Crowdfunding refers to accumulating small sums of money from the general public through the Internet for a collective larger amount to fund small or medium-sized ventures in exchange for some benefit. The contribution can be as a donation (for no material reward), a purchase (for getting a reward in return), debt (to get money returned), or equity (for sharing future profit). The three main actors in crowdfunding are the initiators (the venturers), the backers (the crowd members who fund), and the crowdfunding platforms (the intermediaries). The crowdfunding campaign’s survival and success depends on engagement from the crowd. Using a qualitative research method, this dissertation aimed to understand the backers’ engagement with four crowdfunding campaigns selected from the leading crowdfunding platform, Kickstarter, through processual analysis. Buildingon the integrative framework of service-dominant logic, engagement, and customer journey, the underlying mechanism of the backers’ engagement at the personal (micro) and interpersonal (meso) levels were explored. Based on the motivation and contribution pattern, the backers were segmented into four engagement roles: benefactors, patrons, shoppers, and utilisers. A deeper analysis showed how the engagement intensity, duration, valence, and engagement properties shaped over time across these roles. The insights from the findings in the dissertation carry managerial and policy implications.
