It's all go for value-exchange advertising platform SponsorPay.

According to the company, mobile revenues in May 2013 were up 308 percent year-on-year.

Perhaps more significantly, this marked the first time the technology, which supports Facebook, web, iOS and Android, has seen the majority of its revenue coming from mobile devices.

The background to this is the more than 40 million installs the company has delivered to clients such as GREE, DeNA and Groupon over the past 12 months.

Indeed, it says it can now deliver a 24 hour burst of 300,000 installs.

Doing it best

SponsorPay also pointed to the impact of its new Mediation Platform, which launched in March.

It claims that its yield optimisation smarts have driven up eCPMs for clients such as Droidhen, Animoca, Alawar, Nordeus and Tagged.

"We're committed to help resolve some of the key monetisation and user acquisition challenges facing the industry today," said CRO Janis Zech.

"Our mission is to drive value in the mobile app ecosystem, and enable developers to focus their energy and passion on creating great apps."

Firm handshakes

Keeping the momentum going, the company has announced two new hires.

Benjamin Chen - previously GREE, DeNA and Playdom - joins the San Francisco office as SVP of business development and developer relations, while Maroje Guertl takes up the reins of VP, finance and strategy at SponsorPay's Berlin headquarters.

And further bulking up the company's US presence, CEO Andreas Bodczek is relocating to the Bay Area in July.

"We're excited about this tectonic shift to mobile and have been investing heavily in building out our next generation advertising platform," he said. 

"It is an exciting time to join SponsorPay and my pleasure to welcome our newest executives."
