A hackathon held over the weekend in Amsterdam gathered more than 100 young programmers and engineers, aiming to create fast, affordable battlefield technologies to support Ukraine in its war against Russia. As Europe ramps up military spending in response to U.S. President Donald Trump’s warnings about pulling back NATO commitments, young tech talent is increasingly looking toward defence careers.
Participants of the hackathon, organised by the European Defense Tech Hub (EDTH) and Ukraine’s Brave1 defence accelerator, explored innovations ranging from drones and anti-drone tech to squad radar systems and seismic wave detection for enemy movement. While some attendees arrived with startup ambitions, others were there to network or show solidarity with Ukraine.
Among them was Emil Knutsson, a 24-year-old Swede, who noted a broader generational shift. “Even before the Russian invasion, I was interested in defence. But now, many of my peers are thinking the same way,” he said.
Interest in the event was further fuelled by recent geopolitical developments. According to Benjamin Wolba of EDTH, events like the Munich Security Conference and Trump’s more conciliatory tone toward Russia have created a renewed sense of urgency across Europe to invest in its own security infrastructure.
The hackathon also highlighted how defence innovation is no longer limited to governments or legacy contractors. Attendee Andreas Michaelides, whose team developed a seismic sensor system, said, “Every single one of us can get into this now,” pointing to the democratization of military tech development, especially in software and drone warfare.
Investor interest is also growing. Judge Bram Oostvogel of NUNC Capital, which recently announced a €20 million fund for early-stage defence startups, sees Ukraine as a real-world testing ground for ideas that could plug security gaps across Europe.
“First, you take care of security and safety – not Facebook likes,” Oostvogel said, emphasizing the shift in focus among both investors and innovators as the continent faces rising geopolitical threats.
With more hackathons planned across Europe this year, EDTH sees this as just the beginning of a new wave of grassroots defence innovation.
