European Defense Tech Hackathon — Paris

Around 150 hackers from across Europe spend a weekend in Paris building defence technology prototypes, co-organised with the team behind the Adopt AI Summit. Three challenges are set: stopping Shahed-class and fibre-optic drones, tracking targets across messy sensor setups, and keeping systems working under jamming. Participants can take those on or bring their own project, with feedback from people who have frontline experience. Team formation Friday from 12:00, building Saturday, Demo Day Sunday. Visitors are not admitted during the hacking phase; Demo Day opens at 13:00 on Sunday to EDTH Community Visitor ticket holders. Attendance is by application. Run by the European Defense Tech Hub. The venue is not published on the event page.
