Defence Innovation Day 2026

Defence Innovation Day brings together leaders from defence, technology and investment to explore how innovation is continuing to push security across NATO and beyond. Now taking place for the second time, the event builds upon its focus from military defence to a broader concept of national resilience, including internal security, crisis preparedness and the role of dual-use technologies in responding to complex and hybrid threats. 

As the biggest science and business park in the Baltics and the home of the NATO DIANA Estonian accelerator (together with Sparkup Tartu Science Park), Tehnopol is passionate about supporting knowledge transfer, the transformation of technologies into viable business models, and their adoption by end-users. The Defence Innovation Day programme will address the realities of operating in sensitive and high-impact sectors: attracting investment into defence and dual-use innovation, validating and developing products, managing risks, and reaching operational users in both defence and civilian domains. 

Taking place in-person only on 21 September 2026 in Tallinn Creative Hub, the event will feature innovative pitches from future dual-use and defence unicorns, keynotes from industry leaders, and panels bringing together end-users and investors. Discussions will touch on internal security and crisis-readiness challenges, practical pathways from product development to deployment, and the expectations placed on companies building solutions for complex security environments. The programme is intended to speak directly to startups and growth companies while remaining grounded in the operational needs of the public sector and defence stakeholders. 

Defence Innovation Day is organised by Tehnopol through the NATO DIANA Estonian Accelerator, in cooperation with Sparkup Tartu Science Park, and supported by the Ministry of Economic Affairs and Communications, Ministry of Defence, Ministry of Foreign Affairs and the City of Tallinn. Defence Innovation Day is an official part of Estonian Defence Week. The event is held in English.
