European Defense Tech Hackathon – Paris
Time to Accelerate European Defense Innovation
Join us and 120+ hackers from all across Europe and beyond for the European Defense Tech Hackathon on November 7–9, 2025, in Paris, France.
After our first Paris hackathon with 170 attendees last November, we're excited to be back! This is your chance to connect with fellow defense innovators, meet potential co-founders, and work on projects that have the potential to save lives.
We'll prepare challenges based on real-world problems, and you can bring your own project. You'll get feedback from experienced mentors, and we'll put you in a position to deploy your project in the real world after the hackathon 🚀

Note: We updated the date and place from early September in Marseille to the beginning of November in Paris.
Goals
1) Solve urgent defense and security challenges: Each hackathon features a fresh set of challenges sourced directly from frontline partners in Ukraine, NATO, and across the EU—driven by real needs, not theory.
2) Launch new careers and companies: Whether you're breaking into the defense sector or building your own product and company, we connect you with jobs, funding, and pathways toward real-world deployment.
3) Strengthen Europe through defense innovation: Here is where Europe's top talent meets the most pressing threats. By building and shipping, we demonstrate what a fast, capable, and resilient European defense ecosystem looks like.
