Stealth start-up Booyah, a web and mobile content company founded by three gaming vets, has raised roughly $4.5 million from VC firm Kleiner Perkins, according to PEHub. One clue about what binds the two together: the company is advertising for a “senior iPhone engineer” and an “iPhone engineer” and says notices of its service could incur SMS costs. KP, of course, has an iPhone developers fund. Founders Sam Christiansen, Keith Lee and Brian Morrisroe, worked at World of War home Blizzard Entertainment. Their own site also mentions experience with Activision and Insomniac Games, along with this about how they spend their days: “creating compelling experiences on mobile and web platforms that inspire personal discovery and provide social entertainment. ” Booyah’s tagline: “What excites you about life?”
