About Us

Rocket Software was founded in 1990 with an initial focus on developing and delivering software solutions to IBM^® mainframe customers deploying IBM DB2^®. Within the first five years, Rocket licensed all of its intellectual property to IBM, and all of Rocket's products were rebranded and licensed to enterprises through IBM's worldwide sales channel.

Rocket Software purchased Mainstar Software Corporation in July of 2006. For over 30 years Rocket® Mainstar products have been focused on IBM System z software infrastructure and storage management with an emphasis on disaster recovery. We are dedicated to providing the software and services you need for serious results. That's why seven of the top ten Fortune 500 companies turn to Mainstar for System z products and expertise.
