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 February 20-22, 2026, in London, UK. Goal We want to bridge the gaps between technologists, the public sector, investors, and operators in dual-use and defense technology. This hackathon will demonstrate the talent and drive of the European ecosystem. Get inspired by the challenges we have prepared, or feel free to bring your own project. You'll get feedback from folks who have been on the frontline to ensure you're solving real problems. Our goal with the hackathon is to put you in a position to continue towards deployment. Visitors To give participants time and space to focus on their projects, we'll have no visitors during the hackathon. If you're curious about the outcomes and what the teams have built, please sign up as a visitor for our Demo day on Sunday.
