Yah, I get it… building billing and management of users, licenses, etc is really complicated and not your core expertise. It’s a huge amount of effort for something that is not the primary value-add of the product. We at Roon spend way too much energy working on this. We have a person on staff whose primary job is to deal with billing support! I wish we didn’t, but it’s the only thing allowing us to grow like we are.
Anyway, if you are curious, Stripe Connect is a great way to pull off the majority of this stuff with semi-minimal effort.
There are additional business alternatives, that maybe we should talk about more seriously. For example, deeper integration of your DSP technologies as an optional component in Roon could allow you to get compensated without having to worry about billing/user-management and get you a great anti-piracy mechanism as well. Obviously, it would be more non-core-value technical work and a different product to HQPlayer. If this sounds interesting, PM me.
