What do you mean no similar service? You put it in your own sentence. couchsurfing.com was founded in 1999, launched the website in 2004, and still exists. It was, of course, a nonprofit founded on a principle of reciprocal generosity, not a way to make money, so it might be fair to say no similar service existed for homeowners looking to rent out spare rooms without a formal lease agreement or people looking to turn property into a hotel without it being zoned or licensed for that.
