Zillow was founded in 2005 by Rich Barton and Lloyd Frink. The two were former Microsoft executives and co-founders of Expedia. The website is an online real estate database where buyers and sellers can research properties and their values by using the company’s Zestimate.
In 2008, Zillow Mortgage Marketplace and Zillow Advice were launched. The marketplace allows home buyers to get loan quotes without entering personal information like social security number. The Advice portion of the site allows people to ask real estate questions and get answers from local experts in their market.
In 2009, the company partnered with over 180 US newspapers to offer real estate search engines to their websites. Zillow Mobile was also launched this year.
Zillow went public in 2011. They also acquired Postlets and partnered with Yahoo Real Estate.
Today, Zillow and Trulia are the leading real estate websites in the world.
