Overview

Paxton AI is a generative AI legal assistant built to help law professionals with regulatory research, drafting, and staying current on regulatory change. The company was founded in 2023 by Michael Ulin and Tanguy Chau, raised a 6 million dollar seed round that September, and closed a 22 million dollar Series A in January 2025 led by Unusual Ventures.

The assistant automates legal and regulatory research and drafts documents such as research memos, client emails, and legal briefs, and it can build a firm-specific knowledge base from uploaded documents to create a chatbot grounded in a firm's own files. Paxton has been recognized as a 2024 ABA Techshow winner and a Law.com New Law Company of the Year finalist.

Paxton AI serves law firms and in-house legal and compliance teams that need faster research and drafting without sacrificing citation accuracy. Individual access costs $499 per user per month, or $2,999 billed annually for roughly half the monthly cost, with a custom Enterprise tier and a 7-day free trial available.
