About Plaid

Plaid operates the largest open banking data network connecting applications to over twelve thousand financial institutions across twenty countries. The platform serves as the infrastructure layer that powers account aggregation for major fintech applications, enabling developers to verify bank account ownership, check real time balances, and initiate secure bank transfers without building direct integrations with disparate banking cores. One in two adults in the United States already use services built on Plaid infrastructure, including popular apps for investing, payments, and personal finance management.

The platform distinguishes itself through comprehensive coverage of credit unions, neobanks, and major commercial banks, combined with machine learning powered fraud detection that assesses transaction risk signals. Developers implement Plaid through Link, a client side component that handles credential management and multi factor authentication flows, reducing implementation complexity while maintaining bank grade security standards. The API supports diverse use cases ranging from automated savings transfers and lending decision engines to brokerage account funding and income verification for gig economy workers.
