CERTIFICATION                       EXHIBIT 31
            Pursuant to Section 302 of the Sarbanes Oxley Act of 2002

I, Brian M. Overstreet, certify that:
       1.  I have reviewed this annual report on Form 10-KSB of Sagient Research
           Systems, Inc.;

       2.  Based on my knowledge, this annual report does not contain any untrue
           statement of a material fact or omit to state a material fact
           necessary to make the statements made, in light of the circumstances
           under which such statements were made, not misleading with respect to
           the period covered by this annual report;

       3.  Based on my knowledge, the financial statements, and other financial
           information included in this annual report, fairly present in all
           material respects the financial condition, results of operations and
           cash flows of the registrant as of, and for, the periods presented in
           this annual report;

       4.  I am responsible for establishing and maintaining disclosure controls
           and procedures (as defined in Exchange Act Rules 13a-15(e) and
           15d-15(e)) for the registrant and have:

           a) Designed such disclosure controls and procedures, or caused such
           disclosure controls and procedures to be designed under my
           supervision, to ensure that material information relating to the
           registrant, including its consolidated subsidiaries, is made known to
           us by others within those entities, particularly during the period in
           which this report is being prepared;

           b) Evaluated the effectiveness of the registrant's disclosure
           controls and procedures and presented in this report our conclusions
           about the effectiveness of the disclosure controls and procedures, as
           of the end of the period covered by this report based on such
           evaluation; and

           c) Disclosed in this report any change in the registrant's internal
           control over financial reporting that occurred during the
           registrant's most recent fiscal quarter (the registrant's fourth
           fiscal quarter in the case of an annual report) that has materially
           affected, or is reasonably likely to materially affect, the
           registrant's internal control over financial reporting; and

       5.  I have disclosed, based on our most recent evaluation of internal
           control over financial reporting, to the registrant's auditors and
           the audit committee of registrant's board of directors (or persons
           performing the equivalent functions):

           a) All significant deficiencies and material weaknesses in the design
           or operation of internal control over financial reporting which are
           reasonably likely to adversely affect the registrant's ability to
           record, process, summarize and report financial information; and

           b) Any fraud, whether or not material, that involves management or
           other employees who have a significant role in the registrant's
           internal control over financial reporting.
