Bedrock Robotics Raises $600M to Automate Excavators

San Francisco startup Bedrock Robotics announced a $600 million Series C on October 26, valuing the company at $4.1 billion. Investors include Valor Equity, 8VC and Nvidia's venture arm.

Founded in 2024, Bedrock does not build machines. It sells a kit of sensors and computing that turns existing heavy equipment into autonomous vehicles. According to the company, the hardware can be installed in a day, is not a permanent modification and fits excavators from 20 to 80 tons from several manufacturers. It has already been deployed on Caterpillar 352 and 336 models, at a water treatment plant in Nevada and on earthmoving jobs in Texas.

How the system works

The system, called Operator, uses lidar, GPS and motion sensors to perceive its surroundings. An onboard computer plans movements and carries out complex tasks once a site manager sets the day's plan. It includes safety features similar to those in self-driving cars, such as stopping immediately and without assistance if an unauthorized person or object gets too close. No one sits in the cab, but a human supervisor oversees operations and can step in.

The company has moved fast. It emerged from stealth in July 2025 with $80 million in early funding, then closed a $270 million Series B in February at a $1.75 billion valuation. The latest round followed the news that its excavators were working fully autonomously on customer sites. Bedrock says its customer base has doubled since 2025, with contracts across numerous US states.

Labor shortage as the pitch

Bedrock argues that training an expert machine operator takes five years. The industry's trade association estimates the sector needs 349,000 net new workers in 2026 and 456,000 in 2027, while retirements loom and immigration policy puts at risk a third of a workforce born abroad. Bedrock says one in five construction workers is over 55.

The funds will go toward bringing the technology to more machines and strengthening field work, commercial and operations teams. The company has hired an operations vice president with Amazon and Uber experience and a legal executive from Uber's autonomous driving unit. It also plans to test larger equipment, such as giant bulldozers and articulated trucks. Rivals are emerging abroad too: Switzerland's Gravis Robotics received $200 million from SoftBank this summer.
