33Across Closes $9 Mln Funding Round led by Flybridge

My “friends,” or people I’m socially connected to, are a potential goldmine for some retailers.

That’s according to 33Across, which provides technology to track possible customers among friends, says co-founder Eric Wheeler.

For example, if I buy something off of eBay, 33Across identifies possible purchasers and shoppers that are socially connected me. The company places cookie on a browser allowing retailers to track potential buyers (users can opt out of the cookie, Wheeler says). “It’s not behavioral,” Wheeler says. “We identify the anonymous connections of consumers that are buying and shopping a certain brand.”

33Across’ social targeting platform has proved a draw to investors. On Wednesday, 33Across announced the close of $9 million in funding. Flybridge Capital Partners, a Boston VC firm, is leading the B round with participation from investors First Round Capital and QED Investors.

“To me, their social graph has proven to be an unbelievable platform for ad targeting,” says Jon Karlen, Flybridge’s general partner, who will be joining 33Across’s board.

Flybridge invested $6 million in the B round, Karlen says.

Since its founding in 2007, 33Across has raised more than $12 million in funding, Wheeler says. 33Across currently has over 200 customers including eBay and Sprint. Revenue in 2010 has grown 14x since 2009. “We’re very near profitable,” Wheeler says.
