AirBnB is an online marketplace that connects people who want to rent out spare rooms or entire homes to temporary guests. The company was founded to provide an alternative to expensive hotels by allowing tourists, travelers, and others to book unique accommodations from local hosts and property owners. While AirBnB was profitable at one point, it plans to go public in November 2020 and will likely face challenges from competitors in the hospitality industry as well as addressing security issues to ensure guest safety.
