SOBRE ESTE EPISÓDIO
Matija had 24 hours to get a satellite propulsion system across the world. FedEx couldn't guarantee it. UPS couldn't either. So he got on a plane and delivered it himself. 23 hours, round trip.
Jacob, his co-founder, hit the same wall from a different direction. He was a marine during Typhoon Haiyan, tasked with getting life-saving supplies of medicine and food to people fast. Aircraft kept breaking down, parts weren't in stock, pilots were exhausted. The supplies got there late.
Different problems, same wall: nothing fast enough existed. Not for a startup, not for the US military. So they built it.
Hop Aero builds autonomous hypersonic cargo rockets. 250 kg, up to 750 km, in about 15 minutes. Most urgent logistics still runs through airports, runways, slow last-mile handoffs, or cargo sitting in orbit waiting for a window. Hop Aero's bet is simpler: launch from a 40-foot shipping container, fly point-to-point through a suborbital arc, land vertically on ground that was never built for landing.
In this episode, Nihal Kurth sits down with Matija Milenovic, co-founder and CEO of Hop Aero. They get into why time-critical logistics breaks down in both military and commercial settings, how a prototype catching fire turned into the real test of a co-founder relationship, and why Hop Aero optimizes for door-to-door speed instead of just flight speed.
They also cover why drones fail at long-range contested logistics, how Ukraine changed the cost and availability of autonomy hardware, why Hop Aero built its own internal engineering system, Hop OS, and what it actually takes to build a defense hardware company in the US instead of Europe.
