San Francisco-based Bedrock Robotics has raised $600 million in Series C funding at a $4.1 billion post-money valuation, as it expands autonomous construction machinery across commercial job sites in the United States.
The financing was co-led by CapitalG and Emergence Capital.
New investors include Bessemer Venture Partners, Temasek and US Innovative Technology Fund, alongside existing backers including Nvidia, 8VC, Eclipse, Georgian and Valor Equity Partners.
The round brings Bedrock's total funding to nearly $1 billion.
More importantly, it follows the company's transition from technology development into commercial work.
In August 2026, Bedrock announced that excavators equipped with its autonomy system had begun performing fully autonomous work on live, paying customer projects.
How Bedrock's Autonomous Excavators Work
Bedrock is developing software and hardware that can be installed on existing heavy construction equipment.
Its initial focus is excavators, machines used for digging, moving earth and preparing construction sites.
Conventional excavation requires a trained operator to manage the machine's movements while responding to changing terrain, materials and site conditions.
Bedrock aims to automate portions of that work using perception systems, planning software and machine controls.
Its technology is designed to understand the machine's surroundings, execute excavation tasks and adapt to changes encountered during operation.
That requires solving problems different from those faced by autonomous vehicles.
Construction sites change continuously. Excavation itself modifies the terrain, and machinery must operate around workers, trucks, changing materials and temporary obstacles.
Autonomous systems therefore need to interpret both the physical environment and the intended construction task.
Bedrock's initial commercial model involves retrofitting equipment contractors already own or lease rather than requiring an entirely new category of machinery.
The longer-term objective is to coordinate multiple types of equipment across a site.
Founded by Former Waymo Engineers
Bedrock was founded in 2024 by Boris Sofman, Kevin Peterson, Tom Eliaz and Ajay Gummalla.
The founding team previously worked on autonomous driving technology at Waymo.
Sofman, the company's CEO, also founded robotics startup Anki before joining the autonomous vehicle industry.
The founders are applying experience in safety-critical robotics to construction, an industry with different operational requirements but similarly complex real-world environments.
Their approach emphasizes deployment alongside existing contractors and work crews.
Paid Deployments and New Customers
Bedrock says its customer base has more than doubled since 2025.
The company announced additional construction partners including Haydon, Wagner Construction, Smith Trucking Company, B&S Site Development, Native Excavating, Clarkson Construction and C.W. Matthews.
Haydon is deploying Bedrock-equipped machinery at a remote construction site in Texas and plans to explore additional applications across infrastructure, manufacturing and data center projects.
Bedrock is also expanding geographically, moving beyond its initial operational regions into additional states.
These relationships demonstrate that contractors are willing to test the technology in real projects.
However, the company has not disclosed annual recurring revenue, the number of active autonomous machines or fleet-wide cost savings.
It has also not published sufficient comparative operating data to establish that autonomous excavation consistently outperforms conventional human-operated equipment.
Why Construction Automation Is Attracting Investment
Construction businesses face persistent labor shortages and demand for new infrastructure.
Expanding data centers, manufacturing facilities, utilities, transportation networks and housing requires substantial earthmoving capacity.
Yet adding workers and machines does not automatically produce proportional productivity improvements.
Projects can be delayed by equipment availability, scheduling constraints and shortages of experienced operators.
Autonomous equipment could allow contractors to operate machinery more consistently and complete certain tasks with less direct operator involvement.
This may be especially valuable for repetitive earthmoving operations in controlled areas of large construction sites.
Competition and the Economics of Deployment
Bedrock competes with established equipment manufacturers developing automation, including Caterpillar and Komatsu, as well as specialized robotics companies such as Built Robotics.
Its differentiation is the emphasis on retrofitting existing equipment and developing autonomy across different machines.
However, commercial viability depends on much more than successful excavation demonstrations.
Contractors need to understand hardware installation costs, uptime, maintenance, site preparation, insurance and productivity per operating hour.
Safety requirements are also fundamental because construction machinery can cause serious harm if perception or control systems fail.
Bedrock must prove its technology works across different materials, equipment models, job sites and weather conditions.
The Next Commercial Milestone
The company plans to use its new capital to increase deployments and expand field operations.
Its broader vision is a coordinated autonomous fleet capable of carrying out construction work with less manual intervention.
That objective remains substantially more complex than operating one excavator autonomously.
Bedrock's strongest achievement so far is moving autonomy into paid construction work. Its next test is proving that those deployments can scale safely, reliably and profitably across the industry.
