TechCrunch50: Dick Costolo, Satish Dharmaraj, Bradley Horowitz, George Zachary and Lior Zorea join Panel of Experts

TechCrunch50 is less than a week away, and we’re putting the final touches on what will be a jam-packed two days of startup launches, hallway pitches, and new ideas. We’re proud to announce new Twitter COO and FeedBurner founder Dick Costolo, RedPoint Ventures partner and Zimbra founder Satish Dharmaraj, Google’s social apps guru Bradley Horowitz, Charles River Ventures partner George Zachary and Perkins Cole attorney Lior Zorea will be rounding out our on-stage Panel of Experts at TechCrunch50. They’ll judge the fifty startups that will launch in front of a crowd of 2,000 or so eager attendees.

Each startup will present in front of a panel of successful entrepreneurs, VCs, and industry experts. In addition to these latest additions, we’ve already announced experts Marc Andreessen, Roelof Botha, Ron Conway, Don Dodge, Paul Graham, Jason Hirschhorn, Reid Hoffman, Tony Hsieh, Marissa Mayer, Tim O’Reilly, Sean Parker, Kevin Rose, Mike Schroepfer, Robert Scoble, and Yossi Vardi.

Two days, 50 launches, I can’t wait. The startups are already being put through their paces in rehearsals at a secret location (okay, it’s Sequoia’s offices). Each one will be a surpirse, of course, but there will also be some special announcements scattered throughout the two days by AOL, Microsoft, and Google, as well as a Facebook Developer Garage. We just posted the official conference agenda, found here. The 50 presenting companies won’t be released until the day of the conference, and there are other details we’re just not going to tell you quite yet, but the agenda should provide an idea of what we have in store.

More conference info is available over on the TC50 conference website. The event will be held at the San Francisco Design Center, a huge and beautiful venue where nearly 2,000 participants roamed last year.

There are still some tickets for the event, which can be purchased here courtesy of Eventbrite. And if you’re interested in demoing your product, we can even squeeze in a few more DemoPit and Exhibitor tables (e-mail us for details).
