The only way something like this would work is through "networking", and trust that you are capable of delivering.

I'm practical terms, go to where the decision makers are and shmooz with them. It's a numbers game. Eventually someone will say yes.

That's what it means to be a "people person" in the context of trying to sell a product, yes. Getting within 2 degrees of a decision maker can open up millions for you, while being a rounding error for every company you work with.
