Avventura is a platform that allows users to rent outdoor recreational equipment from others in their area, saving space and money compared to owning equipment. It aims to make recreational activities more accessible and affordable by facilitating peer-to-peer equipment rental. The business model is based on AirBnB and takes a 10% commission on each rental transaction. The goal is to launch a pilot program in Western New York where over $20 million is spent annually on recreation.
