You have the idea.
I build the first version.
For founders and companies in Germany, Austria and Switzerland. From a sketch to a product real users can work with. Fixed price, in four to eight weeks.
Two sessions.
One clear scope.
Two times two hours. We sort the ideas and decide what the first version really needs. €1,200 to €1,800.
A plan you can rely on.
And one fixed price.
You get a prioritized feature list, the architecture and a fixed price for the build. No hourly estimate that keeps growing.
Weeks, not months.
Visible every step.
A preview for every feature, a demo every one to two weeks. AI does the heavy lifting, experience since 2014 keeps it right. That is why it is fast and still holds.
Your MVP is live.
Ready for real users.
Tested, documented and yours from day one. Code, repos and accounts are in your name.
Two kinds of clients. One way of working.
Founders
You want to put an idea in front of real users. Without building a team first, and without a year of development.
Business units
Your department needs its own tool and has a budget for a first version. You get a working product and a clean handover to your IT.

Code, repos, hosting and domain accounts are yours from day one. A standard stack (Next.js, TypeScript). Documentation is a fixed deliverable: README, architecture overview, decision log, runbook.
ProofHandover session and a recorded code walkthrough, included in the fixed price.
Good questions. Straight answers.
What does an MVP cost?
Between €15,000 and €35,000, depending on the scope. The exact fixed price comes out of the spec workshop.
What happens in the spec workshop?
Two sessions of two hours each. We sort your ideas and define what the first version needs and what can wait. You get a prioritized feature list, the architecture and a fixed price.
How long does it take?
Four to eight weeks after the workshop, depending on the scope.
Which technology do you use?
A standard stack: Next.js and TypeScript, with Node.js and Fastify on the backend. Widely used, well documented and easy to hand over.
What happens after launch?
Optional maintenance from €1,200 per month at a fixed monthly price: updates, monitoring and small features within an agreed scope. Or your own team takes over, with full documentation.
Who owns the code?
You do, from day one. Code, repos and accounts are in your name.
Do you work with clients in Austria and Switzerland?
Yes. I work with founders and companies in Germany, Austria and Switzerland, remotely and in German.
Let’s shape your idea.
Into a first version.
Start with the spec workshop. Two sessions, a clear scope, a fixed price. Then you decide.
