Westmag Aims to Reshore America’s Robotic Muscle with $11M Seed Round

SOUTH SAN FRANCISCO, CA – June 02, 2026 – In a significant move to rebuild America’s industrial base for robotics, Westmag has emerged from stealth with an $11 million seed round led by Andreessen Horowitz (a16z). The company, whose name is short for Western Magnetics Company, is tackling a decades-old dependency on foreign manufacturing for the critical components that give drones and robots motion: electric motors and actuators.

With participation from Founders Fund, Lux Capital, and other top-tier investors, Westmag is not just developing new technology; it is building a high-volume manufacturing capability on U.S. soil. The company is already ramping up production at its South San Francisco headquarters to fulfill committed orders for hundreds of thousands of units, signaling a powerful market pull for a secure, domestic supply chain.

Addressing a Critical Supply Chain Choke Point

For decades, the global supply of high-performance drone motors and robot actuators has been overwhelmingly concentrated in China. This dependency has evolved from a simple economic calculation into a pressing national security and economic resilience issue. As the American drone and robotics industries expand, their reliance on foreign components creates significant supply chain risks and throttles the pace of domestic innovation.

The market for these components is vast and growing rapidly. The global drone motor market alone was valued at nearly $2.4 billion in 2024 and is projected to exceed $5.7 billion by 2029. The robot actuator market is on a similar trajectory, expected to double to nearly $4 billion by 2030. Without a domestic industrial capacity, U.S. firms are left vulnerable to geopolitical friction, shipping delays, and intellectual property risks.

“Most of the hardware, especially the motors and actuators that actually bring motion to physical AI, has been built outside of the U.S. But it doesn’t have to be this way,” said David Hansen, Co-Founder and CEO of Westmag. “Westmag is aggregating the rising demand to quickly scale production capacity and become the trusted supplier of high performance, cost effective motors and actuators.”

This strategic imperative is underscored by a strengthening regulatory environment. Washington has grown increasingly wary of foreign-made drone technology, leading to policies like the American Security Drone Act and provisions in the National Defense Authorization Act (NDAA) that restrict federal procurement of foreign systems. The Federal Communications Commission’s anticipated ban on new models of foreign-made drone components, cited by Westmag as effective December 2025, represents a powerful tailwind for the company's mission to onshore this critical industry.

Powering the Future of 'Physical AI'

Westmag’s investors see the company as more than just a component manufacturer; they see it as a foundational enabler for the next generation of American technology. The motors and actuators Westmag produces are the essential “muscles” of what the tech industry calls “physical AI”—the drones, humanoids, and autonomous systems that interact with the real world.

“Motors and actuators are the muscle of physical AI, and right now America’s share of that muscle is essentially zero,” said Erin Price-Wright, general partner at Andreessen Horowitz. “Without a domestic industry, every American drone company, every robotics company and every defense prime is building on a foundation they do not control.”

This lack of control has been a quiet brake on innovation. U.S. robotics companies have had to design their systems around the availability and specifications of foreign parts, often facing long lead times for custom designs and limited transparency into the components themselves. By providing a reliable, high-performance, and cost-effective domestic alternative, Westmag aims to unlock a new phase of growth and experimentation.

“Western drone and robot companies should benefit from the compounding advantages of reliable, cost effective domestic component supply,” said Jordan Sanders, Westmag's Co-Founder and COO. “That’s why we’re building Westmag to be the great American motor company serving the global market.” This vision aligns perfectly with a16z's broader thesis of investing in deep tech companies that build “atoms, not just bits,” creating the foundational hardware that will underpin future software-driven advancements.

A Blueprint for American Deep Tech Manufacturing

Challenging the long-held belief that high-volume manufacturing is no longer viable in the United States, Westmag is implementing a modern production strategy designed for scale and efficiency. The company is vertically integrating its design, manufacturing, and supply chain at its launch facility, dubbed Factory 01.

At the core of this strategy is a shared architecture. By recognizing that drone motors and robot actuators are composed of many common materials and production processes, Westmag can design and build both on a unified platform. This approach, powered by flexible automation and replicable production modules, allows the company to serve a wide variety of customers and applications with high SKU mix and high volumes.

Inside Factory 01, Westmag designs, automatically winds electromagnetic stators, assembles, and validates every unit on its integrated production lines. This level of control is critical for ensuring quality and security. To fortify its supply chain, the company is partnering with key suppliers in the U.S. and allied countries like Japan, while also investing upstream in subcomponent production, such as steel stamping and rare earth magnet finishing. This gives Westmag greater control over its bill of materials and cost structure.

According to Price-Wright, this manufacturing prowess is the key to victory. “The win condition is not a marginally better motor. It is the ability to make a lot of them, here, on a platform that serves both drones and robots,” she stated.

Westmag’s initial go-to-market strategy has focused on securing supply offtake agreements with select high-volume customers, allowing it to de-risk its initial capacity ramp. With this foundation, the company plans to roll out a wider range of standardized products that smaller-volume customers can easily design into their systems. By establishing itself in the Bay Area, Westmag has placed itself at the epicenter of the talent, capital, and customers required to scale its ambitious vision and help power the resurgence of America's advanced industrial base.
