You have the idea.
I build the first version.

The first version of your product that does only what is necessary, but does it properly. Real users work with it, and you learn what comes next before you invest more.

For simple ideas that works, and then you should. It gets hard with login and permissions, payments, data protection and operations. That is where self-built apps often stall. I use the same AI tools, with experience since 2014 and at a fixed price. A clickable prototype from Lovable and co. is a good start for the workshop. Whether we build on its code or use it as a template for a clean rebuild, we decide after a look at its state. If your app already runs with real users, the app check shows what is missing before launch.

Yes. I work with founders and companies in Germany, Austria and Switzerland, remotely and in German.

Between €10,000 and €50,000, depending on the scope. The three examples above help you place your project. The exact fixed price comes out of the spec workshop.

Two sessions of two hours each, by video. The people who decide should be there, and if possible someone who knows the future users well. We sort your ideas and define what the first version needs and what can wait. You get a prioritized feature list, the architecture and, within three business days after the second session, a fixed price. Book the MVP, and half the workshop fee is credited. The workshop is also available on its own: with the result, you decide yourself who builds the first version.

The workshop on order. The MVP by milestone: each one half at the start and half after acceptance, for which you have five business days. Half the workshop fee is credited on the first invoice.

The build takes four to eight weeks, depending on the scope. I can usually start two to four weeks after the order.

That happens with every MVP. Swapping a feature for one of the same size costs nothing extra. Anything bigger gets its own fixed price or goes into the next version. The agreed price stays stable.

A standard stack: Next.js and TypeScript, with Node.js and Fastify on the backend, and usually PostgreSQL as the database. Depending on the project another one, for example MySQL. Widely used, well documented and easy to hand over. I build web apps that run in the browser, on the phone just as on the desktop. Apps for the app stores are not part of it.

Yes. If you want, it runs in your infrastructure, for example in Azure, AWS or on your own servers. Login can run through your existing company account, for example via Microsoft login (single sign-on).

Hosting, database and email sending usually cost less than €100 per month at the start. The contracts are in your name, with no markup. I give you the exact costs in the workshop.

Optional maintenance from €1,000 per month at a fixed monthly price: 10 hours for updates, monitoring and small features. Or your own team takes over, with full documentation. Larger extensions are planned like the MVP, with their own fixed price.
