Bedrock Robotics announces $600 million round for autonomous excavators

Bedrock Robotics, a San Francisco startup founded in 2024, announced a $600 million Series C round with participation from investors including Valor Equity, 8VC and Nvidia’s venture arm. The company says its excavators are already operating fully autonomously at customer worksites; Xataka reports that the round raised Bedrock’s valuation to $4.1 billion.

Bedrock does not manufacture the machines. Instead, it retrofits existing 20- to 80-ton excavators with the Operator system, which combines lidar, GPS, motion sensors and computing to plan and execute tasks. Installation can be completed in one day and is reversible. The system can stop by itself when it detects an unauthorized person or object, while a human manager supervises operations and can intervene. The technology has already been used on Caterpillar 352 and 336 models, at a water-treatment plant in Nevada and in earthmoving projects in Texas, according to Xataka.
