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.

Instacart

Instacart operates as a marketplace connecting consumers with personal shoppers and grocery retailers. Revenue comes from multiple streams: delivery fees and service fees charged to consumers (typically $3.99+ per delivery), tips to shoppers (passed through, not revenue), retailer partnerships (grocers pay Instacart for access to the platform and fulfillment services), and advertising.

Advertising has become the crown jewel. Instacart Ads lets consumer packaged goods (CPG) brands like Coca-Cola, Procter & Gamble, and Nestlé pay for sponsored product placements within the Instacart shopping experience.

When someone searches for "chips," Doritos can pay to appear first. This is incredibly valuable because it's advertising at the exact moment of purchase intent.

Ad revenue was $871 million in 2023 and crossed $950 million in 2024.

The retailer partnership model is key. Unlike DoorDash or Uber Eats (which listed restaurants without permission early on), Instacart works with grocers as partners.

Over 1,500 retail banners including Costco, Kroger, Albertsons, and Publix have formal partnerships. Instacart provides the technology and shoppers.

Grocers provide inventory and stores.

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.

Apoorva Mehta was a 26-year-old Amazon engineer in Seattle who quit his job in 2012 to start a company. The only problem: he had no idea what to build.

Over the next year, he started and abandoned roughly 20 different projects. A social network for lawyers.

A way to track restaurant wait times. Nothing stuck.

Then one day he was too lazy to go grocery shopping. He looked for a service that would shop for him and deliver everything to his door.

Nothing good existed. The existing options were grocery store delivery services that only worked during specific windows, had limited selection, and required ordering days in advance.

Mehta wanted to order groceries the way he ordered everything else online — immediately, from whatever store he wanted.

He built a prototype in 2012 and applied to Y Combinator. The demo was rough — he ordered a six-pack of beer through the app and had it delivered to a YC partner's house during the application process.

It worked. He got in.

Instacart launched in the San Francisco Bay Area in 2013 with a simple promise: order from your favorite local grocery store and have someone shop for you and deliver within an hour.

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.

Instacart

Instacart grew by solving a problem one city at a time. They launched in San Francisco, proved the model, then expanded to other major metros.

Each new market required recruiting shoppers, signing up retailers, and building enough consumer density to make the economics work.

The COVID-19 pandemic was the inflection point. Grocery delivery went from luxury to necessity overnight.

In March 2020 Instacart announced it would add 300,000 shoppers, then raised that by another 250,000 weeks later. Order volume increased 500%.

Years of planned growth happened in weeks. The pandemic proved that grocery delivery wasn't a niche — it was the future of how a significant chunk of the population would shop.

The enterprise play is the long-term moat. By providing white-label technology to grocers, Instacart becomes embedded in their operations.

Even if a grocery chain wanted to build its own delivery service, they'd need years and hundreds of millions to replicate what Instacart provides. The more deeply integrated Instacart becomes in grocery operations, the harder it is to rip out.

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.

Instacart

The post-COVID hangover was brutal. After pandemic demand normalized, growth slowed dramatically.

The company's valuation dropped from a peak of $39 billion in early 2021 to about $10 billion at IPO in September 2023. Investors who bought at the peak saw a 75% paper loss.

The narrative shifted from "essential infrastructure" to "nice-to-have luxury."

Unit economics are perpetually tight. Paying a person to walk through a grocery store, pick items, bag them, and drive them to someone's house is expensive.

Unlike meal delivery (one restaurant, one bag), grocery delivery involves dozens of items per order, refrigeration requirements, and substitution decisions. Every order that requires a shopper to call the customer about an out-of-stock item eats into efficiency.

Amazon is the existential threat. Amazon Fresh, Whole Foods delivery, and Amazon's own logistics network represent a competitor with nearly unlimited resources and a Prime membership base of 200+ million.

Amazon has been willing to lose billions on grocery delivery to build market share. Instacart's advantage is retailer partnerships — Kroger and Publix use Instacart specifically because they don't want to help Amazon dominate grocery.
