Emily White

White likes to go where the heat is: first, she helped run local and commerce businesses at Google, where she was a protégé of Sheryl Sandberg—who brought her over to Facebook, where she helped integrate ads into the company’s mobile experience before moving over to the newly-acquired Instagram as director of business operations. Last December, she joined Snapchat as COO, tasked with helping turn it into a viable business. White’s also a director of Lululemon.
