Really complicated and nuanced stuff unfortunately. What's clear is that one can incorporate, get office space, build a product, and even get funding and that one can't get paid cash for work done. Everything else in between is nuanced, such as generating revenues if not taking a draw or cut. I'd be happy to talk this through with you and anyone else but my general approach is that once the business is real (not a great definition, I know) and not just a hobby or side project, one needs to get work authorization.
