Frequently asked questions

Karos enables public authorities and employers to structure daily carpooling as a reliable mobility solution, fully complementary to public transport and designed to operate at territorial scale.
How do I get started with Karos?

Getting started is simple: download the app, create your profile and enter your usual route. Karos will then suggest matches with other commuters travelling the same way, so you can start sharing rides right away.

Is Karos suitable for my daily home-to-work commute?

Karos is built for regular home-to-work commuting, including areas where public transport is limited. The more people join in your area, the easier it becomes to find a reliable match for your daily journeys.

Do I earn anything if I drive and share my rides?

Drivers receive a small fee per trip to help cover fuel and travel costs. It is a simple way to reduce your own commuting expenses by sharing rides you were already making.

How much does it cost to carpool as a passenger?

As a passenger, you typically pay a small contribution towards the trip, which is much cheaper than driving alone or other transport options. In some territories, local authorities subsidise rides, so your cost can be even lower.

How does carpooling with Karos work for me?

Karos matches you with people travelling along the same route at the same time, so you can share daily commutes easily. You can ride as a passenger or offer seats as a driver, meet people from your area and save on travel costs, all through the app.
