MOLLIE

Adriaan Mol founded Mollie in 2004 during the earliest days of European e-commerce. He saw that small Dutch online shops had no good way to accept payments without dealing with bank bureaucracy.

He built a simple API and made it easy. The company grew slowly and deliberately for over a decade before the e-commerce boom made it rocket.

They bootstrapped for years before taking outside funding.

Transaction-fee based. Mollie charges merchants a percentage plus a flat fee per transaction, varying by payment method — iDEAL, credit card, SEPA, PayPal, and many others.

No monthly fees, no setup costs for smaller merchants. They also offer a Mollie Capital product providing revenue-based financing to their merchant base.

[ "Mollie Payments — accept 30+ payment methods across Europe via a single API integration", "Mollie Capital — revenue-based financing for merchants, funded against their Mollie transaction history", "Mollie Embed — white-label payment infrastructure for platforms and marketplaces" ]

SMB-first in the Netherlands, then expansion across Europe. They built local payment method support for every major European market — iDEAL in the Netherlands, Bancontact in Belgium, Sofort in Germany.

This localization is their biggest moat. Stripe and Adyen compete at the enterprise end.

Mollie owns the European small business segment.

Competing against Stripe (which has moved aggressively into Europe) and local banks offering payment solutions to their own business customers. Mollie must keep the product simple as they add financial services complexity — Mollie Capital, embedding, and platform payments all risk bloating what made them great.

Backed by Blackstone, TCV, General Atlantic, EQT Ventures, HMI Capital, and Sofina. The 2021 Series C was one of the largest fintech rounds in European history at the time.
