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.

Our goal is not to build a platform; it's to be cross all of them.

The basis of our partnership strategy and our partnership approach: We build the social technology. They provide the music.

Our philosophy is that we care about people first.

I remember flying in, driving down 101 in a cab, and passing by all these tech companies like Yahoo! I remember thinking, 'Maybe someday we'll build a company. This probably isn't it, but one day we will.'

Facebook was not originally created to be a company. It was built to accomplish a social mission - to make the world more open and connected.
