Your financial guardian for the Netherlands
Bowie exists because navigating Dutch finances shouldn't require a law degree. We build intelligent tools that scan, calculate, and protect — so you keep what's rightfully yours.
Nobody should overpay because the system is complex
The Netherlands has world-class public services — but an equally complex financial system. Rent regulations with 100+ variables. A wealth tax that was ruled unconstitutional. Benefits that millions of people miss every year. Bowie was built to fix that gap. Not by replacing professionals, but by giving everyone instant, accurate insight into their financial situation — for free.

One app that guards all your finances
Today, Bowie checks your rent and calculates your Box 3 tax. Tomorrow, it will optimise your benefits, generate legal letters, file objections, and alert you when something changes. The endgame is simple: Bowie watches your back on everything financial in the Netherlands — automatically, privately, and in your language.
Scan
Bowie scans your situation across rent, taxes, and benefits to find where you're losing money.
Calculate
Precise calculations based on the latest Dutch law — from WWS points to Box 3 rendement to toeslagen eligibility.
Protect
Actionable next steps: letters, objections, and guidance through official processes like the Huurcommissie.
Principles, not just features
Privacy by design
Your financial data never leaves your browser. All calculations run client-side. We can't see your numbers — and that's by design.
EU-first infrastructure
Everything is hosted in Frankfurt, Germany. No data leaves the EU. We're GDPR-compliant from day one, not as an afterthought.
Accuracy over speed
Our calculations are based on published legal formulas, official forfait percentages, and actual court rulings. We verify every number.
Built for everyone
Whether you're a Dutch native or an expat who just moved to Amsterdam — Bowie speaks your language and explains the system in terms you understand.
Free where it matters
The core tools will always be free. Everyone deserves to know if they're being overcharged, regardless of what they can afford to pay.
Open about limitations
Bowie gives you indicative results, not legal advice. We tell you clearly when to consult a professional — because trust is earned through honesty.
