About Neomatter
Summary
Neomatter builds an AI layer for in-house legal teams that intercepts requests from across a company before they reach counsel. It connects to email and messaging tools, reads incoming documents, checks the team's playbooks and past deals, and delivers a completed analysis with a recommended response for the lawyer to approve. The product replaces the intake, research, and first-draft work that in-house attorneys otherwise do themselves.
Go-to-market
In-house legal teams at companies are the buyer; teams start by booking a demo and connecting Neomatter to existing tools like Gmail, Outlook, Slack, and Teams with no forms or custom intake required.
