Airbnb, Inc. (ˌɛərˌbiːɛnˈbiː ) is an American San Francisco-based company operating an online marketplace for short- and long-term homestays and experiences. The company acts as a broker and charges a commission from each booking. The company was founded in 2008 by Brian Chesky, Nathan Blecharczyk, and Joe Gebbia. Airbnb is a shortened version of its original name, AirBedandBreakfast.com. The company is credited with revolutionizing the tourism industry, while also having been the subject of intense criticism by residents of tourism hotspot cities like Barcelona and Venice for enabling an unaffordable increase in home rents, and for a lack of regulation. After moving to San Francisco in October 2007, roommates and former schoolmates Brian Chesky and Joe Gebbia came up with an idea of putting an air mattress in their living room and turning it into a bed and breakfast. In February 2008, Nathan Blecharczyk, Chesky's former roommate, joined as the Chief Technology Officer and the third co-founder of the new venture, which they named AirBed & Breakfast. They put together a website that offered short-term living quarters and breakfast for those who were unable to book a hotel in the saturated market. The site Airbedandbreakfast.com officially launched on August 11, 2008. The founders had their first customers in the summer of 2008, during the Industrial Design Conference held by Industrial Designers Society of America, where travelers had a hard time finding lodging in the city. After the founders raised 20,000 in funding in exchange for a 6% interest in the company. With the website already built, they used the Y Combinator investment to fly to New York to meet users and promote the site.
