Based in Germany and the Netherlands, Duna was co-founded by Stripe alumni Duco van Lanschot and David Schreiber. Stripe is not a customer of Duna, van Lanschot said, 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 former Stripe executives David Singleton (CTO), Claire Hughes Johnson (COO) and Michael Cocoman (Global Chief Compliance Officer). Even Stripe rival Adyen got involved, with CRCO Mariëtte Swart and CFO Ethan Tandowsky joining as angels. The countries may be small, but the opportunity is big, van Lanschot said.
