Ok, you have hit the reality of most startup enthusiasts. Most of us when starting are without much connections and of course no big marketing budgets. How to go from here? If you truly believe it solves a real problem, then proceed. First we need some customers and serve them individually on this tool. One customer at a time; each one will give you amazing joy because you were giving up on it. One nice way for this is to search for jobs/projects on freelancing sites like Upwork, that are looking to "build me tool that takes excel file as input and let me do this and that", something like that. Pitch them that you can do it for fraction of the price with an existing tool you've built. It's time consuming, because you'll bid and may not here from many, but you can see those are real customers with problems looking for similar solutions. I built https://ASPSecurityKit.net https://ASPSecurityKit.net v1 back in 2013, after I saw a project on upwork asking to build user registration/management workflow. I already had pieces of it figured out in my client projects, but there was no impulse to package it up and offer it as an independent product. I built a pre-launch page, talking about what I'M going to build and collected 70 odd emails from HN folks, thinking some of them will buy upon launch. Worked hard for 1.5 months on coding, packaging, docs etc. and launched but nobody bought from that email list or HN right away. I was in a job then (at Microsoft) and didn't spend much time on marketing after launch as nobody bought. 1st month: nothing. 2nd month: nothing. Latter half of the 3rd month: first sale while I was on a sort of vacation/WFH!
