About us
We have been developing and operating web-based applications for 25 years. We work directly with clients and as a technical partner to agencies – for businesses, public sector organisations and associations.
Skills
We design, develop and operate web applications based on TYPO3, Shopware and Node. Our strength lies in translating individual requirements into software that works in day-to-day use and remains maintainable in the long term.
We particularly enjoy working on projects where multiple systems interact, where bespoke requirements need to be implemented, or where off-the-shelf software reaches its limits.

Our values
Digital sovereignty
We firmly believe that businesses should retain control over their digital infrastructure. That is why we prioritise open standards, open-source technologies and EU-based hosting.
Our aim is to reduce dependence on individual manufacturers, platforms or service providers and to ensure you retain long-term freedom of choice. Where proprietary systems form part of your IT landscape, we integrate them via standardised APIs and open interfaces.
For us, digital sovereignty means transparency, control and future-proofing – both in the solutions we develop for our clients and in our own infrastructure.
Responsibility
Software is more than just a project. It must function reliably, be operated securely and remain maintainable in the long term.
That is why we place great emphasis on quality, security and performance. We don’t just think as far as the go-live; we take responsibility for the solutions we develop.
And if something unexpected does happen, we won’t leave you to sort it out on your own. When it really matters, we support our clients even outside normal business hours.
Partnership
Successful projects are the result of a trusting working relationship. That is why we do not see ourselves merely as a service provider, but as a long-term partner at your side.
We offer honest advice, communicate transparently and address challenges at an early stage. Our aim is not to sell you as many services as possible, but to implement the solution that is right for you. You can rest assured that we always make decisions in the best interests of your company and are fully committed to achieving your goals.
How we use AI
We make productive use of the latest AI tools in development – under conditions that we define and control. Permissions are enforced via the infrastructure, customer data remains outside the AI sandboxes, and a human always makes the final decision at critical junctures.
The responsibility remains with us: we formulate the requirements, define secure environments, make the architectural decisions and meticulously review the generated code.
For you, this means better quality at a lower price. What AI will not change: our staff and our personal relationships with customers.
