About this event
If you care about building technology that matters in the real world, this is where you want to be. The European Defense Tech Hackathon - London brings together people who want to work on hard, meaningful problems at the intersection of defense, dual-use technology, and ambitious engineering. This is an in-person gathering for builders, operators, researchers, and curious newcomers who are ready to collaborate under time pressure and turn ideas into working prototypes. Expect a room full of people who care less about buzzwords and more about whether something can actually be built, tested, and used. About the Event At its core, this hackathon is a focused working session built around defense and dual-use tech. That means projects may explore tools, systems, or workflows with applications in national security, resilience, logistics, communications, sensing, autonomy, cyber, or adjacent areas where technical capability has real operational value. The format is straightforward: people come together in person, form teams, identify a problem worth tackling, and spend concentrated time building. Some attendees will arrive with a clear project idea. Others will show up looking for a team, a challenge, or collaborators who bring complementary skills. Because this is a hackathon, the emphasis is on momentum. You should expect a practical environment where conversation quickly turns into scoping, prototyping, testing assumptions, and showing progress. It is a strong fit for people who like fast feedback loops and want to pressure-test ideas in a room full of capable peers. This event also sits within a broader community context. Beyond the build itself, it is a chance to meet others interested in European defense capability, dual-use innovation, and the kinds of technologies that become more important when reliability, speed, and real-world constraints matter. What to Expect You can expect the day to revolve around a classic hackathon arc: arrival, team formation, problem selection, building time, and project sharing. The exact flow may vary, but the spirit is clear: get aligned quickly and spend the bulk of your time making tangible progress. Typical activities at an event like this include: Meeting other attendees and finding teammates with the right mix of technical and domain skills Pitching ideas or joining a project that already has a strong direction Defining a concrete problem instead of trying to solve everything at once Building prototypes that demonstrate a workflow, capability, or decision-support tool Sharing outcomes with the room at the end in a concise, practical format The strongest teams usually focus on a narrow problem with a clear user, constraint, or mission context. Rather than abstract future concepts, expect a bias toward useful outputs: a demo, a model, a dashboard, a simulation, a toolchain improvement, a hardware-adjacent concept, or a technical proof of feasibility. There is also real value in the conversations around the building. You will likely spend time comparing assumptions, discussing operational use cases, and learning how others think about resilience, procurement realities, field constraints, and the gap between a technically elegant idea and one that can actually be adopted. Why Attend If you have been looking for a community of people who take defense and dual-use technology seriously, this event is a strong entry point. It gives you a reason to move from passive interest to active participation, surrounded by others who are equally motivated to build. You should attend if you want to sharpen your thinking by working on problems with higher stakes and tighter constraints than a typical consumer-tech project. Defense-adjacent work often demands clarity, tradeoff awareness, and a deep respect for reliability, usability, and deployment context. A hackathon is one of the fastest ways to experience that mindset in practice. You may leave with: New collaborators for future projects, companies, or research A prototype or proof of concept you can continue developing A better understanding of defense and dual-use problem spaces Exposure to different skill sets, from software and systems thinking to operations and strategy A clearer sense of where you fit in this ecosystem, whether as a builder, operator, researcher, or founder Even if you do not arrive with a polished idea, the event can still be highly valuable. The right conversation, the right team, or the right problem statement can change the direction of what you build next. Practical Details This is an in-person event in London, United Kingdom, which means the value is not just in the hacking itself but in being physically present with other attendees. The in-room energy matters: quick introductions, rapid team formation, whiteboard discussions, and hands-on collaboration are all easier face to face. The event begins on Friday, February 20 at 12:00 PM GMT. If you plan to attend, it is worth arriving ready to engage early, especially if you want time to meet people, hear project ideas, and decide whether to start something new or join an existing team. A few useful ways to prepare: Come with one or two problem ideas you can explain clearly in a minute or less Bring the tools you need to build, prototype, or present effectively Be ready to describe your skills, background, and interests so others can quickly understand where you fit Stay open to teammates from different disciplines; the best projects often come from mixed perspectives Whether you are deeply embedded in the defense tech world or just starting to explore it, this hackathon offers a practical way to get involved. If you want to spend a day in London building with serious people on serious problems, this is exactly that.
Who should attend
This is for people who want to do more than talk about defense and dual-use technology. - You are a **software engineer, hardware builder, product thinker, data scientist, researcher, or technical founder** who wants to apply your skills to higher-stakes problems. - You are interested in **defense, resilience, security, logistics, autonomy, communications, cyber, or mission-critical systems** and want to explore those areas through hands-on work. - You like **hackathon environments** where the goal is to move fast, make decisions, and leave with something concrete rather than just exchanging ideas. - You already have a **project concept or problem statement** and want teammates, feedback, and momentum to push it forward. - You do not need to be an existing defense insider. If you are **curious, technically capable, and serious about learning the space**, you will likely find the right conversations here. - You value being around a **community of builders and operators** who care about practical outcomes, real constraints, and technology that can hold up outside a demo. If you want to meet sharp people, work on meaningful problems, and see where you fit in the European defense tech ecosystem, you should feel at home here.
