Building Donza.
Two decades of engineering -
pointed at one problem.
I'm Patrick. I spent twenty years in regulated MedTech - engineering medical-imaging software, leading global quality operations, auditing against the very standards I helped write. In 2026 I'm founding Donza: a family admin platform for DACH parents that dissolves the invisible mental load of school-age family life.
Donza is in active development. This site is the case for why I'm the right person to build it.
Proving I can ship. Then betting on the one that matters.
For a decade I kept hitting real problems and thinking “if only an app existed for this.” Modern AI changed the equation, so I ran a deliberate build sprint: each app pressure-testing a different layer of the stack, the whole thing R&D to master the method before committing to Donza.
The output: a unified stack I can ship, iterate and scale on - and the judgment to know which problem is worth turning into a company.

Donza
🔧 In development · Pre-launchDonza is an AI-powered family admin platform for DACH parents. It captures the chaos of school-age family life - forwarded emails, photographed letters, pasted WhatsApp messages - extracts what matters, and handles the next step automatically: RSVP drafts, exam reminders, morning briefs, village delegation.
Current stage: Families are using it daily; the next step is public launch - and I'm open to funding and partners to get there faster.
The market is large (3.4M DACH households in the serviceable segment), the problem is real and lived, and the technical foundation is privacy-first, built with the discipline of regulated software. Everything I've built points here.
