Sitegeist, a European construction robotics startup, has raised €4 million in pre-seed funding to modernize concrete renovation and address the growing infrastructure backlog across Europe. The round was co-led by b2venture and OpenOcean, with additional support from UnternehmerTUM Funding for Innovators. The company also secured backing from prominent industry and business leaders spanning construction, robotics, and entrepreneurship.

Founded by Dr. Lena-Marie Pätzmann, along with co-founders Nicola Kolb, Julian Hoffmann, and Claus Carste, Sitegeist is developing modular robotic systems to automate labor-intensive concrete renovation tasks performed directly on construction sites.

Across Europe, aging infrastructure has become an urgent challenge. Much of the continent’s concrete repair work remains manual, physically demanding, and difficult to scale efficiently. According to Sitegeist, this reliance on traditional methods has become a key bottleneck preventing cities from modernizing at the pace required.

The company aims to address this gap by introducing modular robots capable of handling some of the toughest on-site renovation jobs. By automating physically grueling tasks, Sitegeist intends to improve efficiency, enhance safety, and enable more scalable infrastructure renewal.

The funding round brings together deep technical and industry expertise. Venture firms b2venture and OpenOcean are known for backing early-stage technology startups across Europe, while UnternehmerTUM Funding for Innovators supports high-potential ventures emerging from Germany’s innovation ecosystem.

In addition to institutional investors, Sitegeist attracted support from established construction and business leaders, including Mario Wettengel and Alexander Schwoerer, as well as Verena Pausder, Lea-Sophie Cramer, Sven Degener, Andreas Kupke, and other strategic figures in construction and robotics.

Sitegeist plans to allocate €4 million to expand its engineering team and accelerate on-site pilot programs. The company said demand is rising as governments and private stakeholders move to address Europe’s large-scale infrastructure renovation backlog.

With early capital secured sooner than anticipated, Sitegeist is now focused on building what it describes as a world-class team of engineers and visionaries while rapidly scaling field deployments. The company is actively hiring as it prepares for its next phase of growth, positioning itself at the intersection of robotics and construction technology in a sector primed for transformation.
