The answer can depend on some of the architectural choices you made when you prototyped your product. If the original use-case has changed significantly, and you find yourself fighting the codebase to get it to do what you want today, the technical debt is something to worry about. The same thing applies if you cannot scale to serve clients requiring a lot more volume than what you anticipated originally. It's possible that some clients have modified the original use-case they wanted when they signed-up with you, so your product must evolve to keep serving them. This may require refactoring, whether p/m fit was achieved or not.
