Perceptron ML on the record

What they shipped

  • From its YC profile: We build AI systems for law firms, trained on each firm's own matters and deployed privately in their environment: timekeeping, intake and matter monitoring, research, discovery, and drafting. Our grounding engine verifies every fact against a primary source before a model can cite it, which is why firms trust us with work that off-the-shelf legal AI keeps getting wrong. (source)
  • Its own site describes it as: "AI software built for law firms. We design and build bespoke systems, trained on your matters, deployed in your environment, grounded in verified sources." (source)

Who is behind it

  • Michael Marcotte, Founder/CEO: Founder at Perceptron ML (YC S26). Previously AI Research at NVIDIA, where he built production AI agents for hardware debugging and formal verification. Holds BS in Mathematics and MS in Computer Science from Stanford. (source)
  • Peyton Marcotte, Founder/CTO: Founder at Perceptron ML (YC S26). Previously founded PMARC, developing astronaut exercise equipment for long-duration spaceflight (supported by NASA, Brown University, and 1517 Fund grants). Studying Mechanical Engineering at Brown. (source)
