D3 Ventures

D3 Ventures is a venture capital firm specializing in early-stage investments in defense technology startups. The firm focuses on companies developing innovative solutions in areas such as unmanned systems, robotics, electronic warfare, mine clearance, artificial intelligence, and cybersecurity. D3 Ventures aims to strengthen democracies worldwide by supporting the development and scaling of cutting-edge defense technologies.

Established in 2023, D3 Ventures operates with a global perspective, investing in startups from Ukraine, the United States, Denmark, and other allied countries. The firm offers initial investments ranging from $125,000 to $300,000, with the potential for follow-on funding up to $750,000 in subsequent financing rounds. In addition to capital, D3 Ventures provides a tailored support program that includes mentorship from global experts, assistance with customer and product development, and expedited access to state actors.

D3 Ventures has demonstrated a strong commitment to fostering innovation in the defense sector. In July 2025, the Danish state-owned Export and Investment Fund (EIFO) invested $5 million in D3 Ventures, marking the first state-backed investment into the fund. This partnership underscores the growing European recognition of Ukraine's defense tech capabilities and the importance of international collaboration in advancing defense technologies.

D3 Ventures' investment strategy emphasizes the importance of a dedicated and passionate team, scalable and agile research and development processes, and products that meet the current needs of end-users. The firm seeks to bridge the gap between Ukraine's growing expertise in asymmetric defense and its allies, connecting startups with the capital and partnerships needed to scale frontier technologies. By supporting these startups, D3 Ventures aims to enhance national security and contribute to the collective defense capabilities of democratic nations.
