Twin1 AI, the privacy-first platform that gives every professional an AI-powered digital twin to automate communication, today announced a $5 million extension to its seed financing. The extension is led by Curql (a strategic investment fund backed by more than 160 credit unions), with participation from Greyhair Ventures and KittyHawk Frontier, as well as angel investors including Apex Star Capital, the family office of Xiaomi co-founder Bin Lin, early Google engineer Fan Li, McKinsey Senior Partner Raj Bector, family office investor Isaac Levy, and former McKinsey Senior Partner Cindy Levy.

The extension brings Twin1 AI’s Series Seed financing to $25 million. It follows the company’s August 2026 announcement of its $20 million seed round, co-led by Bessemer Venture Partners, Tribeca Venture Partners and Aramco Ventures, and its launch from stealth.

Twin1 AI will use the new capital to expand deployments across credit unions, global law firms and major financial institutions, while continuing to grow in the broader enterprise space. The company will also scale its San Mateo and London teams, build out its enterprise go-to-market organization, and accelerate development of the Twin Network, autonomous capabilities and governance controls required by regulated enterprises.

Twin1 AI pairs professionals with AI-powered digital twins grounded, with permission, in their emails, meetings, documents and workplace systems. Each Twin reflects the person’s knowledge, judgment, relationships and working context, helping organizations preserve and securely share institutional expertise while keeping privacy, permissions and human control at the core.

“Credit unions are built on trusted relationships, local knowledge and a deep commitment to their members,” said Dr. Lewis Z. Liu, co-founder and CEO of Twin1 AI. “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.”

“Every credit union has people whose knowledge holds the organization together, and too often that knowledge leaves when they do,” said Nick Evens, President and CEO of Curql. “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 investment builds on Twin1 AI’s work with Shoreline Credit Union and other clients, where digital twins help employees access organizational knowledge and expertise within the privacy and governance requirements of a regulated financial institution.

“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,” said Nathan Grossenbach, President and CEO of Shoreline Credit Union. “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.”
