At Karhoo, we are creating the largest and most transparent marketplace for ground transportation: the Karhoo Mobility Exchange.

By aggregating ground transport around the world, with regulated/licensed taxi and PHV fleets, we will give greater choice to consumers and corporates alike, bring new opportunities and data for the private and public sector, and help to enable ‘smart cities’ for citizens everywhere.

Karhoo, the first fully-integrated global, neutral, booking platform for regulated Taxis and PHVs was bought out of administration in January 2017, funded by RCI Bank and Services, the financial services provider for the Groupe Renault brands in the world and for the Nissan Group brands mainly in Europe.

RCI Bank and Services operates at the crossroads of three challenging worlds: cars, banking and services and is backing Karhoo via Flit Technologies Ltd, a new venture funded by RCI Bank and Services.
