Monumental raises oversubscribed $32M Series B led by Khosla Ventures
Monumental raised an oversubscribed $32 million Series B led by Khosla Ventures, with Plural and Hummingbird Ventures participating, to scale its autonomous bricklaying fleet across Europe and expand into the United States.

Evidence notes
- 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.
Company context
Monumental designs, builds and operates fleets of autonomous bricklaying robots on live construction sites in the Netherlands, United Kingdom and United States. Founded in Amsterdam in 2021, it reports more than 100 robots, 40 projects and 100 homes completed.
