BUSINESS MODEL

Coinbase

Coinbase makes money from transaction fees. Every time someone buys or sells crypto on the platform, Coinbase takes a cut — typically around 1.5% for regular users, lower for high-volume traders on Coinbase Pro.

For a company that processes billions in daily volume, that adds up fast. In the 2021 bull run, Coinbase generated $7.8 billion in revenue.

Beyond trading fees, Coinbase earns revenue from staking (users earn yield on their crypto, Coinbase takes a commission), USDC interest (Coinbase co-created the USDC stablecoin with Circle and earns interest on the reserves), custodial services for institutions, and its cloud platform for developers building on-chain apps.

Klarna

Klarna makes money from merchant fees and consumer interest. Merchants pay Klarna 3-6% of each transaction — they're willing to pay because Klarna increases conversion rates by 30%+ and average order values by 45%.

On "Pay in 4" (interest-free installments), Klarna makes money purely from merchant fees. On longer financing (6-36 months), Klarna charges consumers interest up to 25% APR.

Klarna also earns revenue from its shopping app (affiliate commissions when users discover and buy from merchants), and from its Klarna Card.

HOW THEY STARTED

Coinbase

Brian Armstrong was working as a software engineer at Airbnb in 2010 when he read Satoshi Nakamoto's Bitcoin white paper. He became obsessed.

At the time, buying Bitcoin meant navigating sketchy exchanges, wiring money to anonymous accounts, and hoping your coins didn't get stolen. Armstrong thought: this is never going mainstream unless someone makes it dead simple.

In 2012, Armstrong got into Y Combinator and co-founded Coinbase with Fred Ehrsam, a former Goldman Sachs trader. Their pitch was straightforward — be the easiest, safest, most regulated way to buy and sell Bitcoin.

While other crypto exchanges were operating in legal gray areas, Coinbase went out of its way to get money transmitter licenses in every US state. It was slow and expensive, but it meant Coinbase was the one exchange your bank wouldn't block.

The first version was bare-bones. You linked your bank account, bought Bitcoin, and Coinbase held it for you.

That custody model — Coinbase holding your crypto — was controversial with crypto purists who preached "not your keys, not your coins." But for normal people who didn't want to manage private keys, it was exactly what they needed.

Klarna

Sebastian Siemiatkowski, Niklas Adalberth, and Victor Jacobsson were students at the Stockholm School of Economics. In 2005, they entered a startup competition with an idea: let people buy things online and pay later.

At the time, online shopping was still new and most people were terrified of entering their credit card details on the internet. The idea was simple — Klarna would pay the merchant immediately, and the customer would get an invoice with 14-30 days to pay.

The competition judges hated it. The idea was dismissed as financially irresponsible and the team didn't win.

But Siemiatkowski pressed on. Swedish e-commerce was growing fast and merchants were desperate for any way to reduce cart abandonment.

Klarna's "pay after delivery" model was a hit because it shifted the risk — customers could receive the product, try it on, and only pay for what they kept.

The first customers were Swedish e-commerce merchants selling fashion and home goods. Klarna handled the invoicing, fraud detection, and collections.

Merchants saw conversion rates jump because customers were more willing to buy when they didn't have to pay immediately.

HOW THEY GREW

Coinbase

Coinbase grew with the Bitcoin price cycle. Every bull run brought a wave of new users who heard about crypto from the news or their friends and Googled "how to buy Bitcoin." Coinbase was almost always the first result.

The company spent heavily on brand advertising including a legendary Super Bowl ad in 2022 that was just a bouncing QR code — it crashed the app from the traffic surge.

The regulatory strategy was the long game. While Binance and FTX grew faster by ignoring regulations, Coinbase spent years and millions getting licensed.

When the regulatory crackdown came, Coinbase was the last exchange standing. Being "the regulated one" went from a competitive disadvantage to the only thing that mattered.

The direct listing in April 2021 was a landmark moment. Coinbase went public via direct listing at a $85 billion valuation — the largest direct listing in history at the time.

It legitimized crypto as an asset class in a way that no Bitcoin price chart ever could.

Klarna

Klarna grew by being embedded at checkout. The strategy was to sign up the biggest online retailers and become a payment option alongside Visa and PayPal.

Once Klarna was at checkout, consumers discovered it organically. The "Pay in 4" button became ubiquitous across fashion, electronics, and home goods retailers.

The Klarna app became a growth engine beyond checkout. By building a shopping app where users could browse products, discover deals, and track deliveries, Klarna turned from a payment method into a shopping destination.

The app has 35+ million monthly active users who start their shopping journey inside Klarna before even visiting a retailer.

International expansion was aggressive. Starting in Sweden, Klarna rolled out across Europe, then into the US, UK, and Australia.

The US became the biggest growth market — American consumers were especially receptive to Pay in 4 as an alternative to credit cards. By 2023, Klarna had 34 million US users.

THE HARD PART

Coinbase

The crypto winter of 2022 nearly broke the company. After the collapse of FTX, Luna, and Three Arrows Capital, crypto trading volume fell off a cliff.

Coinbase's revenue dropped from $7.8 billion in 2021 to $3.1 billion in 2022. The stock went from $342 to $35 — an 90% decline.

Armstrong laid off 18% of the company in June 2022 and another 20% in January 2023.

The SEC lawsuit was existential. In June 2023, the SEC sued Coinbase alleging that it operated as an unregistered securities exchange.

The lawsuit claimed that at least 13 crypto assets traded on Coinbase were securities. If the SEC won, it could have fundamentally broken Coinbase's business model.

The case was eventually settled in 2025 with Coinbase paying a $50 million fine but crucially not admitting that any tokens were securities.

Revenue concentration is a structural risk. Coinbase's revenue swings wildly with crypto prices and trading volume.

In bull markets, the company prints money. In bear markets, revenue evaporates.

This makes it nearly impossible to plan long-term or maintain consistent growth — Wall Street hates unpredictability.

Klarna

The valuation collapse was humiliating. Klarna raised at a $46 billion valuation from SoftBank in 2021.

One year later, they raised a down round at $6.7 billion — an 85% haircut. It was the most dramatic valuation drop in fintech history.

Employee stock options were underwater. Siemiatkowski had to lay off 10% of the workforce.

The entire BNPL category went from hot to radioactive in months.

Credit losses are the existential risk. Klarna is lending money to consumers who want to buy things they can't afford to pay for right now.

When the economy slows, defaults rise. Klarna's credit losses hit $1 billion in 2022.

The company had to tighten underwriting significantly and pull back from riskier markets. The tension between growth (approve more loans) and profitability (reject risky borrowers) defines every quarter.

The IPO in 2025 was a comeback story but with caveats. Klarna went public at $15 billion — a major recovery from the $6.7 billion trough but still less than a third of its 2021 peak.

The company finally turned profitable by slashing costs with AI (replacing hundreds of customer service agents with AI chatbots) and tightening credit standards. But investors remain cautious about the BNPL model's long-term sustainability.
