Public Transport Authorities

Away from city centres, the production cost of a Karos trip is 10x cheaper than bus or metro. PTAs use Karos to reduce their carbon footprint, fight congestion and extend the reach of their public transportation networks.

Mobility Operators

With Karos, PTOs can complement their mobility offering with a low cost and carbon efficient mode of transportation, to better serve their PTA clients needs . As 75% of Europeans commute by car, carpooling is a great way to target more and new users.

Service Providers

We collaborate with Mobility Service Providers, to expand the green mobility offering and better serve our respective PTO and PTA partners.

Karos’ first steps abroad

Karos develops, deploys and maintains the software and support local partners with best practices and carpool knowledge to ensure the success of the deployment in the country.


We work closely with our local partners to transform empty car seats into organized transport networks for passengers willing to commute each day in an efficient way.

The Federation of Danish motorists is an association that provides services (insurance, assistance, hotlines…) to car owners in Denmark. FDM wanted to bring a carbon efficient mobility solution for their members.

From 2021, they operate the Karos platform in Denmark, working with both big corporations and local communities.
