Duna, Founded by Stripe Alumni, Secures €30M Series A

Duna, a fintech startup co-founded by former Stripe executives, has successfully closed a €30 million Series A funding round led by Alphabet's growth fund, CapitalG. This significant investment positions Duna as one of Europe's best-capitalized startups founded by Stripe alumni, aiming to transform business identity verification and enterprise onboarding processes.

Stripe has become renowned as a "founder factory," with numerous former employees launching successful ventures. Duna is the latest example of this trend, now a prominent member of the so-called "Stripe mafia." CapitalG, which also co-led Stripe's Series D in 2016, demonstrates continued confidence in ventures stemming from the payment giant's talent pool.

Revolutionizing Business Onboarding

Based in Germany and the Netherlands, Duna was co-founded by Stripe alumni Duco Van Lanschot and David Schreiber. The startup specializes in helping fintech companies, including clients like Plaid, to onboard business customers more efficiently. By streamlining corporate ID checks and other fraud prevention measures, Duna significantly reduces the typical churn associated with these processes.

While Stripe is not a Duna customer, the startup has garnered strong endorsement from key figures within the fintech ecosystem. Its angel investors include current Stripe COO Michael Coogan and former executives David Singleton (CTO) and Claire Hughes Johnson (COO). Even Stripe's competitor, Adyen, has shown support, with CRCO Mariëtte Swart and CFO Ethan Tandowsky joining as angel investors.

"It requires such fine-grained controls that change 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 change all of the configurations," Van Lanschot told TechCrunch, explaining why these giants would not compete directly with Duna.

Duna primarily targets the "long tail" of enterprise clients that may lack extensive resources for business onboarding. However, its ambition extends beyond this. Duna envisions building a global trust infrastructure where businesses can reuse 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 reuse your file from onboarding on [German spend management platform] Moss to onboard with Plaid, or you can reuse it to open up a bank account," Van Lanschot explained.

Investor Confidence and Market Differentiation

Alex Nichols, the General Partner at CapitalG who led the Series A investment, highlighted the appeal of Duna's vision.

"I would say the common thing I look for in my investments are some sort of network effects, or more formal scale advantage," Nichols shared with 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."

In the competitive Know Your Business (KYB) category, Duna faces rivals such as Jumio and Veriff. However, Nichols believes Duna's unique approach of generating its own data, rather than merely aggregating often-incomplete existing sources, sets it apart. He described it as "the rare opportunity to rebuild something as foundational as a Visa and create an amazing business in the process."

Scaling Strategy and Future Vision

Duna has already demonstrated a strong business case by helping customers achieve faster and more cost-effective corporate user onboarding. This success has prompted existing investors, including Index Ventures (which led Duna's €10.7 million seed round in May 2025), Puzzle Ventures, and Snowflake chairman Frank Slootman, to participate in the Series A.

To achieve its broader network ambitions, Duna is employing a strategic scaling approach. Van Lanschot and his team are identifying "patches of networks" – small clusters of companies with existing overlaps, such as manufacturing firms with shared customers, investment firms with overlapping LPs, or businesses within the same small country. This allows the immediate value of reusable verification to be realized even before full network effects are achieved.

The market opportunity for Duna is substantial. Van Lanschot pointed to the Netherlands, a relatively small country, where the four largest banks employ 14,000 people in compliance, with half dedicated to business-related tasks. While Duna may not fully replace these roles yet, AI automation offers significant cost savings and revenue generation, even in the early stages.

Ultimately, if Duna establishes itself as the infrastructure for a global identity network, an even larger opportunity lies in enabling one-click business onboarding. This would parallel the convenience of Amazon's one-click checkout or, in the B2B context, Stripe Link, once again highlighting the enduring connection to its Stripe-rooted origins.
