Duna, an identity fintech founded by two Stripe alumni, has raised a €30 million Series A to expand its AI native business identity platform for regulated enterprises. The round was led by CapitalG, Alphabet’s independent growth fund, with participation from existing investors Index Ventures and Puzzle Ventures, as well as Snowflake Chairman Frank Slootman.
Based in Germany and the Netherlands, Duna was launched in 2023 by Duco van Lanschot and David Schreiber, both former Stripe leaders. The company previously announced a €10.7 million seed round led by Index Ventures in May 2025. With the new financing, Duna said its total funding now exceeds €40 million.
Duna is positioning itself as a global trust infrastructure that provides a digital passport for every business, aiming over time to evolve into a shareable identity network that supports one-click onboarding. Today, the company sells to large banks, fintechs, platforms, and financial institutions, and says customers include Plaid, CCV (Fiserv), Moss, Bol, and SVEA bank. Duna reports customer outcomes that include 10.6x faster onboarding and 4.8x productivity gains.
The company plans to use the new capital to expand enterprise capabilities, with a focus on compliant, auditable AI while maintaining regulatory standards required by banks and large enterprises.
KEY QUOTES
“Duna is addressing one of the internet’s biggest unsolved problems: identity. Compliance and identity now consume up to 10-20 percent of a bank’s total costs. The expensive and manual legacy systems lead to billions lost in fraud, friction, and fines, as well as lost income from refusals of legitimate customers. This makes it an ideal use case for AI automation.”
“We have seen strong traction with leading enterprise customers. The funding will be used to further expand our enterprise capabilities with compliant, auditable AI, while maintaining the high regulatory standards required by banks and large enterprises.”
Duco van Lanschot, Founder, Duna
“The need for a secure business identity has never been more urgent: AI has many benefits, but it also enables an acceleration in the velocity and sophistication of fraud. Duna will help companies root out this fraud. We are turning a decades-old compliance cost center into a core revenue driver.”
David Schreiber, Founder, Duna
“Duna is building the internet’s missing ‘one click’ identity network. Most new business relationships start with a painful, manual, and time-consuming exchange of documents which amount to a massive hidden tax on the B2B economy. Duco and David are the perfect founders to solve business identity for the internet. As former leaders at Stripe, they possess not only deep founder-market fit but also the leadership skills to build a high-ownership, talent-dense culture to achieve such an ambitious vision.”
