts are renewable annually at the option of the
Company's customers,  although no  obligation  to renew  exists and  a  customer
generally  has no minimum purchase commitments thereunder. In addition, there is
significant consolidation of  companies in the  technology industries served  by
the  Company, a  trend which the  Company believes  will continue. Consolidation
among the  Company's top  customers could  adversely affect  aggregate  customer
budgets for the Company's products and services. No assurances can be given that
the  Company will maintain its existing customer base or that it will be able to
attract new customers. The loss of one or more of the Company's large  customers
or  a significant reduction  in business from such  customers, regardless of the
reason, would have a  material adverse effect on  the Company. See "Business  --
Customers" and "-- Sales and Marketing."
    
 
   
    DEPENDENCE  ON SUBSCRIPTION  AND CONTRACT RENEWALS.   In 1995,  84.7% of the
Company's revenues were  derived from subscriptions  to the Company's  renewable
subscription-based  products and  contracts for  renewable proprietary products.
The Company expects that a material portion of its revenues for the  foreseeable
future  will  continue  to be  derived  from such  subscriptions  and contracts.
Substantially all  such  subscriptions  and  customer  contracts  are  renewable
annually  at the  option of the  Company's customers, although  no obligation to
renew exists  and  a customer  generally  has no  minimum  purchase  commitments
thereunder.  To the extent that customers fail  to renew or defer their renewals
from the quarter anticipated by the Company, the Company's quarterly results may
be materially adversely affected.  The Company's ability  to secure renewals  is
dependent   upon,  among  other  things,  its  ability  to  deliver  consistent,
high-quality and timely  data. In  addition, the marketing  and market  research
activities  of the Company's customers are dependent  on the timing of their new
product  introductions,  size  of  marketing  budgets,  operating   performance,
industry  and economic conditions  and changes in management  or ownership. As a
result of such factors, there can be no assurance that the Company will be  able
to maintain its historically high renewal rates. Any material decline in renewal
rates  from such levels  would have a  material adverse effect  on the Company's
operating results.  See  "Management's  Discussion  and  Analysis  of  Financial
Condition and Results of Operations" and "Business -- Sales and Marketing."
    
 
   
    FLUCTUATIONS  IN OPERATING  RESULTS; SEASONALITY.   The  Company's operating
results in any  particular fiscal period  have fluctuated in  the past and  will
likely   fluctuate  significantly  in   the  future  due   to  various  factors.
Substantially all revenues and expenses  attributable to the Company's  Computer
Industry  Media Study ("CIMS") product for a particular year are recognized when
the final study is usually completed and delivered, usually in the third quarter
of that  year. Delay  in delivering  the final  study in  any given  year  could
postpone  recognition of such revenues and  expenses until the fourth quarter of
such year, which would  materially affect operating results  for such third  and
fourth  quarters. Furthermore, all costs related to CIMS are included in cost of
revenues and  none are  allocated to  sales, general  and administrative  costs,
which tends to reduce the Company's third
    
 
                                       6
<PAGE>
quarter  gross  margin  below that  of  other  quarters. Many  of  the Company's
customers operate in industry segments  that are becoming increasingly  seasonal
as technology vendors have increased their focus on consumer markets, with sales
in  the fourth  calendar quarter  constituting a  growing portion  of the annual
sales of  such  customers. This  may  translate  into seasonal  demand  for  the
Company's   products,  particularly  the   customer  registration  products.  In
addition, the Company's operating results may fluctuate as a result of a variety
of other factors, including  the timing of orders  from customers, the size  and
timing  of orders for customer registration products, response rates on customer
registration products, delays in development  and customer acceptance of  custom
software  applications, product  or panel  development expenses,  new product or
service introductions or announcements by the Company or its competitors, levels
of market acceptance for new products  and services, the hiring and training  of
additional  staff and  customer demand for  market research, as  well as general
economic conditions. Because a significant portion of the Company's overhead  is
fixed in the short term and because spending commitments must be made in advance
of  revenue commitments by customers, the Company's results of operations may be
materially adversely affected in any  particular quarter if revenues fall  below
the  Company's expectations. These factors, among others, make it likely that in
some  future  quarter  the  Company's   operating  results  may  be  below   the
expectations  of securities analysts and investors,  which would have a material
adverse effect on the market price of the Company's Common Stock. The  Company's
operating  results for the third quarter of 1996 are not yet available and there
can be no assurance that these results will meet the expectations of  securities
analysts.  Any failure  to do  so could  have a  material adverse  effect on the
market price of  the Company's  Common Stock. See  "Management's Discussion  and
Analysis of Financial Condition and Results of Operations."
 
   
    COMPETITION.   Overall,  the technology-focused market  research industry is
highly  competitive.  The  Company  has  traditionally  competed  directly  with
relatively  small,  local  providers of  survey-based  technology-focused market
research. The  Company also  competes  directly with  third party  providers  of
customer  registration software  (such as  KAO Infosystems  Company) as  well as
vendors' own customer registration software.  In addition, the Company  competes
indirectly  with significant providers  of (i) analyst-based, technology-focused
market research (such  as Gartner Group,  Inc., META Group,  Inc. and  Forrester
Research,  Inc.);  (ii)  survey-based,  general market  research  (such  as A.C.
Nielsen Company,  NFO Research,  Inc., Information  Resources Inc.  and The  NPD
Group,  Inc.); and  (iii) analyst-based,  general business  consulting. Although
only  a  few   of  these   competitors  have  to   date  offered   survey-based,
technology-focused  market research  that competes  directly with  the Company's
products and  services, many  of these  competitors have  substantially  greater
financial,  information gathering and  marketing resources than  the Company and
could decide to  increase their  resource commitments to  the Company's  market.
Moreover,  each  of  these  companies  currently  competes  indirectly,  if  not
directly, for  funds available  within aggregate  industry-wide market  research
budgets.  There are  few barriers  to entry into  the Company's  market, and the
Company expects increased competition in  one or more market segments  addressed
by  the Company,  which could adversely  affect the  Company's operating results
through pricing pressure, required increased marketing expenditures and loss  of
market  share, among other factors.  There can be no  assurance that the Company
will continue to compete successfully  against existing or new competitors.  See
"Business -- Competition."
    
 
    RAPID  TECHNOLOGICAL  CHANGE AND  NEW PRODUCT  INTRODUCTION.   The Company's
customers compete  in markets  characterized by  rapid, continual  technological
change. The Company's success will depend in part upon its ability to anticipate
and  keep pace  with rapidly  changing technology  and to  add new  products and
services which  address the  increasingly  sophisticated, rapidly  changing  and
demanding  needs  of  its customers  and  their evolving  market  strategies. In
particular, the  Company  is  expending significant  resources  to  develop  its
proprietary  customer registration products to  take advantage of certain market
opportunities. However,  such software  products may  contain defects  following
customization  or when new  versions are released;  the Company has  in the past
discovered software defects in certain of its products and may experience delays
or lost  revenue  to  correct such  defects  in  the future.  In  addition,  the
significant  growth in the use of the World  Wide Web (the "Web") portion of the
Internet has  created the  opportunity to  use the  Internet as  an  information
transmission medium. Accordingly,
 
                                       7
<PAGE>
the  Company  is  expending  significant  resources  to  develop  Internet-based
information collection  tools. There  can  be no  assurance, however,  that  the
Company will be successful in developing and marketing, on a timely basis, these
or other new or improved products and services that adequately and competitively
address  the  needs  of the  marketplace.  Any  failure to  continue  to provide
insightful and timely data in a manner that meets rapidly changing market  needs
could  materially and adversely  affect the Company's  future operating results.
See "Business  --  Products  and  Services"  and  "--  Product  Development  and
Technology."
 
    DATA  COLLECTION  RISKS.   The Company  currently collects  information both
telephonically and electronically.  In addition,  certain of  the Company's  new
products  and services  involve the  use of  the Internet  and commercial online
services to  gather  information from  end  users  for processing  and  sale  to
customers of the Company. A number of legislative initiatives exist domestically
and abroad that seek to regulate the telephonic or electronic collection of data
about  persons.  In addition,  an  increasing number  of  court cases  have been
brought seeking damages  and injunctive relief  for actions allegedly  violating
so-called  "rights of privacy."  The law in  this area, both  statutory and case
law, is highly unsettled. No assurance can be given, therefore, that the Company
will be allowed  to continue  to pursue existing  or proposed  new products  and
services.  In addition,  the Company's  ability to  provide timely  and accurate
market research  to  its customers  depends  on  its ability  to  collect  large
quantities  of  high quality  data  through interviews,  customer registrations,
product satisfaction questionnaires and certain other surveys. If receptivity to
the Company's customer registration, interview and survey methods by respondents
declines, or for  some other  reason their  willingness to  complete and  return
surveys, registrations, or other information declines, or if the Company for any
reason cannot rely on the integrity of the data it receives, it would reduce the
quantity  and/or quality of the data the  Company seeks to disseminate and would
have a material adverse effect on the  Company's ability to market and sell  its
market  research products  and on  its results  of operations.  See "Business --
Products and Services."
 
   
    RISKS RELATED  TO CIMS.   CIMS  is one  of the  leading databases  of  media
readership  and  viewership habits  of  both business  and  household technology
purchase influencers in  the United  States. Because many  advertisers use  CIMS
data  as a key component in their  media buying decisions and because many media
companies use CIMS data to promote their media properties, such data can have  a
significant  impact on advertiser demand for,  and advertising rates charged by,
such media  properties. In  the  past, media  companies have  occasionally  been
highly  dissatisfied with the results of the surveys or the manner in which such
results have been used by  their competitors. Furthermore, the Company  recently
revised  data from a study that was inaccurate due to software defects, which it
remedied and  disclosed  to its  customers.  Although none  of  these  potential
disputes or inaccuracies in CIMS has resulted in litigation against the Company,
there  can be no assurance that the Company will not face future litigation as a
result of media company dissatisfaction with CIMS or the results thereof.
    
 
    MANAGEMENT OF GROWTH; POSSIBLE ACQUISITIONS.  Since inception, the Company's
growth  has   placed   significant   demands  on   the   Company's   management,
administrative,  operational  and financial  resources. In  order to  manage its
growth, the  Company  will  need  to  continue  to  implement  and  improve  its
operational,  financial  and  management  information  systems  and  continue to
expand, motivate and effectively manage an evolving and expanding workforce.  If
the   Company's  management   is  unable   to  effectively   manage  under  such
circumstances, the quality of the Company's products, its ability to retain  key
personnel  and its results of operations could be materially adversely affected.
Furthermore, there can be no assurance that the Company's business will continue
to expand. The  Company's growth could  be adversely affected  by reductions  in
customers'  spending  on  market  research  or  customer  registration products,
increased competition,  possible pricing  pressures and  other general  economic
trends.   Although   market  research   expenditures  by   technology  companies
 
                                       8
<PAGE>
have increased in recent years as such companies have adopted certain  marketing
strategies  traditionally utilized by consumer goods manufacturers, there can be
no assurance that  this trend will  continue or that  technology companies  will
continue  to  rely  on  externally-generated  market  research  to  enhance  the
marketing of their products.
 
    The Company hopes to achieve a portion of its future revenue growth, if any,
through acquisitions  of  complementary businesses,  products  or  technologies,
although  the Company currently has no commitments or agreements with respect to
any  such  acquisition.  As  part   of  this  strategy,  the  Company   acquired
IntelliQuest Communications, Inc. ("IntelliQuest Communications," formerly known
as  Pipeline Communications,  Inc.) in  May 1996.  The Company's  management has
limited experience dealing with  the issues of  product, systems, personnel  and
business  strategy integration  posed by acquisitions,  and no  assurance can be
given that the integration of the IntelliQuest Communications acquisition or any
possible future acquisitions will be  managed without a material adverse  effect
on  the business of the Company. In addition, there can be no assurance that any
possible future acquisition will  not dilute the  Company's earnings per  share.
See  "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Growth Strategy."
 
    DEPENDENCE ON KEY PERSONNEL.   The Company's future performance will  depend
to a significant extent upon the efforts and abilities of key personnel who have
expertise  in developing, interpreting and  selling survey-based information for
technology markets. Although customer relationships  are managed at many  levels
in  the Company, the loss of one or more of IntelliQuest's corporate officers or
senior managers could  have an  adverse effect  on the  Company's business.  The
Company's  success may  also depend  on its  ability to  hire, train  and retain
skilled personnel  in  all areas  of  its business.  Competition  for  qualified
personnel  in the Company's industry is intense,  and many of the companies with
which the Company  competes for qualified  personnel have substantially  greater
financial  and other  resources than  the Company.  Furthermore, competition for
qualified personnel can be expected to become more intense as competition in the
Company's industry increases. There can be no assurance that the Company will be
able to recruit, retain and motivate a sufficient number of qualified  personnel
to compete successfully.
 
   
    EXPANSION  OF DIRECT  SALES FORCE.   The Company has  historically relied on
customer referrals,  supplemented by  its own  sales and  marketing efforts,  to
generate  the majority of its  revenue growth. Although the  Company has a small
number of dedicated account representatives, it only recently began to develop a
formal sales  management structure.  As the  Company develops  new products  and
services  targeted at broader-based  market segments, it  intends to continue to
expand its sales force. The Company's plans for future growth may depend in part
on, among other things, its unproven ability to hire, train, deploy, manage  and
retain  an increasingly large direct sales force. There can be no assurance that
the Company will be able to develop or manage such a sales force. See  "Business
- -- Sales and Marketing."
    
 
    HISTORY  OF NET LOSSES;  UNCERTAIN PROFITABILITY.   The Company incurred net
losses in each  year from 1991  through 1994  before recording a  net profit  in
1995.  As  of December  31,  1995, the  Company  had an  accumulated  deficit of
approximately $3.2 million. In  view of the  Company's prior operating  history,
there   can  be  no  assurance  that  the  Company  will  be  able  to  maintain
profitability on a quarterly or annual basis or that it will be able to  sustain
or  increase its revenue growth in  future periods. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
    LIMITED PROTECTION OF  PROPRIETARY SYSTEMS,  SOFTWARE AND  PROCEDURES.   The
Company's success is in part dependent upon its proprietary software technology,
research  methods, data analysis techniques, and internal systems and procedures
that it  has  developed  specifically  to  serve  customers  in  the  technology
industry.  The Company has no patents;  consequently, it relies on a combination
of copyright,  trademark and  trade secret  laws and  employee and  third  party
non-disclosure  agreements  to  protect its  proprietary  systems,  software and
procedures. There can be  no assurance that  the steps taken  by the Company  to
protect  its proprietary rights will be  adequate to prevent misappropriation of
 
                                       9
<PAGE>
such rights or that  third parties will  not independently develop  functionally
equivalent  or superior  systems, software  or procedures.  The Company believes
that its systems, software  and procedures and other  proprietary rights do  not
infringe  upon  the  proprietary  rights  of  third  parties.  There  can  be no
assurance, however,  that  third parties  will  not assert  infringement  claims
against  the Company in the future or that  any such claims will not require the
Company to  enter into  materially  adverse license  arrangements or  result  in
protracted  and costly litigation, regardless of  the merits of such claims. See
"Business -- Intellectual Property and Other Proprietary Rights."
 
    RISKS ASSOCIATED WITH  INTERNATIONAL OPERATIONS.   Revenues attributable  to
international  market research represented 21.0% and 26.0%, respectively, of the
Company's revenues for  1994 and 1995.  The Company expects  that revenues  from
international market research will continue to account for a significant portion
of  its  revenues and  intends to  continue to  expand its  international market
research  efforts.  However,   the  Company's   international  data   collection
operations  are  subject to  numerous inherent  challenges and  risks, including
maintenance of  an international  data collection  network that  adheres to  the
Company's  quality standards, fluctuations in  exchange rates, foreign political
and economic  conditions,  tariffs and  other  trade barriers,  longer  accounts
receivable  collection  cycles  and  potentially  adverse  tax  consequences. In
addition, demand for the Company's international market research depends on  the
international  sales  and operations  of its  customers,  which may  increase or
decrease over time. The addition of  market research coverage in new  geographic
territories can be expected to require the commitment of considerable management
and  financial  resources  and  may negatively  impact  the  Company's near-term
results of operations. Any material decline in the Company's ability to  provide
and  market timely,  high-quality data  that is  consistent across international
markets would  have  a material  adverse  effect  on the  Company's  results  of
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
    CONTROL  BY  MANAGEMENT.   Holders of  shares  of Common  Stock do  not have
cumulative voting  rights,  and therefore  the  holders  of a  majority  of  the
outstanding shares of Common Stock are able to elect all of the directors of the
Company. Upon the closing of this offering, the Company's executive officers and
directors,  together with entities  affiliated with them,  will beneficially own
approximately  21.0%  (17.2%  if  the  Underwriters'  over-allotment  option  is
exercised  in full) of  the outstanding Common Stock,  including options held by
them that are exercisable within 60 days of August 31, 1996. As a result,  these
stockholders  will  be  able  to  exercise  significant  influence  over matters
requiring stockholder  approval, including  the election  of directors  and  the
approval   of  significant   corporate  matters   such  as   change  of  control
transactions. The  effects of  such influence  could be  to delay  or prevent  a
change  of  control  of  the  Company unless  the  terms  are  approved  by such
stockholders. See "Management" and "Principal and Selling Stockholders."
 
