Markus Fuhrmann co-founded the food delivery service Lieferheld, which became part of Delivery Hero. In 2019 he co-founded Gropyus with Philipp Erler and Bernd Oswald. The plan was to build timber apartments in a factory, with robots, and to design them on a digital platform.
Vonovia, Germany's largest landlord, put in €100 million in January 2023, about €100 million in October 2024 and €100 million in March 2026. Its subsidiary Buwog came to hold about 25%. Total equity raised passed €400 million. The group employed about 550 people across Vienna, Berlin, Richen and Steinhaus.
Parent company revenue fell from €11.2 million in 2024 to €7.9 million in 2025. The operating loss narrowed from €23.6 million to €12.9 million. The company named high construction and financing costs and slow approvals as the main pressures.
In August 2026 Fuhrmann moved from CEO to the supervisory board. On 3 November 2026 several Gropyus subsidiaries filed for insolvency after an expected investor payment did not arrive.
