Twin1 has come out of stealth with a $20m Seed round co-led by Bessemer Venture Partners, among others, to develop digital twins for lawyers. It’s captained by Lewis Liu, the former CEO of Eigen – which was sold to Sirion, (see AL interview with Liu in following article). The founding team also includes Tom Cahn and Huiting Liu, both ex-Eigen staffers.
It’s based in San Mateo, California, with another office in London. Law firms such as Linklaters, Orrick, and Dechert have already been using it, and AL is aware of a ton of POCs among other law firms and also corporates.
The digital twins that it develops are ‘an AI extension’ of yourself. Or, as they say: ‘Twin1 is a fully-encrypted in-platform agent that knows everything you know, responds on your behalf, and acts as an AI version of you to the extent you decide. Helping you skip bottlenecks, locate key information, and network with other Twins so you get the right answers fast.’
‘The digital twins are grounded in the user’s work context, including emails, meetings, documents, and workplace systems.
‘These digital twins operate where professionals work across tools such as Slack, Microsoft Teams, Outlook, Gmail, Google Drive, and SharePoint and supercharge professionals’ AI agents with deeper context and know-how.’
Also, your Twin ‘learns the language, tone and communication patterns in your own private knowledge base and uses that context to draft responses in my style, including adapting how I communicate with different people. You remain in control and can review, edit or reject messages before they are shared.’
They continued that:
- There is an individual digital Twin for every person: which provides a continuously evolving model of each person’s knowledge, context, and judgment that can autonomously answer questions and act on their behalf.
- There is also an enterprise MCP server: which is a secure interface through which AI agents and enterprise tools can access governed context from an individual Twin or the wider Twin Network, and take action from that context.
- AI-mediated communications: Twins operate inside Slack, Microsoft Teams and email, using social and peer-to-peer context to support communication between humans to humans and humans to AI.
There is also a ton of privacy safeguards – as you’d expect.

One other aspect they highlighted is that the Twin approach provides ‘Sovereign AI: it gives enterprises control over their AI destiny by keeping their data, proprietary knowledge and governance policies under their control, while supporting flexible SaaS, single-tenant, and private-cloud deployment models and reducing dependence on any single model or infrastructure provider.’
Liu, co-founder and CEO of Twin1, commented: ‘In every knowledge organization, the human is the atomic unit of knowledge. The opportunity with AI is not to flatten people’s expertise into generic output, but to connect and amplify their unique knowledge, judgment and context.
‘Our belief is that AI should work for people, not be done to them. 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. We are building a future where expertise compounds, rather than collapses into the average.’
Wendy Butler Curtis, Chief Innovation Officer at Orrick, added: ‘Twin1 provides the opportunity to mine our collective data, and it is one of the most exciting developments in the practice today – because of the way it will enhance our client advice and make practicing more interesting.’
The other main investors were Tribeca Venture Partners and Aramco Ventures.
Is this a big deal?
Well, first it’s great to see Liu and team going back into legal tech after Eigen. Next, will Twin1 become a game-changer? Bagging $20m in Seed is certainly a sign of faith from investors.
But, how does it change things? For AL, the key aspect is that level of personalization. Harvey yesterday did a relaunch where the ability to curate and customise a lawyer’s preferences was absolutely central. To some degree this is similar, but perhaps with more of an emphasis on carrying around each lawyer’s knowledge base that is relevant to them, which they can then tap.
There are also connections in terms of ideas to what Eudia has been doing, where they’ve also been working on Expert Digital Twins, but in their case focused mostly on inhouse, and usually for the most experienced lawyers.
Moreover, as things evolve, once all that knowledge is no longer just in each lawyer’s head, it can then be tapped effectively across the firm. And that in turn connects to what Aloi in Sweden is doing around capturing and deploying firm-wide judgment.
In short, multiple legal AI companies are now moving in related orbits, with vectors aligned to context development, personalization, judgment gathering, and individual-to-organisation knowledge sharing.
