About Monumental
Monumental's compact electric machines divide masonry into coordinated transport, mortar-handling and brick-placement workflows. Machine vision and localisation align each course with the digital building plan, while Atrium connects robot control, construction sequencing and the site interface across the fleet.
The company delivers bricklaying as an operating service with its robots, software and field teams. It now works on live sites in the Netherlands, United Kingdom and United States. Monumental reports a fleet of more than 100 robots, more than 40 delivered projects and more than 100 homes built, extending its operating record beyond the Dutch housebuilding work previously represented on the profile.

- 2026-07-15 - Funding - Monumental raises oversubscribed $32M Series B led by Khosla Ventures
Khosla Ventures led the Series B, with existing investors Plural and Hummingbird Ventures participating. The Amsterdam company operates roughly 150 bricklaying robots and sells completed masonry work as a construction service rather than selling the machines. The capital is intended to expand the deployed fleet across Europe, enter the United States and increase the range of on-site construction tasks the platform can perform.

Plural and Hummingbird co-led the $25 million round, with Northzone, Foundamental, NP-Hard Ventures and Material Ventures also participating. Monumental said the funding would grow its team, increase deployed robot count and expand the block types and construction tasks its robots can handle. The company described small electric autonomous ground vehicles using sensors, computer vision and cranes to place bricks and mortar on construction sites.
