Ep. 96: Robert Slaughter, Defense Unicorns
Rob Slaughter’s company exists because of a year and a half of pain. Early in his Air Force career he was handed a gnarly problem. It lived right at the intersection of his physics and computer vision background. Despite knowing how to solve it from a tech perspective, the data and systems he would have needed to stitch together all lived at different classification levels. He spent eighteen months trying to work the policy approvals to connect the tools he needed, but was ultimately unsuccessful. In a tale as old as time, Rob then received orders, and he moved on to the next assignment. But the problem followed him. “Every assignment, every month, every year, same issues. I know I can solve this problem. I just can’t get the software I need,” Rob said. And that’s where the Defense Unicorns story begins. About Dr. Rob Slaughter Rob joined the Air Force to pay for his physics degree. After missing out on the ROTC scholarship in his first year, he got it his second. While he initially planned to serve out the commitment and leave, he instead fell in love with the people and the mission. But the service, it turns out, does not need many physicists. What it does need is people who understand software. Modern physics is computation heavy, so while as a physicist “you are a terrible software engineer,” Rob says you do “know more than probably the person next to you.” So he kept getting assigned to the most software intensive job in the room. Rob looked at what DIU, AFWERX, and Kessel Run were doing. He liked Kessel Run the most but did not like how locked it was to a single vendor. So he recruited the best engineers he could find, including future co-founders Jeff McCoy and Andrew Greene, and started SpaceCAMP. It was meant to be an open source, Kessel Run style effort for space. Rob believes it ran some of the first Kubernetes deployments in classified environments. About a year later, Nic Chaillan and Dr. Will Roper pulled the team up to build what became Platform One. About Defense Unicorns Rob left in March 2021 to start Defense Unicorns. He came to realize that on the inside, you cannot truly control hiring and firing. From his perspective, “You cannot pay people what they are worth.” You cannot keep them. And he was spending much of his time drowning in finance and contracts. “Because it’s so hard to do the simple things, you never actually have time for the hard things.” There was also a design limit. Platform One existed to stitch together other people’s open source. It was about tuning someone else’s platform. Rob’s big idea for Defense Unicorns was to rebuild from the ground up, with the Pentagon as the only customer that mattered, from the start. The standard dual-use advice was to find commercial traction, get to a Series B or C, then get FedRAMP and back into government. By then, he argues, the architecture is set, and it was “always gonna be a terrible experience” for the defense customer. The core product Defense Unicorns offers is called UDS, or the Unified Defense Stack. It packages software once and deploys it to cloud, ships, aircraft, and edge systems, including networks with no internet connection. It is built in layers, so what goes on a fighter jet is different from what goes on a submarine or into a cloud. The company’s stated mission is “to make software a strategic deterrent,” which Rob defines as the ability to update software on 100 percent of systems every twelve hours. Defense Unicorns raised a $136 million Series B in January 2026 at a valuation above $1 billion, and its Navy work recently moved from a lab test in San Diego to testing at sea. And yes, there is a unicorn named Doug. Rob’s argument for Doug goes like this: the company’s largest customer, a submariner named Bill, has spent four decades on submarines in and out of uniform. “You do not have to remind Bill how serious his job is.” A logo with a sharp edge does not make his work feel more serious. People are at their best when they can laugh once in a while. (Rob also points out that the military has always done this, from cartoon nose art on WWII bombers to unit patches.) A little levity goes a long way.
