Court Square Sponsors Rocket Software

Court Square Capital Partners has quietly invested in Rocket Software, a Boston-area maker of enterprise infrastructure software. The deal was disclosed in a notice on the Federal Trade Commission website, indicating the it had received early termination of the Hart-Scott-Rodino waiting period.

This is Court Square’s first investment in Rocket, which was founded 19 years ago to developer and deliver software solutions to IBM mainframe customers deploying DB2 databse servers. Rocket soon licensed its IP to IBM, and had its products rebranded.

It has since expanded its licensing to other OEMs like Microsoft, and began making strategic acquisitions that resulted in Rocket selling over 100 different software products via its OEM partners, resellers and direct sales. Most recently, Rocket agreed to buy IBM’s U2 suite of “multivalue” database and application development products. That transaction also was disclosed in an FTC notice, although it does not say if the U2 and Court Square deals are related.

Court Square Capital was formed in 2006 by former members of Citigroup Venture Capital Equity Partners, including Bill Comfort. It is currently investing out of a $3.13 billion fund raised in 2006.

Rocket Software CEO Andy Youniss did not return our calls, while Court Square partner John Kim said that the firm typically does not comment on its transactions.
