Meet us.

Continuously we are learning more. We visit conferences, meetups and bar camps. Will you be on one of the upcoming conferences, too? We would love to meet you.

How we work.


Reliability and high quality are our most important goals. That's why we work with clearly defined processes, not only when we work with code. Every potential client or partner receives a detailed offer and an order confirmation before the project starts. We always work agile – sprint-based with Scrum or with various releases with Kanban. Besides that we care about privacy and data security.

Nobody's perfect. That's why we established a continous improvement process, so we can build on our experiences and improve the quality of our work constantly. Our method reflects in our general terms and conditions, The Geil,Danke! Reliability Manifesto. You can read the Manifesto in a new tab here (german version).


Our high expectations in reliability and quality are reflected in our development process. We focus on maintainability to allow a project to grow. We emphasize clean code, clearly defined code-conventions and a good documenation.

We work with established build and deployment processes, test-driven development and contiuous integration. We fix bugs before implementing new features. And we foster data and code cleansing methods.


Whenever we work on products and projects, we improve the usability. To design and implement an outstanding user experience is our primary motive.

We work design-driven and continuously increase our knowledge. Advanced trainings and the exploration of new technologies are the foundation for our consulting services, workshops, talks and UX design assignments.
