Gropyus secures €100M to factory-build Europe's missing homes
Vienna-based proptech startup Gropyus has closed a €100 million growth round, its third nine-figure raise. With total equity now exceeding €400 million — plus €40 million in European Investment Bank venture debt — the company will expand its robotic factory and fund technology R&D.
Founded in 2019 by Delivery Hero co-founder Markus Fuhrmann and former Zalando exec Philipp Erler , Gropyus uses a fully robotic smart factory to pre-produce timber-hybrid walls and ceilings for multistory residential buildings. Its factory in Richen, near Heilbronn, runs 50 KUKA robots and achieves 86% automation, turning out building components in roughly 16 minutes.
Europe's housing shortage is acute. Costs are rising, build times are long, and skilled labour is scarce — structural problems that conventional construction cannot solve quickly. Gropyus claims its method cuts build times by 30–50% and lowers both cost and emissions versus traditional on-site construction.
The new capital will allow the company to scale from one production shift to three, targeting 250,000 m² of output per year. Profitability is expected by 2027–28. A pilot project — 68 units in Salzburg with construction firm Rhomberg Bau — is set for delivery in 2026.
The prefab and modular construction space has a troubled track record. US rival Katerra raised over $2 billion and collapsed in 2021, unable to make factory-built housing economically viable at scale.
Gropyus must prove it can run multiple projects in parallel, manage supply chains across EU markets, and hit its margin targets — all before its runway runs out.
Gropyus is betting that housing can be industrialised the way Tesla industrialised cars — high automation, mass customisation, and predictable output.
As European governments scramble to close housing deficits, capital is flowing to startups that promise to build faster and cheaper. If Gropyus can deliver, it points to a future where homes are manufactured, not built — and where the construction site becomes a place of assembly, not production.
