Using Bunchball's Nitro platform, clients can "gamify," or add game play mechanics, to their Web sites, Facebook presence or non-game applications to boost engagement. Joining Bunchball as chief revenue officer last month was Steve Patrizi, who formerly led U.S. sales for LinkedIn. Gartner predicts that at least 70% of Global 2000 companies will have at least one gamified app by 2014. --Mark Walsh
