Hi! We are Friedemann and Josua, ExoMatter’s scientific experts. Both of us are materials scientists with a passion for driving value from data.

We have 10+ years of combined experience as researchers and science coordinators (DLR, Berkeley Lab, Celonis). Our scientific publications reached a total of 1000+ citations.

We implement your materials research projects.

The team is based in Germany (Munich and Cologne).
We are happy to get in touch with you via e-mail or LinkedIn!

supported by the Helmholtz Association

We are commercializing technology from research and making it available to a broad industrial audience. Through pilot projects in collaboration with industry partners, we explore the business value and usability of our technology.
