Defence technology has long struggled with a simple contradiction that the most critical systems often operate where the internet does not. The gap is now becoming one of the most valuable frontiers in modern defence software. Defense Unicorns is building software specifically for these disconnected environments, enabling secure updates and rapid deployment even when systems are completely cut off from the internet.
Now, Defense Unicorns has reached unicorn status after closing a $136 million Series B round, pushing its valuation beyond $1 billion. The funding round was led by Bain Capital through its Tech Opportunities platform, with backing from a mix of growth investors and national security leaders, including former CIA Director David H. Petraeus.
The capital will be used to scale products designed to modernise defence software without compromising security. At the core is Unicorn Delivery Service (UDS), a portable, airgap-native runtime that simplifies packaging, deployment, monitoring, and sustainment of mission applications.
Making software speed a battlefield advantage
Across submarines, aircraft, ships, and forward operating bases, warfighters frequently operate without reliable connectivity. Yet mission software still needs to be updated, secured, and maintained at speed.
Founded in 2021 by veterans Rob Slaughter, Jeff McCoy, and Andrew Greene, Defense Unicorns was built around a clear idea that software itself can act as a strategic deterrent. By combining open-source principles with airgap-native design, the company enables secure development and sustainment across cloud, on-premises, and tactical-edge systems.
Defense Unicorns’ platform focuses on exactly that challenge: delivering software safely across air-gapped systems where failure or delay can cost lives.
Turning open-source innovation into frontline capability
Alongside it sits UDS Registry, an American-maintained software registry built for extreme environments. It addresses a growing concern in defence circles: securing the software supply chain end-to-end, even when systems are cut off from the outside world.
A newer initiative, UDS Army, aims to close another long-standing gap. Commercial software vendors often face slow, complex paths into defence deployments. UDS Army combines secure DevSecOps pipelines with pre-authorised cloud environments, giving vendors a faster route to deliver mission-ready tools directly to soldiers.
Trusted by operators across the U.S. Navy, Army, Air Force, and Space Force, Defense Unicorns is turning one of defence’s hardest constraints, which is disconnection into a strategic advantage.
“Defense Unicorns gives our nation a wartime software advantage,” said Dr. Rob Slaughter, CEO of Defense Unicorns. “The U.S. has significant commercial software advantages, but the systems we go to war with are typically outdated. At Defense Unicorns, we make software a strategic deterrent by making it easy to deploy and operate software in any mission environment,” he continued.
“We are thrilled to support Defense Unicorns as it works to ensure that U.S. service members have access to the most advanced, secure, and rapidly deployable software possible. Defense Unicorns plays a vital role in helping the military modernize mission systems, enabling capabilities that directly improve readiness, resilience, and operational advantage in the field,” said Dewey Awad, a Partner at Bain Capital Tech Opportunities.
Marco DeMeireles, Co-Founder and Managing Partner at Ansa Capital, stated, “We’ve been proud to partner with Defense Unicorns since the Series A, and our continued investment reflects the conviction we’ve built watching the team execute against an incredibly complex and mission-critical problem. What Rob and the team have built is foundational infrastructure for modern defence, and this next chapter only reinforces the scale of impact ahead.”
