Equity crowdfunding is a new way for seed stage start-ups to generate initial capital and, as such, raises questions around the choices made by investors within this area. Understanding it is important for investor protection, as investors are generally unaware of the factors that can influence their decisions. However, investing in equity crowdfunding places the investor in a unique decision-making framework, in which resources such as images, videos and storytelling are all mobilized by entrepreneurs and platforms as tools of persuasion. This context thus seems to favor more holistic and emotional decision-making, rather than a process that is rational and analytical. This first volume centers on the emotional and axiological determinants of choice. A transdisciplinary theoretical analysis is carried out, combining different fields within the social sciences, primarily finance, marketing and psychology. This state of the art leads to the emergence of an original theoretical framework for understanding investment choices in equity crowdfunding.
