CEOs of Epirus & Galvanick on the Future of Defense & Cybersecurity

Drones + Shocking Unclassified Information

Oct 06, 2025

NextGen Defense Unclassified.

U.S. Veterans Andy Lowery, CEO of Epirus, & Joshua Steinman, CEO of Galvanick, join Sourcery to break down the next frontier of defense, from drone swarms to industrial cyber threats.

The defense landscape is entering a new era defined by drone swarms, cyber-physical attacks, and the reindustrialization of America’s supply chains. Traditional “mass vs. mass” warfare is being replaced by asymmetric threats that demand both next-generation hardware & cutting-edge cybersecurity.

(PS After recording these interviews my videographer, nervously turned to me, & asked “were we allowed to hear that?” Yes. Insane, but unclassified information. Thank you Joshua!)

Epirus & Galvanick, two significant companies with incredibly impressive veteran leaders are directing this shift:

Andy Lowery, a retired Lieutenant Commander from the U.S. Navy and former Raytheon engineer who now leads Epirus, building directed energy systems to neutralize drones at scale
Joshua Steinman, a Navy veteran who served four years on the National Security Council in the Trump White House before founding Galvanick to defend industrial control systems that underpin America’s manufacturing and critical infrastructure.

Together, we explore:

What the sixth domain of warfare means for modern conflict.
How Epirus’ Gen 2 systems are extending range and production readiness.
Why cybersecurity for industrial infrastructure is mission-critical.
The role of defense tech in America’s reindustrialization.
Where geopolitics, AI, and national security intersect in the decade ahead.

This conversation is part of Sourcery’s “Made in America” Mini-Series recorded at the Reindustrialize 2025 Summit.

Epirus & The “Sixth Domain of Warfare”

Epirus is a defense technology company pioneering directed energy systems to counter the rise of drones and drone swarms in modern warfare.

Epirus has raised over $550M from 8VC, Washington Harbour Partners, StepStone, General Dynamics, T. Rowe Price, and Gaingels, building its Leonidas™ solid-state, high-power microwave weapon to counter drones and drone swarms. 8VC’s Joe Lonsdale has called Leonidas “the best protection against drone swarms today” and a technology that could become determinative for the future of warfare. The company is now fielding its second-generation Leonidas system, which offers 2.5x the range in the same compact form factor and is designed for deployment across bases, vehicles, ships, and even space-based platforms

Lowery explains how Epirus is pioneering the “sixth domain of warfare”—physical cyber attacks—and how their “one-to-many” defense approach gives the U.S. a strategic edge against mass drone threats.

Beyond the technology, Epirus is positioned at the heart of America’s reindustrialization push. Building these systems at scale requires revitalizing domestic supply chains for critical components like high-power microwave amplifiers, manufacturing capabilities that largely moved overseas decades ago. By re-establishing this capacity in the U.S., Epirus is not only defending against emerging threats but also helping rebuild the defense industrial base needed for sustained security and resilience.

Thank you for the Lego set!!!

Galvanick tackling the cyber front.

Galvanick is a cybersecurity company focused on protecting industrial control systems (ICS) and supervisory control and data acquisition (SCADA) — the backbone of America’s factories, energy grids, and defense supply chains. While IT cybersecurity has seen massive investment (with companies like CrowdStrike reaching $100B valuations), the operational technology (OT) side remains almost entirely unprotected.

Steinman founded Galvanick after four years on the Trump White House National Security Council, where he was responsible for cyber, telecom, and supply chain policy. He saw firsthand how adversaries were already pre-positioning on U.S. critical infrastructure.

Galvanick’s platform automates what would normally take teams of human analysts weeks or months: correlating industrial data streams in real time, detecting anomalies, and surfacing threats within minutes. With a team pulled from Amazon’s OT security group, Google, Uber, and Wall Street, Galvanick is positioned to become the frontline defender of America’s industrial base at a time when cyberattacks can disable steel mills, water plants, or even weapons manufacturing before a single shot is fired.
