As the FT reported, the pop turned into a jump, then it started to look like an explosion as . Adyen's first day on public markets in Amsterdam saw its valuation rise to more than €13bn - more than established European financial groups like Commerzbank!
Adyen won a contract with eBay this year, ending a 15-year partnership between the ecommerce marketplace and PayPal. Its Amsterdam IPO comes less than a month after the US payments giant swooped in to buy Swedish payments start-up iZettle just before it was set to list in Stockholm. Adyen was founded 12 years ago and acts as a middleman between merchants and other payment companies, negotiating deals with the likes of Visa and Mastercard in the US and UK, Cartes Bancaires in France, Oxxo in Mexico and Alipay and UnionPay in China.
