parku is a young Sharing-Company that makes parking spaces used more efficiently and simplifies the parking space search. We offer both private parking space owners and companies the opportunity to temporarily rent their parking spaces while they are not used. In urban areas and near the city center, this represents an attractive additional income without much effort. The extra revenues finance the owner's parking rent up to 100% of the net fee. Besides the financial incentive, Parking-Sharing relieves the parking situation in big cities because it will drastically reduce the search traffic for a free space. According to official studies, the search traffic amounts to up to 30% of inner-city traffic and increases noise and pollution for local residents.
