Trajectory

Trajectory is a research lab and product company building the platform for continual learning in artificial intelligence. The company's platform captures real product usage signals including user corrections, retries, edits, and rejections and uses them to continuously post-train large-scale agentic AI models, enabling those models to improve over... time rather than remain static after deployment. Trajectory's core technical unit combines what an AI agent did with how users responded, allowing companies to train on full failure chains and improve model weights, prompts, and agent workflows together. The company has raised $15 million from investors including Conviction, Bessemer Venture Partners, Radical Ventures, Jeff Dean, and Fei-Fei Li. Trajectory's team brings research experience from DeepMind, OpenAI, Apple, Meta, Amazon AGI, and Scale AI, alongside product expertise from Stripe and Figma. The company partners with AI-native companies such as Clay, Harvey, Decagon, Mercor, and Rogo to power their agentic systems in production.Read More
