This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS .
It gets ~80K MAUs and just slowly and consistently is growing organically through word of mouth through history focused communities. I'm currently playing with expanding the coverage internationally as I still only support the US which is a wickedly fun project.
