There has to be a VC in this thread, go ahead and fund a GitHub competitor that offers a flat monthly(yearly?) rate.

Focus on the enterprise. Something like a 3000$ minimum yearly price. Direct customer support with real engineers no questions asked.

Need someone to setup your CICD, that's another fee, but on staff engineers will get it done.

Edit: I'd even imagine a company like this can bootstrap, I'd need help though. Would probably take 4 skilled SWEs about 6 months for an MVP.
