The current graduation project aims to implement a digital environment application for the player trading market for football clubs. This proposal was inspired by the work of former student, Frederico de Freitas Martins Gall, who presented in Public and Business Administration at Fundação Getúlio Vargas, in the year 2021, a business plan for TransferWindow. In his monograph, Fred sought as his main objective, the financial viability of building a digital application for the negotiation of players, which, through the analysis of the Brazilian football market, could justify the option of acquiring football professionals. The project presented seeks to develop, detail and materialize the solution as a whole. Information used in this document, based on the TCC research, will be duly cited during the presentation of the main topics and in the relevant bibliography. This document is currently not available online. Therefore, the project s main objective will be to develop a solution aimed at the transfer market between clubs, for soccer athletes in Brazil. Seeking to meet the needs of the three stakeholders of this market, namely, 1- Clubs; 2-Businessmen and 3-Players, TransferWindow seeks to professionalize and streamline the negotiation process of football professionals, avoiding the excessive amount of third parties involved in the hiring processes and making this operation less exhausting. With the intention of increasing the number of transfers carried out between clubs, TransferWindow will seek to provide as much information as possible and will use technology to make this process more transparent and less complex, both for the club and for the athletes through its agents.
