Founder-Market Fit in European Defence-Tech

European defence-tech is expanding rapidly, but the decisive constraint is no longer the mere availability of civilian, dual-use or deep-tech capability. The harder question is whether a company can turn that capability into military adoption, institutional trust, procurement relevance, industrial integration and strategic investability.

In defence, product-market fit is filtered through operational validation, security requirements, public procurement, sovereign control, prime-contractor integration and military user confidence. This makes the composition of founding teams a strategic variable.
