Seesmic Raises Another $6 Million Round

Video conversation startup Seesmic raised another $6 million in a series B financing. The round was co-led by Omidyar Network and Wellington Partners. The series A financing last February, which was also for $6 million, was led by Atomico (the investment vehicle of Skype founders Niklas Zennström and Janus Friis), and included angel investors Reid Hoffman, Steve Case, Jeff Clavier, Ron Conway, and Martin Varsavsky. (Disclosure: TechCrunch founder Michael Arrington was also an angel investor in the first round).

Seesmic is designed to encourage video conversations among loose social groups (many of whom find each other on Seesmic). Since it launched in a private alpha last October, it’s attracted 21,000 users who post about 2,500 videos a day. Those videos, in turn, are watched about 300,000 times a day. Since last week, Seesmic has opened up its doors to all comers.

The company also owns Twhirl, a desktop Twitter/FriendFeed client that has been downloaded 400,000 times. Founder Loic Le Meur estimates that Twhirl accounts for 12 percent of all Twitter messages, and 5 percent of all FriendFeed comments.
