Twitter has raised a new round of venture capital, USD 200 million, valuing the company at USD 3.7 billion. The financing brings the total raised by the three-year-old company to USD 360 million. It was last valued at USD 1 billion when it raised money in September 2009. A new investor, Kleiner Perkins Caufield & Byers, contributed USD 150 million, and existing investors, which include Union Square Ventures, Benchmark Capital and Spark Capital, invested USD 50 million, All Things Digital reports citing people familiar with the matter. A Kleiner Perkins partner did not join Twitter's board, but the company did add two new board members: Mike McCue, a co-founder of TellMe and current CEO of Flipboard, which transforms Twitter feeds into a more attractive format, and David Rosenblatt, former CEO of DoubleClick, the online advertising company now owned by Google. A Twitter spokesman confirmed the funding and appointments, and Twitter CEO Dick Costolo wrote about the funding in a company blog post. Separately Twitter launched a new portal for business users of the micrblogging service. Business.twitter.com offers information and case studies on how businesses can use Twitter effectively.
