Company Description

BlaBlaCar’s vision is to bring fairness, freedom and fraternity to the world of travel. 

BlaBlaCar was created in 2006 with one dream in mind: fill the millions of empty seats on the road to create an efficient, affordable and friendly way to travel. Today, our global, trusted community counts 85 million members in 22 countries, enabling a smarter, large scale and truly sustainable transport network. 

Born from a simple idea of people sharing their rides, BlaBlaCar’s ambition is to become the go-to marketplace for shared road mobility. We offer long distance carpooling service, a commuting carpooling service, and since 2018  a marketplace bus service too. A filled bus emits one third of the emissions per passenger kilometer as an average car. So we want to fill those seats too!
