Airbnb is an American San Francisco-based company operating an online marketplace for short-term homestays and experiences. The company acts as a broker and charges a commission from each booking. Airbnb was founded in 2008 by Brian Chesky, Nathan Blecharczyk, and Joe Gebbia. The company's original name was AirBedandBreakfast.com, which was later shortened to Airbnb. Airbnb is credited with revolutionizing the tourism industry, but it has also been the subject of intense criticism by residents of tourism hotspot cities like Barcelona and Venice for contributing to overtourism. The company has expanded globally and has established its European headquarters in Dublin. Airbnb offers a wide range of accommodations, including apartments, houses, villas, and unique stays like treehouses and yurts. The company also offers experiences, which are activities hosted by locals that allow travelers to immerse themselves in the local culture.
