Location: San Francisco

TechCrunch Disrupt opens with the Hackathon on Sept. 8-9 and the conference on Sept. 10-12. The focus is on tech startups, with a Startup Battlefield that gets companies in front of investors, media, a panel of judges and a large audience. The last Disrupt SF brought us Reid Hoffman, Scott Cook and Vinod Khosola offering insights.
