This startup’s autonomous excavators helped it secure $600 million in new funding.

Bedrock Robotics has raised $600 million in a funding round, bringing the autonomous vehicle technology startup’s valuation to $4.1 billion—a testament to the rapid ascent of the two-year-old company.

The Series C round was co-led by CapitalG and Emergence Capital. It comes just two months after the startup reached a major milestone: transitioning its autonomous excavators from testing and pilot programs to active use on real-world construction sites.

Bedrock Robotics has developed an autonomous kit that can be retrofitted onto construction and other job-site vehicles. Currently, excavators equipped with Bedrock’s autonomous technology are in commercial operation at a water treatment plant in Nevada, an earthworks site managed by Champion Site Prep in Texas, and a 1.2-million-cubic-yard civil engineering project led by Zachry Construction Corporation.

Since its founding in 2024 by a group of veterans from the autonomous vehicle and robotics industries, Bedrock has raised nearly $1 billion. Co-founder and CEO Boris Sofman previously led the now-defunct autonomous trucking program at Waymo. Sofman also co-founded and led Anki Robotics—the company behind the popular consumer robot Cozmo—which shut down in 2019.

Other co-founders include Waymo alumni Kevin Peterson, who serves as Bedrock’s Chief Technology Officer, and Ajay Gummalla, who serves as Vice President of Engineering and Infrastructure. Tom Eliaz, formerly of Segment and Twilio, is also a co-founder and serves as Vice President of Engineering and Hardware.

This new capital will help Bedrock accelerate its transition toward commercial-scale projects. The company plans to deploy its technology across more construction sites while expanding its team and infrastructure to better support clients in the field.

“We have proven that fully autonomous excavators can work alongside existing personnel and workflows on construction sites to deliver real value,” Sofman said in a statement. “The next challenge is to scale this capability to more contractors, making it a reliable component of construction projects.”

Bedrock is focusing specifically on autonomous excavators, partly due to a growing shortage of skilled operators. According to the company, it takes at least five years—if not longer—to master the operation of an excavator. Meanwhile, a large number of construction workers are nearing retirement. Associated Builders and Contractors, a national trade association for the construction industry, estimates that more than 40% of the construction workforce will retire over the next five years.

Bedrock believes that the construction industry will increasingly turn to autonomous technology to help bridge this labor gap.

The startup’s latest partner is Haydon, an Arizona-based general contractor that plans to deploy Bedrock-equipped machinery across a range of projects, including advanced manufacturing facilities, water and wastewater treatment plants, data centers, and healthcare facilities.

New investors—US Innovative Technology Fund (USIT), Bessemer Venture Partners, and Temasek—participated in this funding round, alongside existing investors including 8VC, Georgian, Valor Equity Partners, Xora, Eclipse, Perry Creek Capital, and NVIDIA.

As it scales its commercial operations, the startup also announced two executive appointments. Amy Jones Satrom, a veteran with experience at Amazon, Nuro, and Uber, has joined Bedrock as Vice President of Operations. Lando Juarez, who previously served as Head of Legal for Autonomous Mobility and Delivery at Uber, has been hired as the company’s General Counsel.
