The only company I've seen really trying something different is https://livekindred.com/
It's kind of like a really upscale couchsurfing. It's like a members-only network where you have to be a host too.
It costs a lot more than couchsurfing because you're getting a whole house and you pay for the cleaning, but since it's all home swaps there are no "professional hosts" and it still ends up being way cheaper than an Airbnb or a hotel.
Posted this somewhere else in the thread already, but I have seen one company doing it differently https://livekindred.com/
It's a member's only home swapping network, so it's more like fancy couch surfing than Airbnb.
