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.

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.

Yelp

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.

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.

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.

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.

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.

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.

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.
