Twin Prime

About Twin Prime

Twin Prime is a U.S.-based artificial intelligence laboratory founded in 2025 that develops specialized AI models for the defense and security sectors. The company focuses on creating AI that can process and reason with data from a wide array of sensor modalities used in physical world security and defense operations, enabling operators to act with urgency and effectiveness. The founding team includes George Lentzas, Stephane Sezer, Drew Calcagno, and Michael Leite-Garcia, who possess experience from organizations such as Google Research, Hudson River Trading, and Lawrence Livermore National Laboratory, as well as various U.S. and European military branches. This technical and operational background provides the firm with credibility in developing solutions for sensitive and complex defense applications. In May 2026, Theon International Plc, a defense technology company, announced a $3 million strategic investment in Twin Prime, acquiring a single-digit minority equity stake. Concurrently, the two companies agreed to form a joint venture in Greece, with Theon holding a 60% ownership and Twin Prime 40%. This joint venture is designed to develop, commercialize, and deploy bespoke AI solutions built on Twin Prime's proprietary platform, complementing Theon's existing R&D and accelerating its AI initiatives. Twin Prime was also concluding a pre-seed funding round led by Expeditions, a European early-stage investor focused on security and deep tech startups. It is important to note that a different startup also named Twin Prime, which focused on machine learning for mobile app performance, was acquired by Salesforce in 2016. That company, founded by Kartik Chandrayana, is unrelated to the current AI defense lab.
