Twin1 Raises $20 Million to Build Personalized AI Digital Twins for Lawyers
The San Mateo startup offers per-user AI agents that plug into workplace tools under firm-controlled governance to protect data and preserve lawyer judgment.
Overview
- Twin1 announced a $20 million Seed round to exit stealth, with the financing led by Bessemer Venture Partners alongside Tribeca Venture Partners and Aramco Ventures.
- The company is led by former Eigen CEO Lewis Liu and co‑founders Tom Cahn and Huiting Liu, drawing on the team’s prior legal‑AI experience after Eigen’s sale to Sirion.
- Twin1’s product creates an individual, continuously updated digital ‘Twin’ for each user plus an enterprise MCP server that provides a governed interface for agents to access context and take action.
- Twins operate inside common workplace tools such as Slack, Microsoft Teams, Outlook, Gmail, Google Drive, and SharePoint and the company says firms including Linklaters, Orrick, and Dechert are already using the system or running proofs of concept.
- The company emphasizes encryption, user review controls and flexible deployment models, including single‑tenant and private‑cloud options, to give firms control over data and limit reliance on any single external model provider.
