One of the flagship events of EDTH Defense Tech Days, the London Defense Tech Hackathon, will bring together 150+ ambitious engineers, founders, investors, Ukrainian frontline practitioners, and members of the UK military to rapidly prototype technologies addressing real operational challenges.

Come to find a potential co-founder, test an idea against real operational needs, and meet the people building and buying the next generation of defense technology!

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.
