Ask HN: How to learn to sell?
To be frank you've already committed the classic blunder of developer initiated startups.  You built before you sold.  Now there's no telling if what you built is what anyone wants.IMHO, and extrapolating a lot here it's very unlikely you will get any sale based off your MVP.  It's unlikely that you've hit the right market fit without first having found customer #1.So I'd back up a step and find someone with the problem you're trying to solve.  Offer the deal of a custom built solution to meet their need.  Once that's built and validated that it actually solves the problem then start selling to others.
