Zillow Group, Inc.
A residential real estate platform that helps people buy, sell, rent, and finance homes across the U.S., anchored by its Zestimate home-value model and tools like Zillow Home Loans, Premier Agent, and ShowingTime. It was co-founded in 2006 by former Microsoft and Expedia executives Rich Barton and Lloyd Frink, who named it by blending "zillions" (the data points) and "pillow" (the personal side of home).
Estimated from filings — the split-adjusted price range over the quarters each manager built the position. A range, not a fill price; 13F reports a quarter-end snapshot, not a trade date.
