With the GSIS Accelerator – powered by Speer Group, the Global Security and Innovation Summit (GSIS) is launching a new innovation format designed to address Europe’s strategic security needs. The program is looking for start-ups with high-impact technologies in the fields of security, defence, and resilience. The ten most compelling applicants will be invited to present their ideas on October 22, 2025, at GSIS in Hamburg before an international audience of top-tier decision-makers.
Equity investments of up to EUR 5 million per start-up may be made available to the winners of the final presentation, subject to internal investment criteria, a successful due diligence process, and standard contractual negotiations. These investments will be provided by the GSIS exclusive Venture Partner, Speer Group.
The GSIS Accelerator connects founders with investors, policymakers, and institutions in the security policy space – with a clear objective: to close Europe’s security innovation gaps through targeted support. In addition to pitching their ventures, finalists will benefit from access to an international network and advisory support on core governance issues in the security domain.
“Technology and Innovation are crucial factors for European security. The Accelerator combines start-up intelligence with strategic relevance - exactly what Europe needs now.” – Dr Bastian Giegerich, Director-General of IISS
“With GSIS and the Accelerator, we are creating a unique meeting point for innovation, responsibility, and execution – right in the heart of Europe. Hamburg offers the ideal stage for it.” – Heiko M. Stutzinger, CEO of Hamburg Messe and Congress GmbH
“We don’t invest in trends, we invest in solutions that strengthen Europe’s security and resilience. Alongside capital, we provide access to strategic networks and experts who help companies scale and secure Europe’s capacity to act.” – Max Büchner, CEO of Speer Group
“Europe cannot afford to fall behind in the strategic race for technology. The GSIS Accelerator creates a platform where security-relevant innovations become visible, investable, and politically connected.” – Dimitrios Argirakos, Executive Chair of GSIS
Finalists will be selected by Speer Group as the investment manager, in collaboration with experts in security policy, technology, and venture capital via the Investment Recommendation Committee. Selection criteria include the degree of innovation, strategic relevance, and scalability.
In addition to exposure and access to an international network, winners will have the opportunity to secure financial backing. The program seeks technology-driven start-ups aligned with NATO’s five strategic dimensions: sea, air, land, cyber (intelligence), and space, along with complementary technologies.
Pitch decks are accepted via email until October 10, 2025. The live pitch of the finalists will take place on October 22, 2025, at GSIS at the CCH – Congress Center Hamburg. The aim: to spotlight and support Europe’s most security-relevant start-ups.
