Sheryl Sandberg: Chief operator

As COO of Facebook, then Meta, Sheryl Sandberg is a rarity among billionaires. She made her money as an employee rather than as a founder, creator, or company owner.

BBC business editor Simon Jack and journalist Zing Tsjeng follow Sandberg’s career, from running aerobics classes in her teens to overseeing one of the world’s biggest corporations. She spent time in government before taking a role at startup called Google, before positioning herself as a spokesperson for female leadership with her book Lean In.
