I am working on https://firedating.me - a dating site for FIRE (Financial Independence / Early Retirement) enthusiasts. One can also look for friends there. The stats are public: https://firedating.me/open The site is 100% free and even ad-free. It is my hobby project and I just enjoy helping others, meeting interesting people and learning while developing it. Looks like loneliness is widespread in the FIRE community…
Gold digger heaven, here I come! Seriously cool idea, sounds like fun and it might be quite refreshing for the fire-folks to talk to like-minded people, it can be hard not to talk about your passion too much.
My impression is that FIRE folks are not that good of target. But I understand that this could become more of a problem when the site grows and I have couple ideas how I could tackle it then.
