TokBox, the provider of a simple video chatting service, has raised a $10 million second round led by Bain Capital Ventures, with participation from past backer Sequoia. The company was actually incubated out of Sequoia, which led the firm’s initial $4 million round last year. The SF-based firm allows users to embed video communications in various environments, including Facebook, blogs and a desktop chat bar. The raise means that companies with growth but no clear business model can still raise substantial sums: CEO Nick Triantos told VentureBeat that the company is still in growth mode, and that a variety of revenue options were still on the table. He also said that most of the money from the first round is still in the bank. Release.
