Stripe

Stripe charges a flat 2.9% + $0.30 per transaction. That's it.

No setup fees, no monthly fees, no hidden charges. The simplicity is the product.

When a customer pays on a website using Stripe, Stripe handles everything — fraud detection, currency conversion, bank transfers, tax calculation, compliance. The merchant just sees money arrive in their account.

On top of the core payments, Stripe has built an entire financial infrastructure stack. Billing for subscriptions, Connect for marketplace payments, Atlas for incorporating a company, Issuing for creating virtual cards, Treasury for banking-as-a-service, and Radar for fraud prevention.

They're basically building the financial plumbing for the entire internet.

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.

Patrick Collison was 19. His brother John was 17.

They had already built and sold a company — Auctomatic, an eBay auction tool — for $5 million while still teenagers in Limerick, Ireland. Patrick went to MIT, John went to Harvard, and they both dropped out because they had a better idea.

The idea was embarrassingly obvious in hindsight. In 2010, accepting payments on the internet was a nightmare.

You had to get a merchant account, negotiate with a payment processor, deal with a gateway provider, handle PCI compliance, and write thousands of lines of code. It took weeks or months.

The Collisons thought it should take five minutes.

They built a simple API — seven lines of code — that let any developer start accepting credit card payments immediately. No merchant account.

No paperwork. No phone calls with banks.

Just paste seven lines of code and you're in business. They originally called it /dev/payments, then changed it to Stripe in 2011.

Peter Thiel and Elon Musk — the PayPal mafia — were among the first investors. Sequoia and Andreessen Horowitz piled in soon after.

The Collisons had built exactly what every developer on Earth had been wishing for.

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.

Stripe

Stripe grew almost entirely through developer love. They didn't hire a sales team for years.

They didn't run ads. They just built the best developer documentation anyone had ever seen and let word of mouth do the rest.

The developer-first strategy was deliberate. The Collisons realized that in a startup, the developer usually decides which payment provider to use.

If you make the developer happy, you win the company. Stripe's API documentation became legendary — clear, beautiful, with working code examples in every language.

They also grew by growing with their customers. Early Stripe customers included tiny startups that later became giants — Lyft, DoorDash, Instacart, Shopify.

As those companies scaled to billions in revenue, Stripe's processing volume scaled with them. Stripe didn't need to acquire new customers because its existing ones kept getting bigger.

The international expansion was methodical. Instead of launching everywhere at once like Uber, Stripe carefully added country after country, making sure each one worked perfectly with local payment methods, currencies, and regulations.

By 2024 they were processing payments in 195 countries.

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.

Stripe

Valuation whiplash. In 2021, Stripe hit a peak valuation of $95 billion during the fintech boom.

By 2023, they had to mark it down to $50 billion during the tech correction — a 47% drop that made headlines everywhere. Employees who had been paper millionaires suddenly weren't.

The valuation has since recovered to $91 billion after a secondary share sale in 2025, but those two years were rough for morale.

Competition is relentless. Adyen, the Dutch payments company, has been eating into Stripe's enterprise market.

Square (now Block) competes on the small business side. PayPal is everywhere.

New fintech players pop up constantly. The payments business has razor-thin margins and everyone is fighting for the same 2.9%.

Going public is the elephant in the room. Stripe has been expected to IPO for years.

Investors, employees, and the media keep asking when. The Collisons have consistently said they're in no rush, but with $8.7 billion raised and thousands of employees holding stock options, the pressure to provide liquidity is enormous.

As of 2025, they've opted for secondary sales instead of a public offering.

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.

Stripe

Stripe Payments is the core — accept credit cards, debit cards, Apple Pay, Google Pay, and 135+ payment methods in 195 countries. Stripe Connect lets marketplaces and platforms pay out to sellers (Shopify, Lyft, DoorDash all use it).

Stripe Billing handles subscription and recurring billing. Stripe Atlas lets you incorporate a US company from anywhere in the world — fill out a form, get a Delaware C-corp, bank account, and tax ID in days.

Stripe Radar uses machine learning to block fraud in real time. Stripe Treasury lets platforms offer banking services to their customers.

Stripe Tax automatically calculates and collects sales tax in every jurisdiction.

Coinbase

Coinbase is the consumer trading platform — buy, sell, and hold 250+ cryptocurrencies. Coinbase Advanced Trade (formerly Coinbase Pro) is the lower-fee, more sophisticated trading interface.

Coinbase Wallet is a self-custody wallet where users control their own keys. Coinbase Prime is the institutional platform for hedge funds, family offices, and corporations.

Base is Coinbase's own Layer 2 blockchain built on Ethereum, designed for cheap, fast transactions. USDC is the stablecoin Coinbase co-created with Circle — pegged 1:1 to the US dollar with over $30 billion in circulation.

Coinbase Commerce lets businesses accept crypto payments.
