Sheryl Sandberg

COO
Facebook

Sheryl Sandberg last spoke onstage at D in 2006, when she appeared with CEO and co-founder Mark Zuckerberg. Since then, a lot has happened at the social networking giant – including a tumultuous IPO and a need to quickly develop its mobile business. Sandberg oversees Facebook’s business operations, including sales, marketing, business development, legal, human resources, public policy and communications. Most recently, she has written the bestselling book “Lean In: Women, Work, and the Will to Lead.” Prior to Facebook, Sandberg was VP of global online sales and operations at Google, served as chief of staff for the United States Treasury Department under President Bill Clinton, and was an economist with the World Bank.
