If my experiences as an early-stage founder have taught me anything I can assure you that we don’t know our asses from a hole in the ground. Founding a company is a game where you throw shit at the wall as quickly as you possibly can until something sticks and then you desperately try to figure out why it stuck. If you can figure that out, you might just have product-market fit.

This is especially true for a first time founder. You learn as you go.
