operates Couchsurfing.com, a hospitality service and social networking website.

The website provides a platform for members to stay as a guest at someone's home (homestay), host travelers, meet other members, or join an event.

Members complete a profile page that includes information about themselves, their interests, the skills they can teach others, their favorite music, movies, and books, and photos of themselves and of the lodging they offer, if any.

Members searching for lodging or a meeting can search for other members using several parameters such as location, age, gender, interests, availability to host, type of lodging offered (if any), and languages spoken, and then send messages to the members with whom they want to stay or meet.
