Twin Track Ventures

Twin Track Ventures is a London-based pre-seed venture fund founded in 2024 by Nicola Sinclair, a former Royal Air Force officer and Europe's only solo GP with a track record in the business of defence. The fund backs dual-use deep tech startups — those developing foundational technology that strengthens NATO and its allies while scaling across commercial markets. Investment focus areas include compute, communications, sensors, and supply chain (covering manufacturing, materials, and energy). The fund targets pre-seed and seed-stage companies from across NATO nations, with particular emphasis on the UK, EU, Nordics, and Balkans. It completed a £5M first close in late 2025, backed by the NATO Innovation Fund and Allocator One, and is targeting a £10M final close. Twin Track plans to back up to 25 startups with cheques of up to £500K. Founders can pitch via a form on the homepage. The fund's value-add centres on warm introductions to defence customers and guiding founders through dual-track commercialisation — converting defence traction into broader commercial scale.
