Trajectory has raised $40 million in a Series A round led by Sequoia Capital, with Nvidia and Bessemer Venture Partners joining. The deal values the San Francisco company at $300 million.

What makes the round stand out is how quickly it followed the last one. Trajectory announced a $15 million seed at a $115 million post money valuation only two months earlier. The valuation has since roughly tripled.

The company describes itself as a research and product lab and is led by chief executive Ronak Malde. Its focus is continual learning: a platform meant to help AI native companies move past static models toward systems that improve with every user interaction. The founding team came out of DeepMind, Apple, OpenAI and Meta Superintelligence Labs.

Beyond the lead investors, Trajectory’s backer list includes Bessemer Venture Partners, Radical VC and BoxGroup, along with angel investors Jeff Dean and Fei-Fei Li and founders from Notion, Dropbox, Braintrust and Hugging Face.

The California lab helps businesses customize open source models, putting it in a part of the AI infrastructure market that investors have been willing to price aggressively this year.