    UNSPECIFIED USE  OF PROCEEDS.   The  principal purpose  of the  offering  of
shares  by the Company is to increase  the Company's equity capital. The Company
will  not  receive  any  proceeds  from  the  sale  of  shares  by  the  Selling
Stockholders.  The Company  expects to use  the net proceeds  from this offering
primarily for working  capital and  general corporate purposes.  In addition,  a
portion  of  the  proceeds may  be  used  for the  acquisition  of complementary
businesses, products or technologies, which  the Company evaluates from time  to
time.  The Company has no  current specific plan for  any significant portion of
the proceeds of this offering. As  a consequence, the Company's management  will
have  discretion over the use of all of the proceeds for the foreseeable future.
See "Use of Proceeds."
 
    EFFECT OF ANTI-TAKEOVER PROVISIONS.   The Company's  Board of Directors  has
the  authority  to  issue up  to  1,000,000  shares of  Preferred  Stock  and to
determine the price,  rights, conversion ratios,  preferences and privileges  of
those  shares without any further vote  or action by the Company's stockholders.
The rights  of the  holders of  Common  Stock will  be subject  to, and  may  be
adversely  affected by, the rights, including economic rights, of the holders of
any shares of Preferred Stock. Any such issuance, while providing flexibility in
connection with possible acquisitions and  other corporate purposes, could  have
the  effect of making it more difficult for  a third party to acquire a majority
of the outstanding  voting stock  of the  Company. Furthermore,  the Company  is
subject  to the anti-takeover provisions of  Section 203 of the Delaware General
Corporation Law that prohibit the Company from
 
                                       10
<PAGE>
engaging in  a "business  combination" with  an "interested  stockholder" for  a
period  of three  years after the  date of  the transaction in  which the person
first becomes an  "interested stockholder," unless  the business combination  is
approved  in a  prescribed manner.  The application  of Section  203 and certain
other provisions of the Certificate of Incorporation could also have the  effect
of  delaying  or preventing  a change  of  control of  the Company,  which could
adversely  affect  the  market  price   of  the  Company's  Common  Stock.   See
"Description  of Capital  Stock --  Anti-Takeover Effects  of Provisions  of the
Certificate of Incorporation, Bylaws and Delaware Law."
 
   
    SHARES  ELIGIBLE  FOR  FUTURE  SALES;  REGISTRATION  RIGHTS.    Sales  of  a
substantial number of shares of Common Stock in the public market following this
offering could adversely affect the market price for the Company's Common Stock.
The  number of shares of Common Stock available for sale in the public market is
limited by  restrictions under  the  Securities Act  of  1933, as  amended  (the
"Securities  Act")  and  lock-up agreements  entered  into by  the  Company, its
executive officers and directors  and all Selling  Stockholders under which  the
holders  of such shares and  options to purchase such  shares have agreed not to
sell or otherwise dispose of any of their  shares or options for a period of  90
days  after the  date of  this Prospectus without  the prior  written consent of
William Blair & Company, L.L.C. However, William Blair & Company, L.L.C. may, in
its sole discretion and at any time  without notice, release all or any  portion
of  the securities  subject to  such lock-up  agreements. As  a result  of these
restrictions, only  the 2,881,000  shares  of Common  Stock offered  hereby  and
approximately  2,676,337 additional  shares already  outstanding will  be freely
tradeable on the date of this Prospectus, unless purchased by affiliates of  the
Company.  The remaining  2,511,371 shares of  Common Stock held  by the existing
stockholders are "restricted securities" for purposes of the Securities Act  and
may  be sold in the public  market only if registered or  if they qualify for an
exemption from registration under Rules 144, 144(k) or 701 promulgated under the
Securities Act. Upon  expiration of  the lock-up agreements  referred to  above,
holders  of approximately 1,000,686  shares of Common Stock  will be entitled to
certain registration rights  with respect to  such shares. If  such holders,  by
exercising  their  registration rights,  cause a  large number  of shares  to be
registered and  sold in  the public  market, such  sales could  have a  material
adverse  effect on the market price for  the Company's Common Stock. See "Shares
Eligible for Future Sale."
    
 
    VOLATILITY OF STOCK PRICE.  The stock market and the market prices for  many
technology   companies,  including   the  Company,   have  recently  experienced
significant price and  volume fluctuations. These  fluctuations often have  been
unrelated  to the operating  performance of the  specific companies whose stocks
are traded. Broad market fluctuations, as well as economic conditions  generally
and  in the  technology industry specifically,  may adversely  affect the market
price of  the Company's  Common Stock.  In  addition, the  market price  of  the
Company's  Common Stock could continue to fluctuate significantly in response to
variations  in  quarterly   operating  results  and   other  factors,  such   as
announcements  of new products or services by the Company or its competitors and
changes in  financial  estimates  by  securities analysts  or  other  events  or
factors.  There can be  no assurance that  the market price  of the Common Stock
will not decline below the public offering price. See "Underwriting."

                                USE OF PROCEEDS
 
   
    The net proceeds to  the Company from  the sale of  the 1,000,000 shares  of
Common   Stock  being  offered  by  the  Company  hereby  are  estimated  to  be
approximately $23.8 million based on an assumed public offering price of  $25.50
per  share  after deducting  the  underwriting discount  and  estimated offering
expenses. The principal purpose of the offering  of shares by the Company is  to
increase  the  Company's equity  capital.  The Company  expects  to add  the net
proceeds from this offering to its  general funds. Such funds will be  available
for  general corporate  purposes, including  working capital.  A portion  of the
proceeds may also be  used to acquire or  invest in complementary businesses  or
products  or to  obtain the  right to  use complementary  technologies; however,
there are no commitments or agreements with respect to any such transactions  at
the  present time. Pending use  of the net proceeds  for the above purposes, the
Company  intends  to   invest  such  funds   in  short-term,   interest-bearing,
investment-grade obligations.
    
 
    The  Company will not receive any proceeds  from the sale of Common Stock by
the Selling Stockholders.
 
                                DIVIDEND POLICY
 
    The Company  has  not paid  cash  dividends on  its  Common Stock  or  other
securities.  The Company  currently anticipates that  it will retain  all of its
future earnings for use in the expansion and operation of its business and  does
not  anticipate paying any cash dividends on its Common Stock in the foreseeable
future. Furthermore,  the  Company's  existing  credit  facility  prohibits  the
Company's  payment of dividends on the  Common Stock without either the lender's
consent or  the Company's  compliance  with the  terms  of the  credit  facility
immediately  prior to and following  any such payment. The  terms of such credit
facility require the Company to  maintain minimum assets to liabilities  ratios,
net  worth  amounts, operating  profits  and net  worth  to debt  ratios. Future
borrowing agreements may contain similar restrictions. Any future  determination
to  pay dividends will be at the  discretion of the Company's Board of Directors
and will  be  dependent upon  the  Company's results  of  operations,  financial
condition,  contractual restrictions  and other  factors deemed  relevant by the
Board of Directors.
 
                          PRICE RANGE OF COMMON STOCK
 
    The Company's Common Stock is quoted on the Nasdaq National Market under the
symbol "IQST".  The following  table sets  forth, for  the fiscal  year  periods
indicated,  the high  and low  sale prices  of the  Common Stock  as reported by
Nasdaq since the Company's initial public offering of Common Stock at $17.00 per
share on March 22, 1996.

OVERVIEW
 
    IntelliQuest  is a leading provider of quantitative marketing information to
technology companies.  The Company  also  licenses custom  proprietary  software
applications  and associated  services to technology  manufacturers for customer
registration. In 1995, approximately 42% of the Company's revenues were  derived
from  the sale  of renewable subscription-based  products, 43% from  the sale of
renewable proprietary  products and  15% from  the sale  of proprietary  project
research. See "Business -- Products and Services."
 
    The  Company was founded in 1985 to provide fee-for-service project research
on United  States technology  markets. Prior  to 1991,  the Company  focused  on
conducting proprietary research for a limited number of technology companies. In
order  to better leverage its expertise, expand its customer base and capitalize
on the growing need for international market research, the Company in 1991 began
to increase its  focus on providing  renewable subscription-based and  renewable
proprietary  products  and on  expanding its  research  coverage to  include key
international technology markets. In May 1996, the Company acquired IntelliQuest
Communications, Inc. ("IntelliQuest Communications," formerly known as  Pipeline
Communications,  Inc.), a  leading provider of  electronic customer registration
services. The transaction was accounted for as a pooling of interests; as  such,
the  Company's results of operations for all periods and financial condition for
all dates disclosed herein have been  restated to include those of  IntelliQuest
Communications.   Due  primarily   to  the   Company's  strategic   decision  to
substantially  increase  its  emphasis  on  worldwide  renewable  products   and
services,  and to a  lesser extent to the  Company's acquisition of IntelliQuest
Communications, the Company's total revenues increased from $2.2 million in 1991
to $19.1 million in 1995. Revenues  from renewable products increased from  $0.6
million  in 1991, or 25.2% of total revenues, to $16.2 million in 1995, or 84.7%
of total  revenues.  Revenues  from international  market  research,  which  the
Company  first introduced  in 1991, grew  to $5.0  million in 1995,  or 26.0% of
total revenues. Overall, the number of customers for the Company's products  and
services increased from 52 in 1991 to 130 in 1995.
 
    The  Company's  renewable  subscription-based product  revenues  are derived
substantially from  two product  lines: IntelliTrack  IQ and  Computer  Industry
Media  Study ("CIMS"). Over  80 technology companies  and publishers that target
technology purchasers subscribe to IntelliTrack IQ and/or CIMS. IntelliTrack  IQ
is   a  collection  of  16  distinct  product  modules  covering  a  variety  of
technologies and geographic  markets. Payments for  an IntelliTrack IQ  contract
are  generally made  in advance  of the  subscription period  or on  a quarterly
basis, and revenues  are recognized pro  rata over the  period of the  contract.
CIMS  is an annual study  that measures the readership  and viewership habits of
technology purchase influencers. CIMS subscribers  generally pay 50% in  advance
and  50% upon delivery of  the final study. Substantially  all CIMS revenues and
related costs are recognized upon delivery  of the final study, which  typically
occurs in the third quarter.
 
   
    The  Company's renewable  proprietary product revenues  typically consist of
revenues from  proprietary  recurring tracking  studies,  customer  registration
products  and the  IntelliQuest Brand Tech  Forum conference  (the "Forum"). The
proprietary  recurring  tracking  studies,  which  provide  the  customer   with
longitudinal  information  for  tracking designated  metrics  over  a continuous
period of time, are furnished pursuant to contracts that are generally renewable
annually. These  products are  typically  billed 50%  in  advance and  50%  upon
completion  of the contract period, and  revenues are recognized on a percentage
of completion  basis.  Revenues  from the  customer  registration  products  are
    
 
                                       15
<PAGE>
derived  from a variety of  sources, including proprietary customer registration
products and proprietary customer  satisfaction products. Customer  registration
revenues  include design fees, data medium  sales, processing fees and reporting
fees. Various payment terms are used by customer registration clients, including
50% in  advance  and  50%  upon delivery,  periodic  units  shipped/  processed,
percentage  of completion  and advance  deposits. Revenues  are recognized  on a
percentage of completion and actual units shipped/processed basis.  Sponsorships
and  conference fees  for the  Forum, which  is attended  by technology industry
marketing professionals and which addresses  issues such as managing  technology
brands  in the marketplace, are paid in advance of the event. Revenues and costs
associated with the Forum are recorded in the month of the conference.
 
    Traditional proprietary project research provides customized information  to
customers  utilizing a  variety of  proprietary models,  research techniques and
data collection methods and typically lasts  three or four months from start  to
completion. The Company is increasingly emphasizing proprietary project research
based  on the IntelliQuest Technology Panel, which  is both more timely and less
costly than traditional proprietary project research and also allows the Company
to leverage a fixed investment in panel recruitment over several projects.  Most
proprietary projects are billed 50% in advance and 50% upon delivery. Revenue is
recognized on a percentage of completion basis.
 
    The  Company's  exposure  to  foreign currency  rate  fluctuations  has been
relatively low. First, the Company generally requires payment from its customers
in U.S. dollars. Second, the Company controls vendor foreign currency risk  both
through  contractual clauses requiring vendors to  reimburse the Company for any
losses on  contracts caused  by exchange  rate fluctuations  and by  locking  in
forward currency contracts for vendor purchases and data collection costs. These
forward  contracts substantially  eliminate the  Company's exposure  to exchange
rate fluctuation risk by giving the  Company the right to purchase the  required
amount  of foreign  currency at  the exchange  rate prevailing  at the  time the
contract is entered into  rather than at  the time the payments  are due. As  of
August  31, 1996, the Company  had entered into open  forward contracts for U.S.
dollar/British  pound   sterling  transactions   with   a  notional   value   of
approximately $670,000.
 
    In  recent years, the Company has focused on increasing operating margins by
leveraging fixed overhead costs and investments in new products and  proprietary
processes.  Each subscription-based product  has a fixed  annual cost associated
with data collection and product development, with only nominal costs associated
with adding  incremental subscribers.  The customer  registration products  also
have  fixed  overhead components,  although  a significant  increase  in product
registration revenues could actually decrease the Company's overall gross margin
(due to the high  level of direct costs  associated with product  registration).
The  Company's objective is  to offset such gross  margin pressure by leveraging
product shipment and processing  fees and other  operating expenses required  to
support the customer registration programs.
 
    In  March 1996, the Company completed its initial public offering at a price
of $17.00 per  share, which resulted  in net  proceeds to the  Company of  $25.8
million. Upon the closing of the initial public offering, each outstanding share
of  the Company's Series  A and Series B  Redeemable Convertible Preferred Stock
was automatically converted into one share of Common Stock.

SIX MONTHS ENDED JUNE 30, 1996 AND JUNE 30, 1995
 
    TOTAL  REVENUES.  Total revenues increased 24.9%  in the first six months of
1996 to $8.8 million from $7.0 million in the first six months of 1995. Revenues
from subscription-based products increased  45.9% to $3.2  million in the  first
six  months of 1996  from $2.2 million  in the first  six months of  1995 due to
several factors,  including more  timely  contract closure  and an  increase  in
subscriptions.  Subscription-based  revenues from  CIMS  are deferred  until the
actual release date, which generally occurs in the third quarter. Revenues  from
renewable  proprietary products increased 24.3% to $3.9 million in the first six
months of 1996 from $3.2 million in  the first six months of 1995 due  primarily
to  increased sales of customer registration products. Revenues from proprietary
project research decreased 2.2% to $1.6 million in the first six months of  1996
from  $1.7 million in the first six months of 1995. While the number of projects
has increased, more projects have been performed utilizing the Technology Panel,
which is  a  more  cost  efficient  method  of  performing  proprietary  project
research. Revenues attributable to international market research increased 50.0%
to  $3.0 million in the first six months  of 1996 from $2.0 million in the first
six months of 1995.
 
   
    COST OF  REVENUES.    Cost  of  revenues  are  primarily  composed  of  data
collection,  labor charges,  telecommunication charges and  other costs directly
attributable to products or projects. Cost  of revenues increased 12.8% to  $3.7
million  in the  first six  months of 1996  from $3.3  million in  the first six
months of 1995. Cost of revenues decreased as a percentage of total revenues  to
42.0%  in the first  six months of  1996 from 46.6%  in the first  six months of
1995. The decrease in cost of revenues as a percentage of total revenues was due
primarily  to   leveraging   of   relatively   fixed   annual   investments   in
    
 
                                       17
<PAGE>
   
subscription-based  products over increased  subscription-based revenues, and to
decreased costs of international data  collection resulting from the opening  of
the Company's data collection facility in the U.K.
    
