About us

Professional software engineers with 15+ years of experience.

15+years

We prototype, maintain, scale and polish your software. One team takes it from the first idea to a tool your company relies on every day.

01

Prototype

A working first version on your real data, fast.

02

Maintain

Fixes, updates and backups, so the tool keeps running.

03

Scale

More users, locations and data without slowing down.

04

Polish

Design, speed and details your team will notice.

How we work

Four phases, each with a clear price and deadline.

01 · 1 week

Discovery

We visit or meet online and learn your work: who does what, where time gets lost, what data you already have.

02 · 3 weeks

Prototype

We build the tool on your real data. Every week you see what works, and we change course while it is still cheap.

03 · monthly

Service

Fixes, small changes, backups and hosting for a fixed monthly fee. The tool does not stop when a developer leaves.

04 · as needed

Growth and polish

More users, new locations, a mobile version, reports for management. When your company grows, the tool grows with it.

Packages

You pay for results, not hours.

Classic custom app development takes months and costs tens of thousands of euros. We work with AI tools and proven building blocks, so the first version arrives in four weeks at a fixed price.
