Munich-based
construction robotics startup Sitegeist has raised €4 million in a pre-seed
funding round co-led by b2venture and OpenOcean, with participation from
UnternehmerTUM Funding for Innovators and several angel investors, including
Verena Pausder, Lea-Sophie Cramer, Alexander Schwörer, and additional strategic
backers from the construction and robotics sectors.
Across
Europe, ageing bridges, tunnels, parking facilities, and public buildings
require major renovation. In Germany alone, the repair backlog amounts to
hundreds of billions of euros, with similar challenges seen in North America
and other regions. Labour shortages and the physically demanding nature of
concrete repair make projects costly, hard to staff, and difficult to scale.
Concrete renovation is particularly complex and capacity-constrained. Removing
deteriorated concrete using high-pressure water or abrasive blasting requires
precision and close supervision to avoid damaging steel reinforcement. Because
the process is largely manual and site-specific, construction companies often
face low efficiency, rising safety demands, and significant project backlogs.
Sitegeist
aims to address these challenges with modular automated robots designed for
unstructured construction environments. Unlike conventional automation systems
that rely on pre-existing 3D models or standardised site conditions, the
company’s robotic systems are built to operate directly on existing structures.
Using advanced sensing, AI-based decision support, and adaptive control, they
can handle complex geometries and varying material conditions without prior
digitisation, enabling deployment on active renovation sites.
Building
on this approach, Dr Lena-Marie Pätzmann, co-founder and CEO of Sitegeist,
said that infrastructure renovation, particularly concrete repair, is facing
a major bottleneck. She explained that deteriorated concrete is still removed
through labour-intensive methods that are difficult to scale, and that Sitegeist
is addressing this challenge by developing specialised, modular automated
robots capable of performing renovation tasks directly on existing structures.
The
company works closely with concrete renovation firms on-site and is developing
a modular platform intended to expand across the renovation value chain over
time. Looking forward, Sitegeist plans to collaborate with additional test sites,
co-development partners, and new talent to further validate and refine its
robotic systems.
The new
funding will support team expansion and accelerate the deployment of
Sitegeist’s automated, AI-enabled robots on real-world construction sites,
helping concrete renovation companies address ongoing capacity constraints.
