Former Google and AdMob scientist Kamakshi Sivaramakrishnan has founded a startup, Drawbridge. The company has announced $6.5m in Series A funding from Silicon Valley venture capitalists Sequoia Capital and Kleiner Perkins Caufield & Byers.
Drawbridge is developing a self-learning cross-device advertising solution that brings desktop-like targeting to mobile advertising, the company says. 
“Today, targeting in mobile display advertising is more about the device than the audience behind it,” Sivaramakrishnan says. “Consumers now have multiple touch points across various screens. We want to leverage this emerging user behavior and unlock the power of cross-device data to impact targeting in mobile. The Drawbridge platform makes it possible to understand behavior on any device and use those insights to effectively reach mobile audiences.”
