Deborah Fairlamb is a Founding Partner at Green Flag Ventures, a venture capital firm co-founded in 2023 with Justin Zeefe that focuses on Ukrainian defense and dual-use technology. After over a decade in Ukraine’s startup ecosystem and prior Wall Street experience at UBS and Merrill Lynch, she now leads investments in battlefield-proven tech. Her investment thesis targets early-stage Ukrainian companies in dual-use, defense, AI, machine learning, cybersecurity, fintech, and greentech, with a strict definition of dual-use requiring clear markets in civil, military, and commercial sectors. Typical check sizes range from $100,000 to approximately $1.2 million, and the fund plans 12–20 investments over three to five years. Notable portfolio companies include Swarmer, HIMERA, Teletactica, Falcons, Kara Dag Technologies, and Astra Nav, which develops M-GPS navigation technology. Fairlamb emphasizes that “innovation is key to victory in Ukraine” and views dual-use tech as a bridge between Ukrainian and U.S. markets, aiming to scale battlefield solutions to NATO and Fortune 500 customers.
