Foundry Robotics' $100M Series A — Owning the Factory, Not Just the Robot

Foundry Robotics raised an oversubscribed $100 million Series A to expand its Emeryville factory and deploy its physical AI robot cells and FoundryOS platform.

What happened

On October 28, 2026, Foundry Robotics, an Emeryville, California-based company that builds and operates autonomous factories for complex assembly, announced an oversubscribed $100 million Series A funding round led by Marlinspike Partners. Participating investors include early backers Khosla Ventures and Red Glass Ventures, new investors SE Ventures, Wing VC, and Axiom Ventures, and existing investors Hanabi and Zero Shot Fund.

Foundry says the funding will build out its Emeryville facility, accelerate the deployment of AI models into real-world manufacturing, and grow its robotics research, engineering, and factory operations teams. The company has expanded its manufacturing footprint twentyfold to a 130,000-square-foot facility in Emeryville.

Why the model matters

Foundry's argument starts from a bottleneck claim: defense and industrial companies can design new hardware faster than ever, but manufacturing remains the constraint. Traditional assembly lines, the company says, are built around a single product, take months to deploy, and are costly to reconfigure. Its answer is flexible assembly capacity that deploys quickly, adapts to different products, and scales with demand.

The business model is the distinction. Rather than selling a robot for a customer to integrate into its own plant, Foundry owns and operates the factory itself, offering manufacturing-as-a-service: it takes customers from design to production in weeks, the company says, without new production-line investments or expensive retooling on the customer's side. What it must deliver, then, is finished hardware at manufacturing-grade precision and traceability — not a machine that can merely demonstrate an assembly task.

The technical stack has three layers. Foundry trains AI models on the building blocks of assembly and deploys them in a grid of robotic "cells" with manufacturing-grade precision. FoundryOS serves as a single agentic system linking the robots, the factory floor, and the cloud. Every production run feeds back into the models, so — in the company's formulation — the same cell that assembles a drone today can learn to build a satellite component tomorrow, and gets better at both with every run.

What the platform already shows

Foundry serves defense and commercial industries, focusing on high-value, complex electro-mechanical products where production is constrained. The applications it names span drones, autonomous vehicle subassemblies, wire harnesses, underwater vehicles, telecom and data center infrastructure, ground robots, rugged computers, robot compute boxes, and satellites.

The founding team is drawn from the worlds the factory serves. Co-founder and CEO Adarsh Kulkarni was employee number 4 at Ghost Robotics, where he built legged robots for the U.S. military, and later became Scale AI's inaugural Head of Robotics. Co-founder Emmanuel Lamacchia was the single-threaded owner for Tesla's Model Y program, responsible for manufacturing about 1.5 million cars a year, according to the announcement. The leadership team also includes former Tesla software leader Anup Karmakar and veterans of Raytheon and Northrop Grumman.

Outside voices in the announcement frame the bet as a capacity question, not a robotics demonstration. Duane Fotheringham, President of HII Unmanned Systems, says: "Production capacity is a national constraint on getting unmanned systems to the fleet." Marlinspike Managing Partner Mislav Tolusic says defense and industrial equipment manufacturers "urgently need more domestic assembly capacity" and cites the speed of execution — assembling the team, commissioning the first factory, and signing customers.

What this does not show

A $100 million funding announcement is not a production result. The announcement discloses no valuation, no revenue figure, no margin or backlog figure, and no customer names, customer counts, or production volumes tied to this capital. Claims that customers are being signed "quickly" carry no disclosed numbers, and the company's description of its factory as America's first autonomous factory for assembly is its own framing, not an independently verified ranking. The "design to production in weeks" figure describes the model's intent, not a disclosed average across shipped programs. Foundry was founded in 2026, so this Series A is a bet on a very young company's ability to turn flexible assembly cells into repeatable output at scale — the proof will be finished hardware delivered on schedule, not the size of the round.
