Bedrock Robotics has raised $600 million in Series C funding at a $4.1 billion post-money valuation, giving the San Francisco startup fresh capital to expand autonomous heavy equipment across U.S. construction sites. The round, announced October 26, was co-led by CapitalG and Emergence Capital and brings Bedrock’s total funding to nearly $1 billion.
The financing comes as Bedrock moves from testing its technology to putting autonomous excavators to work on paying customers’ projects. The company says its fully autonomous excavators began performing paid work at live commercial construction sites in mid-August. Its customer volume has more than doubled since 2025, although it has not disclosed the number of customers or machines deployed.
Bedrock takes a different approach from companies building entirely new robotic machines. Founded in 2024 by engineers with autonomous-driving experience at Waymo, it develops systems that can be retrofitted onto construction equipment contractors already own. Excavators are its first focus, with additional machine types and tasks planned as the technology matures.
Among its newest customers is Haydon, an Arizona-based general contractor deploying Bedrock-equipped machines for autonomous earthwork at a remote site in Texas. Haydon plans to explore wider use across building and civil construction projects, including trenching and larger equipment. Bedrock also named contractors in Minnesota, Florida, Virginia, Colorado, Missouri, Georgia and Arkansas as part of its expanding U.S. footprint.
New investors in the round include US Innovative Technology Fund, Bessemer Venture Partners and Temasek. Existing backers including NVIDIA, 8VC, Georgian and Valor Equity Partners also participated. The proceeds will support more commercial deployments and the field operations needed to maintain autonomous machines on active job sites.
