Yelp

Local advertising. Yelp is free for consumers and free for businesses to claim their listing.

Revenue comes from selling advertising products to local businesses — sponsored listings that appear at the top of search results, enhanced profiles with photos and call-to-action buttons, and Yelp Ads that target users searching for relevant businesses. Approximately 95% of revenue comes from local advertising, making Yelp essentially an ad platform for small businesses.

The company also earns from Yelp Reservations, Yelp Waitlist, and transaction-based fees on food orders. Revenue is recurring — businesses pay monthly for advertising packages — but churn is high because small businesses often cancel when they don't see immediate ROI.

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.

Jeremy Stoppelman got sick after eating at a restaurant and wanted to find a doctor recommendation online. There was nothing useful.

He and Russel Simmons — both former PayPal employees — started Yelp in 2004, originally as an email-based referral system where you'd email friends asking for recommendations. That didn't work.

But they noticed that the reviews people wrote as part of the referral process were the actual valuable content. They pivoted to a review platform where anyone could write reviews of local businesses — restaurants, dentists, plumbers, mechanics, anything.

The social element was key: reviewers had profiles, could be friends, and the best reviewers became "Yelp Elite" with status and perks. By 2008, Yelp had turned reviewing restaurants into a hobby, a social activity, and for some people, an identity.

Google reportedly offered $500 million to acquire Yelp in 2009. Stoppelman turned it down and took the company public in 2012.

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.

Yelp

User-generated content created a flywheel: more reviews attracted more consumers, which attracted more businesses, which attracted more reviewers. Yelp Elite Squad gamified reviewing, turning prolific reviewers into evangelists who hosted events and recruited new users.

SEO dominance — Yelp pages rank highly on Google for local business searches, driving organic traffic that costs nothing to acquire. City-by-city launch strategy with community managers in each market building local reviewer communities.

Advertising sales team calling local businesses directly — a labor-intensive but effective model for monetizing the platform. Mobile app became critical as smartphones made "find a restaurant near me" a constant use case.

Expansion into services (plumbers, contractors, mechanics) beyond restaurants to increase addressable market.

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.

Yelp

Google is the existential threat. Google Maps reviews have overtaken Yelp in volume and are embedded directly in search results, intercepting users before they ever reach Yelp.

Stock performance has been mediocre — shares are roughly flat over the past five years while the broader market doubled. The business model depends on selling advertising to small businesses, which are notoriously difficult and expensive to sell to (high churn, small budgets, skeptical owners).

Yelp has been accused of manipulating reviews to pressure businesses into advertising — allegations the company denies but which have damaged its reputation. Review fraud (fake positive reviews, competitor sabotage reviews) is a constant battle.

And the broader shift to social media for recommendations (Instagram, TikTok, Reddit) is eroding Yelp's relevance with younger users.

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.
