Monumental raises $32 million Series B to bring bricklaying robots to the U.S.

The Amsterdam company operates as a masonry subcontractor, with contractors paying for finished walls rather than buying and operating robotic equipment.

Monumental has raised $32 million in Series B funding and plans to launch its construction-robotics business in the U.S. this year, the company said.

The Amsterdam-based company designs, machines, and maintains robots that lay bricks at construction sites. Monumental said the funding will support a U.S. launch, additional robot deployments across Europe, growth in its hardware and software engineering team, and an expansion of the tasks its robots can handle beyond bricklaying.

Monumental operates as a subcontractor during construction work. Contractors pay the company for finished walls rather than owning and operating the robots themselves, a model the company said removes the financial and technical risk of operating the equipment.

The company said its electric, autonomous robots use sensors, computer vision, cranes, and its Atrium AI software platform to lay bricks and apply mortar with millimeter precision. The robots can also use specialized tools for tasks including inserting wall ties and pointing mortar.

Monumental said its robots work on active construction sites alongside human crews. The company has framed the technology as a way to take on repetitive bricklaying work while allowing skilled workers to focus on other tasks amid persistent construction labor shortages.
