Mollie

Mollie processes €100 billion in annual transaction volume, which at estimated 0.8% average take rate implies roughly €800 million in revenue. That revenue number puts the company at roughly 8x revenue multiple — reasonable for a profitable payments business with demonstrated European merchant density. The strategic problem is that Mollie won market share by being easier and cheaper than Stripe for small European merchants, and that advantage erodes as Stripe localizes and as Adyen expands downmarket. Mollie's customer base skews heavily toward SMBs in Netherlands and Belgium, which means growth requires either moving upmarket into enterprise accounts where Adyen dominates or expanding into new geographies where Stripe's brand and API familiarity create immediate headwinds. The company raised €800 million in 2021 at peak European fintech enthusiasm and has been quiet since — which usually signals either comfortable profitability or difficult growth conversations.

VERDICT: DANGEROUS — Mollie built the best European alternative to Stripe for small merchants, then watched Stripe acquire those same local payment rails for €200 million and Adyen launch point-of-sale terminals that turn payment processing into physical infrastructure European SMBs cannot easily switch away from
