Monumental Secures $32 Million to Transform Construction with Robots
Amsterdam-based startup Monumental has recently raised $32 million in Series B funding, led by Khosla Ventures. This funding will be used to expand its innovative fleet of autonomous bricklaying robots across Europe, the UK, and, for the first time, the United States.
The construction industry in the UK is facing a significant challenge, needing around 20,000 more bricklayers to meet its housing targets. Yet, only about 1,990 individuals completed their apprenticeships in 2024. Monumental’s technology, featuring a fleet of 150 robots, is stepping in to help tackle this shortage on construction sites.
Founded by Salar al Khafaji and Sebastiaan Visser, who previously created Silk—acquired by Palantir in 2016—Monumental uses Palantir’s unique forward-deployed engineering model in the robotics space. This model places technical teams directly with customers, going beyond just selling software.
“Right now, the construction industry lacks enough skilled workers to meet demand, and the solution isn’t simply more apps or theatrical robots. We need machines that can lay real bricks on-site all day, which is what our fleet does,” said Salar al Khafaji, co-founder and CEO of Monumental.
Since World War II, productivity in construction has only increased by about 10%, while manufacturing productivity has surged by eight times. The UK is currently facing a shortage of about 6.5 million homes, one of the highest deficits in Europe. The market for construction robots is projected to grow from $1.4 billion in 2024 to approximately $3.66 billion by 2030, with an annual growth rate of 18%.
Monumental’s Unique Approach
Started in 2021, Monumental operates under a distinct business model. Instead of selling or leasing robots, the company acts as a subcontractor, charging contractors for completed brick walls rather than the robots themselves. This allows builders to hire Monumental like any other contractor, without needing to invest in or maintain machinery.
In the broader landscape, Monumental finds itself among a growing group of companies in the construction robotics sector. Companies like Australia’s FBR, which produces the Hadrian X bricklaying robot, also use a similar “wall as a service” model. However, Monumental differentiates itself by assuming all the labour risk, which aligns with the viewpoint that labor shortages pose a major challenge in construction.
Impressive Numbers
Monumental claims that its fleet of over 150 robots has completed walls for more than 100 homes across the Netherlands and the UK, with nearly half of these being finished in just the last three months. The company is also involved in various projects, including a school, hotel, community center, and infrastructure around canals.
Vinod Khosla, founder of Khosla Ventures, highlighted the pressures on construction costs, noting that Monumental’s projects serve as evidence that robotics can help reduce these costs on a larger scale. Sten Tamkivi from Plural remarked on Monumental’s position as one of the leading autonomous construction operators in the world, addressing a significant global issue from its base in Europe.
As Monumental continues its work on job sites and explores further funding opportunities, the ultimate impact of robotics on the housing crisis remains to be seen.
