The hard part for B2B is the sales not tech. You are better off wining and dining a sales guy as your co founder than doing more vibe coding.

The hard part is even knowing what someone would pay for. I don't know if a sales guy knows that or not.

Sales at this level is a negotiation. And, either way, it's common to start your price in the neighborhood of the competition's price.

What does this have to do with my comment? You don't get to the "negotiating a price" part if you never knew what the customer might buy.