 
    SALES,   GENERAL   AND  ADMINISTRATIVE   EXPENSES.     Sales,   general  and
administrative  expenses  consist  primarily   of  personnel  and  other   costs
associated  with sales, marketing, administration, finance, information systems,
human resources  and  general  management.  Sales,  general  and  administrative
expenses  increased 7.8% to $2.8  million for the first  six months of 1996 from
$2.6 million  for the  first six  months of  1995. This  aggregate increase  was
primarily  due to administrative  and investor relations  expenses following the
Company's initial public offering in March 1996, transaction expenses associated
with the  acquisition of  IntelliQuest  Communications in  May 1996  (which  was
accounted  for as a pooling of interests),  expansion of the Company's sales and
marketing departments  and the  opening of  the U.K.  data collection  facility.
Sales,  general and administrative  expenses decreased as  a percentage of total
revenues to 31.9% for the first six months of 1996 from 36.9% for the first  six
months of 1995. This decrease as a percentage of total revenue was primarily due
to the Company's ability to leverage its fixed costs over a higher revenue base.
 
    PRODUCT  DEVELOPMENT EXPENSES.  Product development expenses are composed of
resources, primarily labor,  dedicated to  the development of  new products  and
proprietary  processes. Product  development expenses  increased 102.0%  to $1.7
million in the  first six  months of  1996 from $0.8  million in  the first  six
months  of 1995. Product development expenses increased as a percentage of total
revenues to 19.3% in the  first six months of 1996  from 11.9% in the first  six
months  of 1995. These increases were primarily due to the Company's development
of new Internet-related products.
 
    DEPRECIATION  AND  AMORTIZATION.    Depreciation  and  amortization  expense
increased  124.8% to $317,000 in  the first six months  of 1996 from $141,000 in
the first six months of  1995. This increase was  due primarily to a  relatively
high level of capital equipment acquisitions during the first six months of 1996
to   equip  two  new   data  collection  facilities   and  install  Company-wide
standardized computer platforms, networks and software to enable more  efficient
data communications.
 
    INCOME  TAXES.  The  Company's effective income  tax rate was  28.5% for the
first six months of 1996. This rate is below the Company's combined federal  and
state  income  tax rate  because most  of  the net  proceeds from  the Company's
initial public offering  in March  1996 were invested  in tax-free  investments.
This  reduction  was partially  offset  by the  fact  that the  Company  did not
recognize any income  tax benefit resulting  from the net  loss of  IntelliQuest
Communications. For the first six months of 1995, the Company's effective income
tax  rate was 75.4% because the Company did not recognize any income tax benefit
resulting from IntelliQuest Communications' net loss.
 
YEARS ENDED DECEMBER 31, 1995 AND DECEMBER 31, 1994
 
    TOTAL REVENUES.   Total revenues increased  36.6% in 1995  to $19.1  million
from  $14.0 million in 1994. Revenues from renewable subscription-based products
increased 31.0% to $8.1 million in 1995 from $6.2 million in 1994 due  primarily
to  the increased number of subscribers, the  higher number of products sold per
subscriber and  revenues  related  to new  international  markets  covered.  The
dollar-weighted renewal rate for renewable subscription-based products was 90.0%
in  1995. Revenues from  renewable proprietary products  increased 94.0% to $8.1
million in 1995 from $4.2  million in 1994 due  primarily to increased sales  of
customer  registration  products  and  to  increased  demand  for  international
proprietary  tracking  products.  Revenues  from  proprietary  project  research
decreased 19.7% to $2.9 million in 1995 from $3.6 million in 1994, due primarily
to   the  Company's   continuing  emphasis   on  renewable   products.  Revenues
attributable to international market research increased 68.9% to $5.0 million in
1995 from $2.9 million in 1994.
 
    COST OF REVENUES.  Cost of revenues increased 19.5% to $10.1 million in 1995
from $8.5  million  in 1994.  Cost  of revenues  decreased  as a  percentage  of
revenues  to 52.9% in 1995 from 60.5% in  1994. The decrease in cost of revenues
as  a  percentage  of  revenues  reflects  the  Company's  efforts  to  leverage
 
                                       18
<PAGE>
   
its  fixed labor costs  through its investments in  new products and proprietary
processes.  The  Company's  development  and  expansion  of   subscription-based
products  allow the Company to sell  substantially similar products to a greater
number of clients, thus increasing revenues without similarly increasing cost of
revenues. For example, the 1995 release of  CIMS did not require the same  level
of  investment per customer as the  1994 release, resulting in improved margins.
Similarly, IntelliTrack's  cost of  revenues as  a percentage  of revenues  were
lower  in 1995 than in  1994 (when the Company  expanded IntelliTrack to cover a
number of international markets). Furthermore, the Company's improvements in its
proprietary   processes   (including   more   consistently   applied    research
methodologies  and faster and more accurate data processing) reduce the costs of
research and data processing.
    
 
    SALES,  GENERAL   AND  ADMINISTRATIVE   EXPENSES.     Sales,   general   and
administrative  expenses  increased  39.5% to  $5.6  million in  1995  from $4.0
million in 1994 but remained relatively constant as a percentage of revenues  at
29.2%  and  28.6% in  1995 and  1994, respectively.  The aggregate  increase was
primarily due to  increases in  salaries and  benefits as  well as  IntelliQuest
Communications'   advertising   costs   and  legal   expenses   associated  with
finalization of certain employee and vendor contracts. In addition, the  Company
incurred  sales, general  and administrative expenses  in the  fourth quarter of
1995 of $68,000 to open its London and College Station, Texas offices.
 
    PRODUCT DEVELOPMENT EXPENSES.  Product development expenses increased  28.1%
to  $2.0 million in 1995 from $1.5 million in 1994 but decreased as a percentage
of revenues to  10.3% in 1995  from 11.0% in  1994, respectively. The  aggregate
increase  was  due to  the  Company's efforts  to  expand the  Technology Panel,
streamline  proprietary   software  and   enabling  technologies   and   provide
technological advancements to customers.
 
    DEPRECIATION  AND  AMORTIZATION.    Depreciation  and  amortization  expense
increased 19.6% to  $317,000 in 1995  from $265,000 in  1994. This increase  was
principally  due to computer  equipment purchases to  improve communications and
data processing systems  required to support  business growth and  international
expansion.
 
    INCOME TAXES.  The Company's effective tax rate was 51.2% for 1995. The rate
was  in excess  of the  combined federal and  state statutory  rates because the
Company did not recognize any income tax benefit resulting from the net loss  of
IntelliQuest  Communications. The provision for income  taxes of $2,000 for 1994
resulted principally from not  recognizing any income tax  benefit for the  1994
net loss of IntelliQuest Communications.
 
YEARS ENDED DECEMBER 31, 1994 AND DECEMBER 31, 1993
 
    TOTAL  REVENUES.  Total  revenues increased 127.5% in  1994 to $14.0 million
from $6.1 million in 1993.  Revenues from renewable subscription-based  products
increased 199.6% to $6.2 million in 1994 from $2.1 million in 1993 primarily due
to  the introduction  of CIMS  and sales  of international  IntelliTrack modules
introduced in  1993.  Revenues  from renewable  proprietary  products  increased
103.6%  to  $4.2 million  in 1994  from $2.1  million in  1993 primarily  due to
increased  sales  of  customer  registration  software,  increased  demand   for
international  proprietary  tracking  products  and  completion  of IntelliQuest
Communications' first full year of  business. Revenues from proprietary  project
research  increased 78.9%  to $3.6  million in 1994  from $2.0  million in 1993,
primarily due to increased demand for international market research and revenues
generated by IntelliQuest Communications during its first full year of business.
Revenues based on  international research  increased 368.7% to  $2.9 million  in
1994 from $626,000 in 1993.
 
    COST OF REVENUES.  Cost of revenues increased 150.8% to $8.5 million in 1994
from $3.4 million in 1993, primarily due to the increase in international market
research,  which  is  generally more  expensive  and difficult  to  conduct than
domestic  research  and  to  the   increased  level  of  expenses  incurred   by
IntelliQuest  Communications during its first full  year of business. Total cost
of revenues increased as a percentage of revenues to 60.5% in 1994 from 54.8% in
1993, due, in part, to  the Company's 1994 introduction  of CIMS, for which  the
required   initial  investment  resulted  in   the  product's  first-year  costs
approximately equalling its revenues.
 
                                       19
<PAGE>
    SALES,  GENERAL   AND  ADMINISTRATIVE   EXPENSES.     Sales,   general   and
administrative  expenses  increased  50.2% to  $4.0  million in  1994  from $2.7
million in 1993. These expenses declined as a percentage of revenues to 28.6% in
1994 from 43.3% in 1993. This decline was due to improved fixed cost  absorption
of sales, general and administrative expenses.
 
    PRODUCT  DEVELOPMENT EXPENSES.  Product development expenses increased 75.6%
to $1.5 million in 1994 from $880,000  in 1993 and decreased as a percentage  of
revenues  to 11.0% in 1994 from 14.3% in 1993. The increase in dollars spent was
primarily due to the expansion of the Company's efforts to begin developing  the
Technology  Panel,  proprietary  software  and  technological  advancements  for
customers.
 
    DEPRECIATION  AND  AMORTIZATION.    Depreciation  and  amortization  expense
increased  74.3% to $265,000  in 1994 from  $152,000 in 1993.  This increase was
principally due to purchases of telecommunications, computer and data collection
equipment.
 
    INCOME TAXES.  The  provision for income taxes  of $2,000 for 1994  resulted
principally from not recognizing any income tax benefit for the 1994 net loss of
IntelliQuest  Communications. In  1993, the  Company realized  a net  income tax
benefit of $1,000. This  benefit was the result  of the Company recognizing  the
benefits  of a net operating loss in the amount of $328,000 and other changes in
the composition of its deferred tax balances, offset by the Company  recognizing
a  net deferred tax liability of $148,000 in  May 1993 upon its change from an S
corporation to a C corporation for tax purposes.

- ----------------------------------
(1)  Pro  forma information for the quarters  ended March 31, 1995 through March
     31,  1996  assumed  conversion  of  the  Company's  redeemable  convertible
     preferred  stock into 1,853,046 shares of  Common Stock and the exercise of
     outstanding warrants  to purchase  264,480 shares  of Common  Stock,  which
     conversion  and exercise occurred in  connection with the Company's initial
     public offering in March 1996. Information  for the quarter ended June  30,
     1996  is based upon the actual historical weighted average number of common
     and common equivalent shares outstanding.
 
                                       21
<PAGE>
   
    The Company's  operating  results  in  any  particular  fiscal  period  have
fluctuated in the past and will likely fluctuate significantly in the future due
to various factors. Substantially all of the Company's subscription and customer
contracts  terminate after one year  and are renewable at  the discretion of the
customer, although no obligation to renew exists and a customer generally has no
minimum purchase commitments thereunder.  To the extent  that customers fail  to
renew  or defer their renewals from the  quarter anticipated by the Company, the
Company's quarterly results may be  materially adversely affected. In  addition,
substantially  all revenues and  expenses attributable to  CIMS for a particular
year are recognized  when the final  study is usually  completed and  delivered,
usually  in the third quarter of that  year. Delay in delivering the final study
in any given year could postpone recognition of such revenues and expenses until
the fourth quarter of such year, which would materially affect operating results
for such third and fourth quarters.  Furthermore, all costs related to CIMS  are
included  in  cost of  revenues and  none  are allocated  to sales,  general and
administrative costs, which tends  to reduce the  Company's third quarter  gross
margin  below that of other quarters. Many of the Company's customers operate in
industry segments that are becoming increasingly seasonal as technology  vendors
transition to consumer brand marketing approaches in certain markets, with sales
in  the fourth calendar quarter constituting an increasing portion of the annual
sales of  such  customers. This  may  translate  into seasonal  demand  for  the
Company's  products, particularly  the customer  registration products. Finally,
the Company's operating results may fluctuate as a result of a variety of  other
factors,  including the timing of orders from  customers, the size and timing of
the implementation of customer registration products, response rates on customer
registration products, delays in development  and customer acceptance of  custom
software  applications, product  or panel  development expenses,  new product or
service introductions or announcements by the Company or its competitors, levels
of market acceptance for new products  and services, the hiring and training  of
additional  staff and  customer demand for  market research, as  well as general
economic conditions. Because a significant portion of the Company's overhead  is
fixed in the short term and because spending commitments must be made in advance
of  revenue commitments by customers, the Company's results of operations may be
materially adversely affected in any  particular quarter if revenues fall  below
the  Company's expectations. These factors, among others, make it likely that in
some  future  quarter  the  Company's  operating  results  will  be  below   the
expectations  of securities analysts and investors,  which would have a material
adverse effect on the market price of the Company's Common Stock.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of June  30, 1996, the  Company had  cash and cash  equivalents of  $26.4
million and working capital of $27.6 million.
 
    During the six months ended June 30, 1996, the Company used $195,000 of cash
in  operating activities  while it  generated $658,000  of cash  during the same
period in the  prior year.  This decrease  in cash flow  was mainly  due to  the
timing  of payment  of income taxes  and costs  incurred in advance  of sales on
certain projects combined with typical activity in accounts receivable, unbilled
revenues and deferred revenues.
 
    The Company generated $625,000  of cash from operations  for the year  ended
December  31, 1995 as compared to $155,000  of cash from operations for the year
ended December 31, 1994. This increase in  cash generated was the result of  the
Company's   leveraging   of  its   subscription-based  products,   returns  from
investments in customer registration products and a prepayment for services on a
certain contract received by the Company during 1995.
 
    For the six months ended June 30, 1996 and 1995, net cash used in  investing
activities  was $900,000 and $251,000, respectively.  This increase in cash used
was primarily  due to  the relatively  high level  of equipment,  furniture  and
leasehold  improvement expenditures during 1996 resulting from the establishment
and expansion of new data  collection facilities and installation of  corporate-
wide  standardized computer platforms, networks and software to accommodate more
efficient data communications.
 
                                       22
<PAGE>
    Net  cash used in  investing activities increased  to $771,000 from $655,000
for the  years ended  December 31,  1995 and  December 31,  1994,  respectively,
primarily  for  the purchases  of  furniture, equipment,  computers  and related
software for use by the  Company's employees. Equipment and leasehold  purchases
in  these years were  approximately $867,000 and  $632,000, respectively. During
the year ended December 31, 1995, approximately $300,000 of this amount was used
in connection with the opening of offices in London and College Station,  Texas.
The  Company expects to  make additional purchases of  equipment as necessary to
accommodate future growth, if any.
 
    The Company has budgeted approximately $1.6 million for capital expenditures
in 1996, to be  funded primarily through cash  generated from operations. As  of
June  30, 1996, the Company had  expended $789,000 in 1996 capital acquisitions.
The Company expects that future 1996 capital expenditures will consist primarily
of telecommunications  equipment, computer  hardware and  software purchases  to
continue  to upgrade, replace  and improve existing  systems and data collection
and processing facilities.
 
    Pursuant to the  billing terms between  the Company and  its customers,  the
Company typically bills customers for products or projects before they have been
delivered.  Billed amounts  are recorded as  deferred revenues  on the Company's
financial statements and are  recognized as income when  earned. As of June  30,
1996  and  1995, the  Company  had $3.0  million  and $4.4  million  of deferred
revenues, respectively.  In  addition, when  work  is performed  in  advance  of
billing,  the Company will record this work as unbilled revenue. At each of June
30,  1996  and  1995,  the  Company  had  $1.2  million  of  unbilled  revenues.
Substantially  all deferred  and unbilled  revenues will  be earned  and billed,
respectively, within 12 months of the respective period ends.
 
    The Company maintains  a $3 million  revolving bank line  of credit to  fund
cash  requirements from time to time. Borrowings  under such line of credit bear
interest at a rate per  annum equal to the prime  rate plus one percent and  are
subject  to compliance by the Company  with certain financial covenants. At June
30, 1996, the Company was in compliance  with all such covenants and there  were
no  amounts outstanding under such line of credit. The line of credit matures on
October 30, 1996 and the Company is in negotiations to renew it.
 
    The Company believes that the net proceeds from the sale of the Common Stock
by the  Company in  this offering,  together with  cash flows  from  operations,
existing  cash balances and the  line of credit, will  be sufficient to meet its
working capital and capital  expenditure requirements for at  least the next  12
months.  Beyond that time, if the net proceeds from this offering, together with
cash flows from operations and available borrowing under the line of credit, are
not sufficient to satisfy its financing  needs, the Company may seek  additional
funding  through the sale of its  securities, including equity securities. There
can be no assurance that such funding can be obtained on favorable terms, if  at
all.

