Plaid

Plaid is the financial-data plumbing behind many apps that need bank accounts, transaction history, or balance checks without building that connection themselves. By our assessment, its real strength is that it lets products hook into banking data through one clean integration instead of each company negotiating a separate maze of connections. The obvious downside is dependence: if a product is built on Plaid, it inherits the rules, coverage, and friction of the banking links it sits on top of. In practice, the experience is usually invisible to the end user until a login, consent screen, or account-link step appears. That makes it feel less like a consumer brand and more like infrastructure, which is exactly where it sits among fintech providers. It is a US company, and it is mostly for apps and services that need reliable account connectivity rather than for anyone looking for a public-facing financial app.
