Crafting software for everyone

We are software engineers based in Berlin, Germany. We started working for startups, building minimal viable products and programming for startups in general. However, it turned out that the big players in the EU also appreciate our support and we are happy to provide software for everyone. We adhere to agile principles and are well equipped to handle almost any product complexity and develop well-tested software that performs as expected. We rely heavily on cutting-edge software development principles such as incremental and iterative release of software, rapid feedback, test-driven development, design and architecture modeling, and much more.
