MonkeyParking
MonkeyParking is a mobile app that allows users of the service to auction parking spaces to other users. The company was founded in 2013 by Paolo Dobrowolny, Federico Di Legge and Roberto Zanetti.
The app (first allowed users to auction off public, city-owned parking spots to the highest bidder) is now focused on private parking spot: property owners are allowed to grant permission for others to park in front of their driveways.
