Video advertising and analytics startup TubeMogul closed a $10 million Series B financing. The round was led by Foundation Capital , with existing investors Trinity Ventures and Knight's Bridge Capital Partners (where WallStrip and StockTwits founder Howard Lindzon is a partner) also putting in more money. Previously, the company raised $5.4 million. Twitter CEO Dick Costolo is a board member and one of its angel investors. TubeMogul is best known as an online video analytics service, but it makes its money as a data-driven video ad platform. CEO Brett Wilson projects revenues this year will hit $10 million, up from $2.6 million in 2009. "We just did a $1.1 million month in September," he says.
