Bedrock Robotics has raised a $600 million Series C at a $4.1 billion post-money valuation to expand its fully autonomous construction equipment across US job sites, just two years after the startup was founded in 2024.
This brings Bedrock’s total funding to nearly $1 billion. The round more than doubles the valuation Bedrock secured in February, with its $270 million Series B at $1.75 billion, when it became a unicorn.
The round was co-led by CapitalG and Emergence Capital. New investors include US Innovative Technology Fund, Bessemer Venture Partners and Temasek, alongside existing backers 8VC, Georgian, Valor Equity Partners, Xora, Eclipse, Perry Creek Capital and NVIDIA.
The raise follows a milestone in mid-August, when the San Francisco company’s autonomous excavators began performing paid work on live commercial sites.
“We have proven that fully autonomous excavators can perform real work of value alongside the crews and workflows already in place,” said CEO Boris Sofman. “The next challenge is delivering that capability to more contractors as a dependable part of how projects get built.”
Bedrock was founded by former Waymo engineers and retrofits existing machines, starting with excavators. It says it has more than doubled its customer volume since 2025.
The latest customer is Haydon, an Arizona-based general contractor which is deploying Bedrock’s system for autonomous earthwork at a remote site in Texas. Haydon plans to expand across building and heavy civil projects, and to test trench work and larger machine models.
Bedrock has also signed contractors in several new regions, including Wagner Construction in Minnesota, Smith Trucking Company in Florida, B&S Site Development in Virginia, Native Excavating in Colorado, Clarkson Construction in Missouri and C.W. Matthews in Georgia. The deals take Bedrock beyond the West and Central South into the Midwest and South Atlantic.
The company is pitching autonomy as a response to the construction labour shortage. It cites figures showing 87% of construction firms have openings for hourly craft roles. Among firms with craft openings, 88% report that those positions are as hard or harder to fill than a year ago.
“Bedrock has moved with extraordinary speed from technical development to autonomous work on live commercial sites, just one year after emerging from stealth,” added CapitalG General Partner Derek Zanutto.
The company said its longer-term aim is mixed fleets that can orchestrate themselves across an entire job site.
