Rich Barton did for real estate what he did for travel with Expedia — took an opaque industry controlled by middlemen and made the data free for everyone. Zillow gets 200 million visitors a month. The Zestimate became so influential that homeowners check it more often than they check their blood pressure. Then Zillow got cocky and decided it could flip houses using algorithms. It lost $881 million in one quarter. Turns out, having all the data does not mean you can predict the future. The iBuying catastrophe was a $1.8 billion lesson in humility. Zillow went back to what works: selling ads to realtors. Smart.

Rich Barton (who also founded Expedia and co-founded Glassdoor) and Lloyd Frink (former Expedia executive) founded Zillow in 2006. The idea: make real estate data transparent.
Before Zillow, finding home values required asking a real estate agent. Zillow put estimated home values (Zestimates) online for free.
The site exploded in popularity — 1 million unique visitors within the first three days of launch. They went public in 2011.
Acquired Trulia for $2.5 billion in 2015, dominating online real estate search.
WHAT THEY ACTUALLY DO
Zillow makes money from Premier Agent advertising — real estate agents pay to appear on property listings. This is a billion-dollar-plus business.
The company also owns Trulia, StreetEasy, and HotPads. Zillow became the default place Americans check home values (the "Zestimate").
They tried iBuying (Zillow Offers) — buying and flipping houses algorithmically — and lost $881 million in a single quarter before shutting it down. The advertising model prints money.
The iBuying experiment was a disaster.
THE PRODUCTS
Zillow (home search and Zestimate), Trulia (home search), StreetEasy (NYC rentals), HotPads (rental search), Zillow Home Loans (mortgage), ShowingTime (scheduling platform for agents)
HOW THEY GREW
Dominate the real estate search experience and monetize through agent advertising. Zillow has over 200 million unique monthly visitors.
The strategy is to be so essential to home buyers that agents must advertise on the platform. Zillow also expanded into mortgage (Zillow Home Loans) and rentals.
The company is building an integrated real estate transaction platform — search, financing, and closing in one place.
THE HARD PART
The iBuying catastrophe. In 2018, Zillow launched Zillow Offers — an algorithm-driven home flipping business.
The idea was to use data advantages to buy homes at fair prices and sell them quickly for a profit. By Q3 2021, the algorithm was overpaying for homes in a rapidly shifting market.
Zillow lost $881 million in a single quarter and shut down Zillow Offers entirely, laying off 2,000 employees (25% of staff). The lesson: having the most real estate data in the world does not mean you can predict home prices.
