Trajectory raises a $40M Series A round

Trajectory is a San Francisco-based AI infrastructure startup founded by former researchers from Google DeepMind and Apple. The company has developed a self-service platform that enables businesses to continuously update their AI models using real-world user corrections and edits. Using a technique called self-distillation policy optimization, Trajectory automates the process of model refinement without requiring manual data curation or retraining by research teams. The platform allows companies to improve their models as frequently as weekly based on production data.
