Sitegeist & OpenOcean Target AI Robotics Expansion in Construction, 2026

LONDON, February 16, 2026 — Munich-based construction robotics startup Sitegeist has secured €4M in pre-seed funding to address Europe's concrete renovation labour shortage using AI-powered modular robots. The funding round was co-led by b2venture and OpenOcean, alongside prominent angel investors including Verena Pausder, Lea-Sophie Cramer, and Alexander Schwörer. The company aims to scale deployment of its autonomous robots to meet rising demand driven by a critical backlog in infrastructure repairs across the continent.

Executive Summary

• Sitegeist, a spinout from the Technical University of Munich, has raised €4M in pre-seed funding.
• The startup develops AI-enabled robots to automate concrete renovation processes.
• Key investors include b2venture, OpenOcean, and industry angels such as Verena Pausder.
• The funding will help expand the team, accelerate robot deployment, and explore new use cases.

Key Developments

Europe is grappling with a significant infrastructure repair backlog, with Germany alone facing costs in the hundreds of billions of euros. Labour shortages are exacerbating project delays and increasing costs in the concrete renovation sector. Sitegeist, founded by Dr. Lena-Marie Pätzmann, Julian Hoffmann, Nicola Kolb, and Claus Carste, seeks to address these challenges through robotics and AI innovation.

The startup's autonomous modular robots operate without prior 3D modelling or digitisation, enabling them to work on unstructured sites. Their advanced sensor systems, AI-driven decision-making, and adaptive controls allow for efficient concrete removal via high-pressure water or abrasive blasting. Unlike competitors such as RobCo and Brokk AB, Sitegeist’s platform is fully autonomous and designed for large-scale renovation projects.

Key benefits include modular scalability, faster project completion times, reduced rework, and compatibility with complex environments such as corners and columns. The new funding will be used to expand the team, grow test environments, and roll out robots with construction partners.

Market Context

The construction sector is facing a dual challenge: an ageing infrastructure base and acute labour shortages. Across Europe, delayed renovation projects are becoming a critical bottleneck, with bridges, tunnels, and parking structures requiring urgent attention. Traditional concrete removal methods are labour-intensive and costly, further straining resources.

Technological solutions such as robotics and AI offer a potential way forward. Companies like Brokk AB, Husqvarna AB, and Conjet AB have long dominated the market with semi-autonomous systems focused on surface-level tasks. However, Sitegeist’s fully autonomous robots represent a step-change in capability, promising efficiency gains in complex, unstructured environments.

BUSINESS 2.0 Analysis

Sitegeist’s €4M pre-seed funding comes at a pivotal moment for Europe's construction industry.

Labour shortages and rising costs are challenging the sector’s ability to address critical infrastructure needs. By leveraging AI and robotics, Sitegeist positions itself as a key player in this market, offering a scalable solution to meet demand.

One of Sitegeist’s most compelling differentiators is its ability to operate autonomously in unstructured environments without prior digitisation. This capability opens up opportunities in scenarios where conventional methods fail due to lack of precision or high costs. The modular nature of the robots also suggests scalability, enabling construction firms to adapt the technology to various project sizes and complexities.

The involvement of prominent investors like OpenOcean signals confidence in Sitegeist’s market potential. OpenOcean’s track record in backing deep-tech startups adds credibility to the funding round, while angel investors such as Verena Pausder provide strategic guidance and networking opportunities. With €4M in funding, the startup is well-positioned to expand operations and refine its platform.

However, challenges remain. Competing with established players like Brokk AB and Husqvarna AB will require aggressive scaling and differentiation. Additionally, regulatory hurdles in the construction sector could complicate deployment timelines. Nonetheless, Sitegeist’s innovative approach and strong investor backing make it a startup to watch.

Why This Matters for Industry Stakeholders

For construction firms, Sitegeist’s technology offers a solution to persistent labour shortages and rising costs. The ability to automate complex tasks in unstructured environments could significantly reduce project timelines and improve operational efficiency. This is particularly critical for large-scale renovation projects where delays can have cascading impacts.

Investors in the construction and robotics sectors should take note of Sitegeist’s modular technology and autonomous capabilities. The scalable design allows for adaptation across various use cases, from concrete removal to sandblasting and drilling. Stakeholders in public infrastructure could also benefit from faster project turnarounds, reducing the societal and economic costs of ageing assets.

Forward Outlook

Looking ahead, Sitegeist’s immediate priorities include scaling its team, expanding test environments, and deploying robots with construction partners. The startup has already outlined plans to explore additional use cases, such as sandblasting and drilling, which could broaden its market reach.

As demand for infrastructure renovation continues to climb, Sitegeist’s technology is poised to gain traction.
