BI firm Pentaho announced Quentin Gallivan has been appointed as its new CEO. Gallivan will be replacing founder Richard Daley, who is stepping down from his role  as the company’s head to become its Chief Strategy Officer. He will also remain active on Pentaho’s board.

“Quentin Gallivan came to our attention because of his proven ability to lead top-performing teams, his passion for the analytics market and his track record in driving shareholder value,” said Rob Bearden, Chairman of the Board.

Gallivan brings a lot of experience to the company. He served as the chief exec for Aster Data up until Teradata acquired it in April this year, and was also responsible for a lot of the growth Postini has seen, the email and web security firm that got acquired by Google in 07. Further, he also served at senior executive positions for GE and VeriSign, where he helped to grow revenues from $13 million to over a billion in the course of seven years.

This latest update from Pentaho follows a couple of other recent CEO-level staffing news. Joe Tucci, the CEO of storage giant EMC, said he will step down from his position at the end of 2011.  There’s still no word on who may be replacing him, but insider have brought up chief financial officer David Goulden, VCE president Frank Hauck and two other senior execs as potential candidates.

Shortly before Tucci’s statement, electronics maker Hewlett-Packard also had a similar yet somewhat more complex development. The company appointed former eBay head Meg Whitman as its third CEO in two years, not long after Leo Apotheker (who served as the chief exec of SAP) announced that his software strategy didn’t live up to expectations. HP pulled the plug on several webOS initiatives and will likely be spinning off its consumer electronics business.
