Analytics service Kontagent has closed a $12 million second round of funding led by Battery Ventures, with participation from existing investors Maverick Capital and Altos Ventures.

According to a press release announcing the funding, Kontagent plans to put the money toward expanding further into mobile and open web markets, as well as increasing the level of depth its platform can reach in gathering and analyzing data . Currently, the bulk of the company’s business is on Facebook where its analytics platform allows developers to track general and ad traffic, retention, and monetization trends within an app, as well as a viral A/B split test platform. Its clients include EA, Warner Brothers Interactive, Ubisoft, Gaia Online, and A&E Networks Digital.

Kontagent is one of the oldest analytics tool providers for Facebook, dating all the way back to 2007. Its contemporary rival platforms have long since moved off of Facebook while newer players have emerged to horn in on the territory. The key to this segment of the market likely lies in a platform’s ability to provide analysis for cross-platform products. As social game developers look to expand onto mobile and other social networks, it makes sense for analytics service providers to offer data on all possible networks and devices.

Kontagent’s first round of funding came in at $1.25 million. Combined with today’s funding, fbFund winnings, and around $4 million in additional funding puts the company’s total funding at $17.75 million.
