$15 million seed round, valuation surpassing $100 million, this data-driven flywheel story truly resonates with investors

Trajectory is a continuous learning platform that advocates transforming each user correction into a reward signal to achieve online, ongoing model updates. By executing trajectories and telemetry signals, it stitches together tool calls, reasoning steps, and user feedback into fine-tunable data, and connects with platforms like LangSmith. It has completed $15 million in seed funding, with a valuation of approximately $115 million. Investors include Conviction, Bessemer, Radical, BoxGroup, and individual investors such as Jeff Dean and Fei-Fei Li. The current system still relies on offline periodic fine-tuning and has not yet achieved real-time learning with each interaction.
