When you don't have a thing to show a potential customer, it is kinda putting it on them to figure out how what you are asking about can best be useful to them. Seems like it might not be too fruitful.

If you build it, will they come?

I understand the duality. On the one hand, you need to have a product to show the customer. In situation 2, you don't have a product to show the customer. Conducting market research before developing a product is crucial, but sometimes these studies don't tell you much about new and innovative products. I believe that we should have something to show the customer, and if there is interest, then we can continue with the development. I'm not an expert in this matter, but it's what I see my boss do, and he's relatively successful.
