Zillow is the most visited real estate website in the United States, serving as a comprehensive platform for home buyers, sellers, renters, and real estate professionals. Founded in 2006 by Rich Barton and Lloyd Frink, former Microsoft executives, in Seattle, Washington, Zillow has deeply integrated artificial intelligence and machine learning throughout its platform to power home valuations, search experiences, and market insights. Zillow's most prominent AI feature is the Zestimate, a proprietary automated valuation model that uses machine learning to estimate the market value of over 100 million homes across the United States. The Zestimate analyzes hundreds of data points including physical attributes, tax assessments, prior sale prices, comparable sales, location data, and market conditions to generate home value estimates that are continuously updated as new data becomes available. Zillow has invested heavily in improving the Zestimate's accuracy, reducing its median error rate significantly over the years through advances in neural network architectures and data processing. Beyond valuations, Zillow uses AI to power personalized home search recommendations that learn from user behavior, preferences, and search history to surface the most relevant listings. The platform's natural language search capabilities allow users to describe what they are looking for in conversational terms. Zillow's AI also powers its rental platform, Zillow Rentals, which uses similar machine learning approaches to estimate rental prices and match renters with suitable properties. The platform offers tools for real estate agents including Premier Agent, a paid advertising program, and Zillow Showcase, an enhanced listing product. Zillow provides its services free to consumers, generating revenue primarily through advertising, Premier Agent subscriptions, and mortgage origination through Zillow Home Loans. Agent advertising packages vary by market and are priced on a cost-per-lead or subscription basis.
