Twin Prime Raises $10M for AI in Defence

Twin Prime, a frontier AI lab specializing in the defence and security sector, has announced it has raised $10 million in a pre-seed funding round. The round was led by Expeditions, with additional investment from American and European VCs, Theon, family offices, and angel investors from companies such as Palantir, Anduril, and Quorum. This significant initial capital underscores the growing interest in highly specialized artificial intelligence solutions designed to address the complex and high-stakes challenges of the national security landscape.

Founded in 2025 by George Lentzas, Stephane Sezer, Drew Calcagno, and Michael Leite-Garcia, Twin Prime leverages a multinational team of researchers with extensive experience in frontier AI, quantitative finance, and national security. The founders boast backgrounds at prominent institutions such as 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, bringing a unique combination of technical and strategic expertise to the project.

Twin Prime's Innovative Approach to AI for Security

Twin Prime's primary objective is the development of AI models capable of natively reasoning on data from a large number of sensor modalities in the physical world. This capability is crucial, particularly in the national security context, where the speed and accuracy of decisions can have critical implications. The company aims to compress the perception-to-decision layer, enabling smart, real-time action against threats.

Mikolaj Firlej, Co-founder and General Partner of Expeditions, highlighted how current AI models are often not specialized enough to capture the complexity of modern warfare and broader security challenges. These models, according to Firlej, usually have limited applicability at the edge and often overlook sensor integration and critical data feeds. Twin Prime, in contrast, is developing models purpose-built for high-stakes environments where size, fusion, and speed are critical factors, presenting clear commercial value not just by retrofitting legacy systems, but by transforming their operations.

Implications for Deployment and Data Sovereignty

The nature of Twin Prime's applications, focused on defence and national security, implies stringent requirements in terms of deployment and data management. The need to operate in high-stakes environments and the mention of applicability at the edge suggest a strong orientation towards self-hosted or on-premise solutions. In these contexts, data sovereignty, regulatory compliance, and the ability to operate in air-gapped environments become critical factors for ensuring the security and integrity of operations.

Further confirmation of this practical, deployment-oriented approach is the intention of Twin Prime and Theon, a large European defence prime, to form a Joint Venture. This collaboration aims to develop, commercialize, and deploy bespoke AI solutions built upon Twin Prime's proprietary models. The Joint Venture is set to augment Theon’s extensive deployment of sensors and other defence product offerings, particularly as a continuation of its Theon Next initiative, strengthening the ability to integrate AI directly into existing and future infrastructures.

Market Context and Future Prospects

The defence and security sector is undergoing rapid evolution, with artificial intelligence playing an increasingly central role. The ability to process large volumes of data from diverse sensors and make rapid decisions is fundamental to maintaining a strategic advantage. Twin Prime positions itself as a key player in this scenario, offering solutions that go beyond the generic capabilities of current LLMs, providing specific tools for military and security needs.

The investment in Twin Prime reflects a broader trend in the tech market, where specialization and the ability to address complex problems in critical sectors are highly valued. The combination of an experienced team, solid funding, and a strategic partnership with an established player like Theon, positions Twin Prime for significant impact in the defence AI landscape, promising to transform operations through targeted technological innovation.
