greenteg Accelerates Global Expansion With New Investors on Board


greenteg AG (Switzerland) started in 2009 as an ETH Zurich Spinoff and focuses on the development, manufacturing, and global sales of heatflux sensors for applications ranging from photonics, building insulation, and battery characterization to core body temperature measurement in the form factor of wearables. CORE, its Performance Sports Wearable brand launched in 2020 and having since received significant recognition, making the headlines being used by the 1st and 3rd ranked 2022 Ironman Hawaii winners and the Hour Record of cyclist Filippo Ganna.

Existing and new investors have invested a total of CHF 10 million in order to accelerate global expansion of greenteg’s business. With the proceeds from this round greenteg not only will invest strongly into R&D for medical applications in the wearable market, but also to further scale its production capacity in Rümlang (Zurich) by a factor of 10 already in 2023. In the coming years greenteg plans to ship tens of millions of its unique heatflux sensors to wearable customers around the globe. At this strategically important growth stage greenteg also gained three new Board Members with Gilbert Achermann, Peter Germann and Felix Haldner. They bring decades of relevant entrepreneurial and industry experience to the team and have scaled companies to global leaders in the past.

Wulf Glatz, greenteg’s Co-founder and CEO, is enthusiastic about the quantum leap of the company: “Over the past year, we have seen a tremendous increase of interest in our caleragt solution for non-invasive and continuous monitoring of core body temperature. Solution providers for work safety as well as manufacturers of medical and consumer wearables have been desperately looking for a viable solution. We enable healthcare professionals, patients, and workers with an easy-to-use and safe experience in monitoring this important vital parameter. We are extremely happy to have attracted renowned experts in our target markets as new investors and Board Members.”
