HelloBerlin_v1_copyTune, the mobile marketing startup formerly known as HasOffers, announced today that the company is expanding the reach of its offices to continental Europe by opening a new branch in Berlin.

The office, which will primarily be focused on business development and account management, is being led by former Myspace and Muzu.tv executive Julian Schroll. Schroll, in turn, will report directly to Ralf Hirt, Tune’s Chief Revenue Officer. The company already has offices in 6 other cities worldwide, including London, Seattle, San Francisco and Tel Aviv.

“Being originally from Germany myself, I’m personally proud to open our first continental European office in Berlin, one of the centers of mobile innovation,” Hirt said.

It’s an important step for Tune, which is hoping to expand the reach of its HasOffers, MobileAppTracking and MobileDevHQ products. Right now, Tune products are used with a number of high profile apps, from companies including Uber, Gilt, Sephora and Supercell (the makers of Clash of Clans).

Today’s announcement is just one more move in a period of massive growth for Tune. The company has more than doubled in size to 215 employees, up from 85 a year ago, and it’s on pace to bring in more than double its 2013 revenue of $19 million. In recognition of its ongoing growth, the company just ranked 88th in Inc’s list of the 5000 fastest growing companies. Earlier this year, Tune opened another new office in South Korea in order to bolster its reach in Asia.

The news comes shortly after the company announced that it had purchased MobileDevHQ, a startup that provides services to developers looking to boost downloads of their app. Earlier this summer, Tune (then HasOffers) announced that it was investing an undisclosed sum in MobileAds, which was the first it took equity in another firm.
