Jana Mobile, a provider of software for mobile service providers, has raised $15 million of venture capital, according to a new filing by the company with the Securities and Exchange Commission.

Jana is the world's largest rewards platform. With integrations into the billing systems of 237 mobile operators, Jana can instantly reward 3.48 billion emerging market consumers in 70 local currencies with prepaid airtime.

Global corporations are using Jana to understand, acquire, and retain emerging market consumers. Jana's airtime rewards platform can be easily integrated and configured to reward consumer actions including trial (registration, app downloads), engagement (watching a video, uploading a photo), advocacy (referring a friend), and product purchase (airtime rebates). With every action that it rewards, Jana gathers rich data about consumers and their behavior.
