Watch The TechCrunch Disrupt Hackathon Live

Hundreds of hackers participated from late last night to early today morning at the fourth annual TechCrunch Disrupt Hackathon in San Francisco, building in teams and waking up or popping enough coffee and Redbull this am in order to show off their hacks to judges including Salesforce’s VP of Open Cloud Standards Kevin Marks, Betfair’s Vice President of Mobile Engineering Raj Vemulapalli, Google’s Rohit Khare, MyBlogLog and OneTrueFan founder Eric Marcoullier, and’s Director of Engineering, Mobile and Platforms Vishal Shah.

This year’s San Francisco Hackathon was our largest showing ever (over 700 hackers registered for the event), and what the hack teams came up with in the past 24 hours are about to be judged on stage with each team given 60 seconds to present. We’ll be looking for the next GroupMe, a startup conceived and built at New York’s Hackathon in 2010. GroupMe was just acquired by Skype a few weeks ago.
