The GSIS Accelerator – powered by Speer Group, launched by the Global Security and Innovation Summit (GSIS), is a new innovation initiative directly addressing Europe’s strategic security needs. The programme seeks high-potential start-ups offering relevant solutions in defence, resilience and emerging security technologies. The top ten applicants will pitch live at GSIS 2025 in Hamburg on 22 October – in front of a curated audience of global decision-makers.
Selected finalists may receive up to €5 million in equity funding per start-up, provided through Speer Group investment vehicles and subject to internal due diligence.
The GSIS Accelerator connects founders with investors, policymakers, and strategic institutions – aiming to close Europe’s innovation gaps in security through focused, scalable support. In addition to the live pitch, finalists will benefit from strategic mentoring, expert advice, and access to a high-level international network.
