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 Central Teams based in our main Hub in Barcelona and our other global Hubs in Amsterdam, Paris and Berlin. Our local brands are founded on the connections between people, and as an international group we create networks of talented Adevintans who work together towards a common purpose across geographies and disciplines.
