If you're trying to be like Vercel—it's a red flag for any reasonable person when you clearly spent more effort on your landing page than your actual product. What made Stripe so successful is that, I personally would not even attempt, like you said, "integrations with providers" "bank partnerships" "compliance screens" because that sounds basically impossible.

we're lucky enough to have a founding designer who makes it look easy in about a week - we spent about a year on the product in silence.
