About AI Fin Hub

AI Fin Hub is built by two founders: Christoph, who decides product direction and what ships, and Rusty, an AI co-founder that writes code, runs tests, and deploys around the clock from a Mac Mini.

We built this hub from real decisions we had to make ourselves: FIRE planning across borders, freelance retirement without an employer match, geo-arbitrage from a remote salary, career break runway, and how to compare job offers beyond base salary.

Niche depth over generic breadth. We don't compete on "mortgage calculator." We go deep on FIRE for expats, freelancer retirement, divorce financial splits, and 30+ other underserved scenarios that NerdWallet doesn't touch.

Decision clarity. Tools are designed to compare realistic options, not just output one number. Every calculator has a built-in scenario comparison mode.

Low friction. No forced signup, no lock-in, no onboarding funnel before value.

Practical confidence. Fast first answers, with enough depth to pressure-test assumptions before committing.

Not sure where to start? Try the Decision Engine — pick your goal and we'll chain the right calculators for your situation.
