24-year-old Siberian entrepreneur Danil Kozyatnikov was welcomed to the LeWeb main stage by organizer Loïc Le Meur to discuss his online treasure-hunting app for mobile devices, Quest.li. It was an energetic presentation, with Kozyatnikov ripping off his T-shirt (there was another underneath) and delivering much of the speech in rhyming verse. Small wonder he's raised half a million in start-up funding at last year's LeWeb.
