Foundry Robotics Raises $100M Series A to Build an Autonomous Assembly Factory

Foundry Robotics has raised $100 million in an oversubscribed Series A round led by Marlinspike Partners. The Emeryville, California, company announced the funding on October 28, 2026.

Foundry builds and runs its own factories for complex assembly work. AI-controlled robot cells and human manufacturing experts work side by side to put together products such as drones, satellites and ground robots.

The company did not disclose its valuation, its total funding to date or its revenue.

Foundry Robotics Series A funding and investors

Marlinspike Partners led the $100 million Series A. Early backers Khosla Ventures and Red Glass Ventures returned, along with existing investors Hanabi and Zero Shot Fund.

SE Ventures, Wing VC and Axiom Ventures joined as new investors, FinSMEs reported. Foundry described the round as oversubscribed.

Mislav Tolusic, managing partner at Marlinspike, said defense and industrial equipment makers urgently need more assembly capacity in the US. He said Foundry’s factory offers that capacity in a form that can scale and change with demand.

How Foundry Robotics’ autonomous factory works

Traditional assembly lines are built for one product. Foundry’s factory uses a grid of AI-controlled robot cells that can be set up for different assembly jobs.

The company trains AI models on common assembly steps and deploys them across those cells. Its FoundryOS software connects the robots, the factory floor and cloud systems.

Data from each production run feeds back into the models. Foundry says this helps the system improve with every run.

Experienced manufacturing staff work alongside the robots. Foundry says the mix lets it handle assembly tasks that have been hard to automate.

What Foundry Robotics builds and for whom

Foundry serves defense and commercial customers. It focuses on high-value electro-mechanical products where production capacity is limited.

Products it assembles include drones, autonomous vehicle parts, wire harnesses, underwater vehicles, satellites, ground robots, rugged computers and data center equipment, according to Robotics and Automation News.

Customers do not buy robots or build their own lines. Foundry owns and runs the factory, and says clients can go from design to production in weeks without paying for new production lines or retooling.

Foundry has not named any customers or shared production results.

What Foundry Robotics will do with the $100 million

The money will go toward building out the Emeryville facility and putting more AI models into real-world production. Foundry will also hire across robotics research, engineering and factory operations.

The company has already grown its manufacturing space twentyfold, to 130,000 square feet. That implies a starting footprint of about 6,500 square feet.

Founder and CEO Adarsh Kulkarni said the factories needed to rebuild US manufacturing must be “rethought from the ground up.” He said adding automation to one part of an existing plant is not enough.

Robotics funding in 2026

Foundry’s round lands during a strong year for robotics investment. Global venture funding for robotics startups reached $9.9 billion in the third quarter of 2026, up from $4.3 billion a year earlier, according to Crunchbase data cited by Hoodline.

Robotics funding for the first three quarters of 2026 is up about 185% from the same period in 2025, by the same count. Larger rounds this year include Skild AI’s $1.4 billion raise and Xpeng Robotics’ $900 million round.

Foundry Robotics competitors

Several other companies sell factory capacity as a service. US defense manufacturer Hadrian, Re:Build, Amca and Divergent have each raised far larger sums than Foundry.

Foundry’s focus is final assembly in a factory designed around robots from the start, rather than machining parts or adding automation to an older plant.
