Why Seoul

Europe's Biggest Defense-Tech
Hackathon Comes to Korea

EDTH has run hackathons across Europe's defense-tech capitals, connecting builders directly with military operators, government stakeholders, and investors. For the final stop of its 2026 tour, it chose Seoul — partnering with D4D, the APAC defense-tech builders network that ran Asia-Pacific's first civilian-led defense hackathon in July 2026.

Teams build against real defense and security problem statements with direct feedback from military operators and domain experts. Standout teams can advance toward post-event demonstration stages through EDTH's government and investor network — the emphasis is deployment, not prototype-only outcomes.
