In the context of mass entrepreneurship and innovation, makerspace as a new type of shared and platform entrepreneurial service company, has developed rapidly in recent years. At present, makerspace is facing many problems such as seeking government policy support, conducting mergers and acquisitions and listing business, expanding financing channels, and introducing high-quality innovation and entrepreneurship projects. These problems cannot be solved without accurate valuation. Based on the fuzzy mathematics theory to modify the real option model, the FCFF model and the real option model are combined to build a comprehensive real-estate valuation model based on fuzzy real options. The overall value of makerspace is evaluated, that is, the FCFF model is used to evaluate the operating asset value of makerspace, and the real option value of makerspace is evaluated by the fuzzy real option method. In order to verify the feasibility of the comprehensive model of makerspace valuation, a representative Dark Horse in makerspace industry was selected as a case for empirical analysis, and compare the valuation results with the valuation results obtained by simply using the real option pricing model and the market value of Dark Horse on the valuation base date. The results show that the enterprise value of Dark Horse calculated by using the improved comprehensive model is closer to the market value on the valuation base date.
