Statistics shows that there were 44.8 million adults using the increasingly popular sharing economy services in the United States in 2016. This figure was forecast to increase to 86.5 million by 2021. Choose a sharing economy based company, briefly describe the business model of the company, show the major costs of the company (please be specific and thorough), and discuss the major challenges faced by the company to reach break-even (please limit your answer to 600 words or less)
