Zillow

Zillow makes money by charging real estate agents to show their faces and contact info next to home listings. They give people a free, fun way to peek inside every house for sale in their neighborhood. They won by being the first site to put a “price tag” (Zestimate) on every house in America. Their secret is that they have more people looking at homes than anyone else, so agents must pay them just to be seen. They use Data Leverage to run a Brokerage model distributed through a website.
