Since 2015
Our Story.
Martin and Joachim have been working on digital product ideas together since 2015. That collaboration shaped their approach: bringing design and software development together from the start.
Today, we combine custom client projects with our own products. Taxora and stemplr serve businesses; Mostly and Gugu bring weather information and personalised stories into everyday life. Building our own products also informs the architecture, design and operation of our client solutions.
Our roots are in Austria, with a location in Riegersburg and a US presence in New York. The LLC was founded in 2022 and the Austrian FlexKapG in 2024. Our projects bring engineering, design and direct team collaboration together.
Our Vision.
We want to build software that people can rely on in everyday work and life. Usability, technical structure and ongoing operation need to work together. We plan them together and improve solutions based on how they are used.
Research-Driven
We test assumptions through research, prototypes and clear evaluation before committing to larger development steps.
Sustainable Thinking
We focus on maintainable structures, appropriate infrastructure and reusable components.
Human Focus
We design workflows so people understand the next steps and can follow important decisions.
