One goal guides every action

We are creating a new way of carpooling that is desirable and efficient, wherever it is useful, in order to improve everyday life and accelerate the ecological transition. As a trusted partner of key players in the territories, we are fighting to make carpooling a new standard for everyday transport.

Invent and roll out an efficient and desirable carpooling solution for more humane and more economical daily commutes
As a trusted partner of public authorities and all key players in the territories, create and engage an ecosystem that encourages the development of daily carpooling
Build an ambitious, committed and united team, which pursues our mission in a sincere and responsible way

To support our mission, three statutory objectives were defined.

Key factors for a successful regional car-sharing network

Invent and roll out an efficient and desirable carpooling solution for more humane and more economical daily commutes
Our technology reliably connects carpoolers for their commutes and integrates them seamlessly into the existing public transport network. Through intelligent matching algorithms, intermodal route planning, and real-time validation, individual car trips transform into measurable, scalable mobility solutions, especially in places with poor public transit connections.
As a trusted partner of public authorities and all key players in the territories, create and engage an ecosystem that encourages the development of daily carpooling
A functioning carpooling network doesn’t just happen by itself. We support cities, regions and companies in the targeted development of carpooling solutions – from strategy and the involvement of key employers right through to active on-the-ground communication. This enables us to quickly reach the critical mass that is essential for sustainable adoption in commuter travel.
Build an ambitious, committed and united team, which pursues our mission in a sincere and responsible way
Financial incentives make carpooling an attractive option for everyday commute. Drivers receive a share of the costs for each passenger they carry, whilst passengers often travel for free as part of their public transport ticket. This combination reduces costs, increases the occupancy of existing vehicles and promotes the long-term use of shared mobility.

What does being a mission-driven company mean ?

Introduced by France's PACTE law, the mission-based company framework enables companies to formally embed social and environmental objectives into their corporate purpose.

Turning our commitments into a long-term framework

Since Karos was founded, impact has been at the core of our business: accelerating the ecological transition, improving purchasing power and making everyday mobility more accessible across territories.
In June 2024, for our 10th anniversary, we officially became a mission-based company. By embedding our purpose and social and environmental objectives into our status, we made our mission a long-term framework for our strategy and development.

We measure success through impact

Our impact indicators are integrated into an Impact Business Plan, monitored alongside our financial Business Plan. They are tied to annual targets and help us measure our social, environmental and territorial impact.

An independent perspective on our mission

Our Mission Committee brings together experts from impact, sustainable mobility, investment and entrepreneurship. Its role is to provide an external, independent and demanding perspective on how we deliver our mission.

Transparency is part of our commitment

Our Mission Committee independently reviews how we deliver against our statutory objectives and reports on the progress made, results achieved and areas for improvement.
Its first report covers the period July 2024 to December 2025 and concludes that Karos has built solid foundations for its mission, with strong overall alignment between the company's strategy and its commitments.
