This paper aims to analyse the development process of innovative start-ups with special attention to the equity crowdfunding regulations. The main objective of this analysis is to interpret the effects of equity crowdfunding on the development mechanism of innovative start-ups and compared with other methods of existing loans (for example, the American JOBS Act and the venture capital regulation). The research uses a qualitative method with an exploratory approach. The differential finding of the contribution summarises the main similarities and differences of the financial instruments available to innovative start-ups, highlighting in the new regulation on equity crowdfunding a sustainable financial instrument, capable of reducing the effects of the problem of informative asymmetries.
