Seeking to boost agency and client confidence in a still nascent market, video ad network Tremor Media on Tuesday announced a partnership with digital media-verification company DoubleVerify.

Going forward, Tremor will rely on DoubleVerify's proprietary patent-pending technology for increased accountability and transparency of video ad campaigns, according to Jason Glickman, CEO of Tremor Media.

"Our partnership with DoubleVerify allows us to provide greater transparency and accountability to advertisers," said Glickman. "DoubleVerify bolsters our network integrity."

Tremor serves in-stream and in-banner video ads across a network of over 1,500 mid-tier and premium sites including WWE.com and WSJ.com. The company has increasingly sought TV ad dollars, which believes will increasingly migrate online.

In May, DoubleVerify launched its real-time verification solution for online ad transactions. Tracking the delivery of clients' ad campaigns theoretically allows marketers and their agencies to identify and remove budget waste from their campaigns, safeguard the reputation of their brands online, uphold regulatory compliance requirements, and verify that they fully capitalized on their marketing opportunities.

Earlier this year, eMarketer revised its estimate for online video ad spending growth in 2009 from 45% to 43.5%, or $1.1 billion. Forrester Research projects 2009 spending lower, at $870 million.

This summer, Tremor Media co-founder and chief operating officer Andrew Reis and co-founder and Chief Strategy Officer Jesse Chenard left the company in a management shake-up.

In turn, Mark Pinney, Tremor's then chief financial officer, assumed an expanded operational role as part of the restructuring. Pinney joined the company last year after serving as head of business planning at AOL's Platform A and as CFO at behavioral targeting firm Tacoda.

In February, Tremor announced closing a third-round financing of $18 million led by Meritech Capital Partners to help fuel its international expansion. To date, it has raised a total of just over $40 million in venture capital.

This summer, DoubleVerify itself closed a $3.5 million Series A financing found led by Blumberg Capital, with participation from First Round Capital, Genacast Ventures and private investors.
