Sheryl Sandberg: Facebook’s COO

Sheryl Sandberg is the chief operating officer of Facebook. Before this position, she was Google’s vice president of global online sales and operations. She arrived at Facebook in 2008 after this company had lost $56 million. By 2018, under her financial oversight, Facebook made a profit of $22.1 billion, and ad revenue increased by 38%.

Sandberg authored the best-selling book “Lean In: Women, Work, and the Will to Lead.” She also became the first female to sit on Facebook’s board of directors. In 2014, she became a billionaire, largely before she owned much Facebook stock.
