Stefan Ostwald is the creative mind behind PocketTaxi. Do you think that it is inefficient traveling alone in one car? But at the same time you don’t want to commit yourself to an inflexible carpool? PocketTaxi provides the first commuter optimized dynamic ridesharing service. A world leading matching algorithm enables commuters to find and change carpools with only a few clicks. It makes commuters stay flexible while carpooling, an advantage especially interesting for flextime workers. Ratings, authentication and profiles make the system safe. Stefan is not only the enthusiastic founder, but also programmer, strategist and leader at the same time. Thanks a lot for your vote!
