The problem of monetization of web pages and applications is one of the biggest problems that user experience and interface designers meet. The way that monetization of a particual web page is done affects all of the further decisions in business, design and development teams. In this thesis research will be done to show which methods of monetization are possible in digital products, how design affects business decision making, and how to use gamification to improve overall user experience and improve the monetization process for the web applications. Also, research of how gemification affects digital and physical products will be done, and the way gemification affects user behavior and changes that will lead to desired goals, will be presented. The design process will be connected to the Lumen Development competition, where the final goal was to make a web app, and through that example it will be shown how previously presented terms create a great user experience. Research will be made about the competition, and by doing the market research, target groups, gamification of business, and validation of user experience, a price of the product will be determined. The price of the product will need to satisfy the business needs, and in a same time offer a value to the user that competition doesn't provide. By doing this, a problem of monetization will be solved – how much to charge the product to the user, when to charge and how to keep a satisfying level of user experience when using the web app. The goal of the web app itself is to offer users possibility to „rent out“ PC power of someone else's computer for the gaming purposes, and give users that have strong PC'S for gaming a possibility of making money by „renting out“ their PC.
