About Heaviside Industries

Heaviside Industries is a defense technology company that develops and manufactures multi-domain autonomous precision munitions for the United States and its allied forces. Founded in 2024 by CEO Phillip Walker, the company emerged from stealth mode in May 2026 after operating quietly for over two years. Walker has extensive experience selling custom systems to U.S. government customers, providing him with a deep understanding of the defense procurement process. The company is headquartered in Los Angeles, California, with an additional office in Oslo, Norway.

The firm's core business revolves around producing cost-effective, highly precise munitions designed to operate in contested, GPS-denied environments where traditional systems might fail. Heaviside aims to achieve sub-one-meter accuracy at an affordable price point, addressing a critical gap in modern warfare. The business model appears to be a combination of direct hardware sales and government contracts (B2G), targeting clients such as U.S. and NATO special forces and conventional military units. The technology is already being tested by these end-users.

Heaviside's product portfolio spans air, land, and sea domains. Specific products in development include the TYR autonomous aerial munition and the HYDRA autonomous underwater munition. The company's strategy involves working closely with operators to build solutions that meet specific mission requirements. To secure its supply chain and enhance its product capabilities, Heaviside formed a strategic partnership with Nammo, a Norway-based aerospace and defense company that will serve as the warhead supplier for Heaviside's platforms.

Since its founding, Heaviside has secured significant funding to scale its operations. After emerging from stealth with a $28 million Series A round in May 2026, the company raised an additional $60 million in a Series B financing just three months later, reaching a valuation of $600 million. Key investors include Felicis, Hedosophia, Menlo Ventures, Cantos, and Interlagos Capital. The capital is being used to increase production capacity, accelerate hiring, and fulfill existing customer commitments.
