StreetFair is an iPhone app designed as an online marketplace for neighborhoods, facilitating users to discover and engage local home maintenance businesses recommended by their neighbors. The platform showcases top local companies operating in the area and enables users to participate in upcoming services already planned by their neighbors. One of its unique features is the group discount concept, where as more neighbors sign up for a service, the price decreases for all participants. This innovative approach benefits consumers by providing high-quality services endorsed by their neighbors, helps service providers enhance efficiency through route density, and collectively allows neighborhoods to reduce traffic congestion and lower their carbon footprint.
