Join our EDTH Community here: https://community.eurodefense.tech/ ​​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. Who joins the hackathon? Hackers Hackers are the people actually building. They form small teams, pick a problem, and spend the weekend turning ideas into working prototypes. It starts on Friday with team formation, gets intense on Saturday, and ends on Sunday with our Demo Day where they show what they’ve built. Mentors Mentors are the ones helping the hackers with all the relevant expertise to build a defense tech project. They share real-world context and help teams avoid dead ends, whether it’s sharpening the problem, pressure-testing assumptions, or making something actually deployable. Visitors To give participants time and space to focus on their projects, there will be no visitors during the hacking phase (until Sunday, 12 pm). If you’re curious about the outcomes and what the teams have built, you can join the Demo Day on Sunday (from 1 pm) as an EDTH Community visitor by selecting a Community Visitor ticket.
