What happened lately

Trajectory timeline

Trajectory announced a $45 million Series A led by Sequoia at a $300 million valuation on November 2, alongside a platform for post-training models using production data and expert standards. The company describes training, evaluation and deployment as a connected workflow.

Continual Grading and Group Size 1 are explicitly research previews. The platform announcement describes self-service training, while the reviewed homepage still directs prospective users to a waitlist. Claims about model improvement remain company claims, rather than a guarantee for every task or organization.