INDUSTRY BACKGROUND
 
    Increased  reliance by corporations and consumers on technology products has
led to  rapid  growth  in  the technology  industry.  Technology  companies  are
operating  in a  more complex  business environment,  characterized by increased
competition, globalization of product markets, shortened product life cycles and
increasingly complex distribution, pricing and marketing issues. Simultaneously,
the number of customers for technology products is increasing and such customers
are becoming more  diverse and segmented  in their demographic  characteristics,
technology  needs  and  buying  criteria. For  example,  small  and medium-sized
businesses are  becoming increasingly  significant  purchasers of  computer  and
networking  technologies,  and  consumer  demand  for  computers,  software  and
Internet services  is experiencing  substantial growth.  Moreover, most  leading
technology companies now compete for customers on a global basis, where customer
preferences may be heavily influenced by regional and cultural preferences.
 
    As  the technology industry  matures and increases its  focus on mass market
and consumer applications, companies have begun  to shift from a business  model
focused  primarily  on  engineering  to one  that  also  depends  on effectively
differentiating and  marketing  products  worldwide.  As  a  result,  technology
companies  are  beginning  to  market  their  products  and  services  more like
traditional packaged  goods  manufacturers  that rely  on  brand  marketing  and
advertising   programs.  Technology  companies   are  demanding  higher  quality
information  about  their  customers'  attitudes,  technology  needs,   purchase
behavior  and  brand  preferences  in order  to  track  product  performance and
customer satisfaction, measure advertising effectiveness, assess brand  strength
and   competitive  position,  determine  price  sensitivity,  and  evaluate  new
products, markets  or other  business opportunities.  Technology companies  have
also  become increasingly  focused on  the potential  lifetime value  of current
customers. As a result, many technology companies have begun to make substantial
investments in registering their customers in order to directly market  products
to them as well as to gather customer feedback and monitor customer satisfaction
levels.
 
    Survey-based research has traditionally been a valuable source of objective,
quantitative  market data to which statistical analysis can be applied. As such,
survey-based research  provides marketers  with a  basis from  which to  measure
current  market conditions and project future  outcomes. The heightened focus on
customer-based marketing  by technology  companies has  generated  significantly
increased  demand for  higher quality  data from  the marketplace.  However, the
relatively low incidence
 
                                       24
<PAGE>
of technology  purchase influencers  among the  general population  and  complex
technology  issues associated  with survey-based  market research  in technology
markets have  made  such  research  expensive,  difficult,  time  consuming  and
ultimately  prohibitive for all but the largest technology vendors to conduct on
their own.
 
    Until recently,  only a  few  market research  firms focused  on  delivering
survey-based  market  research to  the technology  industry.  As a  result, most
companies have  depended  on  market  research  firms  that  utilize  individual
research  analysts to provide  advice and opinions  about technologies, products
and markets.  Such industry  analysts typically  base their  recommendations  on
limited  customer interviews, industry contacts and direct observation of market
trends. Though opinion-based  analyst research can  offer valuable insight  into
industry  conditions and  trends, it  often lacks  the statistical  accuracy and
potential scope of more objective survey-based research.
 
THE INTELLIQUEST SOLUTION
 
   
    The Company  addresses the  need for  timely, accurate,  cost-effective  and
comprehensive  information  on  technology markets,  customers  and  products by
providing survey-based market  research data using  extensive survey  respondent
databases,  proprietary  software tools  and  innovative survey  techniques. The
Company  provides  information  based  on  consistently  applied,  statistically
rigorous data collection and analysis techniques that measure customer attitudes
and  behaviors  rather  than information  based  on the  opinions  of individual
analysts. IntelliQuest's  marketing  science  staff has  refined  and  developed
several  statistical  research  techniques  and  systems  specifically  for  the
technology marketplace. The Company has also made significant investments in the
development of these techniques and systems to assure that customers obtain high
quality research. In addition, as part  of its focus on technology markets,  the
Company  has  developed and  acquired  proprietary software  tools  and customer
registration products to more effectively collect information from international
technology respondents. The Company  has also developed  a proprietary panel  of
technology  buyers and purchase influencers  to provide customers with increased
speed and lower cost for certain types of customized data collection efforts.
    
 
    The Company  is  able  to  supply high  quality  and  cost-effective  market
tracking   information  to   its  customers  through   the  Company's  renewable
subscription-based  products.  These  databases  provide  significant  value  to
individual  customers because research costs are  shared by a number of industry
participants. As  a  result,  the  Company has  become  a  leading  provider  to
technology  companies of subscription-based products  that monitor the impact of
marketing and advertising efforts on brand strength and product positioning, and
products which assess the effectiveness of various media at reaching  technology
buyers. In addition to its subscription-based products, the Company also markets
renewable  proprietary products  and one-time  proprietary research  projects to
individual  customers.  These  products   utilize  specialized  techniques   and
proprietary  tools  to deliver  sophisticated databases  of market  and customer
information that address specific  longitudinal and point-in-time  international
business  issues. In  addition, the  Company's electronic  customer registration
products also facilitate technology companies' direct marketing initiatives  and
create new electronic commerce opportunities.

BUSINESS STRENGTHS
    The Company believes the following factors have been of principal importance
in  its  ability  to achieve  its  present  position as  a  leading  provider of
survey-based worldwide market research to technology companies.
 
   
    FOCUS ON TECHNOLOGY MARKETS.  Since  its founding in 1985, IntelliQuest  has
focused on meeting the specialized market research needs of technology companies
and  publishers who market to technology  advertisers. The Company believes that
its ability to  cost-effectively provide consistent  information regarding  both
domestic  and  international  technology  markets  differentiates  it  from  its
competitors and enhances the Company's ability to capitalize on the trend  among
multinational  technology vendors to seek worldwide market research. The Company
has established relationships with many leading technology companies,  including
3Com,  3M, Apple Computer,  AT&T, Bay Networks,  Compaq Computer, Dell Computer,
Digital Equipment,  Epson, Hewlett-Packard,  IBM, Intel,  MicroHelp,  Microsoft,
Netscape,  Novell, Symantec, Texas Instruments, Toshiba and US West. The Company
has also established relationships with leading publishers, including Dow Jones,
Gannett, Time Warner and Ziff-Davis, who market to technology advertisers.
    
 
   
    EMPHASIS ON  RENEWABLE PRODUCTS.   In  1995, 84.7%  of the  Company's  total
revenues  were  generated  from  the  sale  of  renewable  subscription-based or
renewable proprietary products.  Due to  the strategic  value of  IntelliQuest's
products  and services, its innovative use  of proprietary technology to collect
and analyze  information and  the Company's  reputation for  excellent  customer
service,  the Company  averaged dollar-weighted  renewals for subscription-based
products of 84% over the three year period from 1993 through 1995. Eight of  the
Company's  ten  largest  customers  in  1994 were  also  among  its  ten largest
customers in 1995.
    
 
   
    INVESTMENT IN  PROPRIETARY TECHNOLOGY.   The  Company has  made  substantial
investments in proprietary technology for survey administration, data collection
and  data  analysis.  IntelliQuest  was  a  pioneer  in  the  use  of disk-based
interactive survey  techniques,  which  are  used  to  gather  information  from
technology  purchasers and users. The Company  has made a substantial investment
in ReplyDisk,  its proprietary  survey  software, which  allows the  Company  to
easily   create  customized   interactive,  graphical   and  multi-media  survey
applications. The  Company  has  also  used the  ReplyDisk  platform  to  create
off-the-shelf  survey software applications  such as ReplySat,  which provides a
turnkey solution for measuring customer  satisfaction and reporting results.  In
May  1996,  the  Company further  expanded  its offering  of  proprietary survey
software  by   acquiring   IntelliQuest  Communications,   Inc.   ("IntelliQuest
Communications,"  formerly known as Pipeline Communications, Inc.). IntelliQuest
Communications is a  leading provider  of electronic  customer registration  and
marketing  services  for a  number of  leading  computer hardware,  software and
peripheral companies. IntelliQuest  Communications has  developed a  proprietary
frame  relay network that  allows electronic customer  registration from over 90
countries and 400  cities worldwide  as well  as registration  via Internet  Web
sites.  The  Company has  also invested  in  data communication  technologies to
increase the efficiency of  data collection using  the disk-based approach.  The
Company  is  currently  developing NetQuest,  which  will allow  the  Company to
administer interactive  surveys  on  the  Internet.  Additionally,  the  Company
recently  completed the development of IntelliTab,  a customized version of SPSS
statistical reporting software, to give customers the ability to easily generate
tables and graphs  from electronic databases  provided by the  Company for  both
subscription-based and renewable proprietary products.
    
 
   
    FOCUS ON LEVERAGING PROPRIETARY TECHNOLOGIES AND PRODUCTS.  In recent years,
the Company has been able to better leverage its fixed expense base. The Company
believes  that this  improvement is  attributable, in  part, to  its substantial
investments in its proprietary survey technologies, data collection and analysis
methodologies, renewable subscription-based  products and  Technology Panel.  In
addition,  the Company  has also realized  improved operating  efficiency by (i)
pursuing sales penetration of  technology vendors not  previously served by  the
Company,   but   whose   products  were   already   tracked  as   part   of  its
subscription-based products, (ii)  capitalizing on a  "consortium" approach  for
designing  new subscription-based products,  and (iii) marketing  new modules of
existing products to  the Company's  current customers. In  1995, the  Company's
operating  income  as  a percentage  of  revenues  increased to  6.0%,  based on
revenues of $19.1 million and operating  income of $1.1 million, compared to  an
operating  loss  as a  percentage of  revenues of  5.0% in  1992, based  on $3.9
million in revenues and an operating loss of $196,000.

GROWTH STRATEGY
    The Company's growth strategy includes the following key elements.
 
    INCREASE MARKETING TO EXISTING CUSTOMERS.  Many of IntelliQuest's  customers
are  diversified multinational technology companies. The Company typically works
with some,  but not  all, of  the  business units  within these  companies.  The
Company  believes  that  opportunities  exist  to  leverage  its  expertise  and
reputation to  expand  its  presence  among other  business  units  of  existing
customers.  In addition, many of IntelliQuest's subscription-based and renewable
proprietary products enable the  Company to market  to customers more  specific,
customized  research projects.  Many of the  technology companies  served by the
Company are also  experiencing significant growth  and increasing their  overall
market  research budgets. The  Company is increasing  its marketing efforts with
respect to these customers in order to capture a portion of the increased demand
by such companies for market research.
 
   
    EXTEND PRODUCTS  AND  SERVICES  TO  NEW  CUSTOMERS  AND  RELATED  TECHNOLOGY
MARKETS.   The Company believes that  its experience and reputation in providing
high-quality, cost-effective market research  information to leading  technology
and  publishing companies  will enable  it to  market its  existing products and
services to new  customers. In  particular, the  Company has  an opportunity  to
pursue  sales penetration  of technology  vendors not  previously served  by the
Company,  but   whose   products  were   already   tracked  as   part   of   its
subscription-based  products. In  addition, while  the Company  has historically
derived a significant percentage of its revenues from customers in the  computer
industry, primarily manufacturers of personal computers and related hardware and
software, the Company has begun to target related technology markets such as the
data  communications,  on-line  services,  Internet  and  interactive  new media
markets.
    
 
    DEVELOP  INTERNET-BASED   RESEARCH   TOOLS   AND   OTHER   NEW   INFORMATION
SERVICES.   The  use of the  Internet for e-mail  communications and information
dissemination (through Web sites) has grown rapidly over the past several years.
The Company is seeking  to capitalize on this  growth by expanding its  recently
introduced  Internet-based research tools  and information services  such as Web
site surveys and a  survey to measure Internet  and on-line service usage  among
technology  purchase  influencers. The  Company  also intends  to  develop other
products and services that address specific customer demands and expand the  use
of  its existing products and services to  enable the Company to better leverage
its proprietary technologies and infrastructure.
 
    DEVELOP ANCILLARY SERVICES TO CUSTOMER REGISTRATION.  IntelliQuest  believes
it  can leverage its  position in the customer  registration business to develop
several ancillary  services, such  as customer  satisfaction tracking,  database
management,   database  enhancement,  and   electronic  marketing  services.  In
addition, the Company believes the opportunity  may exist to license the  rights
to  customer  registration  information and  consolidate  such  information into
low-cost marketing data products.
 
    EXPAND INTERNATIONALLY.   Demand  for technology  products in  international
markets  has increased significantly in recent years. As the Company's customers
expand  their  marketing  activities  worldwide,  the  Company  has  experienced
increased  demand  for  market research  information  and  customer registration
relating to international  markets. Accordingly,  the Company  is expanding  its
overseas market research capabilities. The Company recently opened an office and
data collection facility in London and has established research and distribution
affiliate  relationships with  companies covering Japan,  Europe, Canada, Mexico
and Latin America.
 
   
    EXPAND THROUGH STRATEGIC BUSINESS COMBINATIONS.  IntelliQuest believes  that
through   continued  growth,  it   will  be  better   positioned  to  provide  a
comprehensive set  of  survey-based  market  research  to  a  broader  group  of
customers.  The Company  believes that  the market  research industry  is highly
fragmented and that opportunities exist to expand through acquisitions or  other
strategic  business combinations. The Company plans to consider acquisitions of,
alliances with, and investments in  companies that provide products or  services
not  offered by the Company, have  strategic customer relationships, are located
in  attractive  geographic  locations  or  have  proprietary  technologies.  For
example,  in May 1996,  the Company acquired  IntelliQuest Communications, whose
proprietary electronic customer registration products will significantly  expand
the Company's offering of electronic registration services.

- ------------------------------
   
    *     Through its  offices in  Austin and  College Station,  Texas, Atlanta,
Georgia and London and affiliates  abroad, the Company provides market  research
data  on the  following countries:  the United  States, Canada,  Mexico, Brazil,
France, the U.K., Germany, Italy and Japan.

    While the dynamics of each area are distinct, sales to customers in a  given
area  often generate sales to customers in the other areas. For example, many of
the Company's  subscription-based  products  grew  out  of  proprietary  project
research  initially developed for multiple customers. Conversely, many renewable
subscription-based products and/or  renewable proprietary  products provide  the
foundation for more specific proprietary project research.
 
RENEWABLE SUBSCRIPTION-BASED PRODUCTS
 
    Renewable  subscription-based  products  are  designed  to  help  technology
vendors undertake more  systematic management  of their  branding and  marketing
efforts. Because research costs are shared by a number of industry participants,
high quality information can be provided at cost-effective prices.
 
    INTELLITRACK  IQ.  IntelliTrack  IQ is a  family of subscription-based brand
tracking  studies  delivered  monthly  or  quarterly  via  statistical   tables,
graphical  reports and diskette. Through over  45,000 annual interviews with key
purchase  influencers  of  computer-related  equipment,  IntelliTrack   provides
continuous international brand awareness, consideration and purchase data.
 
    IntelliTrack  is sold through annual  subscriptions for a customer-specified
number of product  and geographic market  modules. Since 1991,  the Company  has
increased  the number  of modules  from two to  16. The  product markets tracked
include   business-to-business   markets   for   desktop   personal   computers,
portable/notebook  personal  computers, workstation  computers,  printers, color
printers, networking equipment and personal  computers and printers used in  the
home.  The geographic markets tracked include the United States, Canada, Mexico,
Brazil, the U.K., France, Germany, Italy and Japan.
 
    IntelliTrack also offers omnibus and recontact services. The omnibus service
allows  customers  to  add  questions  to  the  IntelliTrack  survey,  providing
additional  in-depth data  customized to customers'  individual needs. Recontact
studies allow customers  direct access to  original IntelliTrack respondents  so
that  research  projects  can be  conducted  with specific  target  groups. Both
services provide  a cost-effective  alternative to  small, focused,  proprietary
studies.
 
    COMPUTER  INDUSTRY MEDIA  STUDY (CIMS).   The Company  maintains and markets
CIMS, one of the leading databases of media readership and viewership habits  of
both  business  and  household  technology purchase  influencers  in  the United
States. Conducted on an annual basis,  the research is designed to provide  both
advertisers and media companies with objective, comparable information about how
to efficiently target advertising at key buying groups. Subscribers include most
major  technology-focused publishing  groups as well  as top  advertisers in the
categories measured,  which include  desktop  PCs, notebook  PCs,  workstations,
microprocessors,   printers,   peripherals,  applications   software,  operating
systems, LAN  hardware/software,  Internet  working,  wide-area  networking  and
communications  products. Subscribers may purchase by customer segment (business
or home) or by  product category. Databases are  delivered via on-line  services
which incorporate media models that allow advertisers to develop media schedules
which seek to maximize reach against target buying audiences. In addition to the
advertising  information, the  scope of the  study (10,000  business surveys and
5,000 home surveys) makes CIMS a comprehensive annual benchmark of market trends
in both buying patterns and media behavior.
 
