01 / What we build
Custom software is software for one business instead of a whole market. We build it when the right thing can’t be bought off the shelf, or the off-the-shelf product doesn’t fit how you work. If something ready-made will do, we tell you in the intro call.
A system in the browser instead of the spreadsheet on the shared drive, with roles, login and audit log. Zularis, our CRM for vehicle registration services (Zulassungsdienste), has been running at a registration service in Duisburg-Hamborn since May 2026.
View Zularis ↗Tools only your team uses. For Dein Gutachter NRW we built one for Instagram posts: the AI suggests the text, a person checks it, and nothing is exported until the license plate has been checked on every photo.
View Dein Gutachter NRW ↗Data moves from one system to the next without anyone typing it in again. At Turkish Home, the prices in the shop come from the retailer’s POS system every morning.
View Turkish Home ↗When an application has to run on the office computer and not in the browser, we build it with C# and .NET.
For a client under NDA, a language model sorts incoming tickets. It writes no text. It only returns category, department and urgency.

03 / In person
Our office is at Jägerstraße 62A, 47166 Duisburg. If you’d rather talk at a table than on the phone, come by.
Before we build a system, we spend two days at your business and look at how the work gets done. That’s where the specification and the quote come from.
04 / What it costs
We bill by the hour. There’s no minimum project size, a small tool is a job too. The project assistant gives you a rough range in four questions, without you leaving any contact details.
Every payment comes after a sign-off. You can step out between any two milestones.
Cost estimate in four questions ↗05 / How it works
Up to the contract, we clarify whether we’re a fit for your project and what it costs. After that we build in one-week sprints, and at the end of each week you see a demo. The source code lives in your repository, the logins on your accounts.

The intro call costs nothing, and neither does the cost estimate after it. If what you need can be bought off the shelf, we tell you its name and send no invoice.
