Monumental, an Amsterdam-based construction robotics company founded by former Palantir engineers, has raised $32 million in a Series B round led by Khosla Ventures. Existing investors Plural and Hummingbird also participated.
The company was founded in 2021 by Salar al Khafaji and Sebastiaan Visser, who previously co-founded Silk, a data analytics startup acquired by Palantir in 2016. Monumental applies Palantir’s forward-deployed engineering model to construction, deploying robots that physically build infrastructure including hospitals and schools.
Monumental currently operates a fleet of 150 bricklaying robots across Europe and plans to enter the US market with 100 additional units. The US construction sector faces a shortage of 200,000 to 400,000 workers per month, a gap the company aims to fill.
Construction costs have risen dramatically while productivity in the sector has declined since the 1960s. Monumental’s robots automate the most labor-intensive parts of masonry work, potentially reducing build times and costs.
Europe’s robotics sector has seen surging investor interest. In June, German humanoid robotics company Neura raised $1.4 billion at a $7 billion valuation.
Monumental previously raised $25 million in 2024. The company plans to use the new funds to expand its engineering team and the range of construction tasks its robots can perform.
