In the world today, people are more focused on their healthy lifestyle and hence from time to time do exercise on an amateur level. In Finland, the most popular sports are Ice hockey and Football, other sports such Tennis and Padel are gaining in popularity. To respond to this growing interest from this group of people it is necessary to create a simple to use platform which interacts between the customer and the Tennis clubs. The goal of this thesis is to find all the obstacles and analyse the customers behaviour to build a marketplace platform combining all the necessary tech solutions in the market. The research shows that the current tools/websites in the market are lacking information and are built different from one another. It not only gives confusion but also it discourages the person in moving forward with the search. Marketplace Sports Platform is primarily an answer to the unsatisfied demands of amateur racket players in Finland which facilitate the access of all the information needed using the same portal. The thesis analyses the players behaviour and the tools, websites and data used to play Tennis in Finland. It also describes to the reader the importance of a marketplace platform to connect between the buyers and sellers and providing all the necessary information to help ease their journey and therefore experience a user-friendly platform.
