Sheryl Sandberg is the chief operating officer at Facebook, where she oversees all aspects of the company’s business operations. Sandberg, who is considered one of the most powerful people in Silicon Valley, is widely credited with bringing a healthy dose of “adult supervision” to Facebook, and transforming it into a multi-billion dollar business. Prior to Facebook, Sandberg was vice president of global online sales and operations at Google, where she helped build the company’s wildly-profitable online advertising business. Earlier in her career, Sandberg was chief of staff for Clinton-era Treasury Secretary Larry Summers.
Sandberg has become an inspirational role-model for her advice that young women should “lean in” to their careers, and earlier this year, she published a best-selling book with that title. In addition to Facebook, Sandberg serves on the board of the Walt Disney Company, Starbucks, Women for Women International, the Center for Global Development and V-Day. Last year, Sandberg was named to the Time 100, the annual list of the 100 most influential people in the world. Thanks to her Facebook stock options, Sandberg is estimated to be worth more than $1 billion.
