Brian Chesky is the CEO and one of the trio co-founders of Airbnb “Air Bed and Breakfast” a website that helps travelers find and rent lodging in rooms or apartments available in privately owned residents. The foundation of the company began when Brian and his then roommate and now co-founder Joe Gebbia devised a means of making money by renting out their rooms to guest of an industrial design conference in San Francisco who were desperately in need of accommodation as most hotels in the town were fully booked. Since its inception in 2008, the website now boasts over 1.5 million listings of rooms and apartments in 34,000 cities and 190 countries and has serviced over 30 million guests. Brian owns 13% stakes in Airbnb Inc.
