Built a full-stack finance companion app in just 12 hours using AI-assisted development. Solo founder move, zero external help needed.

The app targets $25K monthly recurring revenue within 90 days. Unit economics look solid—pricing sits at $8–12 per user monthly with freemium entry, and early modeling shows a 6.4x LTV to CAC ratio when combining paid acquisition with organic growth channels.

The tech stack leans privacy-first and offline-capable. Users can access core features without constant internet, and all data handling follows a strict zero-knowledge architecture. Clean UI, minimal friction, designed for actual daily use rather than feature bloat.

It's the kind of lean build that proves you don't need massive teams or funding to ship something genuinely useful in fintech.
