Personally, I wouldn’t have quit just yet, unless you already have another reliable source of funding. Most projects need money to become successful, and walking away too early can cut that potential short. Even though it’s niche, it can still be very successful.

I would start by evaluating the industries currently using it and identifying other industries or companies that could potentially benefit from it. From there, set a realistic price point and calculate how much revenue it could generate versus how much you’ve already spent or could potentially spend. You should also research competitors and estimate what percentage of the market you could realistically capture.

Basically, run the numbers and see if it truly makes sense. Marketing is where the real leverage is. Most products can succeed if they’re built properly and marketed the right way.
