Atomic PR has won a competitive pitch to handle global PR for open-source database software developer Ingres Corp.

Atomic is charged with handling “classical” PR, online and emerging media, and digital video services for Ingres, which has previously embraced social media like blogs and podcasts as part of its communications.

Tracy Eiler, senior VP of corporate marketing, said Atomic’s analysis of the open source database category “stood out from the other very good agencies that made our final list.” Budget was not disclosed.

Nick Olsson, VP at San Francisco-based Atomic, heads the account.

PE firm Garnett & Helfrich bought Ingres from Computer Associates in late 2005 and set up Ingres Corp. The company competes with database developers like Oracle and Sybase. Outcast PR had worked with Ingres in the past. The company continues to work with San Francisco-based Varney Business Communication.
