Our philosophy is that we care about people first.

The thing I really care about is the mission, making the world open.

The question isn't, 'What do we want to know about people?', It's, 'What do people want to tell about themselves?'

It wasn't until we got our first office in Palo Alto where things became more like a company. We never went into this wanting to build a company.

The main Facebook usage is so big. About 20 percent of the time people spend on their phone is on Facebook.

My goal was never to just create a company. A lot of people misinterpret that, as if I don't care about revenue or profit or any of those things. But what not being just a company means to me is not being just that - building something that actually makes a really big change in the world.
