Neustark was founded in 2019 by Johannes Tiefenthaler and Valentin Gutknecht as an ETH Zurich spin-off. The two young entrepreneurs came together based on their shared vision of a solution for the utilization and storage of CO₂. In 2020, neustark’s first pilot plant was integrated into the production line of an established concrete producer. Today, various concrete producers store CO₂ with one of neustark’s mobile plants and produce concrete that is used both in private and public construction projects.
