Karos

Karos is a French mobility startup that has developed an AI-powered carpooling platform specifically designed for short-distance commuting journeys — the type of trips that are hardest to serve with traditional public transport but account for a significant share of urban congestion and emissions. The platform uses machine learning algorithms to analyse commuters' travel patterns, schedules, and preferences, automatically matching drivers and passengers for shared journeys without requiring users to actively search for matches. This proactive approach dramatically increases carpooling adoption rates compared to traditional ride-sharing platforms. Karos works closely with local authorities and regional transport authorities across France, integrating its service into public transport networks as a complement to buses, trains, and trams. The platform has facilitated millions of shared journeys, with each matched ride directly reducing the number of single-occupancy vehicles on French roads. Karos has also developed partnerships with major employers, enabling workplace commuting programmes that reduce parking demand and carbon footprints at corporate sites.
