Adriaan Mol — The decisions behind Mollie

From SMS services to a European payments platform. Which choices made the difference?

Adriaan Mol founded Mollie in 2004, when he was eighteen. The company started out with SMS and telecom services and added payments in 2006. For fifteen years it grew without outside investors. Then came funding rounds worth hundreds of millions, changes at the top and, in 2026, the completion of the acquisition of the British company GoCardless.

But behind that success lies a far more complicated story.

In this independent FOREFACT publication you discover how an internal payments problem grew into the core product, why Mollie bet on simplicity for developers and pricing without contracts, and why bootstrapping at some point no longer seemed enough. It doesn’t only cover the successes. It also covers the high costs and the reorganisation after the record funding round of 2021, the operating loss for 2025, the competition with Adyen and Stripe and an analyst’s critical questions about the GoCardless acquisition.

From story to practice

This is more than a founder biography. As you read, you are challenged to make decisions yourself. In six in-depth Decision Labs you learn, among other things, how to calculate the margin per transaction, run the numbers on a pricing model without contracts, work out dilution and runway, and critically test an acquisition paid in shares.

What do you get?

• 44 pages with the full founder story.

• Eight chronological chapters on how Mollie developed.

• Six Decision Labs with business theory and fictional worked examples.

• Twelve digitally fillable worksheet pages with 24 fields in total and answer checks.

• A six-week Reality Test to apply the lessons yourself.

• A historical timeline and a box on what’s different in the Netherlands.

• 36 source references for further reading and verification.

Who is this guide for?

For curious readers, (aspiring) entrepreneurs and anyone who wants to understand how a Dutch tech company grew into a European payments player. Also of interest if you want to know more about payments, pricing strategy, investors, the cost of growth and acquisitions.

You don’t just read how Mollie grew. You examine which decisions, risks and lessons you can apply yourself.
