Twin1 AI Raises $5 Million Seed Extension, Hits $25 Million Total

Twin1 AI has closed a $5 million seed extension led by Curql, pushing the startup's total seed financing to $25 million as it pushes AI-powered digital twins into financial services, legal organizations and other regulated enterprises.

Greyhair Ventures and KittyHawk Frontier joined the round, along with Apex Star Capital and individual investors Fan Li, Raj Bector, Isaac Levy and Cindy Levy. The extension builds on a $20 million seed round announced in August 2026, co-led by Bessemer Venture Partners, Tribeca Venture Partners and Aramco Ventures.

What does Twin1 actually build?

The San Mateo- and London-based company, founded in 2025, builds digital twins grounded — with permission — in professionals' emails, meetings, documents and workplace systems. The software runs across tools including email, Slack and Microsoft Teams, and it's designed to mirror individual knowledge and working context while making organizational expertise searchable and shareable.

Individual twins connect through what the company calls a Twin Network, a permission-aware layer that lets expertise move across an organization without breaking access rules. The pitch directly targets a pain point every practitioner knows: institutional knowledge concentrated in a few people's heads, or scattered across systems, walks out the door when those people leave.

Twin1 already works with Linklaters, Orrick, Dechert and Aegis Energy, alongside its flagship credit union deployment at Shoreline Credit Union, where employees use the technology to surface information otherwise trapped in communications, documents and individual experts.

Why Curql's backing matters

Curql is backed by more than 160 credit unions, which makes its lead investment a distribution signal as much as a capital event. For Twin1, one strategic investor now opens a channel into a sector that buys carefully and governs tightly.

Dr. Lewis Z. Liu, co-founder and CEO of Twin1 AI, framed the deal around that exact wedge: "Credit unions are built on trusted relationships, local knowledge and a deep commitment to their members. Our work with credit unions such as Shoreline has shown how AI-powered digital twins can preserve that knowledge and make it available across an organization without compromising privacy or human agency. Curql's strategic investment will help us bring this capability to more credit unions while accelerating growth across our other core verticals."

Nick Evens, president and CEO of Curql, put the problem in starker operational terms: "Every credit union has people whose knowledge holds the organization together, and too often that knowledge leaves when they do. Twin1 gives credit unions a secure, governed way to capture that expertise and put it in the hands of every employee serving members. It's exactly the kind of practical AI credit unions need right now."

The customer view tracks with the investor thesis. Nathan Grossenbach, president and CEO of Shoreline Credit Union, said: "Twin1 is helping make Shoreline's institutional knowledge accessible across the credit union, instead of leaving valuable information buried in emails, chats, documents, or concentrated in a few key people. Twin1 gives us a secure way to make that expertise more accessible, helping our team find trusted answers faster and spend more time serving our members."

What does this change for buyers in regulated sectors?

The money has a specific job list. Twin1 will fund expanded deployments across credit unions, global law firms and financial institutions; grow its San Mateo and London teams; build out its enterprise commercial organization; and develop the Twin Network, autonomous capabilities and governance controls.

That last item is the real tell. Twin1 is betting that in regulated environments, privacy, permissions and human control aren't compliance checkboxes — they're the product. Every dollar going into governance tooling is a dollar aimed at buyers who've stalled on AI rollouts over exactly those concerns.

For legal and financial decision-makers, the signal is that permission-aware AI is now being underwritten by the institutions themselves: a fund owned by 160-plus credit unions just put capital behind a vendor whose first reference customer can speak to governed knowledge retrieval in production. Expect the credit union vertical to scale first, with law firms — where Linklaters, Orrick and Dechert are already in the door — as the next proving ground.
