Personal finance for people living between countries.
The problem.
Managing money across currencies is genuinely difficult. Exchange rates shift. Accounts multiply. Local obligations do not pause because you have moved countries. Most finance apps are built for one country, one currency, one life that stays put. Expats and internationally mobile professionals have always made do with tools that were not built for them.
What we built.
A privacy-first personal finance platform for people living and earning across borders. Web application, iOS, and Android. A single product across all three, built and maintained by the same team that designed it. No outsourced mobile. No feature gaps between platforms. Multi-currency at the core. Not bolted on. Every financial view, every calculation, every export works natively across currencies from the ground up.
How we built it.
React Native for mobile. Next.js for web. FastAPI on the backend. Supabase for auth. Paddle for billing. A monorepo that keeps all three platforms in sync. Privacy-first architecture from day one. User data collected minimally. Stored securely. Never sold. GDPR-compliant. Not because a lawyer reviewed it at the end, but because the decisions were made at the beginning.
