Mobile Ad Network Jumptap Raises $25 Million

Jumptap, a mobile ad network that has raised some $70 million over the last 6 years, has now raised $25 million more.

Previous investors AllianceBernstein, General Catalyst, Redpoint Ventures, Summerhill Ventures, Valhalla Partners and WPP participated in the newest funding round; the company says new investors came aboard as well, but won’t name them.

Much of the funding had previously been disclosed via a regulatory filing in April.

Jumptap is one of several well-funded mobile ad companies yet to be snatched up by a bigger player. But many have: Google bought AdMob, Apple bought Quattro Wireless, and last month ValueClick bought Greystripe for $70 million. Competitor Millennial Media, which raised its own big round in January, talks often about its ambitions to go public.

CEO George Bell joined the company less than a year ago; he had previously been a managing director at Jumptap backer General Catalyst.
