Defence Hackathon 2026 x Aalto Defence

Real problems. Real stakes. Solutions that could shape tomorrow's defence landscape.

A 48-hour Hackathon for students working at the intersection of technology and national security.

With a grand prize of 20 000€ provided by 17Tech. Winner team will get a guaranteed spot in their defence tech accelerator which includes a 20 000€ seed funding and mentorship.

We live in an era where technology determines not just how conflicts are fought, but whether they happen at all. Credible defence capability is what allows diplomacy to function, institutions to persist, and societies to build.

That's why this hackathon exists: because the people who shape defence technology shape the conditions under which everything else becomes possible.

Defence technology has become a central priority in Europe because the continent’s security environment has changed rapidly in recent years.

New domains of conflict, cyber, space, AI, and autonomous systems, are reshaping how defence is conducted, creating urgent demand for innovation beyond traditional military contractors.

With the growing uncertainty that surrounds us it is important to stay innovative – register now!
