I feel bad for you. But I think you have a few choices:
a) Forget about doing difficult things and focus on something easy like dating, swipe left/swipe right app. It is not that Europe does the hard things like compilers, it is that America does the easy things like dating or cat apps or farting and stuff. However, there is hope. Look at what Slack is doing with yet another messaging app. Is there another app that is simply "a bad solution" which you can come up with a better, easier, more delightful alternative?
2) If you already did the hard stuff, what about packaging it with other elements of the stack and providing a fully optimized stack? Then you can offer it as a solution to enterprises. It is hard though. Enterprise sales.
3) Don't open source. Get paid for what you do.
4) Open Source but charge for the services around it. Consulting services. But you are already doing something along these lines.

I am sure there are others.
