Sheryl Sandberg: Chief operator

Sheryl Sandberg’s trajectory from a high-achieving government official to one of Silicon Valley’s most influential executives highlights the unique path of a billionaire who built wealth as an employee rather than a founder. After mastering operational efficiency at the World Bank and the U.S. Treasury, she joined Google during its rapid ascent, later becoming Facebook’s Chief Operating Officer. Her pivotal contribution involved transforming Facebook into a profitable enterprise through targeted advertising, a model that cemented her status as a key architect of the attention economy. Beyond her corporate success, she shaped public discourse on gender in the workplace through her book *Lean In*, though her legacy remains polarized by controversies surrounding surveillance capitalism and data privacy. Despite her immense financial success, her unconventional habit of aggressively selling stock options throughout her tenure left significant potential wealth on the table.
