I'm building a new audio streaming platform that I would love to make 100% free to use for both the listener and the artists. I aim to target unsigned artists in South Africa who would love to grow their fan base. -I don't like adverts on websites, so I am not looking to follow that revenue model. -I don't want to charge users a fee for a service that will be data intensive, in a country where data is so expensive ZAR 150(+-$11). -I don't like the subscription based model because it creates exclusion and I would love to get the artists content to as many ears as possible. Is there any other model that could at least help with the cost of infrastructure or one that could possibly be utilized to insentivise the artists?
