What Perceptron ML does
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.

Company
Perceptron ML
We make law firms AI-native.
We build AI systems specifically for law firms. Our product plugs into a firm's private environment and learns from their own matters to automate things like timekeeping, intake and matter monitoring, research, discovery, and drafting. Every answer our models generate is grounded and double-checked: facts are verified against a primary source before being cited. Law firms want that because generic legal AI keeps getting facts wrong, and they need reliability to trust it with real work.
We live in San Francisco, CA, and the company will be based here after YC.
Law firms willing to go AI-native are mostly in the US, and we're in San Francisco where AI talent and early adopter clients are concentrated.
