This paper aims to provide an in-depth understanding of the growth of sharing platforms. As the mobility sector witnesses most activities, a case study of shared mobility platform is identified. The case represents a successful “Car-As-A-Service” platform that has consequently created peer-to-peer (P2P) markets for ridesharing and car rental services, and established a critical mass of users by increasing the supply side of the P2P markets through leasing services. The leased car remains in the closed loop of the platform to provide additional shared mobility services to its users.
