Heaviside Industries Raises $28M in Series A Funding

May 12, 2026 | By Startuprise io

Heaviside Industries, a Los Angeles, CA-based defensetech startup, has raised $28 million in a Series A funding round led by Interlagos with participation from Menlo Ventures, Flume Ventures, Cantos, Anorak Ventures, Frank Finelli (Senior Advisor, Former Partner & Managing Director at The Carlyle Group), Paul Dimitruk (Co-Founder, Vice Chairman & Senior Partner at Partners Capital), and Aaditya Devarakonda (Former CEO of Dedrone).

The company plans to use the capital to speed up the development, production, and delivery of autonomous precision munitions across air, sea, and other domains for U.S. and allied special operations and conventional forces, including the first rollout of aerial and underwater systems.

Modern warfare is increasingly driven by unmanned systems, and highly precise weapons are becoming essential for future battlefields. Low cost autonomous strike capabilities help U.S. and allied forces target important enemy assets, and infrastructure more efficiently, while reducing collateral damage compared to traditional methods.

Heaviside develops precision munitions designed to operate in contested environments where older systems may not perform well, while keeping costs under control and maintaining strong performance.

"American defense is overdue for reinvigoration — and modernizing it requires large-scale manufacturing and precise, affordable capability at operational scale. Heaviside has put both under one roof for the first time: the engineers behind the most successful miniaturized military UAS ever fielded, a manufacturing program that has shipped tens of thousands of systems to the U.S. and our allies, and a guidance group with over 100,000 flight hours in contested environments. That depth is why we invested and why Heaviside will define this generation of American defense." - Matt Kraning, Partner at Menlo Ventures.

“Investment in American defense is critical to maintain our essential freedoms. We are proud to invest in Heaviside, whose technologies contribute to the strength of our strategic defense system.” – Scott McNealy, Operating Partner & Investor at Flume Ventures.

“This Series A fundraise allows us to accelerate the deployment of Heaviside’s autonomous munitions platforms to a broad base of our established customers. Our products are designed for hyper-precision in jammed and GPS-denied environments, fundamentally shifting the dynamics of modern warfare. With this capital, we will further the adoption of Heaviside’s technology by warfighters.” – Phillip Walker, CEO of Heaviside.
