Exhibit 31.2 Certification Pursuant to Rule 13a-14 of the Securities
Exchange Act of 1934

I, Karl Harz, certify that;

1.       I have reviewed this annual report on Form 10-KSB of Rocketinfo Inc.;

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