This document summarizes the findings from onboarding to 30 crowdinvestment platforms. It finds that 97% of platforms asked similar registration questions and required similar documents. The total onboarding time varied significantly between platforms, from just a few minutes to over 20 minutes. The number of questions in applications ranged widely as well, from under 10 to over 70. The document identifies Republic, Wefunder, and Fundrise as having particularly easy and intuitive onboarding processes. It was conducted by researchers at Byzantine Solutions and A.ID to study user experience and compliance requirements in crowdinvesting.
