Green Flag Ventures is a US-based venture capital firm investing in early-stage Ukrainian startups developing dual-use, defense, artificial intelligence, and cybersecurity technologies. The firm focuses on companies building solutions in AI-driven autonomy, resilient communications, RF counter-UAS systems, and next-generation navigation.
The firm's investment thesis centres on technologies validated through real-world battlefield conditions. It emphasises that "defense needs tomorrow's tech today" and positions itself as placing capital on the frontline to identify and scale proven solutions. Green Flag Ventures sources Ukrainian startups whose products have been tested in operational environments, then works to establish market access with allied governments and commercial buyers by converting battlefield performance into sustained demand.
The firm's stated mission is bridging front-line technology to western markets, enabling Ukrainian innovations to become market leaders globally. Its investment approach relies on battlefield data advantages for training AI models and leverages war-tested iteration cycles to derisk product-market fit before broader commercialisation.
