Having a clear value proposition and developing a unique insight is almost certainly not enough for securing funding. Doubly so in this environment (exceptions like Mistral AI exist, but I wouldn't bet on that). Build an MVP, get some traction (aka paying customers), prove out your value prop. I don't want to be too negative (trying to do something similar in fact!), but there's definitely some real upfront work and hustle required before you can start even thinking about measuring successes.
