BlaBlaCar is the world's largest long-distance ridesharing community. Conceived in December 2003 by Frédéric Mazzella, and founded in 2006, BlaBlaCar connects drivers and passengers willing to travel together between cities and share the cost of the journey. BlaBlaCar has more than 25 million members across 22 countries.
Members must register and create a personal online profile, which includes ratings and reviews by other members, social network verification, and rate of response. “Profiles of members show how much experience they have of the service, meaning those with more – known as "ambassadors" – attract more ride shares and, importantly, each user's profile includes a "BlaBla" measurement, which indicates how much they are willing to chat during a trip”.
As of April 2015, the company had raised USD$100 million from blue-chip venture-capital firms including ISAI, Index and Accel, plus earlier rounds of €1.2 million from ISAI and €600,000 from founders, friends, and family.
On September 16 2015, BlaBlaCar announced it had raised another US $200 million "primarily from US investors" in a round that valued the company at USD$1.6 billion.
The service is accessible via the web, mobile and also via apps for iOS and Android.
