Everything's a robot | Cofounder/CEO @PrismaXai

Westmag is building American robot actuators and drone motors at scale. In 2025, @westmagco raised $11M led by @a16z, with participation from @FoundersFund, @LuxCapital, NFDG, @MenloVentures, and other top investors. Since then, we’ve been building industrial capacity, crawling up supply chains, and securing high-volume customers. Now, we’re ramping production at our factory in South San Francisco to deliver against committed offtake orders from high-volume customers. Westmag is committed to scaling quickly in the US to deliver millions of drone motors and robot actuators to the surging domestic and global market. We’re building the great American motor and actuator company.

We're proud to lead Westmag's Seed Round. One of the underrated advantages of investing across the entire hardware stack is firsthand exposure to the supply chain challenges that plague our industrial base. When one starts mapping which single points of failure could take down entire product lines, motors and actuators rise to the top of the priority list. China currently dominates this landscape. The result is that many American drone, robotics, and defense companies are building on a foundation they don’t control. Since our first meeting over tacos and beers last summer, Westmag has moved at a blistering speed from inception to shipping motors from their first factory. Regulatory tailwind, combined with exploding demand from defense and humanoid robotics, means the timing for what Westmag is building has never been better, and the cost of not having it has never been more obvious.
