Melding social networking and games with the "where's it at" component of mobile made HeyZap an app to watch.

In January, the start-up confirmed a new round of $4.3 million led by Union Square and Qualcomm that brought its total funding to $8 million.

HeyZap is also the first company to pay game developers in bitcoins using its monetization products, as VentureBeat has reported.

The gaming app added another monetary component to its business with an SDK that lets developers make money from helping users find games, says co-founder Jude Gomilla.

"This has become a really important part of HeyZap's business and many of the largest game developers are using HeyZap for monetization and user acquisition," he says.
