In December I wrote about how some successful entrepreneurs are starting incubators in a post called The Rise Of The Gentleman Hacker - "I’m hearing more and more about people who are simply setting up an office somewhere close to their multi-million dollar home in Silicon Valley or San Francisco, hiring a handful of hackers, and just building stuff to see what happens." One of those entrepreneurs is Omar Hamoui , the founder of AdMob. He sold Admob to Google in 2009 for some $750 million. He's started Churn Labs along with AdMob's first engineer, Mike Rowehl . And he's partnered with Sequoia Capital , one of AdMob's first venture investors, on the new project.
