Monumental Raises $32M to Bring Construction Robots to the U.S.

Monumental, an Amsterdam-based company specializing in construction robotics and software, has secured $32 million in Series B funding. The company announced it will use the capital to enter the U.S. market later this year and broaden the range of tasks its robots can perform on job sites.

“The funding will help to grow our world-class team of hardware and software engineers, launch the company in the U.S. this year, scale the number of robots it can deploy across Europe, and expand the range of construction tasks the robots can handle beyond bricklaying,” said Salar al Khafaji, co-founder and CEO of Monumental, in a statement to The Robot Report.

How the robots build walls

Monumental’s electric, autonomous robots combine advanced sensors, computer vision, and cranes to lay bricks and mortar with millimeter precision. The entire operation is managed by Atrium, the company’s proprietary AI software platform.

“Our robots autonomously build masonry structures by laying bricks and applying mortar on active construction sites alongside a human crew,” al Khafaji explained. “They are also able to pick up special tools for additional tasks, such as inserting wall ties and pointing the mortar. They handle the repetitive, physically demanding bricklaying process with millimeter precision, working directly from digital building plans through our software, Atrium.”

Monumental operates as a subcontractor, charging contractors for finished walls rather than for the robots themselves. The company notes this model removes the financial and technical risks of owning and operating equipment.

“Our goal isn’t to replace people, but to give the industry the additional capacity it desperately needs,” al Khafaji said. “By taking on repetitive bricklaying work, the robots allow skilled workers to focus on higher-value tasks while helping the industry build more homes and infrastructure despite persistent labor shortages.”

Human operators remain essential on site. “Humans remain responsible for the broader construction process,” al Khafaji noted. “The existing crew continues to manage the overall project, prepare the site, coordinate with other trades, and perform all work outside of the masonry process. Monumental’s own operators deploy and oversee the robots, replenish materials, perform maintenance, and intervene if an unexpected situation arises that requires human judgment.”

Addressing the U.S. labor shortage

The U.S. construction market faces a chronic labor deficit, with between 200,000 and 400,000 workers missing each month. Home builders will need to add 2.2 million more workers over the next three years just to keep pace with demand. Monumental aims to help close that gap.

Al Khafaji acknowledged that the U.S. market is more fragmented than Europe, with building codes, labor structures, and practices varying by state. “Monumental is uniquely positioned for this kind of challenge,” he said. “We’ve already proven our ability to adapt our robots across different customers and construction practices in Europe, and our software-driven approach makes it possible to tailor deployments to local building methods and regulatory requirements. Just like any subcontractor, we work closely with contractors to integrate into their existing workflows.”

The company’s robots have already built the walls of more than 100 homes across the Netherlands and the U.K., along with a school, a community center, a hotel, and canal walls.

Real-world success drives investor confidence

Khosla Ventures led the Series B round, with additional participation from Hummingbird, Plural, and others. Al Khafaji said the company’s proven track record was key to winning investor support.

“The biggest lesson that we learned is that this actually works. Our Series A round was focused on R&D and proving small-scale success,” he said. “Our Series B was raised off of real-world success. Real construction sites are the best R&D lab.”

He added that “there are many unwritten unknown unknowns in construction which we’ve discovered by being deployed in the real world. Building 100 homes has taught us how to make the system more reliable, easier to deploy, and better integrated into the day-to-day realities of construction.”
