Twin1 AI has exited stealth with $20 million in seed funding for digital twins that carry a worker’s expertise across an organization. Bessemer Venture Partners, Tribeca Venture Partners and Aramco Ventures co-led the round, which also drew Orrick as a strategic investor and angels including Wiz co-founder Roy Reznik.
Founded in 2025 by Lewis Liu, Tom Cahn, Huiting Liu and Jonathan Budd, the San Mateo startup pairs each employee with a persistent model of their knowledge, judgment and context. Three of the four founders come from Eigen Technologies, the London document AI company that sold to SirionLabs in 2024, and Liu led Eigen through that sale.
Each twin reads email, meeting notes, documents and connected workplace systems, then operates inside Slack, Microsoft Teams, Outlook, Gmail, Google Drive and SharePoint. The owner decides what the twin may read and who may query it; six layers of policy and AI controls sit over every request. A Twin Network layer helps twins find the right colleague and hand work between teams, and an enterprise Model Context Protocol server lets outside agents pull governed context.
The platform has run for more than a year with legal, financial and energy clients such as Linklaters, Orrick, Dechert, Customers Bank and Aegis Energy. Twin1 says the system absorbs 30% to 50% of the communications load its customers’ knowledge workers would otherwise carry.
The cash funds hiring in San Mateo and London, sales and a pipeline the company says exceeds 400 prospects, with a self-service product planned for smaller firms.
