An informal opening reception on 15 June 2026 at La Felicita, Paris, launching NATO DIANA's two-day International Demo Days. It gathers investors, defence stakeholders, government representatives and the accelerator's 2026 dual-use deeptech cohort ahead of the next-day demonstrations.
The Opening Reception is the first day of NATO DIANA's International Demo Days 2026, a two-day event held on 15 and 16 June in Paris. DIANA, the Defence Innovation Accelerator for the North Atlantic, uses the evening to introduce the dual-use deeptech startups of its 2026 cohort to investors, defence stakeholders, government representatives and industry leaders. The reception runs from 18:30 to 22:30 at La Felicita, 5 Parvis Alan Turing, in the 13th arrondissement.
The reception opens a programme that continues on 16 June with innovator product demonstrations, structured networking and an off-site live demonstration hosted by the French Army General Staff. The evening itself is an informal gathering with light food and drinks, designed for early connections ahead of the demonstration day. Registration was application-based and closed on 5 June 2026.
The event runs on 15 and 16 June, immediately before VivaTech's business days, positioning defence and dual-use technology at the start of the Paris tech week. It belongs to the cluster of curated, approval-based gatherings that frame the show rather than to the open show floor.
No conference programme or named speakers are published for the reception itself.
It is a side event taking place during the VivaTech week, on 15 June, the evening before VivaTech's business days open. It is organised by NATO DIANA and is independent of VivaTech ticketing.
DIANA is the Defence Innovation Accelerator for the North Atlantic, a NATO body that accelerates dual-use deeptech startups across the alliance. The Demo Days showcase the startups selected in its accelerator programme.
It is not designed for: the general public, as access is application-based and closed; attendees with no link to defence, dual-use technology or its funding; those seeking a conference programme, since the evening is a reception; and late registrants, since applications closed on 5 June 2026.
La Felicita is a large food and event venue at 5 Parvis Alan Turing, 75013 Paris, in the Station F district. Its scale and central-east location suit a standing reception. The site sits within the Paris Rive Gauche area, served by metro and RER at Bibliotheque Francois Mitterrand.
DIANA is NATO's defence innovation accelerator, running cohorts of dual-use deeptech startups across allied countries with test centres and accelerator sites. The International Demo Days are its showcase moment, presenting cohort companies to investors and defence stakeholders. Event delivery is handled by the agency OFCORES.
