Couchsurfing is a hospitality exchange and social networking website that allows members to stay at other members' homes or host travelers for free. Members create profiles to connect with other members as either hosts offering their couch/space or surfers looking for places to stay. The website also facilitates social events and groups for members to connect. While Couchsurfing aims to be non-profit, it faces challenges in balancing this with business needs and maintaining trust within the community.
