TubeMogul snagged $20 million in its third round of financing.

TubeMogul is a platform where brands can buy video ad opportunities in real-time. Real-time bidding and video advertising have become increasingly popular over the past couple years, and TubeMogul’s technology helps brands get the most out of the buying process.  The platform was “built for branding,” meaning it was designed with marketers’ needs in mind. Advertisers maintain significant control over their campaigns and receive reports about their impact.

This investment was led by Northgate Capital, with participation from existing investor Trinity Ventures and Foundation Capital. The money will be used to hire more people and make technological advancements to the platform.  It brings TubeMogul’s total capital raised to $35 million to date.
