Alphabet's CapitalG leads $270m round in US construction tech firm

Bedrock Robotics, a US-based autonomous construction technology company, has raised US$270 million in series B funding.

This brings its total funding to over US$350 million.

The round was led by CapitalG, Alphabet’s independent growth fund, and the Valor Atreides AI Fund, with participation from several other investors.

Founded in 2024, the company emerged from stealth in July 2025 and recently completed a large-scale supervised autonomy deployment on a 130-acre site.

Bedrock is developing connected autonomous fleets to improve productivity and safety in construction.

It is working with contractors on port infrastructure and earthmoving projects across multiple states.

The company plans to deploy its first fully operator-less excavators in 2026.

The new funding will support growth and leadership hires, including experts from Meta and Waymo.

🧠 Food for thought

Implications, context, and why it matters.

Bedrock’s strategy targets existing machines

Bedrock sells a retrofit kit for current excavators. It installs in one day and can be removed later 1.
A new excavator runs $500,000 to $1.5 million, bedrock CEO Boris Sofman said 2.
Updating equipment already in the field cuts upfront spending. That helps construction firms add automation 2.
The work is driven by former Waymo (Alphabet’s self-driving vehicle company) engineering leaders. The team includes the former head of Waymo’s trucking program and applies self-driving lessons to construction 3.

Autonomous fleets could reshape how construction work gets done

Automation aims to ease a labor shortage. Construction has more than 500,000 open jobs and 40% of workers are expected to retire within the next decade 4.
Autonomous machines could run 24/7. Bedrock says this can support round-the-clock schedules and boost productivity on large projects 4.
Funding interest is rising. The global autonomous construction machinery market is projected to reach $47.1 billion by 2033 5.
Retrofit providers may also need to manage friction with manufacturers. An investor post said companies such as John Deere (a farm and construction equipment maker) may resist or discourage third-party modifications 6.
