Brad Burnham co-founded Union Square Ventures in 2004. The New York firm focuses on Web service and social media start-ups with the potential to change markets; its early-stage investments have included Del.icio.us, Etsy, FeedBurner, Foursquare, Kickstarter, Meetup, Tacoda, Tumblr, Twitter, and Zynga.
Burnham began his career in information technology at AT&T, where he held a variety of sales, marketing, and business development positions until 1990, when he spun Echo Logic out of Bell Labs. That venture was a catalyst for the creation of AT&T's investment arm, and when Echo Logic was sold in 1993, Burnham joined AT&T Ventures, becoming a general partner in 1996. There, he was responsible for 14 investments, including Argon Networks, Audible, Avesta Technologies, Classic Sports Network, Multex Systems, Paytrust, and Physicians Online. Burnham currently serves on the boards of Bug Labs, GetGlue, Hashable, Indeed, Meetup, Pinch Media, SimulMedia, and Tumblr.
