Trajectory Launches Continual-Learning AI Platform, Raises $15 Million Seed
Trajectory, a startup founded by researchers from DeepMind, Apple, Meta Superintelligence Labs and OpenAI, said it has raised a $15 million seed round from Conviction, Bessemer, Radical Ventures, Jeff Dean, Fei-Fei Li and others. The company is launching a continual-learning platform that uses signals from product usage to continuously post-train large-scale agentic models for companies.
Trajectory’s pitch is that enterprise AI models should improve from real-world usage rather than remain static after deployment. The company said it is working with customers including Clay, Harvey, Decagon, Mercor and Rogo, with some systems already in production; Baseten said the setup has supported live A/B tests since April 2026, and Wired reported the financing valued Trajectory at $115 million.

@rronak_Today, @MichaelElabd, @QuantumArjun, and I are excited to announce Trajectory. We are a research lab and product company building the platform for Continual Learning. Our platform unlocks the signal already sitting in product usage, so c
@rronak_We’d like to thank everyone who has backed us and helped get to where we are today: @Conviction, @BessemerVP, @radicalvcfund, @svangel, @_geniusventures, @ExceptionalCap, @Antifund, @EssenceVenture, along with angels @JeffDean, @drfeifei, @
@rronak_Trajectory is on a mission to enable Continually Learning systems for every company. Learn more about our plan to do so:
@togethercomputeThe best research labs are building what comes after static models. Congrats to @trajectorylabs on the launch! Excited to have them training on the AI Native Cloud as they push the frontier on Continual Learning!
@basetenMost enterprise AI models stay static after deployment, forcing teams to rely on endless prompt tweaking. This is the problem Trajectory AI is solving. Their continual learning platform enables companies to deploy custom models that improv
@basetenExcited to support the @trajectorylabs team as their inference partner. Powering live, continuous post-training for frontier-scale models takes serious infrastructure, and we're thrilled to build the future of continual learning together.
