Leigh Madden
Vice President, National Security Group, US Federal, Microsoft
Leigh Madden is shaping how AI and cloud capabilities are delivered to DOW and intelligence community — integrating Microsoft’s National Security Group into a unified force aligned around operational outcomes and moving from fragmented pilots into mission-scale deployment.
The proof is in the field, Madden said. Customers have compressed targeting workflows, with a former national security leader noting publicly that targeting cells have collapsed intelligence operation timelines from hours to minutes for sensing to engagement. That is what happens when technology stops being a pilot and starts reshaping the operating model, fundamentally shifting how technology translates into real-world advantage on the battlefield and beyond.
“Industry is carrying the R&D load,” Madden said. “Microsoft and the other builders in the defense innovation base are funding the models, compute and data pipelines at frontier scale — and embedding that AI directly into mission workflows so our customers can operate at the speed of the threat.”
But as AI becomes inseparable from the mission, leaders have to think about capacity differently, he said, treating it like munitions: plan it, fund it and stockpile it before you need it.
“The hyperscalers can’t do that alone — it takes a real partnership with government to put capacity in the budget and have it staged, ready to deploy,” Madden said. “Do that, and you turn data into action in minutes instead of months. That’s how we bend the curve on innovation.”
Why Watch
In 2026, Madden and his team are forcing the inflection point, taking AI from experimentation to decisive, mission-critical capability.
“Our adversaries and the mission won’t wait for the next budget cycle, and neither should the capabilities we put in the hands of the warfighter,” Madden said.
Silicon and foundation models are evolving so rapidly that the latest frontier model running on the most powerful silicon today will soon be overtaken by a new model and new silicon at a pace faster than anything previously seen, Madden said. The team at Microsoft is focused on delivering the intelligence layer that will enable multi-model AI, applying the right model, on the right silicon, at the right time to enable decision superiority and mission outcomes.
“Leigh Madden is a trusted leader who consistently delivers impact at the intersection of mission and innovation,” said Carmen Krueger, corporate vice president of U.S. federal at Microsoft. “Through his leadership, we are helping our national security customers operate as true Frontier Agencies, leveraging advanced cloud and AI capabilities to move faster, make better decisions and strengthen readiness. Leigh’s ability to translate complex challenges into outcomes at scale is making a meaningful difference for those who serve and protect.”
Fun fact: Fifteen years in the Navy taught Madden he can endure cold water — though he chooses not to anymore. “Skiing, on the other hand, has taught me that cold is perfectly enjoyable when you’re going downhill on skis,” he said.
