Defense Unicorns Raises $136 Million Series B to Build the Software Backbone of the Department of War

Defense Unicorns, the leader in airgap software delivery for national security mission systems, announced the completion of a $136 million Series B financing round led by Bain Capital. The investment brings the company to unicorn status with a valuation exceeding $1 billion, driven by the company’s rapid and profitable growth. The company has seen a 300% increase in adoption year-over-year in military systems.

The Department of War is prioritizing modernization and speed, and Defense Unicorns’ platform addresses a critical infrastructure challenge by enabling secure, rapid software updates across disconnected environments from submarines, ships, and aircraft to forward operating bases. Warfighters often operate in conditions where connectivity is limited or nonexistent, and the ability to deploy software updates securely and instantly is now essential to mission success. Unicorn Delivery Service (UDS) bridges high security requirements while supporting partners and allies with modern software solutions essential for next-generation national security capabilities.

“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 “The U.S. has significant commercial software advantages, but the systems we go to war with are typically outdated.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,” continued Dr. Slaughter.

The funding round was led by Bain Capital’s Tech Opportunities fund, the growth technology platform of Bain Capital. With participation from Ansa Capital, Sapphire Ventures, Valor Equity Partners, AVP, Uncorrelated Ventures, and the former Director of the Central Intelligence Agency, David H. Petraeus.

“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.

Demand for secure software delivery continues to rise. 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 defense, and this next chapter only reinforces the scale of impact ahead.”

“Before UDS, there was no open, secure, and airgap-native modern software delivery capability for warfighters. More than just a piece of software, UDS is an entire open ecosystem of tools and technologies purpose-built to securely bring capabilities to the field faster. I’m grateful for the incredible teams at Defense Unicorns that continue to evolve UDS to bring even more technical advantage to our nation’s heroes,” concluded Co-Founder and CTO Jeff McCoy.
