Munich-based construction robotics startup Sitegeist has secured €4 million in a pre-seed funding round to accelerate the rollout of its automated, AI-driven robots on construction sites.
The fresh capital will support rapid team expansion and the scaling of its modular robotics systems, designed to help concrete renovation companies address mounting capacity constraints across Europe.
The round was co-led by b2venture and OpenOcean, with participation from angel investors including Verena Pausder, Lea-Sophie Cramer and Alexander Schwörer, alongside strategic backers from the construction and robotics industries.
Addressing A Critical Infrastructure Bottleneck
Europe faces a growing backlog in infrastructure renovation, particularly in concrete repair. Many deteriorating structures are still maintained using labour-intensive, manual processes that are difficult to scale and increasingly constrained by skilled labour shortages.
Sitegeist, which emerged from the Technical University of Munich’s robotics institute under the leadership of Prof. Matthias Althoff, is developing specialised automated systems to tackle this challenge.
“Infrastructure renovation is hitting a critical bottleneck, especially in concrete repair,” said Dr. Lena-Marie Pätzmann, Co-founder and CEO of Sitegeist. “Deteriorated concrete is still removed using manual processes that are hard to scale. We’re building the first specialised automated and modular robots capable of performing concrete renovation directly on existing structures.”

Modular Robotics Built For Real-World Construction Sites
Founded by Dr. Lena-Marie Pätzmann, Julian Hoffmann, Nicola Kolb and Claus Carste, Sitegeist combines robotics engineering, AI expertise and operational experience to deliver a system tailored to complex construction environments.
The company’s robots use advanced sensors, AI-based decision-making and adaptive control systems to navigate irregular geometries and varying materials. Concrete removal is carried out using high-pressure water or abrasive blasting, while preserving the underlying steel reinforcement.
Designed with a modular architecture, the system can be deployed quickly and scaled as needed. It operates effectively on unstructured construction sites, even without digital building plans, aiming to deliver faster completion times, improved quality and reduced error rates.
Scaling Across Europe
With the new funding, Sitegeist plans to recruit specialised talent and expand field deployments, positioning its automated renovation systems as a response to Europe’s infrastructure renewal demands.
Founded in 2025, Sitegeist focuses initially on concrete renovation, with a broader vision of deploying autonomous, modular construction robots that address labour shortages and improve efficiency across the construction sector.
