The San Mateo-based startup, founded in 2025, pairs every professional with an AI-powered digital twin that scales their expertise across an organisation.
What's the endgame? Twin1Dealroom has a profile for this one. Try Dealroom → is building what it calls the coordination and trust layer for enterprise AI. Each twin is grounded in a user's work context — emails, meetings, documents, and workplace systems — and operates inside tools such as Slack, Microsoft TeamsDealroom has a profile for this one.

The product: The platform gives each person a continuously evolving model of their knowledge and judgment that can answer questions and act on their behalf. Six layers of privacy and governance controls decide when information is shared, while a Twin Network lets individual twins coordinate work without overriding human control.
Why it matters: "In every knowledge organization, the human is the atomic unit of knowledge," said co-founder and chief executive officer Dr. Lewis Liu. "Twin1 gives every professional a digital twin that preserves and amplifies their knowledge, judgment and voice, while keeping privacy, permissions, and human agency at the core."
What could go wrong? The pitch hinges on trust. Persuading enterprises to let an AI act on employees' behalf — and share permission-aware knowledge across teams — is a governance and adoption challenge, however tight the controls.
By the numbers: The startup has deployed with partners across legal, financial services, and energy for over a year. Customers — including law firms LinklatersDealroom has a profile for this one.

The funding will expand teams in San Mateo and London, fund go-to-market, and develop the core technology.
The signal: At $20 million, Twin1's seed sits in the top 1% of all enterprise software seed rounds on record. That scale reflects investor appetite for AI that layers onto knowledge work rather than replacing it — betting expertise can compound instead of, as Liu puts it, "collapse into the average."
