As others have said on this thread, this model is not very good for frequent, repeated services that are provided by the same person each time. When that happens, it becomes really easy to cut the middle man out and pay the service provider directly.

These services are matchmakers, and the matchmaker can only really be expected to be paid to make the match... not in perpetuity. This is why services like Uber, where you only are matched with a particular driver for a single ride and are unlikely to be driven by the same driver again (at least not intentionally) work so well for a matchmaking service.

If you hire a music teacher, you aren't going to have a different one every week. You don't need the match making services after that first lesson. So why are you going to keep paying the matchmaker?

For one on one personal service yes.

For something where people get some value out of using the intermediary over and over, even if it's the same teacher, see Peloton.

I could see that idea working for remote music lessons if the teachers were great.
