Sheryl Sandberg is stepping down as COO of Meta

It’s the end of an era. After 14 years, my good friend and partner Sheryl Sandberg is stepping down as COO of Meta.  When Sheryl joined me in 2008, I was only 23 years old and I barely knew anything about running a company. We’d built a great product — the Facebook website — but we didn’t yet have a profitable business and we were struggling to transition from a small startup to a real organization. Sheryl architected our ads business, hired great people, forged our management culture, and taught me how to run a company.
