Twin1 AI provides professionals with AI-powered digital twins grounded, with permission, in their emails, meetings, documents and workplace systems. The company states that each twin reflects a person's knowledge, judgment, relationships and working context, with the aim of helping organizations preserve and securely share institutional expertise while maintaining privacy, permissions and human control. According to the company, the platform operates across email, meetings, documents, Slack and Microsoft Teams, and works with clients across legal, financial services and energy, including Linklaters, Orrick, Dechert and Aegis Energy. Twin1 AI was founded in 2025 and has teams in San Mateo, its headquarters, and London.
The new capital will be used to expand deployments across credit unions, global law firms and major financial institutions, scale the San Mateo and London teams, build out the enterprise go-to-market organization, and accelerate development of the Twin Network, autonomous capabilities and governance controls required by regulated enterprises. Dr. Lewis Z. Liu, co-founder and CEO of Twin1 AI, said Curql's investment would help bring the capability to more credit unions while accelerating growth in other core verticals. He cited the company's work with Shoreline Credit Union.
Nick Evens, President and CEO of Curql, said credit unions need a secure, governed way to capture employee expertise. Nathan Grossenbach, President and CEO of Shoreline Credit Union, said Twin1 helps make institutional knowledge accessible across the credit union rather than leaving it in emails, chats and documents or concentrated among a few key people. Curql describes itself as a fintech investment ecosystem built by and for credit unions; its Curql Fund II closed in 2025 at $360 million, the largest credit union-led fintech fund, following Fund I's $252 million close in 2021.
