Twin Prime is a frontier AI laboratory developing specialised multimodal models that reason natively across the sensor modalities used in defence and national security settings. Founded in 2025, the company works on sensor fusion, real-time inference and perception-to-decision systems, with the aim of shortening the interval between detecting a threat and acting on it. Its models are built to process data from a large number of sensor types and to support real-time decision-making against threats.
The work spans several demanding technical areas: multimodal AI, multi-sensor reasoning, real-time inference at the frontier of model development, and applied defence AI. The engineering and research team is multinational, recruited from leading frontier model companies and from quantitative finance. The company describes itself as mission-driven, with a stated focus on the defence of democracies and the security of societies.
Twin Prime is headquartered in New York City and is expanding its operations in Athens, Greece. It raised $10m in pre-seed funding, led by Expeditions, with participation from Theon International, American and European investors and family offices. The company operates across the defence, national security and intelligence verticals.
