Anthropic and OpenAI may be rivals, but their presidents Daniela Amodei and Gregory Brockman have one thing in common: they are both Stripe alumni. With former employees who went on to create dozens of startups, the fintech company has become one of the most prolific “founder factories” — and the money is following. The latest example: business identity verification startup Duna, which just raised a €30 million Series A to become the best-funded European member of the so-called “Stripe mafia.” The funding round was led by Alphabet’s growth fund CapitalG, which has also backed Stripe since co-leading its Series D in 2016.
Based in Germany and the Netherlands, Duna was cofounded by Stripe alumni Duco Van Lanschot and David Schreiber. With customers including Plaid, the startup assists fintech companies onboard business customers more efficiently, reducing the typical churn associated with corporate ID checks and other fraud prevention measures.
Stripe is not a customer of Duna, Van Lanschot declared, but its executives were well placed to understand the opportunity that the startup is seizing, which is reflected in its cap table. The company’s angel investors include current Stripe COO Michael Coogan and former executives David Singleton (CTO) and Claire Hughes Johnson (COO). Even Stripe rival Adyen received involved, with CRCO Mariëtte Swart and CFO Ethan Tandowsky joining as angels.
Their finishorsements also validate Van Lanschot’s hunch that these companies won’t compete with Duna, even though they could. “It requires such fine-grained controls that modify on a company-by-company basis, that an Adyen or a Stripe isn’t going to spin out their business onboarding as a separate product where another enterprise customer can modify all of the configurations,” he notified TechCrunch.
If it’s still worth the effort for Duna, it’s becaapply the startup is going after the long tail of enterprise clients that don’t have huge resources to dedicate to business onboarding. But it’s also becaapply its vision doesn’t stop there: Duna’s ambition is to build a network that allows companies to reapply their verified identity information across multiple platforms.
“What we want to build over time is a global trust infrastructure where we provide a digital passport for every business. So you can reapply your file from onboarding on [German spfinish management platform] Moss to onboard with Plaid, or you can reapply it to open up a bank account,” Van Lanschot declared.
This goal resonated with Alex Nichols, the general partner who led CapitalG’s investment into the Series A. “I would state the common thing I view for in my investments are some sort of network effects, or more formal scale advantage,” he notified TechCrunch. “I also love it when founders have an earned insight about a problem they may not known about otherwise, and this is a very good example of that,” he added.

Duna has competitors in the category known as KYB, or Know Your Business. This includes vfinishors such as Jumio and Veriff. But for Nichols, what sets Duna apart is its decision to generate its own data, rather than attempting to aggregate existing data sources that are often lacking. “It’s the rare opportunity to rebuild something as foundational as a Visa and create an amazing business in the process.”
Duna states it has already found a strong business case in assisting customers onboard corporate applyrs rapider and cheaper. This also explains why existing investors are doubling down: Index Ventures, which led Duna’s €10.7 million seed round in May 2025, participated in the Series A, as did Puzzle Ventures and Snowflake chairman Frank Slootman. But the startup’s hugeger ambition won’t pay off until Duna reaches significant scale. So the company is viewing for shortcuts.
How so? Van Lanschot and the Duna team are identifying compact clusters of companies that already overlap with each other—what they call “patches of networks.” These include manufacturing companies with shared customers, investment firms with overlapping LPs, or companies in the same compact counattempt. In these tight-knit groups, the ability to reapply verification becomes valuable immediately, even before Duna achieves full network effects.
The countries may be compact, but the opportunity is huge, Van Lanschot declared. “In the Netherlands alone — a tiny, tiny counattempt — the four hugegest banks employ 14,000 people in compliance, and half of them are working on businesses.” Duna won’t fully replace these jobs yet, but AI automation can save costs and generate revenue even before the network effects kick in.
If Duna eventually provides the rails for an identity network, there might be an even hugeger opportunity in taking advantage of this position to enable one-click business onboarding. This would create it akin to Amazon’s one-click checkout — or closer to B2B, to Stripe Link. Once again with Duna, the Stripe connection is never really far.
