Twin1 AI, a privacy-focused AI startup developing digital twins for professionals, has raised an additional $5 million in seed funding in a round led by Curql, a strategic investment fund backed by more than 160 credit unions.
The round also included participation from Greyhair Ventures, KittyHawk Frontier, and several angel investors, including Apex Star Capital, Xiaomi co-founder Bin Lin’s family office, early Google engineer Fan Li, McKinsey Senior Partner Raj Bector, Isaac Levy, and former McKinsey Senior Partner Cindy Levy.
The latest investment brings Twin1 AI’s total seed funding to $25 million. It follows the company’s $20 million seed round announced in August 2026, which was co-led by Bessemer Venture Partners, Tribeca Venture Partners, and Aramco Ventures.
Twin1 AI will use the new funding to expand its deployments across credit unions, global law firms, and major financial institutions. The company also plans to grow its teams in San Mateo and London, strengthen its enterprise sales operations, and accelerate development of its Twin Network, autonomous AI capabilities and governance tools.
“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.”
Twin1 AI, which originated in 2025, creates AI-enabled digital duplicates. They are accurate representations of specific humans. They learn about their owners’ work habits through emails, meetings, documents, and systems.
These duplicates have been created to help understand a person’s expertise and their style of communication, their contacts, and their work environment. They will allow users to automate communication processes while keeping the company secrets safe.
The platform integrates with various office tools like email, Slack, Microsoft Teams, meetings, and document systems. The platform also enables the functioning of digital twins through a secured network, enabling organizations to link information to numerous teams and units within their organization.
“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.”
Twin1 AI focuses on businesses where the issues of information confidentiality and security are very highly regarded, for example the legal services sector, the financial services sector, and the field of energy. The company’s clients are Linklaters, Orrick, Dechert, and Aegis Energy.
The company is also working with Shoreline Credit Union, where its digital twin technology helps employees access organizational knowledge while meeting the privacy and governance requirements of financial institutions.
With the latest funding, Twin1 AI aims to expand its enterprise presence and develop more advanced digital twin capabilities for businesses looking to automate communication and improve knowledge sharing.
