App monetisation exchange Inneractive has secured US$3.5 million in Series B funding which it plans to use to increase staff numbers and open several new offices around the world.

“This new round will help us bring more talent on board as well as facilitate our plan to increase our impressive growth and open new offices in NYC, India and Singapore in addition to the ones in London, Tel Aviv and the Silicon Valley,” said Inneractive CEO Ziv Elul.

Inneractive’s platform gives app developers access to a range of ad networks with more than 120 advertisers.

The investment comes from Evergreen Venture Partners which led Inneractive’s previous financing round in 2010 and has also put money into video discovery platform Taboola and mobile technology company Flash Networks. Evergreen is joined by new and existing private investors from Europe and the US, bringing total investment to US$8.5 million.

“Inneractive is showing tremendous growth and traction. The mobile advertising and monetization space is growing exponentially and Inneractive is at the cutting edge with a leading exchange that is already monetising apps across all platforms,” noted Evergreen general partner Adi Gan.
