Seth Priebatsch founder, SCVNGR

With his mobile location-based game platform SCVNGR, Priebatsch is tapping into the "gamification" zeitgeist and the idea that everything in life can be played like a game. Though SCVNGR is still an infant compared to rivals FourSquare and Gowalla, its incentives-based "check-in" system emphasizes loyalty, which Priebatsch thinks will give it a major advantage as it gains traction. It has attracted nearly $20 million in venture funding and more than one million registered users to date. Priebatsch, who at 22 has already delivered a SXSW keynote and hosted a TED talk, could just be the next the next household name in tech.—Devon Pendleton
