Scott
Kazmierowicz.
He looked at the American credit card and decided the brand, not the bank, should own it. Then he got Coinbase, Bilt and Qatar Airways to agree.
The co-founder, before the term sheets. A studio frame from the early Cardless days - the half-smile of someone who already has the napkin in his pocket.
01 // What he is building
The bank disappears. The brand stays.
Scott Kazmierowicz runs a company that wants to make itself invisible. Cardless, the San Francisco fintech he co-founded in 2019 and leads as CEO, builds the machinery behind co-branded credit cards - the underwriting, the app, the rewards, the compliance, the customer service - and then hands the front of the card to somebody famous. You see Coinbase. You see Bilt. You see Qatar Airways or Alibaba. You do not see Cardless. That is the point.
The thesis is blunt: brands, not legacy banks, should own the relationship with the person holding the card. For decades, launching a co-branded card meant a multi-year negotiation with an incumbent issuer, a clunky product, and economics built around fees and friction. Kazmierowicz pitches the opposite - a modern, mobile-first stack a brand can switch on, with terms it actually controls.
By 2025 the bet was paying off. Household names had begun pulling their card programs off legacy banks and rebuilding them on Cardless. Transaction volume was growing 400% year over year, with spending levels the company says run well above traditional bank-issued cards. In September 2025 it raised a $60 million Series C led by Spark Capital, pushing total funding past $170 million. In 2026, Fast Company called it one of the most innovative companies in the world.
For Coinbase, Cardless built a crypto-native experience: rewards that live in Bitcoin and other assets, managed inside the app. For Qatar Airways, it embedded credit straight into the Privilege Club app so a traveler could apply, spend and earn loyalty without leaving the airline's world. Different brands, same trick - the financial plumbing stays hidden, the brand stays loud.
02 // The origin
A napkin, a Whole Foods, and a list of nearly 100 brands
It started on Christmas Eve 2018, in the Whole Foods at Bryant Park in Manhattan. Kazmierowicz and Michael Spelfogel sat scribbling on the back of a napkin, trying to name every brand that had ever put out a credit card. They got close to 100.
Then they noticed the thing that became the whole company: of all those cards, only one belonged to a brand younger than 20 years old. Uber. Everything else was a relic of a slower era. The credit card had stopped being something new brands could offer their customers. They decided to fix that - to build, as they framed it, the first mass-market credit card company since Capital One.
What they did next is the tell. They spent much of the first year not building. They talked to hundreds of brands, fintech executives, banks, card networks and consumers before writing the product that mattered. The first card to actually ship was for the Cleveland Cavaliers, an NBA team, in March 2021.
We exist to make consumer credit products in the U.S. more fair, useful and respectful of each person's potential and dignity.

03 // The idea behind the idea
Credit, treated as a design problem
Ask most people about their credit card and you get a shrug at best. Useful, sure. Loved, never. Kazmierowicz, a computer scientist by training, looks at that gap the way a product designer would, not a banker.
He maps products on two axes - useful and loved. Traditional credit cards, he argues, sit stubbornly in the bottom-right: indispensable but unliked, propped up by enormous customer-acquisition costs that push the industry toward predatory fees and high interest. The corner he wants is top-right, where a product is both genuinely useful and genuinely loved. He has a name for it.
Getting there, in his telling, is a human-centered design challenge as much as a financial one. Cardless's whole structure - brand on the front, transparent terms, rewards that mean something - is an attempt to drag the credit card out of the unloved corner. The business model is meant to reward engagement rather than extract from frustration, which is a polite way of saying the incentives are supposed to point at the customer for once.
It is an unusually idealistic frame for an industry famous for fine print. Whether or not you buy it, it explains a lot about how he runs the company - and why the founder of a credit-card platform spends his time writing about dignity.

Three things that won't fit on a pitch deck
Surfing, guitar, and FedEx. That is, verbatim, the interest list on his Medium bio. Two hobbies and one logistics company - read into the third one what you will.
A grocery store as a war room. The billion-dollar idea was sketched in a Whole Foods on the one night most founders are off the clock - Christmas Eve.
Engineer first. A Stanford CS grad who studied AI, he came up through Goldman's code base before he ever sat across from a brand's CFO.
06b // The operator
The engineer who learned to wait
Most credit-card stories are told by bankers. This one is told by a programmer. Kazmierowicz studied computer science at Stanford, with a focus on artificial intelligence and a second love for economics, and he carried both into the working world before he carried them into a startup. He wrote software and worked securities strategy at Goldman Sachs, then crossed to the deal side as an investment banker at Allen & Company. It is an unusual pairing - the person who builds the system and the person who values it - and it shows up in how Cardless is put together. The product is engineered like infrastructure; the pitch is argued like a thesis.
The most counterintuitive thing about his first year as a founder is what he did not do. He did not rush a card to market. He and Spelfogel treated the launch like a research project, interviewing hundreds of brands, banks, networks, fintech operators and ordinary cardholders before committing to a design. In a venture culture that rewards shipping fast, choosing to listen for a year is its own kind of conviction. The payoff was a product built on what the market actually said it needed, rather than what two founders assumed it wanted.
That patience also explains the company's shape. Cardless is not chasing a single hero product; it is building a platform that other companies plug into. Coinbase wanted rewards denominated in crypto. Qatar Airways wanted credit folded into its loyalty app. A basketball team wanted a card its fans would be proud to pull out at the arena. One platform, many faces - and a founder content to let each partner take the spotlight while the engine underneath stays his.
06c // The wager
What he is actually betting on
Strip away the partnerships and the funding headlines and the bet is simple: that the next great credit cards will come from brands people already love, not from banks people merely tolerate. If he is right, the legacy issuer becomes a back-office utility - necessary, invisible, replaceable - while the brand owns the moment a customer reaches for the card. Cardless is positioning itself as the layer that makes that swap possible, the infrastructure that lets an airline or an exchange or a sports franchise behave like a card company without becoming one.
The early evidence is on his side. Brands have started moving existing programs off incumbent banks and rebuilding them on Cardless, which is a far harder sell than signing a brand-new card - it means convincing a company to rip out something that already works. Spending on the cards is growing fast, and the roster of partners reads like a list of the brands a person might genuinely want in their wallet. The Series C money is earmarked to widen that roster, deepen existing programs and stretch the product range further into embedded finance.
None of it guarantees the outcome. Credit is cyclical, regulation is heavy, and the incumbents he is trying to route around are some of the largest institutions on earth. But Kazmierowicz has shown a pattern worth watching - listen longer than is comfortable, design for the person holding the card, and let the brand be the hero. For a company built to be invisible, it has become surprisingly hard to ignore.
The magic of Pear is their intense focus on us as people and founders. They pushed us and gave us some hard-won advice along the journey.
