# Zillow

**Role: failure case of overreach within [[concept-focused-differentiation]].** In 2021, Zillow tried to scale its AI-derived **'Zestimate'** pricing model into a home-flipping business (**Zillow Offers**). The AI valuations were off by up to **6.9%** for off-market listings. Zillow bought **27,000 homes but sold only 17,000**, resulting in a **$304 million write-down**, **2,000 layoffs**, and cancellation of the business — a warning against scaling an AI model beyond the firm's operational control or data reliability.
