So in this situation I would say you wildly misjudged who your customer actually was. Because the people you're talking to aren't your customer and they aren't even potential customers. We can know this fact because they don't have any decision making power and they are also not in a position where they believe they could even recommend a product to their management.
If you believe that you have a viable product that solves a problem in the industry and it is good enough to present to someone you presented to the management directly. The key thing is getting your thing in front of decision makers and having it be something the decision makers can understand. This may mean you need a bit more polish or you may need to collaborate with someone who is better at sales and marketing. That's really your next step if you have something that you believe will solve a problem. Alternatively you could reach out to more technical people who are comfortable bringing this up to their management chain and getting it in front of real decision makers.
