Company Description

We’re Adevinta, a global leader in digital marketplaces. Our household name brands, including marktplaats in the Netherlands, Mobile.de in Germany and leboncoin in France, reach hundreds of millions of people every month across 16 countries. 

We’re all about matchmaking, and our sites help people find whatever they’re looking for in their local communities – whether it’s a car, an apartment, a sofa or a new job. Every connection made or item found makes a difference by creating a world where people share more and waste less. 

Our brands are supported by global Tech Hubs in Barcelona, Amsterdam, Paris and Berlin. Their goal is to develop common global products and innovation platforms which all of our brands can use. This means using cutting edge technology to create highly scalable, customisable and secure products and components that free up development time and leverage our access to global data.
