San Francisco-based BrightRoll, an online video ad network, has raised a $5 million second round from True Ventures and Adams Street Partners, reports PE Hub, citing SEC filings. The company raised an unspecified first round last November from True Ventures, along with several angels. Since its first funding, a number of companies in the space have raised money, including YuMe and Podaddies. Like the competition, Brightroll offers a variety of ad formats that work across multiple video platforms.
