AI security startup White Circle has secured $11 million in seed funding to develop a real-time control layer for enterprise AI applications. The Paris-based company aims to address issues such as uncontrolled model outputs and sensitive data leaks by deploying a monitoring system between users and AI models. This system can block or flag unauthorized actions, enhancing safety in business environments. Key investors include Romain Huet from OpenAI and Thomas Wolf from Hugging Face. White Circle plans to use the funds to expand its team and accelerate product development, targeting markets in the US, UK, and Europe. The company, founded by Denis Shilov, has processed over one billion API requests and serves clients in fintech and legal sectors. Additionally, White Circle is conducting research on AI model biases, revealing potential risks in high-stakes scenarios.
