What is Plaid?
Plaid is a financial account connectivity tool developed by Plaid Inc. that enables fintech developers, financial institutions, and businesses to securely connect financial accounts to applications. It acts as a regulated coordination layer, facilitating data transfer through a first-class API surface. Plaid's core function is to facilitate secure communication between financial institutions and third-party applications. When a user links their bank account to a Plaid-powered app, Plaid encrypts the requested financial data, such as account balance or transaction history, and securely shares it with the application without sharing the user's login credentials with the app itself. Plaid connects to over 12,000 financial institutions across the United States, Canada, and Europe, powering applications like Venmo, Betterment, You Need a Budget, and Robinhood. Recent developments include the launch of AI data tools and Guaranteed Payments in May 2026, enhancing ACH transactions and categorization accuracy by 13%.
