Run The Jewels started out the same way. Outside of the fact El-P and Killer Mike are much more established artists then the folks from Sault, Run The Jewels sold a TON of merch both online and offline and also got a grip of money from touring, so they were able to profit in the end.

I do wonder how the folks in Sault are turning a profit. Perhaps Sault is almost like a side-group from the members and they make enough of a living from the works they release when they are actually credited and acknowledged.
