Twin Track Ventures

Twin Track Ventures is a London-based venture capital firm that specializes in backing deep tech startups. The firm focuses on companies developing technologies with dual-use applications, serving both commercial and defense & security customers. They primarily invest in pre-seed and seed rounds, seeking out IP-rich technologies that have the potential to transform these markets. Twin Track Ventures is particularly interested in founding teams from across NATO countries.

The firm was founded in 2024 by Nicola Sinclair, an 18-year veteran of the British Air Force. Sinclair established Twin Track Ventures to create a specialized investment platform for startups developing dual-use technologies, drawing on her extensive experience in national security, venture capital investing, and science-led startups. Prior to launching Twin Track Ventures, she led the Royal Air Force's venture capital arm, the Air Innovation Fund, which focused on pre-Series A startups with dual-use technologies in areas such as energy, future compute, and hypersonic flight. The firm successfully completed its first close of £5 million, with backing from institutional investors including the NATO Innovation Fund and Allocator One.

Twin Track Ventures has already made several investments in early-stage companies. Notable portfolio companies include Hadean, Cassi AI, and SE3 Labs. The firm prioritizes technologies across compute, communications, sensors, supply chain, manufacturing, materials, and energy. They aim to invest in approximately 25 early-stage companies across NATO countries, with individual investment sizes ranging from £150K to £500K.

The team's expertise is rooted in defense, science, and early-stage investing. Nicola Sinclair's background in the Royal Air Force and her experience leading a venture capital arm within the armed forces provide Twin Track Ventures with a unique understanding of the defense and security sectors. This specialized knowledge allows the firm to effectively connect early-stage founders with decision-makers in defense and security, helping startups navigate the complexities of government contracts and accelerate their commercial trajectory.
