Most people have at some point linked a bank account to a budgeting app, a trading app, or a payment app in a few taps. Almost none of them have thought about what's actually happening behind that step.
The connection problem fintech apps all shared
Every bank has its own systems, and historically there was no standard way for an app to securely ask "can you verify this person's account and balance?" Plaid built that connective layer once, so thousands of fintech apps didn't each have to negotiate integrations with thousands of individual banks.
Infrastructure you only notice when it breaks
When it works, a user never thinks about Plaid at all — they just see their bank account connected. It's infrastructure in the purest sense: valuable almost exactly in proportion to how invisible it manages to be.
It's the same principle behind any good tracking or logistics layer — the technology underneath a move or a delivery should be doing real work precisely when the person using it doesn't have to think about it.
