Twin1 is a privacy-first AI platform that gives every professional an AI-powered digital twin to scale their expertise while keeping their knowledge their own. Grounded in the work professionals already do — email, meetings, documents, and workplace systems like Slack, Microsoft Teams, Outlook, Gmail, Google Drive, and SharePoint — each Twin answers on its owner's behalf, drafts in their voice, and surfaces knowledge across the organization, reducing bottlenecks and freeing colleagues from waiting on individual experts. Control remains firmly with the individual: six interlocking layers of AI governance combine inherited permissions, rules-based controls, and human approval, ensuring information is shared only when authorized and nothing sends without explicit consent. Founded in 2025 by the team behind Eigen Technologies, with offices in San Mateo and London, Twin1 already works with leading organizations across legal, financial services, and energy.
