Product engineering studio
Feinwerk Software designs and builds web platforms, AI systems and cloud infrastructure for businesses in Europe and Asia. Every engagement starts with a defined scope, a fixed or custom price and a committed delivery date, and we keep maintaining what we build after launch.

How it works
One call, a written plan, weekly demos, then a launch you can put in the calendar, and a team that keeps maintaining it afterwards. You stay in control the whole way.
Day 1
Tell us what has to exist
A 30-minute call. Walk us through the product, the users and the deadline. Within five working days you will have a written scope, a fixed price for a standard plan or a custom quote, and a launch date.
- Written scope
- Fixed or custom quote
- Launch date
Every Friday
Watch it get built
A working version you can click on every Friday, with a short written update. Change your mind early and it costs nothing.
- Weekly demo
- Staging access
- Written update
Launch day and after
Launch, and we stay
We ship, monitor it live, fix what breaks and keep maintaining it. We do not hand over and disappear: stay on a maintenance plan for updates and support, or take it in-house with full documentation. Yours either way.
- Monitoring
- Maintenance & support
- Full handover
One call. Five working days to a fixed or custom quote and a launch date. Maintained after launch.
Client voices
Every quote sits next to the project it describes, so you can check the claim against the work.
Read the projects“Every shilling on the platform has to reconcile, and it does. Feinwerk built the wallet, the rent distribution and the resale market so that nothing rounds in our favour and nothing moves without an admin seeing it. That is exactly the level of care a members club handling real money needs.”
