Resilience Conference Warsaw takes place on April 15 for a gathering of the defence tech ecosystem in Poland. The event will bring together military and government leaders, major defence companies, investors, and founders from across Central and Eastern Europe. Ticket sales close on Friday. You can register here, and be sure to explore the rest of the agenda.
We’re pleased to announce that Karl Rosander of Nordic Air Defence and Maciej Klimczak of Tantalit will take the stage at Resilience Conference Warsaw, bringing a timely conversation on cross-border defence collaboration and the evolving relationship between startups and primes in Europe.
The discussion will explore Tantalit’s partnership with Nordic Air Defence – marking the latter’s first collaboration with a Polish prime. The partnership is one example of the deepening ties between Nordic and Central European defence ecosystems that are being driven by shared urgency around the Russian threat. The panel will also discuss Tantalit’s strategic focus on the Polish market due to active defense spending and counter-drone initiatives.
This session will unpack the strategic decisions facing defence startups today – such as whether to partner, scale independently, or integrate with larger primes – alongside lessons from Tantalit’s trajectory and the realities of operating across borders.
