Duna's €30 Million Series A: When Stripe's Own Alumni Bet Big on Business Identity

The Stripe alumni network has produced some of the tech industry’s most ambitious founders. Now, a new company is proving that network’s reach extends into more corners of fintech than ever expected. Duna, a business identity verification startup, just closed a €30 million Series A round, making it the most heavily funded European company to emerge from what insiders call the “Stripe mafia”—the growing ecosystem of former Stripe employees launching ventures.

Founded by Duco Van Lanschot and David Schreiber, who both spent formative years at Stripe, Duna operates from headquarters split between Germany and the Netherlands. The company’s core mission is deceptively simple: make it easier for financial services firms to onboard business customers without the friction that typically comes with compliance checks and fraud prevention.

From Stripe’s Talent Pipeline to €30M Series A Raise

What makes Duna’s funding round remarkable isn’t just the size—it’s who’s backing it. CapitalG, Alphabet’s growth fund, led the Series A. This same investor co-led Stripe’s Series D back in 2016, creating a full-circle moment for the startup ecosystem. Beyond CapitalG, the company secured commitments from earlier backers Index Ventures (which led Duna’s €10.7 million seed round in May 2025) and Puzzle Ventures.

But the real signal of confidence comes from the angel investors and executives who participated. Michael Coogan, who served as Stripe’s COO, invested alongside David Singleton, the company’s former CTO, and Claire Hughes Johnson, a former COO. Even more striking: executives from Stripe’s fiercest competitor, Adyen, put money in—including Mariëtte Swart, Adyen’s Chief Risk and Compliance Officer, and CFO Ethan Tandowsky. Snowflake’s chairman Frank Slootman also participated, adding another layer of credibility.

This investor composition sends an unmistakable message: established players in payments and compliance see Duna as solving a real problem worth supporting, rather than a threat to be shut out.

Business Identity Verification: The Market Problem Duna Solves

The fintech industry has invested billions into streamlining consumer onboarding. But the business customer side remains clunky. Companies like Plaid already use Duna to accelerate their workflows, reducing the time and cost required to add corporate clients while cutting through the compliance maze that typically causes customer churn.

Duna competes in the Know Your Business (KYB) space, where it faces rivals like Jumio and Veriff. According to Alex Nichols, the CapitalG partner leading this investment, what separates Duna is its willingness to generate proprietary data rather than relying on aggregated third-party sources—which often have gaps and inaccuracies. Nichols frames this as a rare opportunity to rebuild foundational infrastructure, comparable to how Visa constructed its early network.

Why Industry Giants Won’t Build What Duna Does

One logical question emerges: Why aren’t Stripe and Adyen building this themselves? Van Lanschot argues the answer lies in complexity. Business onboarding requires extreme customization—every industry, every geography, every regulatory regime demands something slightly different. For a payment processor to offer this as a standalone product would require maintaining separate, customized solutions for each customer. That’s not a scalable business model.

Instead, Stripe and Adyen prefer to remain platform providers, which is precisely why they can comfortably invest in Duna. There’s no direct competition; it’s a complementary relationship.

Reusable Business Credentials: Duna’s Global Ambition

If Duna merely streamlined onboarding, it would be a successful point solution. But the company’s broader vision is more ambitious: building a shared digital identity layer for businesses. Van Lanschot envisions a world where corporate verification information gathered during onboarding with one service can be reused across others.

Think of it like a digital passport for businesses. A company that completes identity verification with Moss could reuse that credential to onboard more quickly with Plaid, or open a bank account without repeating the entire compliance process. This network effect compounds as more platforms join the infrastructure.

Finding Scale Through Interconnected Networks

Bringing that vision to life requires scale, but Duna isn’t waiting for global adoption. Instead, the company is targeting what Van Lanschot calls “patches of networks”—tightly interconnected communities of businesses where the verification benefits are immediate even without network-wide adoption. Think manufacturing clusters with shared customers, investment syndicates with overlapping limited partners, or businesses concentrated in small countries with aligned regulators.

The Netherlands offers a concrete example. The four largest Dutch banks employ 14,000 people in compliance roles, with roughly half dedicated to business customer review. While Duna won’t replace those jobs overnight, AI-driven automation can already reduce compliance costs and unlock new revenue streams. That’s compelling value even before the full network reaches critical mass.

The Emerging Competitive Edge

Duna’s success reflects a broader pattern: the best venture-backed companies often emerge from the intersection of insider knowledge and outside thinking. Van Lanschot and Schreiber understood Stripe’s limits and opportunities because they had worked within the system. That perspective—combined with the support of executives from Stripe and Adyen—suggests this company is building something both founders and investors believe will reshape business onboarding at scale.

If Duna succeeds, the endgame is elegantly simple: one-click onboarding for business accounts, similar to how Stripe Link simplified B2B payments or Amazon perfected consumer checkout. Once more, the influence of Stripe’s alumni continues to shape the future of fintech.
