Company Description

BlaBlaCar's vision is to bring fairness, freedom & 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 & friendly way to travel. Today, our global, trusted community counts 75 million members in 22 countries, enabling a smarter, large scale & 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, & 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!

In 2018, 84 million travellers used BlaBlaCar globally saving 1.6 million tons of CO2. Meanwhile we enabled human connections, bringing people closer together in more ways than one with 87% of members say that carpooling is an enriching experience.

BlaBlaCar offers a truly & unique international environment with a team counting 35 nationalities, serving a global member-base from 8 offices in Berlin, Kiev, Madrid, Milan, Moscow, Paris (HQ), So Paulo, Warsaw. English is the official spoken language across BlaBlaCar. We are privately-held & founder-led. Our team of 500 employees is entrepreneurial, passionate, & fundamentally mission-driven.
