Twin1 AI

Twin1 gives every professional an AI-powered digital twin that scales their expertise while keeping their knowledge their own. Your Twin is grounded in the work you already do: email, meetings, documents and workplace systems. It answers on your behalf, drafts in your voice, and finds knowledge across the business, so colleagues stop waiting and experts stop being bottlenecks. Control sits with the individual. Six interlocking layers of AI governance combine inherited permissions, rules-based controls and human approval, so information is shared only when authorized. Nothing sends without you. Twins work where work already happens, across Slack, Microsoft Teams, Outlook, Gmail, Google Drive and SharePoint. Twin1 works with leading organizations across legal, financial services and energy, including Linklaters, Orrick, Dechert and Aegis Energy. Founded in 2025 by the team behind Eigen Technologies, with teams in San Mateo and London. Book a demo at twin1.ai
