Ning’s Marc Andreessen, Sequoia Capital’s Roelof Botha and Google’s Marissa Mayer will return to our third-annual TechCrunch50 conference Panel of Experts September 14 – 15 in San Francisco. Our experts judge the fifty startups launching at the event and discuss each of the demos on stage as a group. Marc, Roelof and Marissa have been experts since our first conference, and we receive lots of positive feedback to have them return each year. We have an amazing line-up of new and returning experts, and additional judges will be announced over the coming weeks.

If you’re a new startup, and want a shot to launch at TechCrunch50 and pitch our expert advisors on stage, you have until June 30 to submit your application. No need to wait until the last day, we’re actively reviewing companies and extending offers now. We want to hear from you. The only rule at TechCrunch50 is that you have to launch your product for the first time on stage at our conference. We showcase a diversity of technology verticals (consumer, enterprise, mobile, hardware, etc), including funded and unfunded companies from all corners of the world.

All the details for the conference are here. TechCrunch50 is an action-packed conference where fifty new startups launch over two days. The event will be held at the San Francisco Design Center, a huge and beautiful venue where we packed nearly 2,000 participants last year.

Tickets for the event can be purchased here courtesy of Eventbrite (extra early-bird pricing is available until June 30).
