Chime

Stripe

Chime

Chime makes money almost entirely from interchange fees. Every time a Chime member uses their debit card, the merchant pays a swipe fee (typically 1-2% of the transaction).

Chime keeps a portion of that interchange. The model only works at scale — Chime needs millions of members making thousands of transactions to generate meaningful revenue.

But with 22 million members, the math works. Chime also earns interest on member deposits and fees from optional instant transfer services.

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.

Chime

Chris Britt spent years working in financial services — at Visa, Green Dot, and other companies — and kept seeing the same thing: banks made a disproportionate amount of their revenue from fees charged to their least wealthy customers. Overdraft fees alone generated $35 billion annually for US banks.

The average overdraft was $36 for a $24 transaction — that's a 150% fee. Poor people were subsidizing free checking for rich people.

In 2012, Britt co-founded Chime with Ryan King (CTO) to build a bank account designed for people living paycheck to paycheck. The core promise was radical: no monthly fees, no minimum balance, no overdraft fees, ever.

You'd get your direct deposit up to two days early (because Chime could release funds as soon as they were notified of a pending deposit, while banks sat on the money for two extra days), and you could overdraft up to $200 without any penalty through a feature called SpotMe.

The product launched in 2014 and grew slowly at first. But the target market — working-class Americans frustrated with bank fees — was enormous.

Once people tried Chime and realized they'd never see another $35 overdraft fee, they told everyone they knew.

Stripe

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.

Chime

Chime grew through massive direct-to-consumer advertising. TV commercials, YouTube ads, podcast sponsorships, Instagram campaigns — all hammering the same message: no fees, get paid early, no overdraft penalties.

The message resonated with a demographic that traditional banks ignored or exploited: working-class Americans earning $30,000-$75,000 per year.

The "get paid early" feature was the killer hook. Chime releases direct deposits up to two days before payday.

For someone living paycheck to paycheck, getting paid on Wednesday instead of Friday is life-changing. It reduced the need for payday loans and covered emergency expenses.

The feature spread through word of mouth faster than any ad campaign.

Simplicity was a deliberate choice. Chime doesn't offer investing, crypto, or dozens of products.

They do one thing — be a great bank account for everyday Americans — and do it well. While competitors like Cash App and Revolut chased feature bloat, Chime stayed focused on the core banking experience.

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.

Chime

Chime is not actually a bank. They're a fintech company that partners with Bancorp Bank and Stride Bank to hold deposits and issue cards.

This distinction matters because Chime doesn't have the regulatory protections and permissions that come with a bank charter. In 2021, the state of California ordered Chime to stop calling itself a bank in advertising.

The regulatory status limits what products Chime can offer and adds counterparty risk.

Unit economics have been questioned. Chime spends heavily on customer acquisition — hundreds of dollars per member through advertising.

If members don't use their Chime card frequently enough, the interchange revenue doesn't cover the acquisition cost. Chime needs high engagement to make the model work, and some members treat Chime as a secondary account rather than their primary bank.

The path to IPO has been repeatedly delayed. Chime was expected to IPO in 2022 but the fintech market crash made that impossible.

The company has reportedly been preparing for a 2025 listing, but at a valuation significantly below its 2021 peak of $25 billion. The longer the company stays private, the more pressure employees with stock options face.

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.

Chime

Chime Spending Account is the core — a fee-free checking account with a Visa debit card. Chime Savings Account offers automatic round-ups and a competitive APY.

SpotMe lets members overdraft up to $200 with no fees — Chime covers the difference and deducts it from the next deposit. MyPay gives members access to earned wages before payday.

The Chime Credit Builder card helps members build credit by reporting on-time payments to all three bureaus — no credit check required, no interest, secured by your own money. Instant Transfers move money between Chime members instantly.

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.