   
    WORLDWIDE INTERNET TRACKING STUDY (WWITS).  The Company recently  introduced
WWITS, a subscription-based study that tracks Internet and on-line service (OLS)
usage  in the United States and Europe. Conducted quarterly in the United States
and annually  in France,  Germany and  the U.K.,  this study  provides what  the
Company  believes is the most accurate and comprehensive measurement of the size
and growth of  the Internet  and OLS  user population.  Additionally, the  study
monitors the on-line activities of Internet and OLS users, including their brand
preferences  and satisfaction levels.  Subscribers to the  study include leading
providers of hardware, software  and services to  the Internet market.  Specific
product  categories tracked include on-line services, Internet access providers,
browsers, search engines,  hardware for accessing  the Internet, and  electronic
commerce.  Databases  are  delivered via  hard  copy reports  and  in electronic
database format. As with IntelliTrack,  WWITS also offers omnibus and  recontact
services.

RENEWABLE PROPRIETARY PRODUCTS
 
    To  meet  the unique  information needs  of certain  customers, IntelliQuest
designs and manages ongoing  market feedback systems  to deliver consistent  and
regular proprietary information databases.
 
    CUSTOMER  REGISTRATION  PRODUCTS.   IntelliQuest offers  innovative customer
registration  software  products   that  provide  technology   vendors  with   a
cost-effective  way of  capturing, analyzing and  managing customer information.
The  Company's  customer  registration  products  include  both  customized  and
standard  turnkey programs. IntelliQuest offers  a complete solution with regard
to response media including customer registration responses via modem, diskette,
e-mail, fax,  interactive voice  response or  print. Through  the use  of  these
technologies,  IntelliQuest has been able to achieve customer registration rates
that the Company believes are significantly higher than those achievable through
traditional  approaches   and  collect   substantially  more   information   per
questionnaire in comparison to the questionnaires used in those approaches.
 
   
    Extensive experience in computer-based survey research techniques led to the
Company's   development  of   ReplyDisk,  the   Company's  proprietary  software
application for conducting registrations electronically. ReplyDisk provides  for
fully  interactive questionnaire  logic, with  complete multimedia capabilities,
including the ability to incorporate voice, video, and high resolution  graphics
into  registration  products.  Hardware  manufacturers  typically  pre-load  the
software on their products so that the registration questionnaire  automatically
appears when the product is configured. In addition to collecting customer data,
ReplyDisk  can also be customized to incorporate electronic "infomercials," thus
allowing customers  to view  additional  support or  warranty options  or  order
products from an electronic catalog.
    
 
   
    CUSTOMER   SATISFACTION  TRACKING.     The   Company  markets   ReplySat,  a
ReplyDisk-based customer  satisfaction product  that provides  customers with  a
cost-effective  program for tracking customer attitudes and satisfaction towards
their  products.  The   Company  provides  a   turnkey  solution,  including   a
pre-programmed  and  fully customizable  survey  application, as  well  as fully
automated data collection and reporting  systems. Under this program,  customers
subscribe  to the service on  a quarterly or semi-annual  basis and receive data
via statistical tables, graphical reports  and diskettes. The program  evaluates
all aspects of the customer's buying experience including salespeople, features,
support,  service,  and  delivery.  IntelliQuest's  proprietary  software allows
customers  to  monitor  a  full  range  of  satisfaction  variables  by   asking
individuals  questions relevant to their own buying experience. Regular tracking
of satisfaction  allows IntelliQuest's  customers  to understand  factors  which
drive  satisfaction, monitor changes in product quality and service programs and
appropriately position products.  Customized customer  satisfaction studies  can
also  evaluate competitors' customer  satisfaction, highlighting areas requiring
relative  improvement  and  identifying  opportunities  to  exploit  competitive
advantages.
    
 
    LONGITUDINAL  TRACKING  STUDIES.    IntelliQuest  also  provides proprietary
customized brand,  advertising,  product  and customer  tracking  programs.  The
Company creates proprietary tracking systems for certain customers, based on the
IntelliTrack methodology, that monitor unique product or market segments and use
IntelliTrack  data for benchmarking and performance evaluation. The Company also
tracks the  effectiveness  of  specific  advertising  campaigns  on  an  ongoing
proprietary  basis  for  certain  customers. Finally,  the  Company  designs and
implements customized product and customer tracking research to follow  products
and customers through all phases of the product life cycle.
 
PROPRIETARY PROJECT RESEARCH
 
    In   addition  to  subscription-based  products  and  renewable  proprietary
products,  IntelliQuest  is  a  leading  provider  of  the  following  types  of
proprietary market research studies to technology companies.
 
                                       30
<PAGE>
    PROPRIETARY RESEARCH
 
    MARKET OPPORTUNITY ASSESSMENT.  IntelliQuest's market opportunity assessment
enables  companies  to  explore  the potential  and  pitfalls  of  new products,
channels or services.
 
    MARKET SEGMENT ANALYSIS.  IntelliQuest's market segmentation studies  assist
customers  in identifying segments with varying needs, quantifying the sizes and
potential economic opportunities of the segments, describing the composition  of
each  segment,  analyzing  each  segment's sources  of  product  information and
evaluating alternative marketing communications messages.
 
    PRICING/PROFITABILITY RESEARCH.   Through close work  with top academic  and
industry   researchers,  the  Company  has  refined  a  methodology  to  collect
information on price  and its  relationship to other  product attributes.  Using
this  data, the  Company is  able to  model various  pricing strategies  for its
customers' products.
 
    PUBLISHER STUDIES.   IntelliQuest provides customized  marketing studies  to
technology magazine publishers to promote and sell advertising.
 
    TECHNOLOGY PANEL
 
    The  Company's  Technology Panel  consists  of approximately  16,000 persons
involved in corporate purchases of technology goods and services who have agreed
to participate in the Company's ongoing survey research projects. The Technology
Panel provides  the Company  with pre-recruited  technology respondents  from  a
variety  of corporate  functional areas  and product  categories and  rapid data
collection tools  to enable  cost-effective research  among specific  technology
respondent groups.
 
   
    The  Technology Panel currently includes  respondents from the United States
and several major  European countries and  eventually is expected  to cover  all
major  global markets of interest to  IntelliQuest's customers. In addition, the
Company plans to utilize its Internet survey software, which is currently  being
developed,  to  gather electronic  surveys  from panel  participants.  This will
benefit customers by  improving turnaround  time and more  closely aligning  the
research process with the shortening life-cycles of technology products.
    
 
    Research   panels  are  valuable  sources   of  technology  market  research
information. Panel research is  well suited for  (i) tracking customer  behavior
and  attitudes, (ii) testing new  products, (iii) conducting proprietary studies
with hard to  find respondents,  (iv) obtaining time  sensitive information  for
tactical decision making, (v) obtaining time sensitive competitive feedback, and
(vi) testing marketing campaigns or advertising concepts.
 
CUSTOMERS
 
    During  1995, the Company served approximately 100 customers. IntelliQuest's
technology vendor  customers  include 3Com,  3M,  Apple Computer,  AT&T,  Compaq
Computer,   Dell  Computer,  Digital  Equipment,  Hewlett-Packard,  IBM,  Intel,
MicroHelp, Microsoft, Netscape, Novell, Symantec, Texas Instruments, Toshiba and
US West. IntelliQuest also tracks over 60 publications for numerous  publishers,
including  Dow  Jones,  Gannett,  Time  Warner  and  Ziff-Davis,  who  market to
technology advertisers.  The  Company's  customers  have  increasingly  demanded
consistent  international market information. Revenues from international market
research, which the Company  first introduced in 1991,  grew to $5.0 million  in
1995, or approximately 26.0% of total revenues.
 
   
    In  1995,  84.7%  of the  Company's  total  revenues were  derived  from the
Company's subscription-based products  and contracts  for renewable  proprietary
products,  and the Company expects  that a material portion  of its revenues for
the foreseeable  future will  continue  to be  derived  from such  sources.  The
remainder of the Company's revenues were derived from custom purchase orders for
proprietary  project  research.  See "Management's  Discussion  and  Analysis of
Financial Condition and Results of Operations."
    
 
   
    The Company's two largest customers, Microsoft and IBM, accounted for  15.1%
and  10.5%, respectively, of 1995 revenues.  No other customer accounted for 10%
or more of revenues in 1995.
    
 
                                       31
<PAGE>
Substantially all  of the  Company's subscriptions  and customer  contracts  are
renewable  annually  at  the  option of  the  Company's  customers,  although no
obligation to renew  exists and  a customer  generally has  no minimum  purchase
commitments  thereunder.  In  addition, there  is  significant  consolidation of
companies in the technology industries served by the Company, a trend which  the
Company  believes will continue. Consolidation among the Company's top customers
could adversely affect customer budgets for the Company's products and services.
No assurances can be given that the Company will maintain its existing  customer
base or that it will be able to attract new customers.
 
    IntelliQuest  is committed  to providing high  quality market  research in a
cost-effective, consistent and user-friendly manner to its customers.  Depending
on  their specific preferences,  customers receive substantial  support from the
Company's  customer  development  representatives,  its  account  team  and  its
marketing  science  department.  In  addition,  the  Company  regularly solicits
extensive  feedback  from  customers  regarding  their  satisfaction  with   the
Company's products and services. The Company respects the confidentiality of the
products, services and projects provided to each of its clients.
 
SALES AND MARKETING
 
    IntelliQuest  has historically  generated most  of its  new business through
customer referrals  supplemented by  its own  sales and  marketing efforts.  The
Company  believes that its success to date in generating new business has been a
function primarily  of  its  reputation  for  providing  timely,  high  quality,
cost-effective  information  to its  customers  and its  investment  in customer
service and support. The  Company has historically  maintained a small,  focused
direct  sales force to  market the Company's products  and services to potential
new customers, and has only recently begun to develop a formal sales  management
structure.  The Company  has recently  hired a Vice  President of  Sales and has
increased its sales force to  10 persons as of  September 23, 1996. The  Company
also trains and encourages all of its employees to monitor the information needs
of  existing customers in order to  provide additional products and services. In
addition, the Company's  senior management actively  participates in  developing
and maintaining customer relationships.
 
    The  Company's sales  cycle varies  depending on  the particular  product or
service being marketed. For subscription-based products, renewals are  generally
secured on an annual basis, typically in the fourth calendar quarter.
 
   
    The  Company's primary marketing event is the annual IntelliQuest Brand Tech
Forum (the "Forum"), attended by over 300 of the technology industry's marketing
professionals. The conference features outside  speakers on a variety of  topics
related to branding and technology marketing, and provides a public showcase for
the  Company's products and services. The 1996  Forum will be hosted by the Wall
Street Journal  and sponsored  by  CMP, Beyond  Computing, Advertising  Age  and
Alexander  Communications. In addition,  the Company sponsors  a variety of user
conferences for  subscribers  to  its information  products.  These  conferences
provide   customer  feedback  on  potential  product  improvements  and  service
enhancements.
    
 
    Publishers frequently contract with IntelliQuest to conduct research that is
published or distributed to technology companies. The Company also provides data
for editorial use, including providing USA Today with monthly survey information
for the USA Today/IntelliQuest Technology Poll.
 
    As the Company develops new products and services targeted at  broader-based
market  segments, it  will need  to continue to  expand its  direct sales force.
There can be no assurance that the Company will be able to successfully  develop
or  manage such a  sales force. See  "Risk Factors --  Expansion of Direct Sales
Force."
 
PRODUCT DEVELOPMENT AND TECHNOLOGY
 
    The  Company  is  actively  developing  new  subscription-based  information
products.  The Company  focuses its product  development efforts  in areas where
there is a demonstrated customer demand for consistent worldwide market research
but where  quality research  is  cost prohibitive  unless shared  among  several
customers.
 
                                       32
<PAGE>
    The  Company is also  investing in enabling  technologies which increase the
quality and efficiency of the  data collection process. This includes  continued
enhancements  to the  Company's proprietary ReplyDisk  software to  enable it to
operate on the Web. The Company also anticipates using the software for internal
use (to improve  data collection  cost efficiencies)  as well  as licensing  the
software  so that  any company  with a  site on  the Web  can conduct electronic
survey research. Additionally, the Company  expects to use the Internet  version
of  ReplyDisk to survey  the Technology Panel,  thereby lowering data collection
costs and further reducing turnaround time on panel studies.
 
    The Company is also developing tools to further automate existing  processes
for  data collection  and analysis. This  includes software  that integrates the
survey application with reporting packages, an automated
graphical-user-interface-based survey  builder to  enhance the  productivity  of
programmers  in several aspects of the  data collection process, and IntelliTab,
the Company's recently introduced statistical reporting software.
 
    IntelliQuest Communications is also continuing  to develop new products  and
technologies,  such as  its frame relay  network, which can  now process on-line
calls in over  90 countries and  400 cities through  the Internet.  Intelliquest
Communications  also recently announced  a new product  called IntelliCIS, which
provides real time  customer and  market research  information to  manufacturers
based on worldwide customer registrations.
 
COMPETITION
 
    The  technology-focused market research industry  is highly competitive. The
principal bases of competition in  the Company's business are quality,  industry
knowledge,  data delivery, geographic  coverage, cost-effectiveness and customer
service. The Company has traditionally  competed directly with relatively  small
local  providers of survey-based technology-focused market research. The Company
also competes  directly  with third  party  providers of  customer  registration
software  (such as  KAO Infosystems  Company) as  well as  vendors' own customer
registration  software.  In  addition,  the  Company  competes  indirectly  with
significant  providers of (i)  analyst-based, technology-focused market research
(such as Gartner Group,  Inc., META Group, Inc.  and Forrester Research,  Inc.);
(ii)  survey-based, general market  research (such as  A.C. Nielsen Company, NFO
Research, Inc., Information Resources Inc. and  The NPD Group, Inc.); and  (iii)
analyst-based,  general  business  consulting.  Although  only  a  few  of these
competitors  have  to  date  offered  survey-based,  technology-focused   market
research  that competes directly with the  Company's products and services, many
of these competitors have substantially greater financial, information gathering
and marketing resources  than the  Company and  could decide  to increase  their
resource  commitments to the Company's market. Moreover, each of these companies
currently competes  indirectly,  if not  directly,  for funds  available  within
aggregate industry-wide market research budgets. There are few barriers to entry
into  the Company's market, and the Company expects increased competition in one
or more  market  segments  addressed  by the  Company.  Such  competition  could
adversely  affect  the  Company's operating  results  through  pricing pressure,
required increased marketing expenditures and loss of market share, among  other
factors.  There can be  no assurance that  the Company will  continue to compete
successfully  against  existing  or  new  competitors.  See  "Risk  Factors   --
Competition."
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
    The  Company's success  is in part  dependent upon  its proprietary software
technology, research methods, data analysis techniques, and internal systems and
procedures that  it  has  developed  specifically  to  serve  customers  in  the
technology  industry. The Company  has no patents; consequently,  it relies on a
combination of  copyright, trademark  and  trade secret  laws and  employee  and
third-party  non-disclosure  agreements  to  protect  its  proprietary  systems,
software and procedures. There can be no  assurance that the steps taken by  the
Company   to  protect  its  proprietary  rights  will  be  adequate  to  prevent
misappropriation of such  rights or  that third parties  will not  independently
develop functionally equivalent or superior systems, software or procedures. The
Company believes that its systems, software and procedures and other proprietary
rights  do not infringe the proprietary rights of third parties. There can be no
assurance, however,  that  third parties  will  not assert  infringement  claims
 
                                       33
<PAGE>
against  the Company in the future or that  any such claims will not require the
Company to  enter into  materially  adverse license  arrangements or  result  in
protracted and costly litigation, regardless of the merits of such claims.
 
EMPLOYEES
 
    As  of September 23, 1996, IntelliQuest employed a total of 168 persons on a
full-time basis, consisting of 50 in custom and syndicated media tracking, 34 in
syndicated tracking, 39 in  other technical services,  19 in client  development
and  marketing and  26 in administrative  functions. Of these  employees, 29 are
software  programmers  or  database  specialists.  The  Company  also   employed
part-time  individuals in  its field  operations, representing  approximately 75
full-time equivalent employees. None of the Company's employees are  represented
by  a collective  bargaining agreement.  The Company  considers its relationship
with its employees to be good.
 
FACILITIES
 
    The Company's  headquarters are  located  in 22,300  square feet  of  leased
office  space in Austin, Texas.  This facility accommodates research, marketing,
sales, customer support and corporate administration. The lease on this facility
expires in January 1998.  The Company leases additional  office space in  Austin
and  College Station, Texas,  Atlanta, Georgia and  London. The Company believes
that its  existing  facilities are  adequate  for  its current  needs  and  that
additional facilities can be leased to meet future needs.

