About usTrajectory is a research and product lab creating the platform for continual learning.
AI is the most capable software ever built, and the least able to learn. Every valuable correction and edit that happens in a product evaporates at the next session. A few teams have closed this gap by hand-coupling their models to their products: Composer, Claude Code, Windsurf SWE-1.
Trajectory is the first scalable approach for every company: our platform unlocks the signal already sitting in product use, so companies can continuously post-train large-scale agentic models that outperform the frontier.
Our research team comes from Deepmind, OpenAI, Meta Superintelligence, and product team from Figma, Apple, Stripe, and Windsurf. We're working with customers like Harvey, Rogo, Mercor, Decagon and Clay, and we've raised 60M from Sequoia, Conviction, Jeff Dean, and Fei Fei Li.
