Duna Raises €30M Series A from Stripe Alumni and Industry Giants

The startup world has long recognized that Stripe operates as a talent incubator for future founders. From Anthropic’s Daniela Amodei and OpenAI’s Gregory Brockman to countless others, the company’s alumni network continues producing successful ventures. The latest and most remarkable case is Duna, a business identity verification startup that just closed a €30 million Series A funding round. This positions Duna as the most well-capitalized European company to emerge from the so-called “Stripe mafia”—the informal network of former Stripe employees turned entrepreneurs.

The funding round was led by CapitalG, Alphabet’s growth investment arm, which has backed Stripe since co-leading its Series D in 2016. Beyond traditional venture investors, Duna secured backing from prominent angels and institutional supporters, including Michael Coogan (Stripe’s Chief Operating Officer), David Singleton (former CTO), and Claire Hughes Johnson (former COO). Even competitors like Adyen contributed to the round through executives Mariëtte Swart (Chief Revenue and Commercial Officer) and Ethan Tandowsky (Chief Financial Officer). This broad-based support reflects genuine confidence in Duna’s approach to an underserved market.

The Problem Duna Solves: Enterprise Onboarding at Scale

Headquartered across Germany and the Netherlands, Duna was founded by Duco Van Lanschot and David Schreiber, both veterans of Stripe’s payments platform. The company tackles a critical pain point in fintech: helping enterprises rapidly onboard business customers while reducing fraud risk and compliance friction. Clients like Plaid rely on Duna to streamline these verification processes, cutting both the time and cost of corporate customer acquisition.

The business identity verification market—often called KYB (Know Your Business)—has grown as fintech platforms expanded. However, the existing solutions, provided by competitors like Jumio and Veriff, typically rely on aggregated third-party data that can be incomplete or outdated. Duna differentiates by generating its own proprietary data through direct verification channels, creating a more reliable foundation for business identity checks.

Why Stripe and Adyen Won’t Compete with Duna

One might expect Stripe or Adyen to launch competing products internally. However, Van Lanschot argues this won’t happen—and the large platforms appear to agree, given their public backing of Duna. The reason is structural: business onboarding requires such extensive customization for each enterprise client that it doesn’t make economic sense for payment giants to offer KYB as a generic product to competitors. Building and maintaining such a system would dilute focus from their core payments business while generating limited revenue.

By investing in Duna instead, Stripe and Adyen gain access to best-in-class verification infrastructure without the operational burden. This strategic partnership model reflects how mature platforms increasingly prefer to back innovative specialists rather than expand vertically into adjacent markets.

Duna’s Bigger Vision: The Business Digital Passport

Beyond solving today’s onboarding challenges, Duna’s founders envision a more ambitious future: a global network where verified business identities become reusable across multiple platforms. Imagine a “digital passport” for enterprises—where identity verification performed during onboarding with one service (like Moss) could be instantly reused when opening accounts with another (like Plaid) or establishing banking relationships.

This network-effect play resonates with Alex Nichols, the CapitalG partner who led Duna’s Series A. Nichols specifically targets investments where network effects create compounding value or where founders have genuine insights into problems that larger incumbents haven’t recognized. Duna fits both criteria: as more enterprises and platforms join its network, the verification process becomes faster and cheaper for all participants—a virtuous cycle.

From Local Networks to Global Scale

Duna’s path to realizing this vision involves a deliberate strategy: targeting what Van Lanschot calls “patches of networks”—tight-knit clusters of interconnected companies. These might include manufacturers sharing customers, investment consortiums with overlapping limited partners, or businesses within a single country’s economy. Within these close-knit groups, the benefits of reusable verification accumulate quickly, even before Duna achieves the scale needed for true network effects.

The Netherlands provides a compelling test case. The country’s four largest banks employ approximately 14,000 people dedicated to compliance, with roughly half focused on business customer onboarding and fraud prevention. While Duna won’t eliminate these roles overnight, AI-driven automation powered by its verification infrastructure can meaningfully reduce costs and enhance revenue per compliance officer. This represents immediate value before the full potential of a global network unlocks.

What’s Next for Duna

The Series A funding reflects confidence from major investors and industry participants. Index Ventures, which led Duna’s €10.7 million seed round in May 2025, participated again alongside Puzzle Ventures and Snowflake chairman Frank Slootman. With this capital, Duna can accelerate its playbook across new markets and deepen its technology.

If Duna successfully establishes itself as the infrastructure layer for business identity verification, the long-term opportunity becomes transformative. One-click onboarding for enterprises—similar to Amazon’s one-click checkout or Stripe Link’s simplicity for B2B transactions—would represent a fundamental shift in how businesses interact with financial services. Once again, Stripe’s ecosystem has proven its ability to incubate companies that redefine category standards.
