Paazl is now Wuunder

The history of Paazl

Paazl was founded in 2009 in Amsterdam by Bernard Schreiner and Ramon Keijsers. The two were neighbours, and the idea was born from personal frustration: parcels that never arrived when you were home. Their solution: a SaaS checkout widget that let consumers choose where, when and how their order was delivered.

The name Paazl was born when the founders noticed an early team member with a thick New Zealand accent always pronounced "parcel" differently: it sounded like "pahsil". That play on pronunciation became the company name.

Paazl grew into an established delivery management solution for mid-size and large e-commerce brands with a D2C focus.  Bernard Schreiner departed in January 2021 after 12 years. 

In June 2023 the acquisition by Wuunder was announced. Ramon Keijsers: "Together we are at the foundation of becoming a European industry leader, by combining end-to-end transport solutions with the best e-commerce delivery experience." 

Ramon Keijsers left Wuunder in February 2024 with the integration well underway: "Having combined powers with Wuunder, the future of Paazl has never looked brighter." 

The Paazl checkout technology lives on as Wuunder Checkout. The combined platform now offers Paazl's checkout expertise together with Wuunder's logistics depth.
