The Social Marketplace

The Investor: Jim Breyer, partner, Accel Partners

What he's backed: Brightcove, Facebook, Prosper

What he wants now: Social-networking sites may be sprouting like weeds, but none yet operates as a bona fide marketplace, with members buying and selling their own creations as much as they blog, link, and post. Breyer, who sits on Wal-Mart's board, is interested in backing an international network for indie artists, musicians, filmmakers, authors, designers, and other creative types from dozens of countries.

Ideally, the site would have the download and payment features to create what he calls a "micromarket" for members' wares. "There might be a Chinese student filmmaker with a five-minute film who wants to reach a niche of U.S. users," Breyer says. "He could find people willing to buy his films, and maybe a producer willing to bankroll more." Transaction fees would supplement ad revenue.

Breyer wants a five- to 10-person team to build a prototype using a peer-to-peer structure that would reduce bandwidth costs, and to identify core groups of users that would get traffic moving to the site.

What he'll invest: $10 million
