I joined Facebook in 2008 - 80 million users, smaller than Myspace, 500 employees. When I left it was 5,500 employees, $5 billion in revenue, over a billion users.

And I joined Facebook in 2008, and it's important context because it was 80,000,000 users at the time. We were smaller than Myspace. It was, you know, 270,000,000 in revenue, 500 employees. It did not feel inevitable. Most people thought we were gonna sell it to Microsoft. When I told people I was going there, they were like, isn't that place just like a site for college kids? And so I was there for five years, and it was a crazy five years. When I left, it was 5,500 employees, 5,000,000,000 in revenue, over a billion users.
