Custom software development: software that fits your business

We build web apps, platforms and customer portals for mid-sized and growing companies. Concept, UX/UI design and development from one team in Leipzig. Over 200 projects, 5.0 stars on Google and OMR Reviews.

Standard software ends where your process begins.

Custom software isn't worth it for everyone. It pays off when your workflow is special, when standard tools slow you down, or when license costs grow faster than your team.

How your software project runs with us

No blind flight, no surprises on price. Four steps, and after each one you know where you stand.

01

Vision Sprint

2 weeks

In two weeks we analyze your process, show you three design concepts and a user flow, and give you an honest effort estimate. €1,499, credited when you commission the project.

02

Concept and UX/UI design

3 to 4 weeks

We build a clickable prototype your team tests before the first line of code. What doesn't work here won't need an expensive rebuild later.

03

Development in sprints

3 to 6 months

React, Next.js, React Native and Node.js. A demo with real features every two weeks, not a status report. You see progress, not slides.

04

Launch and further development

ongoing

We take the software live, run it and keep developing it with predictable hour packages. The code is yours from day one.

What you get in writing

Four commitments that are in the contract, not just on the website.

  • The agreed price is the final price

    After the workshop there is a fixed price. Change requests are quoted in advance, never billed afterwards.

  • Code, design and accounts belong to you

    Repository, Figma files, Webflow or hosting account run under your name. You can continue without us at any time.

  • We'll also tell you what you don't need

    If the Vision Sprint shows that an app or software makes no sense, we say so. The sprint result is yours; you don't have to continue.

  • A reply within one business day

    Management reads every inquiry personally. You get an answer within one business day, not a ticket.

Frequently asked questions about custom software development

The questions managing directors and product owners ask us most often in the first conversation.

What does custom software development cost?

It depends on the scope, which is why we start with the Vision Sprint for €1,499. After that you get a fixed price. Most first production versions land between €30,000 and €100,000. Further development runs through hour packages from €2,699 per month.

How long does development take?

The Vision Sprint takes two weeks. Depending on scope, we deliver a first production version after three to six months. You see a demo with real features every two weeks.

Who owns the code?

You do. You receive the complete source code, the documentation and all access. You can continue with another team at any time – even if we hope you won't.

Which technologies do you use?

Web apps and platforms with React and Next.js, mobile apps with React Native, backends with Node.js and PostgreSQL. Where it makes sense, we integrate AI features such as assistants or automated analysis.

What happens after launch?

We run the software, monitor it and keep developing it with predictable hour packages. You decide how much pace you want: 30, 60 or 120 hours per month.
