Expeditions leads $10M pre-seed round for Twin Prime, the frontier lab building AI models for defense and security
- Twin Prime is a frontier AI lab dedicated to the defense of democracies and security of societies, backed by leading defence investor, Expeditions.
- Twin Prime’s custom models will reason on data from the many sensors active across the national security landscape to enable operators to act effectively and in real time against threats.
- Twin Prime raised a $10M pre-seed round, led by Expeditions, with additional investment from a range of American and European VCs, family offices, top angels across the industry, and defense manufacturer Theon.
WARSAW / LONDON, 14 May 2026: Expeditions today announces its lead investment into Twin Prime, a frontier AI lab building specialised models for defense and security, who have raised $10M in pre-seed funding, with additional investment from American and European VCs, Theon, family offices, and angels from within Palantir, Anduril, Quorum, and more.
Twin Prime is a new frontier AI lab dedicated to the defense of democracies and security of societies. Twin Prime is developing AI models that natively reason on data from the large number of sensor modalities in the physical world, notably across the defense and security landscape, to enable operators to act urgently and effectively.
Twin Prime was cofounded in 2025 by George Lentzas, Stephane Sezer, Drew Calcagno, and Michael Leite-Garcia, a multinational team of researchers in frontier AI, quantitative finance, and national security. Collectively they have extensive experience at top institutions including Hudson River Trading, Google Research, Lawrence Livermore National Laboratory, Columbia University, the White House, the Pentagon, and various branches of both the US and European armed forces.
Mikolaj Firlej, Co-founder and GP of Expeditions, said: “Current AI models are not specialised enough to capture the complexity of modern war and wider security challenges. They usually have limited applicability on the edge and they often miss sensor integration and critical data feeds. Twin Prime is developing models purpose-built for high-stakes environments where size, fusion and speed are critical. At a time when most defence prime contractors struggle to integrate advanced AI models, the Twin Prime team presents a clear commercial value not just by retrofitting legacy systems, but transforming their operations.”
Twin Prime and Theon, a large European defence prime, also intend to form a Joint Venture to develop, commercialize, and deploy bespoke AI solutions built upon Twin Prime's proprietary models. The JV will augment Theon’s extensive deployment of sensors and other defense product offerings, particularly as a continuation of its Theon Next initiative.
