      I, Joseph J.  Caffarelli,  Chief Executive  Officer of CorVu  Corporation,
      certify that:

      1.    I have reviewed this report on Form 10-QSB of CorVu Corporation;

      2.    Based on my  knowledge,  this  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 report;

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

      4.    The small  business  issuer's  other  certifying  officer  and I are
            responsible for establishing and maintaining disclosure controls and
            procedures   (as  defined  in  Exchange  Act  Rules   13a-15(e)  and
            15d-15(e)) for the small business issuer and have:

            (a)Designed such disclosure controls and procedures,  or caused such
            disclosure   controls  and  procedures  to  be  designed  under  our
            supervision,  to ensure that  material  information  relating to the
            small business issuer, 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  small  business  issuer'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  small  business
            issuer's  internal  control over  financial  reporting that occurred
            during the small  business  issuer's most recent fiscal quarter (the
            small  business  issuer's  fourth  fiscal  quarter in the case of an
            annual report) that has materially affected, or is reasonably likely
            to materially  affect,  the small business issuer's internal control
            over financial reporting; and

      5.    The small  business  issuer's  other  certifying  officer and I have
            disclosed,  based on our most recent  evaluation of internal control
            over financial  reporting,  to the small business  issuer's auditors
            and the audit  committee  of the small  business  issuer'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 small business
            issuer'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 small  business
            issuer's internal control over financial reporting.
