## About

Aton was founded in 2001 by physician-entrepreneur Dr. Lutz Helmig. The firm manages proceeds from the 2001 sale of Helios Kliniken, the hospital chain he created. Ownership is split among family members, with Dr. Helmig holding 60 percent. The office deploys capital through direct equity positions and infrastructure holdings. Confirmed focuses include ClimateTech, Energy Transition & Renewables, Digital Health, Industrial Tech and SpaceTech. Investments target Europe. Positions are held in operating businesses that show established market traction and sustainable growth profiles. The firm also maintains real-asset exposure through commercial properties in Munich and aircraft operated via DC Aviation. Aton lists 2,527 million USD under management on internal records. The team operates from a single headquarters at Prinzregentenstraße 18 in Munich. Additional family assets include the Villa am Frauenberg in Fulda and a classic-car collection. No new leadership changes or capital raises were recorded in the last 24 months. Ownership remains concentrated within the Helmig family.