DIRECTOR COMPENSATION
 
    All  directors hold office until the next annual meeting of the stockholders
or until their successors have  been elected and qualified. Directors  currently
receive  no compensation for their service on  the Board of Directors but may be
reimbursed for reasonable expenses incurred in connection with their services as
directors. In addition, under the 1996  Director Option Plan, directors who  are
not  employees  of  the Company  receive,  at  the discretion  of  the  Board of
Directors, options to purchase shares of Common Stock upon joining the Board  of
Directors.   Thereafter,  each  non-employee  director   will  receive,  at  the
discretion of the Board of Directors, an  annual grant of an option to  purchase
shares of
 
                                       35
<PAGE>
Common  Stock. See "Management -- Employee Benefit Plans -- 1996 Director Option
Plan." The Company also does  not provide additional compensation for  committee
participation  or special assignments of the  Board of Directors. Officers serve
at the discretion of the Board of Directors.
 
BOARD COMMITTEES
 
    The Board of Directors has a Compensation Committee and an Audit  Committee.
The  Compensation  Committee makes  recommendations  to the  Board  of Directors
concerning salaries and  incentive compensation for  the Company's officers  and
employees  and  administers  the Company's  stock  and option  plans.  The Audit
Committee evaluates the Company's internal audit and control functions.
 
COMPENSATION COMMITTEE INTERLOCKS
 
    The Compensation Committee and the Audit Committee of the Board of Directors
each consist of William Wood  and Lee Walker, neither of  whom is an officer  or
employee  of the Company.  No member of the  Compensation Committee or executive
officer of the Company has a relationship that would constitute an  interlocking
relationship with executive officers or directors of another entity.
 
LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company's Certificate of Incorporation limits the liability of directors
to  the maximum  extent permitted  by Delaware  law. Delaware  law provides that
directors of a corporation  will not be personally  liable for monetary  damages
for  breach  of  their  fiduciary  duties  as  directors,  except  for liability
attributed to (i) any breach of their duty of loyalty to the corporation or  its
stockholders,  (ii)  acts  or  omissions  not  in  good  faith  or  that involve
intentional misconduct or a knowing violation of law, (iii) unlawful payments of
dividends or unlawful stock  repurchases or redemptions  as provided in  Section
174  of the Delaware General Corporation Law, or (iv) any transaction from which
the director derived an improper personal benefit.
 
    The Company's Bylaws provide that the Company shall indemnify its  directors
and  executive officers and  may indemnify its other  officers and employees and
other agents to the fullest extent  permitted by law. The Company's Bylaws  also
permit  the  Company to  secure insurance  on behalf  of any  officer, director,
employee or other agent for any liability  arising out of his or her actions  in
such capacity.
 
    The  Company  has entered  into agreements  to  indemnify its  directors and
officers,  in  addition  to  indemnification  provided  for  in  the   Company's
Certificate  of Incorporation and Bylaws.  These agreements, among other things,
indemnify the Company's directors and  officers for certain expenses  (including
attorneys'  fees), judgments, fines and settlement  amounts incurred by any such
person in any action or proceeding, including  any action by or in the right  of
the  Company, arising out of such person's  services as a director or officer of
the Company, any subsidiary of the Company or any other company or enterprise to
which the person provides  services at the request  of the Company. The  Company
believes  that  these provisions  and agreements  are  necessary to  attract and
retain qualified directors and officers.
 
    At present,  there is  no  pending litigation  or proceeding  involving  any
director, officer, employee or agent of the Company. The Company is not aware of
any  threatened litigation or proceeding  that might result in  a claim for such
indemnification.

INCENTIVE PROGRAM

goals and objectives.
 
EMPLOYEE BENEFIT PLANS
 
AMENDED 1993 IQI CORP. STOCK OPTION PLAN
 
   
    Under the Company's  Amended 1993  IQI Corp.  Stock Option  Plan (the  "1993
Option  Plan"),  as of  August 31,  1996,  135,500 shares  of Common  Stock were
subject to outstanding options at a weighted average exercise price of $0.25 per
share. No further options  will be granted under  the 1993 Option Plan.  Options
under the 1993 Option Plan generally become exercisable over a vesting period of
five  years and as  of August 31,  1996, outstanding options  to purchase 18,571
shares of  Common Stock  had vested.  Options under  the 1993  Option Plan  were
issuable  to  employees of  the Company  and were  intended as  "incentive stock
options" intended to qualify for  certain favorable tax treatment. The  exercise
price  of each incentive stock option is at least equal to the fair market value
of the Common Stock on the date of grant.
    
 
1996 STOCK PLAN
 
   
    The Company has reserved an aggregate of 300,000 shares of Common Stock  for
issuance  under its 1996  Stock Plan (the  "1996 Plan"); as  of August 31, 1996,
168,094 shares of Common Stock were subject to outstanding options at a weighted
average exercise price  of $15.53 per  share. No outstanding  options under  the
1996  Plan had vested  as of August 31,  1996. The 1996 Plan  was adopted by the
Board of Directors and approved by  the stockholders in February 1996. The  1996
Plan  will terminate in February 2006 unless  terminated earlier by the Board of
Directors. The  1996  Plan provides  for  grants  of options  to  employees  and
consultants   (including  officers  and  directors)   of  the  Company  and  its
subsidiaries. The 1996 Plan may be administered by the Board of Directors or  by
a committee
    
 
                                       38
<PAGE>
appointed  by  the Board,  in  a manner  that  satisfies the  legal requirements
relating to the  administration of stock  plans under all  applicable laws  (the
"Administrator"). The 1996 Plan is administered by the Compensation Committee.
 
    The  exercise price of options granted under  the 1996 Plan is determined by
the Administrator. With  respect to  incentive stock options  granted under  the
1996  Plan, the exercise price  must be at least equal  to the fair market value
per share of the Common  Stock on the date of  grant, and the exercise price  of
any  incentive stock options granted to a  participant who owns more than 10% of
the voting power of all classes of the Company's outstanding capital stock  must
be  equal to at least 110%  of the fair market value  of the Common Stock on the
date of grant. The maximum term of an option granted under the 1996 Plan may not
exceed ten years from the date of grant (five years in the case of a participant
who owns more  than 10%  of the  voting power of  all classes  of the  Company's
outstanding  capital stock).  In the event  of the termination  of an optionee's
employment or  consulting arrangement,  options may  only be  exercised, to  the
extent  vested as of the date of termination, for a period not to exceed 90 days
(12 months  in the  case of  termination as  a result  of death  or  disability)
following  the date of termination. Options may not be sold or transferred other
than by will  or the  laws of  descent and  distribution, and  may be  exercised
during the life of the optionee only by the optionee.
 
    Options  to  be  granted  under  the 1996  Plan  generally  vest  and become
exercisable, assuming continued service as an employee or consultant, at a  rate
of  40% of the shares subject to an  option vesting on the second anniversary of
the commencement of vesting date and 20% of the shares on each of the next three
anniversaries thereafter, such that all shares under an option vest in full five
years from the  commencement of vesting  date assuming continued  service as  an
employee or consultant. Options outstanding under the 1996 Plan generally have a
term of ten years.
 
    In the event of a change of control of the Company, including a liquidation,
merger  or sale  of substantially all  of the Company's  assets, all outstanding
options will be  assumed or an  equivalent option substituted  by the  successor
corporation  or its parent or subsidiary  unless the Administrator determines in
its sole discretion that each optionee shall  have the right to exercise his  or
her  option in  full, regardless  of vesting.  In the  absence of  assumption or
substitution, any options not exercised as of the date of the change of  control
shall terminate upon such change of control.
 
1996 EMPLOYEE STOCK PURCHASE PLAN
 
   
    The  Company has reserved an aggregate of 100,000 shares of Common Stock for
issuance under its 1996 Employee Stock Purchase Plan (the "ESPP"). The ESPP  was
adopted  by the Board of Directors and  approved by the stockholders in February
1996. The ESPP is intended to qualify under Section 423 of the Internal  Revenue
Code  of 1986, as  amended (the "Code"),  and permits eligible  employees of the
Company to purchase  Common Stock  through payroll deductions  of up  to 15%  of
their  compensation  (up to  30%  of their  compensation  for the  first period,
commencing on July 1,  1996 and ending  on December 31,  1996) provided that  no
employee may purchase more than $25,000 worth of stock in any calendar year. The
ESPP  has been implemented as a series of successive six-month offering periods,
the first of which  commenced on July 1,  1996 and will end  on the last  market
trading  day on or before December 31, 1996. The price of Common Stock purchased
under the ESPP will be 85% of the  lower of the fair market value of the  Common
Stock on the first and last day of each offering period. The ESPP will expire in
2006.
    
 
    As of August 31, 1996, no shares had been issued under the ESPP.
 
1996 DIRECTOR OPTION PLAN
 
    Non-employee  directors are  entitled to  participate in  the Company's 1996
Director Option Plan (the "Director Plan"). The Director Plan was adopted by the
Board of  Directors and  approved  by the  stockholders  in February  1996,  and
amended  by the Board of Directors in August  1996. A total of 100,000 shares of
Common Stock has been reserved for issuance under the Director Plan, options  to
purchase  5,000 of which were issued and  outstanding as of August 31, 1996. The
Director Plan provides that each non-employee director shall be granted, at  the
discretion of the Board of Directors,
 
                                       39
<PAGE>
   
a  nonstatutory option to  purchase shares of Common  Stock (the "First Option")
upon the date such non-employee director first becomes a director (other than an
employee director  who ceases  to be  an employee  but remains  a director).  In
addition,  each non-employee director  who has been  a non-employee director for
longer than six months will annually be granted, at the discretion of the  Board
of  Directors,  a nonstatutory  option  to purchase  shares  of Common  Stock (a
"Subsequent Option"). Each non-employee director  will be eligible to receive  a
Subsequent Option, regardless of whether such non-employee director was eligible
to  receive a First Option. Each First  Option and Subsequent Option will have a
term expiring on the earlier  of the tenth anniversary of  the date of grant  or
twelve  months  after the  date  on which  the optionee  ends  his service  as a
director. The vesting terms of both  the First Option and the Subsequent  Option
shall  be at the discretion  of the Board of Directors.  The exercise price of a
director option will be 100% of the fair market value per share of the Company's
Common Stock on the  date of the grant  of the option. The  exercise price of  a
director option granted to a director who owns more than 10% of the voting power
of  all classes of the  Company's outstanding capital stock  must be equal to at
least 110% of the fair market value of the Common Stock on the date of grant.
    
 
401(K) SAVINGS PLAN
 
   
    The Company maintains the IntelliQuest,  Inc. 401(k) Savings and  Retirement
Plan, a defined contribution retirement plan with a cash or deferred arrangement
as  described in Section 401(k) of the Code (the "401(k) Plan"). The 401(k) Plan
is intended to be qualified under Section  401(a) of the Code. All employees  of
the  Company are eligible to participate in the  401(k) Plan on the first day of
the month concurrent with or following the first anniversary of employment.  The
401(k)  Plan provides that each participant  make elective contributions from 1%
to 15% of his or her compensation, subject to statutory limits. The Company also
provides a  discretionary  100%  matching  contribution,  subject  to  statutory
limits.  Under  the  terms  of  the  401(k)  Plan,  allocation  of  the matching
contribution is integrated with Social  Security, in accordance with  applicable
nondiscrimination rules under the Code.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 30,000,000 shares of
Common  Stock, $.0001 par value, and 1,000,000 shares of Preferred Stock, $.0001
par value.
 
    The following  summary  of  certain  provisions  of  the  Common  Stock  and
Preferred Stock does not purport to be complete and is subject to, and qualified
in its entirety by, the provisions of the Company's Certificate of Incorporation
which  is included  as an  exhibit to the  Registration Statement  of which this
Prospectus is a part and by the provisions of applicable law.
 
COMMON STOCK
 
    There will  be 8,068,708  shares of  Common Stock  outstanding (assuming  no
exercise  after August 31,  1996 of outstanding options)  after giving effect to
the sale of Common Stock offered hereby.
 
    The holders of Common Stock are entitled to one vote for each share held  of
record  on  all  matters  submitted  to  a  vote  of  stockholders.  Subject  to
preferences that may be applicable to any outstanding shares of Preferred Stock,
the holders of Common Stock are  entitled to receive ratably such dividends,  if
any, as may be declared by the Board of Directors out of funds legally available
for  the  payment  of  dividends.  See "Dividend  Policy."  In  the  event  of a
liquidation, dissolution or  winding up of  the Company, the  holders of  Common
Stock  are entitled to  share ratably in  all assets remaining  after payment of
liabilities and liquidation preferences of  any outstanding shares of  Preferred
Stock.  Holders of Common Stock  have no preemptive rights  or rights to convert
their Common Stock into any other securities. There are no redemption or sinking
fund provisions applicable to the Common Stock. All outstanding shares of Common
Stock are fully paid and  non-assessable, and the shares  of Common Stock to  be
issued upon completion of this offering will be fully paid and non-assessable.
 
PREFERRED STOCK
 
    Pursuant  to  the  Company's  Certificate  of  Incorporation,  the  Board of
Directors has  the authority,  without further  action by  the stockholders,  to
issue up to 1,000,000 shares of Preferred Stock in one or more series and to fix
the  designations, powers, preferences,  privileges, and relative participating,
optional or special rights and  the qualifications, limitations or  restrictions
thereof,  including dividend rights, conversion  rights, voting rights, terms of
redemption and liquidation preferences, any or all of which may be greater  than
the  rights of  the Common  Stock. The  Board of  Directors, without stockholder
approval, can issue Preferred Stock with voting, conversion or other rights that
could adversely  affect the  voting power  and other  rights of  the holders  of
Common Stock. Preferred Stock could thus be issued quickly with terms calculated
to  delay or  prevent a  change in  control of  the Company  or make  removal of
management more difficult.  Additionally, the  issuance of  Preferred Stock  may
have  the effect  of decreasing the  market price  of the Common  Stock, and may
adversely affect the voting and other rights of the holders of Common Stock.  At
present,  there are no shares of Preferred Stock outstanding and the Company has
no plans to issue any of the Preferred Stock.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS
AND DELAWARE LAW
 
CERTIFICATE OF INCORPORATION AND BYLAWS
 
    The Certificate of Incorporation provides that all stockholder actions  must
be effected at a duly called meeting and not by a consent in writing. The Bylaws
provide   that  the  Company's  stockholders  may  call  a  special  meeting  of
stockholders only upon  a request  of stockholders owning  at least  50% of  the
Company's  capital stock. These  provisions of the  Certificate of Incorporation
and Bylaws could discourage potential  acquisition proposals and could delay  or
prevent  a change in  control of the  Company. These provisions  are intended to
enhance the likelihood  of continuity and  stability in the  composition of  the
Board  of Directors and in the policies formulated by the Board of Directors and
to discourage  certain types  of  transactions that  may  involve an  actual  or
threatened  change of control  of the Company. These  provisions are designed to
reduce the vulnerability of the Company to an unsolicited acquisition  proposal.
The  provisions also are intended to discourage certain tactics that may be used
in proxy fights. However, such provisions could have the effect of  discouraging
others
 
                                       43

from  making tender offers for the Company's  shares and, as a consequence, they
also may inhibit  increases in  the market price  of the  Company's shares  that
could  result from actual or rumored takeover attempts. Such provisions also may
have the effect  of preventing  changes in the  management of  the Company.  See
"Risk Factors -- Effect of Anti-Takeover Provisions."
 
DELAWARE TAKEOVER STATUTE
 
    The  Company is subject  to Section 203 of  the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a  Delaware
corporation  from  engaging  in  any business  combination  with  any interested
stockholder for a period of three years following the date that such stockholder
became an interested stockholder, unless: (i)  prior to such date, the Board  of
Directors  of the  corporation approved either  the business  combination or the
transaction that resulted in the stockholder becoming an interested stockholder;
(ii) upon  consummation of  the  transaction that  resulted in  the  stockholder
becoming  an interested stockholder,  the interested stockholder  owned at least
85% of  the  voting  stock  of  the corporation  outstanding  at  the  time  the
transaction  commenced,  excluding for  purposes  of determining  the  number of
shares outstanding those shares owned (x) by persons who are directors and  also
officers  and (y) by employee stock plans  in which employee participants do not
have the right to  determine confidentially whether shares  held subject to  the
plan  will be tendered in a tender or  exchange offer; or (iii) on or subsequent
to such date, the business combination is approved by the Board of Directors and
authorized at an annual or special  meeting of stockholders, and not by  written
consent,  by the affirmative vote of at  least 66 2/3% of the outstanding voting
stock that is not owned by the interested stockholder.
 
