## About

Based in Gumligen, Switzerland, and founded in 2018 by Jürg Jost (CTO), Spacetek Technology AG focuses on the production of time-of-flight mass spectrometers that use an analytical technique to characterize the chemical composition of gaseous, liquid, and solid samples. As of 2024, the company is led by its CEO, Maximilian Rothenberger. In November 2025, Spacetek Technology AG raised a total of CHF 9.6 million in venture and debt funding from Technology Fund and UBS.

The company’s product line includes the IonTamer Series, a time-of-flight residual gas analyzer that monitors the composition of gases in real-time, at high resolution, and with excellent sensitivity. The IonTamer Series includes IonTamer DI, which comprises an analyzer, as well as all necessary electronics and software; IonTamer FA, which consists of an analyzer in a vacuum chamber with a pressure gauge, as well as all necessary electronics and software; and IonTamer PS. The IonTamer Series is used across a wide range of areas, including wafer manufacturing for process control, OLED-display manufacturing for contamination control, environmental science research for field analysis, and industrial vacuum coating for process optimization.

The company plans to utilize the November 2025 funding to speed up international rollouts, enhance its technology development plans, and foster expansion in both semiconductor and space sectors.
