Following its strong expansion in 2012, and the $19 million VC investment it raised in early 2013, it's all systems go for Chartboost.

So the mobile games cross-promotion and monetisation outfit has announced it's opening its second office.

While San Francisco continues to be the 60-strong company's HQ, Amsterdam has been choosen as the location to enable it to better serve key European clients.

These include global players such as Supercell, Kiloo, King, Wooga and NaturalMotion.

Indeed, a third of Chartboost's clients - that's 4,700 apps - and a third of its traffic, come from Europe.

City of trade

The office will be head by ex-Gamundo and Virtual Fairground veteran Ilja Goossens, who will be joined by account managers, including some relocating from the US.

It's also looking to hire new employees.

"As a game developer myself, I have lived through the challenges of building and launching games," said Goossens, who takes the title regional director, Chartboost Europe.

"What drew me to Chartboost was their passion for helping developers achieve success and I'm excited to help our partners continue to grow their businesses worldwide."
