European Defense Tech Hackathon - London
Time to Accelerate European Defense Innovation 🚀
Join us and 100+ hackers from all across Europe and beyond for the European Defense Tech Hackathon on June 26-28, 2026, in London, UK.
Connect with fellow defense innovators, meet potential co-founders, and build projects with real-world impact that could save lives.
We’ll bring challenges rooted in pressing defense and security problems, and you’re welcome to bring your own ideas.
Throughout the event, you’ll get hands-on guidance from seasoned mentors—and after the hackathon, we’ll help you take your project closer to real-world deployment 🚀

Goal
1) Solve urgent defense and security challenges: Each hackathon features a fresh set of challenges sourced directly from frontline partners in Ukraine, the UK, 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.
