Markus Aicheler is a deep tech entrepreneur based in Geneva. He built a scientific foundation over fifteen years at CERN and the University of Helsinki, where he led the Accelerator Technology Project. In 2022 he co-founded SolidWatts, leading it as CEO for nearly four years and raising over €4 million, and has served as CTO since January 2026. His work focuses on electrifying industrial heat. According to the European Commission, 80% of industrial thermal uses are technically electrifiable but only 3% currently are — one of the largest unaddressed decarbonisation opportunities in industry. SolidWatts fills that gap with scalable high-power microwave heating for heavy and process industries.
