Monumental secures $32M Series B to accelerate construction automation

Monumental,
the Amsterdam-based construction technology company developing autonomous
robotics and software for the building industry, has raised $32 million in a
Series B funding round led by Khosla Ventures, with participation from existing
investors Plural and Hummingbird.

Founded
by Salar al Khafaji and Sebastiaan Visser, Monumental is addressing labour
shortages in construction through autonomous bricklaying robots powered by its
AI platform, Atrium. The company’s electric robots combine advanced sensors,
computer vision and cranes to lay bricks and mortar with millimetre precision.
The robots are deployed as autonomous subcontractors on construction sites.

Rather
than selling robots directly, Monumental provides a construction service in
which contractors pay for completed walls instead of purchasing and operating
equipment. The outcome-based model removes the financial and operational
complexity of adopting robotics while allowing builders to increase capacity
without expanding their workforce.

Monumental
currently operates a fleet of more than 150 robots across construction projects
in the Netherlands and the UK. Its robots have helped build more than 100
homes, as well as a school, community centre, hotel and canal walls. Nearly
half of those homes were completed during the past three months, reflecting a
rapid increase in deployment.

Salar al
Khafaji, co-founder and CEO of Monumental, said the global construction
industry lacks the workforce needed to meet rising demand and that increasing
capacity requires practical automation rather than experimental technology.

Every
robot we deploy expands the industry’s capacity to build, bringing a future of
beautiful, affordable, bespoke buildings and infrastructure closer to
reality,

he added.

Monumental
has recently strengthened its presence in the UK by appointing a dedicated
country manager and expanding its local team. Alongside further growth across
Europe, the company is preparing its first pilot projects in the US as it
continues its international expansion.

The
funding will support the company’s next phase of growth by expanding its team
of hardware and software engineers, increasing the deployment of its robotic
fleet across Europe and the UK, strengthening its UK operations, broadening the
range of construction tasks its robots can perform, and supporting its planned
expansion into the US.
