Plaid builds the software pipes that let apps securely connect to your bank account so you can move money and share financial data.
Plaid is the plumbing behind a lot of the finance apps you already use. When you open a budgeting app, a investing app, or a payment service and it asks you to "link your bank account," there's a good chance Plaid is what pops up asking for your bank username and password. You log in, Plaid checks with your bank that it's really you, and then it hands a secure, read-only key to the app so it can see your balances and transactions without ever touching your actual money. The whole point is to replace the old, clunky way of doing this—where you'd have to manually type in account numbers or hand over your real banking credentials to every random app—with a single, trusted front door.
The company makes money by charging the apps and financial companies that use it. Those customers pay per connection, or per check, or per data pull, depending on what they need. It's a toll-booth business: Plaid doesn't lend money, hold deposits, or take investment risk. It just sits in the middle, verifying that you are you and that the account is real, and collects a small fee every time an app needs to do that. Its biggest customers are fintech startups, brokerage apps, lenders checking income, and payment companies that want to move money from your bank to somewhere else. That position makes Plaid both powerful and exposed. It became a household name among developers because it covered thousands of banks with one integration—build once, connect everywhere. But banks grew wary of handing over customer data, and regulators started paying attention to who gets to see your financial life. A big proposed acquisition by Visa for $5.3 billion fell apart in 2021 after the government sued to block it, which was a turning point: Plaid stayed independent, raised money at a much higher valuation, and pushed into new areas like identity verification, income checks for lenders, and payment initiation—basically moving from "read my bank data" to "move my money and prove who I am."
The quiet risk in the business is that its core product depends on banks letting it in. As open-banking rules take shape in the US and banks build their own APIs, Plaid has to keep proving it adds value rather than just sitting in the middle taking a cut. It has responded by buying companies, expanding into fraud and identity tools, and pitching itself as the neutral layer that works with everyone instead of a single bank's walled garden. For now, it remains one of the most important unglamorous companies in fintech: you rarely think about it, but a huge chunk of the apps that touch your money quietly run through it.

Plaid is estimated to handle about 70% of America's open-banking market
When an app like Venmo or Robinhood asks to peek at your bank account, the software doing the asking is very often Plaid's. One industry estimate puts Plaid at about 70% of the US open-banking market, meaning the company sits between most American bank accounts and the apps that want to use them. That near-default position is how it earns money: apps pay Plaid each time a customer links an account. Source: Business Information Industry Association, data from 2026
Zach Perret and William Hockey had worked at Bain, and when they tried to build financial technology, they hit the same wall everyone did: banks had no single, clean way to share account data, and what came back was messy. So they built plumbing that handed back tidy transaction data, and an app on top of it won the TechCrunch Disrupt hackathon that year. In private beta, with a few big banks, they pitched Plaid as the modern API for banking data: one doorway to connect an app to a bank account.
For a name, a whiteboard drawing did the trick: an algorithm that located a transaction left a cross-hatched pattern that looked like plaid fabric. Throwing in a quick check of the plaid.com domain made it official.
When Plaid opened its platform to everyone, the apps it powered read like a who's who of new finance: Venmo, Robinhood, Coinbase, Acorns, LendingClub. Plaid had become the invisible layer connecting money apps to bank accounts.
Visa agreed to buy Plaid for $5.3 billion, a huge vote of confidence. Regulators, though, worried the deal would hurt competition, and it fell apart. Plaid stayed independent, and the failed sale ended up looking like a favor: later funding rounds valued the company well above what Visa had offered.
With fintech valuations booming, Plaid raised a large round in 2021 that valued the company at $13.4 billion. The plumbing behind the apps had become one of the most valuable private companies in finance.
A few years later, Plaid raised $575 million from big investors such as Franklin Templeton, Fidelity and BlackRock, but at a $6 billion valuation: less than half its 2022 peak, though still above Visa's old offer. The company had kept growing, with revenue up 24%, and was back to positive operating margins.
Plaid moved into a new chapter built around artificial intelligence, unveiling a foundational model for what it called intelligent finance. AI companies were already a fifth of new customers onboarded the year before, a sign of where the money apps were heading.
A tender offer put Plaid at an $8 billion valuation, up 31% from the year before, as investors warmed again. The bump reflected fresh momentum and Plaid's growing relevance in the age of AI.
