Airbnb is an American San Francisco-based company that operates an online marketplace for short- and long-term homestays and experiences. It was founded in 2008 by Brian Chesky, Nathan Blecharczyk, and Joe Gebbia, and the name Airbnb is a shortened version of its original name, AirBedandBreakfast.com. Airbnb is a community built for belonging, where hosts can offer anything from a spare room to an entire home for rent to travelers looking for a place to stay. Airbnb also offers experiences, which are in-person or online activities hosted by local experts, and adventures, which are fully immersive expeditions. Airbnb for Work is another service that offers everything needed to do your job on the road, from top-rated places and collaborative spaces to team-building experiences and administrative tools that make managing travel easier than ever.

Airbnb has a review system in which guests and hosts can rate and review each other after a stay, and hosts and guests are unable to see reviews until both have submitted a review or until the time period to review has closed. Airbnb has become one of the most successful and valuable start-ups in the world since its founding in 2008, and has had a significant impact on the industry of renting homes and the hospitality industry more generally. Airbnb has made travel more accessible and affordable for many people, and has disrupted the hotel industry.
