Pinwheel.

Somewhere, a paycheck just changed banks. Nobody filled out a form.

A worker opens a new account on her phone. She taps a button that says "move my direct deposit." Eight seconds later her employer's payroll system has a new account number. No PDF. No voided check. No HR email that gets ignored for three pay cycles.

That tap runs on Pinwheel. Most people who use it will never hear the name, which is exactly how infrastructure is supposed to work. Pinwheel sits between roughly 1,800 payroll and HR platforms on one side and the banks, credit unions, and fintech apps on the other. When the two need to talk - about your income, your employment, or where your money should go - Pinwheel is the translator in the middle.

It is, in the company's own framing, the "income layer." Less poetically: it is the plumbing that decides which institution becomes the place your salary actually lands. In banking, that landing spot has a name - primacy - and it is worth a great deal of money.

Your income is the most useful fact about you. It's also the hardest to prove.

For decades, getting your paycheck routed to a new account meant a small bureaucratic ordeal. Find the right form. Track down a routing number. Hand it to a payroll department that may or may not act on it. Banks knew this friction was the reason most "new" accounts sat empty - opened, funded with twenty dollars, then quietly abandoned.

The same wall blocked lenders. To verify someone's income, the usual options were stale pay stubs, screenshots, or bank-statement guesswork - proxies for the truth rather than the truth itself. People with thin credit files or irregular income got the worst of it: real earnings that no system could see.

The founders ran straight into this wall. They were building something else entirely and needed to connect to payroll systems to make it work. They couldn't. The connection didn't exist in any clean, reliable form. So they did the unglamorous thing and built the connection itself.

Three people decided income data should belong to you.

Kurt Lin, Curtis Lee, and Anish Basu founded Pinwheel in 2018 around a stubborn idea: that a person's payroll data is theirs to share, and that putting it back in their hands would make the whole financial system fairer. It sounds like a slogan. In practice it meant signing up for one of the least fun jobs in fintech - building and maintaining connections to thousands of payroll providers, each with its own quirks, and doing it well enough that a bank would bet its onboarding flow on it.

The bet had a regulatory edge to it. Rather than treat payroll data casually, Pinwheel pursued status as a Consumer Reporting Agency under the Fair Credit Reporting Act - the same rulebook that governs the big credit bureaus. For a young API startup, choosing to be regulated is an odd flex. It also turned out to be a moat: accuracy you can be sued over is accuracy banks can underwrite against.

Investors noticed. By January 2022 the company had raised a $50M Series B led by GGV Capital at a $500M valuation, with a guest list that read like a riddle - a card network (American Express), a job board (Indeed), and an asset manager (Franklin Templeton) all writing checks into the same payroll startup.

One API, several jobs - all of them about a paycheck.

Pinwheel's lineup is best read as a single sentence said five ways: get the income data, then do something useful with it.

Numbers are easy to claim. These ones moved money.

The case for Pinwheel isn't a pitch deck - it's a customer list and a set of meters that only go up.

The logos do the rest of the talking. Consumer apps and banks alike route income through Pinwheel:

And the distribution is just as telling. Pinwheel doesn't only sell direct - it rides inside the platforms that banks already run on: Jack Henry, Q2, Alkami, MANTL, Bankjoy, MeridianLink, Blend. When Plaid - the company most synonymous with financial connectivity - names you its preferred partner for deposit switching, that's a competitor conceding a lane.

"Fairer" is doing a lot of work in that sentence. On purpose.

Plenty of companies say they want a fairer financial system. Pinwheel's version is unusually concrete: if real, real-time income is visible and portable, then access to credit and banking can rest on what you actually earn rather than on stale proxies that quietly punish thin files and irregular pay.

That's the through-line connecting every product. The deposit switch isn't just a growth hack for banks - it's the moment a consumer points their paycheck wherever they choose. Income verification isn't just an underwriting tool - it's a way for earnings that no legacy system could see to finally count. The plumbing has a politics, and Pinwheel is fairly open about it.
