Mobile advertising and publishing platform Tapjoy today announced it hired Jeff Drobick as Chief Product Officer. Drobick was formerly President and CEO of Geeknet Media and eBay Vice President of Information Management & Delivery.

“Jeff’s combination of bidded ad platform expertise and the proven delivery of data-rich applications will have a significant impact on our product roadmap and how we serve our clients and partners,” Tapjoy President and CEO Steve Wadsworth said in a statement. “The CPO role is vital at any technology company, particularly in a sector that moves as rapidly as mobile. This addition also speaks to the incredible opportunity ahead for Tapjoy, as we refine and focus our product roadmap and position the company for our next phase of growth.”

We last heard from Tapjoy when it announced its partnership with Kontagent, a mobile app analytics company known for its kSuite platform. The partnership with Kontagent allowed the two companies to release the app analytics platform, the Kontagent Partner Edition, for all developers and advertisers working with Tapjoy.

Tapjoy also recently brought on CFO and Executive Vice President at Acxiom Corporation Warren C. Jenson to the company’s Board of Directors.
