Demetrius on Europe's Defense Inflection & Delian's Sensor Network
After sponsor reads and an audio check, Demetrius — the show's second Demetrius of the day and founder/CEO of defense company Delian — argues European defense is at an inflection point, with drone incursions showing even wealthy nations can't guarantee safe airspace and a decade-long infrastructure project ahead. Explaining a tweet about Jericho, he describes Delian as a solutions provider aiming to become a prime, fusing hundreds of cameras and radars into a single software brain for the Greek army and Greek civil protection. The stack includes border surveillance towers, edge computers that make manned posts unmanned, the portable Jericho unit, the StrikeWeb software platform, and a software-defined jammer shown to neutralize drone swarms in NATO exercises.
From Apple Robotics to Athens: Founding Delian & Going Global
Demetrius recounts growing up in Athens, studying electrical engineering, then moving to the US on a fellowship to research GPS-denied navigation before joining Apple in 2016 amid a wave of roboticists leaving academia. Nostalgia for Europe, plus anxiety over the Armenia–Azerbaijan war showing drones defeating a legacy army and early signs of Anduril, pushed him to move his family back to Athens in 2021 and start Delian. He says the current defense boom lets Delian expand internationally, with recent capital funding demonstrations across European, Asian and Middle Eastern markets, backed by an international team with Apple, Facebook and Stanford backgrounds.
Building a Defense Prime: Contracting, Hiring & Skunkworks Lessons
Demetrius calls defense product development a 'dark art' of roughly seven parallel processes — technological, political and operational — built on relationships with end users and elite military units rather than simple tenders. He says defense startups are the opposite of 2010s software advice, requiring manufacturing, financing, compliance, government relations and even RF electronics, and that aligning people who'd never otherwise meet (policy, special forces, machinists) is the secret sauce of building a prime. On management he cites SpaceX and 1960s–70s defense R&D labs, recommending the Lockheed Skunkworks memoirs, before the hosts close out episode seven with sponsor reads.
