Karos is a daily carpooling operator aiming at helping territories and employers building their own local everyday carpooling service.
Technology & Innovation
Our matchmaking algorithms predict mobility needs and enhances themselves by reviewing carpool trips and proposing the best itineraries to drivers and passengers.
Complementarity between stakeholders
We actively work with territories, companies and government to fully connect the territory. Thanks to user communities created in our partner companies, cars are an active part of public transport and connect territories.
Adapting to the local context
Our operator role isn't only just providing a carpooling solution. Our teams strive to help carpooling grow and connect territories by helping them to fully integrate the service within their mobility offer.
