AirBnB happened because Brian Chesky couldn't pay his rent, but did have some space.
AirBnB spent 5 months interviewing their first employee, before they hired someone and in their first year, they only hired 2 people.
In June 2010, I moved out of my apartment and I have been mostly homeless ever since, off and on. I just live in Airbnb apartments and I check in every week in different homes in San Francisco.
