Value proposition

Solves the global skilled labor shortage and improves worker safety by automating high-risk, physically demanding tasks like sandblasting and concrete repair with high-precision AI robotics.

Products and solutions

["Modular Robotic Base Platform","AI-driven Autonomous Navigation System","Concrete Renovation Module","Automated Sandblasting & Surface Treatment Module","Sitegeist Control Software"]

Unique value

Unlike traditional fixed automation, Sitegeist uses a modular hardware approach combined with AI that can navigate and operate in the highly unstructured and unpredictable environments of active construction sites.

Target customer

Construction companies, civil engineering firms, and infrastructure maintenance contractors specializing in large-scale concrete and surface renovation.

Industries served

["Construction","Civil Engineering","Infrastructure Maintenance","Robotics & AI"]

Technology advantage

Leverages proprietary research from the TUM Robotics Institute to enable robots to perform complex 'dirty, dull, and dangerous' tasks with a level of adaptability and precision that reduces project timelines and operational costs.

How they differentiate

Sitegeist utilizes a modular hardware approach combined with AI that allows a single robotic base to perform multiple specialized tasks (e.g., sandblasting, concrete repair). Unlike single-purpose robots, its system is designed specifically for the unstructured and hazardous environments of infrastructure renovation.
