Polygraf AI is an Austin-based company developing an enterprise AI security platform powered by proprietary small language models. Its locally deployed modules require as little as 8 GB of RAM and a 1.3 GHz CPU, enabling organizations to identify deepfake attempts, uncover insider risks, and maintain the integrity of sensitive intelligence. The system is designed for mission-critical environments in defense, financial services, insurance, and healthcare, sectors where the company reports rapid adoption over the past year. By operating on modest hardware, Polygraf AI aims to make advanced AI threat detection accessible without expensive cloud or GPU resources. The company plans to expand its product suite and enhance R&D to address broader enterprise, defense, and intelligence use cases. Newly raised capital will also support go-to-market initiatives to deepen penetration in these target verticals. No revenue or user figures were disclosed in the article.
