Best Defence Conference 2026

London / Canada

Best Defence is the most accessible entry point into Ontario's defence-industrial ecosystem — Canada's largest — offering direct, affordable face-time with CAF procurement officers, federal/provincial decision-makers, and prime contractors at a fraction of the cost of CANSEC or major trade shows. For SMEs and startups, the Technology Showcase provides a curated on-stage pitch opportunity directly in front of CAF and government buyers. The ODA's official backing adds institutional credibility and a growing member network, making it a high-ROI event for companies seeking Canadian programmes of record or teaming partners.

Defense PPM Summit | London 2026

London / United Kingdom

With European defence budgets at historic highs, programme and portfolio management professionals face acute pressure to deliver capability faster and with greater governance rigour — making this one of the few senior forums specifically dedicated to defence PPM execution rather than technology or procurement. The deliberately small delegate cap (80) means decision-makers — not mid-level attendees — fill the room, creating high-density networking with programme directors and PMO heads who control major delivery budgets. For PPM-tooling vendors, digital-engineering firms, and consulting SMEs, it is a rare access point to the European defence programme leadership tier without the noise of a large trade show.

DIANA Demo Day

London / United Kingdom

Concentrated room of NATO end users and dual-use investors. For investors it is curated deal flow; for founders it is a warm introduction to alliance customers.

International Dismounted Soldier Conference

London / United Kingdom

For defence SMEs and suppliers, IDS is one of the few niche forums where procurement decision-makers, programme offices (including DE&S and allied equivalents), and NATO representatives discuss active capability gaps and acquisition priorities in a small-group setting — making it highly efficient for business development and shaping bids. Co-location with the Uncrewed & Autonomous Systems conference in 2026 broadens the addressable audience to include the fast-growing autonomy and UAS procurement community. The early-bird deadline and tiered partnership packages make it accessible to smaller companies seeking thought-leadership or exhibition exposure alongside primes.

Uncrewed & Autonomous Systems 2026

London / United Kingdom

With 250+ senior defence, government, and industry representatives attending, this is one of the UK's most focused annual forums for UGV and UAS procurement discussions, making it a direct channel to British Army, NATO, and allied acquisition decision-makers. SMEs and technology startups can access dedicated exhibition and roundtable partnership slots that place emerging autonomous solutions in front of programme managers and capability developers. The co-location with International Dismounted Soldier amplifies cross-domain relevance for suppliers covering soldier systems, robotics, and human-machine teaming.

Counter UAS Technology Europe

London / United Kingdom

With only ~300–350 vetted attendees, the event offers unusually direct access to the military end-users and procurement decision-makers who write C-UAS requirements and sign contracts across NATO and European allies — making it an efficient entry point for SMEs and startups seeking early programme engagement. The tightly controlled attendance (registrations subject to organiser approval) signals a senior, buying-intent audience rather than a broad trade-fair crowd. For suppliers, sponsorship or exhibition here delivers visibility at the moment when European C-UAS budgets and multi-nation frameworks are being actively shaped.

NATO DIANA Challenge Call

London / United Kingdom

DIANA is NATO's primary mechanism for pulling dual-use deep-tech startups and SMEs directly into the Alliance's procurement and capability pipeline via its Rapid Adoption Service, substantially compressing the typical 3–5 year procurement cycle to 6–12 months. Selection places a company within a trust network spanning 32 Allied markets, military end-users, and a NATO-linked investor community — a credibility signal that is exceptionally difficult to replicate commercially. For defence-adjacent startups, the non-dilutive funding structure (no equity taken, full IP retained) and access to live operational test environments make this one of the most commercially consequential accelerator programmes in the transatlantic defence ecosystem.
