Duna raises €30 million to build global business identity network

Duna, a business identity verification startup based in Germany and the Netherlands, has raised a €30 million Series A funding round. The investment was led by CapitalG, Alphabet’s growth fund. This funding positions Duna as the best-funded European member of the Stripe mafia—a term used to describe the network of former Stripe employees who have gone on to found technology startups. Duna was co-founded by Stripe alumni Duco van Lanschot and David Schreiber. While Stripe itself is not a customer of Duna, several of its executives, alongside executives from rival fintech firm Adyen, have backed the company as angel investors.

The startup’s core ambition is to build a global trust infrastructure for business identity, addressing the category known as KYB, or Know Your Business. Duna aims to create a reusable digital passport for companies, allowing them to share verified identity files across different platforms to streamline onboarding. Co-founder Duco van Lanschot explained the long-term vision: “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”

This approach differentiates Duna from existing KYB vendors such as Jumio and Veriff. According to Alex Nichols, a general partner at CapitalG who led the investment, Duna stands out because of its decision to generate its own data rather than aggregating incomplete external sources. Furthermore, major payment processors like Stripe or Adyen are unlikely to spin out their own onboarding systems as standalone products due to the highly customized, company-by-company controls required. The scale of the compliance challenge is significant; van Lanschot noted that the four largest banks in the Netherlands employ 14,000 people in compliance, with half focused on businesses. CapitalG later clarified that there are 13,000 compliance employees across all Dutch banks.

To scale before achieving full network effects, Duna is targeting patches of networks—small, overlapping clusters of businesses such as investment firms with shared limited partners (LPs). The company’s long-term strategy includes the potential to enable one-click business onboarding, though the source notes there might be an even bigger opportunity in taking advantage of this position.

The Series A round saw participation from several investors:

• Index Ventures, which previously led Duna’s €10.7 million seed round in May 2025
• Puzzle Ventures
• Frank Slootman, the chairman of Snowflake

Why it matters

Duna is attempting to solve the fragmented, manual nature of business identity verification by building a reusable digital passport for companies, potentially creating a new foundational layer for B2B commerce.
