MD ONE Ventures

MD ONE Ventures is a London-based venture capital firm founded in 2021, operating as Europe's dedicated national security venture capital fund. The firm invests in product-focused deep tech businesses with strong commercial foundations that have the potential to advance European and allied nations' national security capabilities. Managing approximately $200 million in AUM, the team of eight includes two partners and two venture partners who combine comprehensive VC experience across more than 12 subsectors and 150 historic transactions with operational backgrounds from Tier One Special Forces and Intelligence Communities. MD ONE leads rounds with check sizes of $10 million to $50 million, covering a wide spectrum within the defense and security universe: cyber, AI, machine learning, autonomy, robotics, drones, space, life sciences, SaaS, medtech, and communications — both software and hardware companies with national security, enterprise, and defense backgrounds. The portfolio of 21 investments includes a major pending public listing: XTEND, an AI-driven autonomous defense robotics company, announced a $1.5 billion Nasdaq listing through a merger with JFB Construction Holdings expected in mid-2026 under the ticker XTND. Other portfolio companies include Greenjets (electric propulsion for drones and aircraft, $7 million pre-Series A, December 2025), Airfinity (disease forecasting platform), Milvus Advanced (metals and minerals for defense), Pimloc, and Labrys. The firm made three investments in 2024 and four in the first half of 2025. MD ONE's cross-disciplinary team — combining VC investment expertise with firsthand special operations experience — allows it to evaluate dual-use technologies and defense applications with operational credibility that financial-only investors lack. The firm's mission is to ensure that Europe and its allies maintain technological superiority through commercially robust companies at the frontier of defense innovation.
