Sheryl Sandberg announced her resignation as Facebook's chief operating officer on Wednesday, after 14 years as one of the most powerful figures at a company that transformed Silicon Valley.
During her time at Facebook, now Meta, she witnessed the company's meteoric rise as well as an ongoing storm of controversies.
Meta CEO Mark Zuckerberg announced in a Facebook post that Javier Olivan will be Meta's new COO, though the position will be different from the one Sandberg has held for the past 14 years.
Sandberg, who unexpectedly lost her husband Dave Goldberg in 2015, stated that she is "not entirely sure what the future will bring."
Sandberg was a key figure in growing Facebook from a free social network conceived in a Harvard dorm to one of the world's most dominant social media platforms, with nearly 3 billion users worldwide.
Outside of Facebook, she became a public face of the company, sitting for interviews in the midst of crises and mingling with policymakers debating regulations that would affect the company.
