Bedrock Robotics raises $600 million after its retrofitted excavators began paid, operator-free earthwork in August

Bedrock Robotics announced on October 26, 2026, that it has raised a $600 million Series C at a $4.1 billion post-money valuation, co-led by CapitalG and Emergence Capital. The San Francisco company sells a retrofit kit that lets an existing excavator dig with nobody in the cab. Bedrock says those machines have done paid work on live commercial sites since mid-August, and the new money goes toward putting more of them on earthwork and sitework jobs.

What it does

The product is called the Bedrock Operator. According to Bedrock’s August announcement, a crew installs a sensor and compute package on an excavator the contractor already owns, in one day and with no permanent changes to the machine. A site manager sets the initial plan. From there, a single machine learning model perceives the surroundings, plans its motion, and carries out the digging. Bedrock says the model was trained across tens of thousands of field hours.

On safety, Bedrock says its excavators work next to other equipment in normal site conditions without barriers. If a person or an unauthorized object comes too close, the machine stops until the area is clear.

So on a contractor’s job, the superintendent and the grade foreman would work with it most, since they set the dig plan and run the trucks and support equipment around it. The equipment manager decides which machines get the kit. Bedrock picked excavators first because, it says, they often make up 25% of a contractor’s fleet and take five years or more to learn to run well. Dump trucks, dozers and loaders are on its list for later.

Evidence so far

The evidence is Bedrock’s two press releases, comments from customers and investors in them, and a reading of the news by the construction technology newsletter Bricks & Bytes. Here is what Bedrock reports:

1. Operator-free excavators began paid work on commercial sites in mid-August 2026, after a year of testing under human supervision.
2. It has more than doubled its total customer volume since 2025. The release gives this as a ratio, without a customer count.
3. In August, it counted 15 general contractor partners operating across 23 states.

The named jobs and new contracts are below.

Read the yardage carefully. Bricks & Bytes points out that 1.2 million cubic yards is the size of Zachry’s sitework project. The volume the autonomous machine dug on that job is a separate figure. The newsletter’s editors list the questions that come next: uptime, cost per cubic yard, hours between human interventions, and whether customers order more machines. Production rates, intervention rates and pricing for the Bedrock Operator are not yet public.

Katie Haydon is CEO and chair of Haydon, an employee-owned general contractor in Tempe, Arizona. Katie Haydon said in the October release: “For us, the biggest win is a safer, more predictable job site.” Haydon is deploying the system on a remote Texas site and plans to test trench work and larger machines later.

US Innovative Technology Fund, Bessemer Venture Partners and Temasek joined the round as new investors, alongside existing backers such as NVIDIA and 8VC. Total funding is now close to $1 billion (in August, Bedrock put the figure at $350 million). Bedrock also hired Amy Jones Satrom, formerly of Amazon, Nuro and Uber, as VP of operations, and Lando Juarez, who led legal for Uber’s autonomous mobility and delivery business, as general counsel. Bedrock says the hires support its growing footprint on customer sites.

How to measure it on your projects

Track cost per bank cubic yard (earth measured in place, before it swells) for each excavator on a mass excavation scope. Add the machine’s hourly owning and operating cost to the operator’s burdened hourly wage, multiply by hours worked, and divide by bank cubic yards moved. Our post on computing an equipment hourly rate with the Corps of Engineers method covers the first term.

If you get a pilot, capture the baseline first on a crewed machine in similar material:

1. Engine hours and idle hours per shift from telematics.
2. Bank cubic yards per shift, taken from survey or grade-check quantities rather than truck counts.
3. Operator hours and the burdened wage rate.
4. Trucks loaded per hour, since a slow loading cycle holds up the haul fleet too.

During the pilot, log the same four items for the autonomous machine. Add every automatic stop and every time someone took control, with the minutes lost. Count the hours of the person setting dig plans and watching the machine in its cost column. Leaving that time out makes the robot look cheaper than it is. The labor productivity method from daily logs and timecards works for the crew side of the comparison.

A first step on one job: have the grade foreman record bank cubic yards and engine hours for one excavator every shift for two weeks.

Availability and cost

Bedrock describes its model as co-developing autonomy with general contractors on their own machines. The new contracts in the October release take the machines beyond the West and Central South into the Midwest and South Atlantic. Pricing is not public, and the release lists press@bedrockrobotics.com as its contact. For another robot that works next to a crew, see our post on Origin’s OG-1 drywall finishing robot.
