Bedrock Robotics Raises $600 Million at $4.1 Billion as Its Driverless Excavators Do Paid Work on Live Job Sites

Bedrock Robotics, a San Francisco startup that retrofits heavy construction machines with an autonomous driving system, has closed a $600 million Series C at a $4.1 billion post-money valuation. The company announced the round on Monday, eight months after raising $270 million at $1.75 billion, and total funding now stands at nearly $1 billion.

CapitalG and Emergence Capital co-led the round. New investors include the US Innovative Technology Fund, Bessemer Venture Partners and Temasek, while existing backers 8VC, Georgian, Valor Equity Partners, Xora, Eclipse, Perry Creek Capital and Nvidia participated. Bloomberg first reported the deal.

What separates Bedrock from a crowded field of construction autonomy startups is that its machines have moved past supervised testing. Since mid-August, excavators running its system with nobody in the cab and nobody operating them remotely have been doing paid work on live commercial projects: a water treatment facility in Nevada with Sundt Construction, a large earthmoving project in Texas with Champion Site Prep, and a 1.2-million-cubic-yard civil sitework job with Zachry Construction. The company hit its stated goal of fully autonomous customer deployments in 2026 roughly six months early, about two years after founding.

Bedrock was founded in 2024 by Boris Sofman, who previously led autonomous trucking at Waymo, along with other former Waymo engineers. The company says it now works with more than 15 partners across 23 states and has more than doubled its customer base since 2025, and it has signed its first commercial agreements for fully autonomous deployments. New customers announced with the round include Haydon, an employee-owned contractor from Tempe, Arizona running the system on a remote Texas site, plus 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. Two executives with driverless-vehicle backgrounds have joined: Amy Jones Satrom, formerly of Amazon, Nuro and Uber, as vice president of operations, and Lando Juarez, formerly Uber autonomous mobility counsel, as general counsel.

The pitch rests on a labor math problem. US data center construction hit a record annual pace of about $85 billion in August, up roughly 73 percent from a year earlier, and the industry needs about 349,000 net new workers in 2026 while contractor backlogs stretch past eight months, nearly ten for data center work. Roughly 40 percent of the current construction workforce is expected to retire by 2031. Excavators are both the first step of every project and one of the hardest seats to fill: they take five or more years to master and make up about a quarter of a typical contractor fleet.

Bedrock is not alone in chasing the opportunity. Gravis Robotics in Switzerland raised $200 million in August, Eka Robotics raised $150 million last week, and Formic raised $50 million. Bedrock says the new capital will put more machines on customer sites and pay for the field teams that keep them running.

The valuation jump from $1.75 billion to $4.1 billion in eight months is a bet that construction autonomy has crossed from demo to revenue. For now Bedrock has the strongest evidence in its category: real contracts, real sites, and excavators digging for customers with the cab empty.