    Section 203  defines business  combination  to include:  (i) any  merger  or
consolidation involving the corporation and the interested stockholder; (ii) any
sale,  transfer, pledge or other disposition of 10% or more of the assets of the
corporation involving  the  interested  stockholder; (iii)  subject  to  certain
exceptions,  any transaction  that results  in the  issuance or  transfer by the
corporation of any stock of the corporation to the interested stockholder;  (iv)
any  transaction involving the corporation that has the effect of increasing the
proportionate share  of the  stock of  any class  or series  of the  corporation
beneficially  owned by  the interested stockholder;  and (v) the  receipt by the
interested stockholder  of  the  benefit of  any  loans,  advances,  guarantees,
pledges  or other financial benefits provided  by or through the corporation. In
general, Section 203 defines  an interested stockholder as  an entity or  person
beneficially  owning  15%  or  more  of  the  outstanding  voting  stock  of the
corporation  and  any  entity  or  person  affiliated  with  or  controlling  or
controlled by such entity or person.
 
REGISTRATION RIGHTS
 
    After this offering, the holders of approximately 1,000,686 shares of Common
Stock  will be entitled  to certain rights  with respect to  the registration of
such shares under the Securities Act.
 
   
    With respect  to approximately  741,218  of such  shares, these  rights  are
provided  under the terms of an agreement between the Company and the holders of
certain shares of capital stock that have been converted into Common Stock  (the
"Registrable Securities"). Subject to certain limitations in such agreement, the
holders  of  at least  50% of  the Registrable  Securities then  outstanding may
require, on no more than two occasions, that the Company use its best efforts to
register the Registrable  Securities for public  resale, provided the  estimated
aggregate  offering price of such securities  exceeds $5,000,000. If the Company
registers any of its Common Stock either for its own account or for the  account
of other security holders on Form S-3, the holders of Registrable Securities are
entitled to include their shares of Common Stock in the registration. A holder's
right  to  include shares  in  an underwritten  registration  is subject  to the
ability of  the underwriters  to limit  the number  of shares  included in  such
offering. The holders of Registrable Securities may also require the Company, on
no more than two occasions over 12 months, to register all or a portion of their
Registrable  Securities on Form S-3  when use of such  form becomes available to
the Company,  provided, among  other limitations,  that the  proposed  aggregate
selling  price, net of  the underwriting discounts and  commissions, is at least
$500,000. All registration and selling expenses attributable to the registration
of  the  holders'  shares  must  be   borne  by  the  holders  requesting   such
registration.
    
 
                                       44
<PAGE>
    With  respect  to approximately  259,468 of  such  shares, these  rights are
provided under the terms of a registration rights agreement between the Company,
holders of the shares  of Common Stock described  in the previous paragraph  and
certain  former shareholders of IntelliQuest  Communications. Subject to certain
limitations in such agreement, the holders of such shares may register up to 50%
of their shares in a  registration initiated by the  Company either for its  own
account  or for the account  of other security holders.  After December 1, 1997,
the holders of at least 40% of such securities then outstanding may require that
the Company  use  its  best  efforts  to  register  all  shares  held  by  those
stockholders requesting such registration. All registration and selling expenses
attributable  to the registration  of the holders'  shares will be  borne by the
Company.
 
TRANSFER AGENT AND REGISTRAR
 
   
    The transfer agent and registrar for the Company's Common Stock is  American
Securities Transfer and Trust, Incorporated.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon  completion  of this  offering, the  Company  will have  outstanding an
aggregate  of  8,068,708  shares  of  Common  Stock,  assuming  no  exercise  of
outstanding options after August 31, 1996. Of these outstanding shares of Common
Stock,  the 2,881,000 shares  sold in this  offering and approximately 2,676,337
additional  shares  already  outstanding   will  be  freely  tradeable   without
restriction  or further registration under  the Securities Act, unless purchased
by "affiliates" of the  Company as that  term is defined in  Rule 144 under  the
Securities  Act. The remaining 2,511,371 shares of Common Stock held by existing
stockholders are "restricted  securities" as that  term is defined  in Rule  144
under  the  Securities Act  ("Restricted  Shares") and  will  be subject  to the
lock-up arrangements  described below.  Restricted  Shares may  be sold  in  the
public  market  only if  registered or  if  they qualify  for an  exemption from
registration under Rules  144, 144(k)  or 701 promulgated  under the  Securities
Act,  which are summarized below.  Sales of the Restricted  Shares in the public
market, or the availability of such shares for sale, could adversely affect  the
market price of the Common Stock.
    
 
    The   Company  and  its  directors,   executive  officers  and  all  Selling
Stockholders have entered into  contractual "lock-up" agreements providing  that
they  will not offer, sell, contract to sell  or grant any option to purchase or
otherwise dispose of the shares of Common  Stock owned by them or that could  be
purchased  by them through the  exercise of options to  purchase Common Stock of
the Company for a period  of 90 days after the  date of this Prospectus  without
the  prior written  consent of William  Blair &  Company, L.L.C. As  a result of
these contractual restrictions, notwithstanding possible earlier eligibility for
sale under the provisions of  Rules 144, 144(k) and  701, the shares subject  to
lock-up  agreements will not  be saleable until  90 days after  the date of this
Prospectus (or earlier with the consent of William Blair & Company, L.L.C.).
 
    In general, under  Rule 144  as currently in  effect, a  person (or  persons
whose shares are aggregated) who has beneficially owned Restricted Shares for at
least  two years  (including the  holding period  of any  prior owner  except an
affiliate of  the Company)  would be  entitled to  sell within  any  three-month
period  a number of shares that does not  exceed the greater of: (i) one percent
of the  number of  shares of  Common Stock  then outstanding  (which will  equal
approximately  80,687  shares  immediately  after this  offering);  or  (ii) the
average weekly trading volume of the Common Stock during the four calendar weeks
preceding the filing of a Form 144  with respect to such sale. Sales under  Rule
144   are  also  subject  to  certain  manner  of  sale  provisions  and  notice
requirements and to  the availability  of current public  information about  the
Company. Under Rule 144(k), a person who is not deemed to have been an affiliate
of  the Company at  any time during  the 90 days  preceding a sale,  and who has
beneficially owned  the shares  proposed to  be sold  for at  least three  years
(including  the holding  period of  any prior owner  except an  affiliate of the
Company), is entitled to sell such  shares without complying with the manner  of
sale,  public information, volume  limitation or notice  provisions of Rule 144;
therefore, unless otherwise restricted, "144(k) shares" may be sold  immediately
upon the completion of this offering.
 
    Any  employee,  officer or  director  of or  consultant  to the  Company who
purchased his or her shares pursuant to a written compensatory plan or  contract
may  be entitled to rely on the resale  provisions of Rule 701. Rule 701 permits
affiliates of the Company to sell their  Rule 701 shares under Rule 144  without
complying  with the  holding period requirements  of Rule 144.  Rule 701 further
provides that  non-affiliates may  sell  such shares  in  reliance on  Rule  144
without  having  to comply  with the  public  information, volume  limitation or
notice provisions of Rule 144. The Company has filed a registration statement on
Form S-8 under  the Securities Act  covering an aggregate  of 741,080 shares  of
Common  Stock reserved for  issuance under the Company's  1993 Option Plan, 1996
Plan, the  Director Plan  and  the ESPP.  See  "Management --  Employee  Benefit
Plans."  Shares registered  under such  registration statement  will, subject to
Rule 144  volume  limitations  applicable  to  affiliates  of  the  Company,  be
available for sale in the open market, unless such shares are subject to vesting
restrictions  with the Company or the  lock-up agreements described above. As of
August 31, 1996 options to purchase  135,500 shares were issued and  outstanding
under  the 1993 Option Plan, options to purchase 168,094 shares had been granted
under the 1996 Plan, options to purchase 5,000 shares had been granted under the
Director Plan and no shares had been issued under the ESPP.

    In  the Underwriting Agreement, the Underwriters have agreed, subject to the
terms and conditions  set forth  therein, to purchase  all of  the Common  Stock
being  sold pursuant to  the Underwriting Agreement  if any of  the Common Stock
being sold pursuant to the  Underwriting Agreement (excluding shares covered  by
the  over-allotment  option granted  therein) is  purchased. In  the event  of a
default by any Underwriter, the Underwriting Agreement provides that, in certain
circumstances, purchase commitments of the non-defaulting Underwriters shall  be
increased or the Underwriting Agreement may be terminated.
 
    The  Representatives have advised  the Company and  the Selling Stockholders
that the Underwriters propose to offer the Common Stock to the public  initially
at  the public offering price set forth on the cover page of this Prospectus and
to selected dealers at  such price less a  concession of not more  than $    per
share.  The Underwriters may allow, and  such dealers may re-allow, a concession
not in excess  of $     per share  to certain  other dealers.  After the  public
offering,  the public offering price  and other selling terms  may be changed by
the Representatives.
 
    Certain Selling Stockholders  have granted  to the  Underwriters an  option,
exercisable  within 30 days after the date of this Prospectus, to purchase up to
an additional 432,150 shares of Common Stock  at the same price per share to  be
paid   by  the  Underwriters  for  the  other  shares  offered  hereby.  If  the
Underwriters purchase any such additional  shares pursuant to this option,  each
of  the Underwriters  will be  committed to  purchase such  additional shares in
approximately the  same  proportion  as  set  forth  in  the  table  above.  The
Underwriters   may  exercise  the  option  only  for  the  purpose  of  covering
over-allotments, if any, made in connection with the distribution of the  Common
Stock  offered hereby. The  additional shares purchased  pursuant to this option
shall be  allocated among  Austin Ventures,  L.P., Summit  Ventures, L.P,  Peter
Zandan, Brian Sharples and James Schellhase.
 
    The  Company, its directors, executive officers and all Selling Stockholders
have agreed that they will  not sell, contract to  sell or otherwise dispose  of
any  Common Stock or any interest therein for a period of 90 days after the date
of this Prospectus without the prior written consent of William Blair & Company,
L.L.C., except for the Common Stock offered hereby.
 
    The Company  and  the Selling  Stockholders  have agreed  to  indemnify  the
Underwriters   and  their  controlling   persons  against  certain  liabilities,
including liabilities under the Securities Act, or to contribute to payments the
Underwriters may be required to make in respect thereof.
 
    The rules of the  Commission generally prohibit  the Underwriters and  other
members  of the  selling group, if  any, from  making a market  in the Company's
Common  Stock  during  the   "cooling-off"  period  immediately  preceding   the
commencement  of sales  in the  offering. The  Commission has,  however, adopted
exemptions from  these rules  that permit  passive market  making under  certain
conditions.  These rules permit  an underwriter or other  members of the selling
group, if any, to
 
                                       47
<PAGE>
continue to make a market subject to the conditions, among others, that its  bid
not exceed the highest bid by a market maker not connected with the offering and
that  its net  purchases on  any one trading  day not  exceed prescribed limits.
Pursuant to  these exemptions,  certain Underwriters  and other  members of  the
selling  group, if  any, may  engage in passive  market making  in the Company's
Common Stock during the cooling-off period.
 
                                 LEGAL MATTERS
 
    Certain legal matters with  respect to the legality  of the issuance of  the

In  our opinion,  the accompanying  consolidated balance  sheet and  the related
consolidated statements of operations, of common stockholders' equity  (deficit)
and  of  cash flows  present  fairly, in  all  material respects,  the financial
position of  IntelliQuest  Information  Group,  Inc.  and  its  subsidiaries  at
December  31, 1995 and 1994  and the results of  their operations and their cash
flows for each  of the three  years in the  period ended December  31, 1995,  in
conformity  with  generally  accepted  accounting  principles.  These  financial
statements  are   the   responsibility   of  the   Company's   management;   our
responsibility  is to express an opinion  on these financial statements based on
our audits.  We conducted  our audits  of these  statements in  accordance  with
generally accepted auditing standards which require that we plan and perform the
audit  to obtain reasonable assurance about whether the financial statements are
free of material  misstatement. An audit  includes examining, on  a test  basis,
evidence  supporting the  amounts and  disclosures in  the financial statements,
assessing the  accounting  principles used  and  significant estimates  made  by
management,  and  evaluating the  overall  financial statement  presentation. We
believe that our  audits provide a  reasonable basis for  the opinion  expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  THE COMPANY
   
    IntelliQuest  Information Group, Inc. ("IntelliQuest" or the "Company") is a
leading provider of quantitative marketing information to technology  companies.
IntelliQuest   supplies   customers   with  timely,   objective,   accurate  and
cost-effective information about technology  markets, customers and products  on
both  a subscription basis and a proprietary project basis. The Company operates
in a single industry segment.
    
 
    IntelliQuest, Inc. ("Old IntelliQuest") was  incorporated in Texas in  1985.
In  1993, Old IntelliQuest was acquired by IntelliQuest, a majority of which was
owned by the former  principal of Old IntelliQuest.  In connection with this,  a
cash  payment  of $2,050,000  was  made to  the  controlling shareholder  of Old
IntelliQuest. This acquisition was accounted for as a reorganization of entities
under common control, where the bases of Old IntelliQuest assets and liabilities
carried over to  IntelliQuest. IntelliQuest  was reincorporated  in Delaware  on
March  19, 1996. In  conjunction with this  reincorporation, the Company changed
its name to IntelliQuest Information Group, Inc.
 
    During 1995, the Company formed a wholly-owned subsidiary located in London,
England. At  December  31,  1995,  the total  assets  and  liabilities  of  this
subsidiary  were  approximately  $259,000  and  $42,000,  respectively,  net  of
intercompany eliminations. Net losses  related to this  subsidiary for the  year
ended December 31, 1995 totaled $34,000. In addition, as more fully described in
Note  2,  IntelliQuest  acquired IntelliQuest  Communications  during  May 1996.
Unless otherwise specified, references herein to the "Company" or "IntelliQuest"
mean  IntelliQuest  Information  Group,  Inc.   and  all  of  its   wholly-owned
subsidiaries.
 
    THE DELAWARE REINCORPORATION
 
    In  connection with the  reincorporation, IntelliQuest exchanged  1 share of
its preferred stock and common stock  for every 1.364 shares of preferred  stock
and  common stock,  respectively, held by  the stockholders  of Old IntelliQuest
(the "Share Exchange"). All shares and per share amounts, including warrants and
options for such shares, included in the accompanying financial statements  have
been  adjusted to give  retroactive effect to  the Share Exchange. Additionally,
IntelliQuest's Certificate of Incorporation, amended following the  consummation
of  the initial  public offering, authorized  30,000,000 shares  of Common Stock
with a $.0001 par value  and 1,000,000 shares of  preferred stock with a  $.0001
par value. The Board of Directors has the authority to issue the preferred stock
and to fix the rights, preferences, privileges and restrictions thereof, without
further vote or action by the stockholders.
 
2.  ACQUISITION
    In   May   1996,   IntelliQuest  completed   a   merger   with  IntelliQuest
Communications, Inc. ("IntelliQuest Communications," formerly known as  Pipeline
Communications, Inc.), which became a wholly-owned subsidiary of IntelliQuest. A
total  of 562,500 shares  of IntelliQuest common stock  and common stock options
were exchanged for all  outstanding shares of common  stock, stock options,  and
warrants  of IntelliQuest Communications. The transaction was accounted for as a
pooling of interests and therefore,  all prior period financial statements  have
been  restated as if  the acquisition had  taken place at  the beginning of such
periods.

3.  SIGNIFICANT ACCOUNTING POLICIES
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported amounts  of  assets and  liabilities and
disclosure of contingent  assets and liabilities  at the date  of the  financial
statements  and  the  reported  amounts  of  revenues  and  expenses  during the
reporting period. Since much of the Company's revenues are based upon percentage
of projects completed based on costs  input compared to total estimated  project
costs,  the determination of the resultant revenue requires ongoing estimates by
management of costs to complete these projects. Actual results could differ from
those estimates.
 
    The accompanying consolidated  balance sheet  as of  June 30,  1996 and  the
related  consolidated statements  of operations, of  common stockholders' equity
(deficit) and of cash flows for the six months ended June 30, 1995 and 1996  are
unaudited  but, in the opinion of management include all adjustments (consisting
of normal, recurring adjustments) necessary  for a fair presentation of  results
for these interim periods.
 
    REVENUE RECOGNITION
 
    The  Company  offers  renewable  subscription-based  products  which provide
similar information to a number of  clients at a shared-cost price. The  Company
also  offers proprietary tracking  products that manage  ongoing market feedback
and  proprietary  research.  Revenue  from  certain  annual   subscription-based
products  (such as Computer  Industry Media Study (CIMS))  and the related costs
are deferred until  delivery. Revenues from  other renewable  subscription-based
and   proprietary  tracking  products  containing   a  subscription  period  are
recognized on a straight-line basis over the subscription period. Revenues  from
processing  transactions are  recognized as  the transactions  are processed for
customers and are included in renewable proprietary products revenues.  Revenues
from  proprietary  research service  contracts are  recognized in  proportion to
performance required under  the contracts  (percentage of  completion) based  on
cost input. Losses on a given contract are recognized when determined probable.
 
