About Us

Variolytics was created as a spin-off of the Fraunhofer IGB in Stuttgart. Our goal is to contribute to a more sustainable society by making the invisible visible. We achieve this through measurement technology that can be easily integrated into processes and enables measurements with a high data density and low measurement noise. With our high level of research and development expertise in process engineering and years of experience in the process industry, we support companies in an advisory capacity and in implementation. The latest methods of measurement data evaluation enable customers to generate entirely new business models and thus profitable new revenue potential.
