Small and medium-sized enterprises (SMEs) generate a significant boost in the national economy; however, the permanence in the market of these companies is relatively short due to the various problems they face, among which the lack of access to financing stands out. The entrepreneurial ecosystem is a gear that moves the economy through the participation of all the actors, and, without a doubt, financing is part of this gear; therefore, the new ways of financing SMEs are a point of discussion since Fintech are companies that promote certain benefits for these businesses. Therefore, the research objective of this paper is to analyze the relationship between Fintech services and the financial characteristics of SMEs in two municipalities. The type of research is quantitative, diagnostic, and correlational. The research method is deductive. The study subjects are SMEs in the northern zone of the State of Mexico. The results show that the entrepreneurs of these SMEs surveyed perceive Fintech as a handy technological tool to finance themselves through crowdfunding platforms. In conclusion, using the Fintech tool as a financing alternative can be used by entrepreneurs who need help obtaining financing due to the high-interest rates they must pay when applying for a loan.
