TokBox, the Sequoia backed video chat startup, has closed a $10 million Series B round led by Bain Capital Ventures, with Sequoia also contributing. The round brings TokBox’s total funding to around $14 million. As part of the deal, Bain’s Scott Friend will join the company’s board.

TokBox offers a Flash-based video chat service that requires no extra plugins. The service has gotten rave reviews from a number of our readers for its ease of use. While the service offers basic social network functionality, there’s no account required to participate in a chat – users need only browse to the URL that gets assigned to each chat room.

Last month TokBox positioned itself to more directly take on traditional web chat and IM clients like AIM and Skype by releasing a new AIR desktop client.
