“Cross-Device” Ad Tracker Drawbridge Rounds Up $6.5 Million From Sequoia, Kleiner Perkins

Drawbridge, an ad tech start-up founded by AdMob engineer Kamakshi Sivaramakrishnan, has raised $6.5 million from Sequoia Capital and Kleiner Perkins Caufield & Byer. Drawbridge says it can help marketers target potential customers by tracking them as they move around from device to device — like from a laptop to an iPhone. Sivaramakrishnan put in six months at Google after it acquired AdMob, before starting her own company.
