Corolair SAS, operating under the brand Raison, is a Paris-based edtech company developing AI-powered teaching assistants for educational institutions and corporate training programs. Founded by CEO Thomas Sartori, an ESSEC Business School graduate, the company focuses on integrating AI tutors into existing learning management systems like Moodle, Blackboard, and Canvas. Raison's platform offers features such as SCORM parsing, grading automation, and learning analytics, positioning itself as a middleware layer between traditional LMS infrastructure and generative AI capabilities.

The company targets both higher education institutions seeking to improve student outcomes and corporate L&D departments aiming to scale training programs.
