For people who built their own app, often with AI
Your app works. I keep it working.
People use your app, but it isn't ready for production yet. I put it in the stores and keep it running. The agents do the work, I sign off.

How it starts
First an intake. It's free.
Before you pay anything, you know what your app will cost and whether I'll take it over. On average that takes 1 to 2 weeks. A bit longer for a big app.
Soon you'll register through the Appfabriek app. Want a message when it's here?
01You register your appThrough the Appfabriek app. I schedule the intake as soon as I can.
02The agents examine your appThey estimate what infra, maintenance, support and new features will cost. That research costs next to nothing, so I don't charge for it.
03We talk it throughI go through the estimate with you. What's needed, what it costs, what could be better.
04I decideIf it's feasible, I take your app over. If not, I say no and tell you why.
The line
What happens to your app
Five steps, tracked per app. The agents do the work and report what they did. Anything that can't be undone comes past me first.
- 01Take overYour code goes into your own repo. The agents close security holes and write tests.
- 02TestNothing goes through without tests and a test report.
- 03 · SIGN-OFFI sign offProduction, money and outside messages wait for my sign-off.
- 04ReleaseIn the App Store and Google Play, including reviews and updates.
- 05Run and supportOn EU servers. Maintenance and support for your users.

What it costs
All costs plus 1%
You pay what your app really costs: development, infra and support. The agents do the work, so that's a fraction of what you're used to. I add 1% on top. That's my margin. Every month you get an overview of the running costs.
Why so little? The groundwork is already built.Domain, site, sign-in, backups and monitoring are in Dok. Chat, calls and appointments are in Casco. I only build what makes your app yours.
