Uber

Uber is a marketplace that connects riders with drivers. You request a ride through the app, the nearest driver accepts, picks you up, drops you off, and Uber takes a cut — typically 25-30% of the fare.

The driver keeps the rest. Uber doesn't own any cars.

They don't employ any drivers. They built a $150 billion company by being the middleman with a really good app.

The model expanded into Uber Eats (food delivery, same concept — restaurants cook, drivers deliver, Uber takes a cut), Uber Freight (connecting truckers with shippers), and advertising. The advertising business is quietly enormous — Uber has data on where millions of people go every day, and brands will pay handsomely for that.

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.

Uber

The idea started in Paris in December 2008. Travis Kalanick and Garrett Camp were at the LeWeb tech conference and couldn't find a cab.

Camp had been obsessing over the idea of summoning a car with your phone. He bought the domain UberCab.com, built a prototype, and recruited Kalanick to help run it.

The first version launched in San Francisco in 2010 as a black car service — not the cheap rideshare everyone knows today. You'd tap a button, a Lincoln Town Car would show up, and it cost about 1.5x a regular taxi.

Ryan Graves answered a tweet from Kalanick looking for an "entrepreneurial product manager" and became employee number one. He ran operations while Kalanick was still finishing up another startup.

Graves would later become CEO briefly before handing the reins to Kalanick. The app launched with just a handful of cars in San Francisco.

It worked so well that riders couldn't shut up about it.

The real inflection point came in 2012 when they launched UberX — regular people driving their own cars at prices cheaper than taxis. That one decision turned Uber from a luxury black car service into a verb.

Within two years, UberX was available in hundreds of cities and the word "Uber" had entered the dictionary.

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.

Uber

Uber's early growth strategy was beautifully ruthless. They'd roll into a new city, launch without asking permission, and deal with the regulatory fallout later.

They called it "Travis's Law" — it's easier to ask forgiveness than permission.

The playbook was simple: launch in a new city, give massive discounts to riders (sometimes completely free rides), pay drivers signing bonuses and guaranteed hourly rates, and flood the zone until the city was hooked. Then slowly raise prices and cut driver incentives once the market was locked.

They burned billions doing this but it worked — by 2016 Uber was in 500+ cities across 70 countries.

They also weaponized word of mouth with referral codes. Every rider could give free rides to friends.

Every new driver got a bonus for signing up. The viral loop was insane.

At peak growth, Uber was adding a new city every day.

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.

Uber

Where do you even start? Uber might have faced more simultaneous existential crises than any company in history.

Regulatory wars. Taxi unions, city governments, and entire countries tried to shut Uber down.

London revoked their license. France arrested two executives.

Uber was banned, unbanned, re-banned, and sued in dozens of jurisdictions simultaneously.

The toxic culture. In 2017, former engineer Susan Fowler published a blog post describing rampant sexual harassment, discrimination, and HR cover-ups at Uber.

It went nuclear. Investigation after investigation followed.

Board members resigned. Executives were fired.

Travis Kalanick's ouster. After the culture scandals, a leaked video of him berating an Uber driver, and a federal investigation into stolen trade secrets from Google's self-driving car unit Waymo, the board forced Kalanick to resign as CEO in June 2017.

Dara Khosrowshahi came in from Expedia to clean things up.

The cash burn was legendary. Uber lost $8.5 billion in 2019 alone.

They subsidized rides so heavily that riders were paying less than the actual cost of the trip. The company didn't turn its first operating profit until Q3 2023 — fourteen years after founding.

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.

Uber

Uber Rides is the core product — get from A to B in someone else's car. UberX is the standard option, Uber Black is the premium black car tier, UberXL fits bigger groups, and Uber Reserve lets you schedule rides in advance.

Uber Eats is the food delivery arm and competes directly with DoorDash and Grubhub. Uber Freight is the logistics play — basically Uber for semi-trucks, connecting carriers with shippers.

Uber for Business lets companies manage employee rides and meals. Uber now also offers package delivery, grocery delivery, and even boat rides in some cities.

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.
