National · United Kingdom · HM Government with the British Business Bank
NSSIF, established in 2018, is the UK Government's corporate venture arm for dual-use deep tech, run as a partnership between the national security and defence community and the British Business Bank. It invests through British Patient Capital and the Enterprise Capital Funds programme, and directly via British Technology Investments Ltd. Priority themes are AI and data, quantum, semiconductors and advanced compute, space and communications, and emerging technologies. Under the 2025 industrial strategy it was awarded up to £330 million to invest across FY2026-27 to 2029-30.
It is patient government-linked equity that also opens doors into the UK national security customer base, without a grant competition cycle. Relevant for dual-use deep-tech companies raising Seed to Series B alongside commercial VCs.
Danish Ministry of Defence / Danish Ministry of Defence Acquisition and Logistics Organisation (FMI/DALO)
The single largest pot of near-term Danish defence procurement money, with an explicit invitation for industry to propose what to buy. Speed to fielding is the main selection criterion.
German Federal Government (BMVg and BMI)
One of very few German vehicles paying companies directly for security and defence-relevant research, with multi-million-euro phased contracts. Procurement-law process means longer lead times; watch the partnering events.
