Arc takes ~15-30%, they just take it from the client's side instead of the freelancer; but your rate isn't the one the client is paying. I do like them a lot though and have gotten clients through them (and codementor; though that last one is, too, getting polluted with very-low-level coders just randomly accepting jobs they do not have the skills for; having used it as a client recently, I've been less impressed)
