Open the Coinbase app to check on your crypto, and somewhere in the menu sits a credit card. Tap it. It applies. It approves. It rewards you in bitcoin. At no point does it feel like you left Coinbase. At no point does a bank's logo intrude. That seamlessness is the whole trick - and the company that built it would prefer you never wonder how.
That company is Cardless. It does not put its name on the card. It puts its name on the invoice. Behind the Coinbase One Card, behind Bilt's card lineup, behind cards for Qatar Airways, Avianca, Alibaba.com and the Simon mall network, sits one San Francisco startup quietly running the machinery: the underwriting, the compliance, the bank relationships, the rewards math, the servicing. The brand gets the glory. Cardless gets the rails.
The Problem They SawLaunching a credit card was a two-year ordeal
Here is the inconvenient truth the industry preferred not to advertise: a co-branded credit card is gloriously profitable and miserably hard to build. For most of modern banking, if a brand wanted its own card, it signed a long contract with a large bank, then waited. Twelve months. Sometimes eighteen. Compliance reviews, network integrations, servicing systems, legal sign-offs - a thicket designed, more or less, to keep the club small.
Small clubs are wonderful for the people already inside them. The result was a market where only the largest airlines, hotels and retailers could afford a card program. Everyone else - the fast-growing app, the niche marketplace, the mid-tier brand with loyal fans - was politely shown the door. The economics were sitting right there. The infrastructure to capture them was not.
"After working at Visa and The Points Guy, the founders never found a credit card that worked for them - so they set out to build one for everyone."
- The origin, retoldIt started on a napkin at Whole Foods
Christmas Eve, 2018. A Whole Foods in Bryant Park. Michael Spelfogel and Scott Kazmierowicz sat with a napkin and did something slightly obsessive: they listed every brand they could think of that had a credit card. Then they listed all the ones that should but didn't. The second list was longer. Much longer.
The two had met years earlier as students in Beijing - an unlikely place to incubate a credit card company, but origin stories rarely cooperate with geography. Spelfogel had done a tour of payments: The Points Guy, then Visa, then Lyft as a data scientist. Kazmierowicz came from the money side, with stints at Allen & Company and Goldman Sachs. One understood why cards delight people. The other understood why they make money. Between them, they had the whole equation.
Their bet was simple to state and hard to execute: take the two-year ordeal and turn it into software. Build the underwriting, the compliance and the bank plumbing once, wrap it in an API, and let any brand plug in. They called the result the first mass-market credit card company built since Capital One - a claim that sounds like bravado until you notice how few companies have actually tried.
"They listed every brand with a credit card. Then every brand without one. The second list was the business plan."

What Cardless actually sells is the absence of pain. A partner brings the brand, the audience and the rewards idea. Cardless brings everything that usually takes a year: issuing-bank relationships, underwriting, regulatory compliance, fraud handling, card management and account servicing. The card lives natively inside the partner's own app and website - no redirect, no third-party portal, no jarring handoff to a bank you didn't ask to meet.
The headline number is speed. A program that once took 12 to 18 months can go live in under ten weeks. That compression is the entire pitch. It moves the co-branded card from a privilege of the giant to an option for the merely ambitious.
The products that ride on these rails are getting more inventive. The Coinbase One Card pays up to 4% back in bitcoin and includes a USDC-backed collateralized option for crypto holders - a card that would have given a 2015 compliance officer a small heart event. Bilt runs a multi-tier card suite inside its rewards app. Simon's mall card returns 5% at participating stores. Qatar Airways and Avianca put travel cards in front of U.S. flyers. Alibaba.com offers a Business Edge card to American small businesses. Different brands, different rewards, same engine underneath.
"The brand gets the glory. Cardless gets the rails. Both, conveniently, get paid."
- How the model worksThe partners are names you know
A platform company lives and dies by its logos, and Cardless has accumulated a roster that would be hard to fake. Coinbase. Bilt. Qatar Airways. Avianca. Alibaba.com. Simon. These are not pilots quietly buried in a press release - they are flagship card programs in market, with cardholders spending real money. Transactions on Cardless-issued cards rose roughly 400% year over year, which is the sort of figure that makes investors return calls.
Return them they did. In September 2025, Cardless closed a $60M Series C led by Spark Capital, with Activant Capital, Industry Ventures and Pear VC following on. It pushed total funding past $215M and arrived, conveniently, right after the Coinbase and Bilt deals - timing that reads less like luck and more like a company raising when the story is good. The cap table is its own flex: backers include the founders of Plaid, Bonobos, Flatiron Health and 100 Thieves, plus the ownership groups of the Boston Celtics and Phoenix Suns.
The Cardless Timeline
The revenue bet
Two founders, two halves of the equation
The money half. Came up through Allen & Company and Goldman Sachs before deciding the co-branded card market needed rebuilding rather than refinancing.
The product half. A payments lifer - The Points Guy, Visa, then Lyft as a data scientist - who never found a card that worked for him, so he helped build one for everyone.
Make the bank disappear
The mission is almost paradoxical for a finance company: become invisible. Cardless wants the card to feel like an extension of the brand you already love, with the regulated machinery hidden so completely you forget it's there. Underwriting, compliance, rewards, servicing - the boring, hard, essential half of finance - all absorbed into software so a brand can focus on the experience and a cardholder can focus on the perks.
There is a competitive edge buried in that modesty. The legacy issuers - Synchrony, Barclays, the banks that ran the old club - sell contracts and timelines. The newer infrastructure crowd - Marqeta, Deserve, Imprint - sell pieces. Cardless sells the whole program, fast, to the brands the old system ignored. Whether that moat holds as everyone races toward embedded finance is the open question, and the $60M is, in effect, a bet that it does.
The card is becoming a feature
For decades the credit card was the product and the brand was the decoration. Cardless is betting the order has flipped: the brand is the product, and the card is just one more feature inside the app. If that's right, then the company quietly running the rails - the one that nobody sees - ends up everywhere. Not a card you carry. A capability brands rent.
So go back to that Coinbase app. The card that applies, approves and rewards you without ever feeling like a bank - that is the future Cardless is selling, one logo at a time. The whole point is that you don't notice the company that made it possible. By that measure, the more invisible Cardless becomes, the better it's doing.
