Fleety was the first Peer-to-peer carsharing of Brazil. I worked at the early stages of the project: prototyping and validating the idea. The first city where fleety worked was Curitiba. Today the platform runs in São Paulo and Florianopolis. Getting involved with collaborative economy was special for me because I had thd opportunity to study and understand the behaviour of the Brazilian user, how they interpret this collaborative culture and how they get involved. The biggest challenge of this project was to overcome the insecurity and the user's distrustful.
