A significant factor could be the user experience on the Venmo platform. If adding a bank account is overly complicated or takes too long, users may choose to skip it out of convenience or frustration. The user interface and overall ease of use are essential for app engagement and retention. Consequently, Venmo needs to focus on simplifying its processes and enhancing the app's user-friendliness. Moreover, changes in banking policies or regulations could also influence users' choices to connect their bank accounts. For example, banks might have implemented stricter rules regarding third-party access to account information, making it more challenging for users to link their accounts with Venmo. Finally, the absence of a compelling value proposition for linking a bank account may also be a factor. If users do not perceive clear advantages or incentives in connecting their bank accounts, they may consider it unnecessary. Therefore, Venmo should investigate ways to offer more value to users for adding their bank accounts, such as cashback rewards, discount vouchers, or expedited transactions.
