Talk to people you think would be your ideal user. Worst case scenario they say no.
I built it for the ideal user, I have a second one that is a luke-warm lead in the pipeline but currently getting screwed by a vendor who shall remain nameless. The problem is, these sub-par vendors have been around and have strong marketing, I have no marketing, and we both know marketing is what gets people's attention first.
I actually have one system integrator for the product this connects to interested, and I'd love to get more of them on board with it and selling it to their customers as well.
Proactively looking for and contacting possible customers and building a feedback cycle and improving your product and how you pitch it will give you a chance to turn it into a business or company or whatever your ambitions are.
My plan however is to get on some focused groups, for example, LinkedIn SAP groups and try to find some system integrators to talk to there.
Your problem description is vague but it sounds like you're saying in this comment that you are looking at evidence that in this market you either need to get a strong salesperson or be a strong salesperson, but currently aren't making either of those happen.
a) I don't have a working budget for design work, branding, or sales staff
b) Some folks around here have been there before too, and found a way over the bootstrapping hump, I'm curious how.
My question is poorly-worded. It was written at a moment when I was frustrated, but I was hoping for a good story from someone about how they got past the stage where you don't have the capital to commit to scaling the business up but you have good tools ready.
And the marketing question was because it looked like that you say that the marketing part actually is okay, the product and message fits the market, but your direct sales activities (i.e., the actual closing the deals/"make them sign on the dotted line finally" activity which is probably the only part of customer relations that's not usually called marketing) are lagging.
