YuMe co-founder Jayant Kadambi has replaced Michael Mathieu as CEO of the online video ad network, the company said today. The move comes as YuMe is pushing to expand its technology platform for advertisers and publishers across all major media channels from mobile to TV. Mathieu, who has helmed YuMe for the last three years, will remain on the company's board. 

The CEO shakeup follows the hiring of Tim Laehy, formerly of CloudShield Technologies and Covad Communications, as its new CFO in June. Earlier this year, YuMe named Bryan Everett as executive vice president, business development, and Ed Haslam as senior vice president, marketing.

In the last few years, YuMe has emerged as one of the Web's largest video ad networks; publishers such as MSN, MSNBC Digital Network, IDG Entertainment and Glam Media use YuMe's ACE ad management platform.

Over the last six months, YuMe has taken steps to extend its video ad technology beyond the desktop. In June, it acquired U.K.-based mobile video company Appealing Media to accelerate its push into mobile, as well as opening a London office to serve as base for European expansion. That followed the company's hiring of a half dozen top executives from mobile video ad network Transpera, including founder Frank Barbieri.

Other recent YuMe initiatives include a partnership with Roku to integrate video advertising into its streaming media player, and a deal with video ad platform Ooyala to provide monetization tools to content creators. 

YuMe said Wednesday it has tripled revenue growth for each of the last three years, but declined to provide actual sales figures. It says it's already profitable. The Redwood City, Calif.-based company has raised a total of $51 million in venture funding to date from investors, including Menlo Ventures, Accel Partners, BV Capital, DAG Ventures and Khosla Ventures.
