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.

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.

Business listings and reviews — 265+ million reviews across every local business category. Yelp for Restaurants — reservations, waitlist management, and ordering integrated into business pages.

Yelp Ads — advertising platform letting businesses target users by category, location, and intent. Yelp for Business Owners — dashboard for responding to reviews, tracking page views, and managing business info.

Yelp Elite Squad — gamified community of prolific reviewers who get invited to exclusive events. Yelp Guest Manager — restaurant management tool combining waitlist, reservations, and table management.

Yelp Knowledge Program — data licensing to power local search across third-party platforms.

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.

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.

Pre-IPO investors included Bessemer Venture Partners, Max Levchin, and Peter Thiel's Founders Fund. Yelp went public on the NYSE in March 2012.
