Over the past few decades, product firms such as Apple, Boeing, Coca-Cola, and General Electric have been changing the way they do business, moving downstream on their value chains and adopting servitization. In the background, there are economic, technological, and, more recently, institutional changes in motion promoting these changes. Under this phenomenon, carsharing is gaining room as a new business opportunity. Defined as short-term access to a car fleet shared by a group of people, carsharing is calling attention from startups, car rental companies, and car manufacturers alike. At the same time, academic literature is also presenting a growing interest in the activity, investigating its environmental impacts, implications to public policies, and even its different business models. Despite this, studies regarding Brazilian carsharing are scarce, and even fewer are dedicated to local business models. This dissertation was written so to address this gap using a study case methodology for 4 Brazilian operators. Starting with the Business Model and Business Model Innovation concept, all the firms are characterized and analyzed. Results reinforce previous business model categorization in literature with the need to add another category: carsharing business-to-business. Future researches are needed to verify the existence of possible subtypes for this business model.
