datavisyn was founded by four leading scientists in the field of visual data science for biomedical informatics.

Marc, Sam, Alex, and Nils have collaborated on dozens of research papers and released many open-source software packages for biomedical data analysis in their capacity as professors and researchers at JKU Linz, the University of Utah, and Harvard University. While we love research and remain committed to open source, we created datavisyn to make the latest scientific and technological advances available to commercial entities and provide services – such as data integration and custom solutions – that are not possible in an academic context.

Team Statements

I am a Lead UX Engineer at datavisyn and I really enjoy working here. I especially like the team spirit—everybody supports each other at all levels. My daily work is diverse as it includes front-end and back-end development as well as UI and UX tasks. I’m very happy to contribute to different customer and research projects where I can apply and further develop my knowledge and skills.


I’m Lead Scientist & Software Engineer at datavisyn. I enjoy it because of the diversity of my tasks—every day is different. On the one hand, I collaborate with other researchers from academia on projects to create new visualization and visual analytics approaches that can improve our products in a later stage. On the other hand, I develop and tailor the Ordino product together with my colleagues for our customers’ success. I also like that we can use the latest technologies to build and deliver web-based visualizations and that I can work with great people in house and around the world.
