Niels Carlsen is a founding partner and investor focused on early-stage modern defence, space and cyber tech, currently leading fundraising for Final Frontier Fund II after closing a 4.5mEUR, 50%-oversubscribed first fund. With a PhD and MSc in Software Engineering from DTU and more than 15 years of international operational tech experience, he blends deep technical understanding with hands-on startup building—from CTO roles in early internet ventures to leading investments at Seed Capital since 2007. He has a proven track record backing and scaling major Nordic startups (early investor in Trustpilot; board roles at Vivino, Lunar, Dixa and many others) and routinely helps founders attract international capital. Niels combines venture-sourcing instincts with product and engineering empathy, advising accelerators like ESA BIC Denmark and Defence Builder on strategy and commercialization. An adventurous problem-solver, he once captained a two-year family circumnavigation by yacht—a leadership experience he likens to founding a startup. Based in Copenhagen, he now focuses on dual-use space and defence deeptech where commercial scale meets national security impact.
