Your Disrupt SF Startup Battlefield Final Judges: Marissa Mayer, Roelof Botha, Michael Arrington, Chris Dixon, David Lee And David Sacks

Choosing this year’s Startup Battlefield winners is a tough job. We’ve had a record number of applications for our startup competition happening in two weeks at Disrupt SF, and the 30 companies we’ve picked out of the inbound are exceptionally strong.

Thankfully, we have an experienced team of entrepreneurs and investors on board to help. Marissa Mayer has graciously agreed to continue her traditional role as a Disrupt finals judge, even though she’s just taken over as CEO of Yahoo (and is about to have a child!). Two other long-time finals judges are also back. Accomplished Sequoia Capital partner Roelof Botha will be offering his incisive wit and seasoned insights to the presenting entrepreneurs. And the man himself, TechCrunch founder Michael Arrington, will be on board dishing out startup advice in addition to conducting his iconic interviews.

Chris Dixon, the NYC-based entrepreneur/investor/tech pundit, is flying out to join us from the East Coast. We also have the privilege of SV Angel head David Lee’s early-stage wisdom. And, who better to round out the team than David Sacks — you know, the founder of TechCrunch 50 winner and $1.2 billion Microsoft-acquired Yammer.
