Monumental raises $32M to scale its bricklaying robots into the US
What's the deal? Monumental, a Dutch construction robotics startup, has raised an oversubscribed $32 million Series B led by Khosla Ventures. Plural and Hummingbird Ventures also participated. The company builds robots that lay bricks on active construction sites.
What's the endgame? Monumental sells outcomes, not machines. Contractors don't buy or rent its robots or software; instead the company bids for jobs and gets paid only when it delivers finished walls.
Why now? Chief executive officer Salar al KhafajiDealroom has a profile for this one. Try Dealroom → says the technology has cleared a key bar. "Our team has achieved one of the rarest things in this industry: getting beyond demoware," he wrote, noting the robots are deployed with paying customers.
To date, Monumental's robots have delivered brickwork for 100 homes, a school, a community centre, a sports centre, a hotel, commercial units, and hundreds of metres of Amsterdam's canal walls. Half of that output went up in the three months to July 2026, according to al Khafaji.
Where's it expanding? The round funds two priorities at once. Monumental will scale its fleet across Europe and enter the US later in 2026, while investing in R&D toward more autonomy, new skills, and new materials.
The signal: Construction is among the largest and least automated industries in the world, and labour for traditional masonry is increasingly scarce. Monumental's pay-per-wall model — and its work on custom colour patterns, curved walls, and masonry specials — points to how robotics firms are moving from prototypes to permanent, revenue-generating fixtures on real job sites.