    The  Company bills its clients  for products and services  based on terms of
the contracts,  which  may  not  coincide with  criteria  required  for  revenue
recognition. Deferred revenue represents amounts

3.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
invoiced  prior  to  rendering  the  related  services  while  unbilled  revenue
represents the  billing value  of  services rendered  prior to  being  invoiced.
Substantially  all the deferred and unbilled  revenue will be earned and billed,
respectively, within twelve months of the respective period ends.
 
    PRODUCT DEVELOPMENT COSTS
 
    Product development costs include  costs incurred to  develop or design  new
products,  services or  processes and  significantly enhance  existing products,
services and  processes and  are expensed  as incurred.  If material,  costs  to
develop  software, which is an  integral part of a  product or service, that are
incurred subsequent to  attaining technological feasibility  are capitalized  in
accordance with Statement of Financial Accounting Standards (SFAS) No. 86. These
costs  are then amortized on  a straight line basis  over the estimated economic
life or on the  ratio of current revenues  to total projected product  revenues,
whichever   is  greater.  To  date,   costs  incurred  subsequent  to  attaining
technological feasibility have been immaterial and therefore the Company has not
capitalized any such costs.
 
    REDEEMABLE CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY
 
    Redeemable convertible preferred  stock is presented  net of issuance  costs
and  approximates  redemption value.  As  discussed in  Note  9, all  holders of
redeemable convertible preferred  stock converted  their redeemable  convertible
preferred  stock into common stock concurrent with the closing of IntelliQuest's
initial public offering. The redeemable convertible preferred stockholders  also
received warrants to purchase 264,480 shares of Common Stock at $2.03 per share.
These warrants were exercised prior to the initial public offering.
 
    PRO FORMA NET INCOME PER SHARE
 
    The  Company's  historical  capital  structure  is  not  indicative  of  its
prospective structure  due  to  the  conversion  of  all  shares  of  redeemable
convertible  preferred stock into  common stock and the  exercise of warrants to
purchase common  stock concurrent  with  the closing  of the  Company's  initial
public  offering. Accordingly,  historical net  income (loss)  per share  is not
considered meaningful and has not been presented herein.
 
    Pro forma net income per share  is computed based upon the weighted  average
number  of common  shares outstanding  and gives  effect to  certain adjustments
described below. Common  equivalent shares  are not  included in  the per  share
calculations  where the effect of their  inclusion would be antidilutive, except
that,  for  1995   in  conformity   with  Securties   and  Exchange   Commission
requirements,  common and common  stock equivalent shares  issued by the Company
during the  twelve  month period  prior  to the  filing  of its  initial  public
offering  have been included in the calculation  as if they were outstanding for
all periods, using  the treasury stock  method and the  initial public  offering
price of $17 per share. Additionally, 1,055,718 shares of redeemable convertible
preferred  stock  designated as  the Series  A  Convertible Preferred  Stock and
797,328 shares  of  redeemable convertible  preferred  stock designated  as  the
Series  B Convertible  Preferred Stock were  assumed to have  been converted and
warrants to purchase 264,480  shares of Common Stock  were assumed to have  been
exercised  as of January 1, 1995. The redeemable convertible preferred stock was
converted and  the warrants  were  exercised in  connection with  the  Company's
initial public offering in March 1996.
 
    FURNITURE AND EQUIPMENT
 
    Furniture  and equipment is stated at  cost, net of accumulated depreciation
and amortization. Depreciation and amortization  is provided on a  straight-line
basis  over the estimated useful lives of the respective assets which range from
three to seven years.  Amortization of assets acquired  under capital leases  is
included in depreciation and amortization.

3.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    PROJECT COSTS
 
    Costs  associated with CIMS are deferred and included in projects in process
until the results of the study are delivered. These costs include personnel  and
other  direct costs, as well as associated  overhead. Upon release of the study,
these costs are included in cost of revenues.
 
    Costs relating to  all other projects,  including development of  databases,
are expensed as incurred.
 
    INCOME TAXES
 
    Deferred  income  taxes  are provided  for  the tax  effects  of differences
between the financial reporting bases and the income tax bases of the  Company's
assets and liabilities as measured by the enacted tax rates.
 
    CASH EQUIVALENTS AND INVESTMENTS
 
    The Company considers all highly liquid investments with original maturities
of less than three months to be cash equivalents.
 
    Included  in cash  and equivalents  are investments  consisting primarily of
U.S. government debt securities with readily determinable fair market values. In
accordance with Statement of Financial Accounting Standards No. 115, "Accounting
for  Certain  Investments  in  Debt   and  Equity  Securities,"  the   Company's
investments  are classified as available-for-sale  and accordingly, are reported
at fair value,  with unrealized  gains and  losses reported  net of  taxes as  a
separate component of common stockholders' equity.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The  carrying  amount of  cash,  accounts receivable,  accounts  payable and
accrued liabilities is a reasonable estimate of their fair value because of  the
short-term maturity of all such instruments.
 
    FOREIGN CURRENCIES
 
    The  foreign subsidiary  operates in  a local  currency environment. Balance
sheet accounts are translated  at exchange rates existing  at the balance  sheet
date.  Revenue and  expense accounts  are translated  at average  exchange rates
prevailing during the period. Translation  gains and losses are accumulated  and
reported  as a separate  component of stockholders' equity.  There have not been
material translation gains or losses as of December 31, 1995.
 
    NEW ACCOUNTING PRONOUNCEMENTS
 
    The Financial Accounting Standards Board  has issued Statement of  Financial
Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived Assets
and  for Long-Lived Assets to be Disposed Of." The Company adopted the statement
in the first quarter of 1996 and the adoption did not have a material effect.
 
    The Financial  Accounting  Standards  Board  recently  issued  Statement  of
Financial  Accounting Standards No. 123, Accounting for Stock-Based Compensation
(FAS No. 123). FAS No. 123 establishes  a fair value based method of  accounting
for  stock-based compensation plans. It also allows for companies to continue to
follow the  intrinsic  value based  approach  previously allowed  with  footnote
disclosure  of the pro forma net income and earnings per share of the fair value
based approach. The Company  anticipates following this  latter approach so  the
impact on the Company's financial statements will not be significant.

from IntelliQuest  Communications, a  wholly-owned  subsidiary of  the  Company.
These  assets  include  net  operating  loss  carryforwards,  and  research  and
experimentation credit carryforwards.  These carryforwards may  only be used  to
offset  tax liabilities generated by IntelliQuest Communications. Because of the
uncertainties with respect to  IntelliQuest Communications' ability to  generate
sufficient  future  taxable  income to  realize  these assets,  the  Company has
provided a valuation allowance against  all of IntelliQuest Communications'  net
deferred tax assets.
 
    As  of December 31, 1995, IntelliQuest Communications has net operating loss
and research and  experimentation credit  carryforwards for  Federal income  tax
purposes   of   approximately   $934,000   and   $34,000,   respectively.  These
carryforwards expire beginning 2008 through 2010.

10. STOCK OPTIONS
 
    1993 STOCK PLAN
 
    A  total of 344,256 shares  of the Company's Series  B Common Stock has been
authorized  for  issuance.   Under  the   Plan,  incentive   stock  options   or
non-qualified  stock options  may be granted  with exercise  prices equaling the
fair market  value of  the stock  at the  time of  grant, as  determined by  the
Company's  Board of Directors unless  the optionee owns greater  than 10% of the
voting power of all  classes of stock,  in which case the  option price will  be
110%  of the  fair value at  the date  of grant, as  determined by  the Board of
Directors. Options granted  under the plan  generally have a  term of ten  years
from  the date of grant and generally vest over a five-year period. If an option
expires or becomes unexercisable for any reason, options related to the unissued
shares become available for grant.

    Options  canceled  represent the  unexercised  options of  former employees,
returned to the option  pool in accordance  with the terms  of the stock  option
plan,  upon their departure from the  Company. In connection with options issued
during 1995, the  Company is recognizing  compensation expense totaling  $68,000
over the vesting period.
 
    OTHER STOCK OPTION GRANTS
 
    IntelliQuest Communications had previously issued stock options and warrants
to  non-employees. IntelliQuest Communications' options and warrants outstanding
as of December 31, 1995 were converted into options to purchase 16,408 shares of
IntelliQuest common stock upon the acquisition of IntelliQuest Communications.
 
    REPURCHASE OF OPTIONS
 
    During 1992, prior  to formation  of IntelliQuest,  Old IntelliQuest  issued
stock  options to  an officer  to purchase  43,235 shares  of Common  Stock at a
purchase price based upon the fair value of the Company as of the date of  grant
as  adjusted  for certain  dividends  paid between  the  date of  grant  and the
exercise date. These options were accounted for as variable options. The options
were repurchased  by  IntelliQuest in  conjunction  with the  formation  of  the
Company  for their estimated  fair value of  $250,000 and canceled. Compensation
expense was  recognized  in  1993  for the  difference  ($200,000)  between  the
compensation recorded in 1992 ($50,000) and the purchase price of the options.
 
11. EMPLOYEES' SAVINGS PLAN
    The  Company's 401(k) Savings and Retirement  Plan is a defined contribution
retirement plan with  a cash  or deferred  arrangement as  described in  Section
401(k)  of  the Code  (the "401(k)  Plan"). The  401(k) Plan  is intended  to be
qualified under Section  401(a) of the  Code. All employees  of the Company  are
eligible  to  participate in  the 401(k)  Plan after  approximately one  year of
employment. The  401(k)  Plan  provides  that  each  participant  make  elective
contributions  from 1% to 15%  of his or her  compensation, subject to statutory
limits. Under  the  terms  of  the  401(k)  Plan,  allocation  of  the  matching
contribution  is integrated with Social  Security, in accordance with applicable
nondiscrimination rules under the Code. The Company made matching  contributions
in the amount of $11,000 in 1993, $5,000 in 1994 and $30,000 in 1995.

such  as  foreign  exchange  contracts,  options  contracts  or  other   hedging
agreements.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    As  permitted by  Section 145 of  the Delaware General  Corporation Law, the
Registrant's Certificate of Incorporation includes  a provision that limits  the
personal  liability of its directors for  monetary damages for breach or alleged
breach of their fiduciary  duties. In addition, as  permitted by Section 145  of
the Delaware General Corporation Law, the Bylaws of the Registrant provide that:
(i) the Registrant is required to indemnify its directors and executive officers
and persons serving in such capacities in other business enterprises (including,
for example, subsidiaries of the Registrant) at the Registrant's request, to the
fullest  extent permitted by  Delaware law, including  in those circumstances in
which indemnification would otherwise be discretionary; (ii) the Registrant may,
in its discretion, indemnify employees  and agents in those circumstances  where
indemnification  is not  required by  law; (iii)  the Registrant  is required to
advance expenses,  as  incurred, to  its  directors and  executive  officers  in
connection  with  defending a  proceeding  (except that  it  is not  required to
advance expenses to  a person against  whom the Registrant  brings a claim)  for
breach  of  the duty  of  loyalty, failure  to  act in  good  faith, intentional
misconduct, knowing violation of law  or deriving an improper personal  benefit;
(iv) the rights conferred in the Bylaws are not exclusive, and the Registrant is
authorized   to  enter  into  indemnification  agreements  with  its  directors,
executive officers and employees; and  (v) the Registrant may not  retroactively
amend  the  Bylaw provisions  in a  way that  adversely affects  such directors,
executive officers and employees.
 
    The Registrant's policy  is to  enter into  indemnification agreements  with
each  of its directors and executive officers that provide the maximum indemnity
allowed to  directors and  executive officers  by Section  145 of  the  Delaware
General Corporation Law and the Bylaws, as well as certain additional procedural
protections.  In addition, the  indemnity agreements provide  that directors and
executive officers  will  be indemnified  to  the fullest  possible  extent  not
prohibited   by  law  against  all  expenses  (including  attorney's  fees)  and
settlement amounts  paid  or incurred  by  them  in any  action  or  proceeding,
including any derivative action by or in the right of the Registrant, on account
of  their services as  directors or executive  officers of the  Registrant or as
directors or officers of any other  company or enterprise when they are  serving
in  such capacities at the request of the Registrant. The Registrant will not be
obligated pursuant to the indemnity agreements to indemnify or advance  expenses
to  an indemnified party with respect to  proceedings or claims initiated by the
indemnified party and not by way of defense, except with respect to  proceedings
specifically  authorized by the Board of Directors or brought to enforce a right
to   indemnification   under   the   indemnity   agreement,   the   Registrant's
 
                                      II-1
<PAGE>
Bylaws  or  any statute  or law.  Under  the agreements,  the Registrant  is not
obligated to indemnify the  indemnified party (i) for  any expenses incurred  by
the  indemnified  party  with  respect  to  any  proceeding  instituted  by  the
indemnified party to enforce or interpret the agreement, if a court of competent
jurisdiction determines  that  each  of  the material  assertions  made  by  the
indemnified  party  in  such  proceeding  was not  made  in  good  faith  or was
frivolous; (ii) for any  amounts paid in settlement  of a proceeding unless  the
Registrant  consents to  such settlement; (iii)  with respect  to any proceeding
brought by the Registrant against the indemnified party for willful  misconduct,
unless a court determines that each of such claims was not made in good faith or
was frivolous; (iv) on account of any suit in which judgment is rendered against
the  indemnified party for  an accounting of  profits made from  the purchase or
sale by the indemnified  party of securities of  the Registrant pursuant to  the
provisions  of Section 16(b) of the Securities  Exchange Act of 1934 and related
laws; (v)  on  account of  the  indemnified  party's conduct  which  is  finally
adjudged  to have  been knowingly  fraudulent or  deliberately dishonest,  or to
constitute willful misconduct or a knowing violation of the law; (vi) on account
of any conduct  from which the  indemnified party derived  an improper  personal
benefit;  (vii)  on account  of  conduct the  indemnified  party believed  to be
contrary to the best interests of  the Registrant or its stockholders; (vii)  on
account  of conduct that constituted a breach of the indemnified party's duty of
loyalty to the Registrant or its stockholders; or (ix) if a final decision by  a
court   having   jurisdiction  in   the   matter  shall   determine   that  such
indemnification is not lawful.
 
   
    The  indemnification  provision  in  the  Bylaws  and  the   indemnification
agreements  entered into between the Registrant  and its directors and executive
officers,  may  be   sufficiently  broad  to   permit  indemnification  of   the
Registrant's officers and directors for liabilities arising under the Securities
Act of 1933, as amended (the "1933 Act").

to information about the Registrant.
 
    The issuance described in item 2  was deemed exempt from registration  under
the  1933  Act  in  reliance  upon  Regulation  D  promulgated  thereunder.  All

ITEM 17.  UNDERTAKINGS
 
    The  undersigned hereby  undertakes to  provide to  the Underwriters  at the
closing  specified  in   the  Underwriting  Agreement,   certificates  in   such
denominations  and registered in  such names as required  by the Underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as  indemnification for  liabilities arising  under the  Act may  be
permitted  to  directors, officers  and  controlling persons  of  the Registrant
pursuant to the provisions referenced in Item 14 of this Registration  Statement
or  otherwise,  the Registrant  has  been advised  that  in the  opinion  of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act, and is,  therefore, unenforceable. In the event that  a
claim  for indemnification against  such liabilities (other  than the payment by
the Registrant  of  expenses  incurred  or  paid  by  a  director,  officer,  or
controlling  person of the  Registrant in the successful  defense of any action,
suit or proceeding) is asserted by such director, officer or controlling  person
in  connection with  the securities  being registered  hereunder, the Registrant
will, unless  in the  opinion of  its counsel  the matter  has been  settled  by
controlling  precedent,  submit  to  a  court  of  appropriate  jurisdiction the
question whether  such  indemnification  by  it  is  against  public  policy  as
expressed  in the  Act and will  be governed  by the final  adjudication of such
issue.
 
    The undersigned Registrant hereby undertakes that:
 
        (1) For  purposes  of  determining  any liability  under  the  Act,  the
    information  omitted  from the  form  of Prospectus  filed  as part  of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    Prospectus filed by  the Registrant  pursuant to  Rule 424(b)(1)  or (4)  or
    497(h)  under  the Act  shall  be deemed  to  be part  of  this Registration
    Statement as of the time it was declared effective.
 
        (2) For the  purpose of determining  any liability under  the Act,  each
    post-effective  amendment that contains a form of Prospectus shall be deemed
    to be  a  new Registration  Statement  relating to  the  securities  offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
