Zillow has laid off 500 employees—about 7% of the portal’s 7,000 employees—in order to ensure a “disciplined cost structure” across the portal, according to an announcement by CEO Jeremy Wacksman today. A Zillow spokesperson referred to the blog post, but did not respond to specific RISMedia inquiries related to the layoffs. Wacksman said in the post that Zillow has been seeing strong growth and “outperform(ing) the category, despite a housing market that has been essentially flat.” “These changes are about ensuring we have a disciplined cost structure and getting more efficient, with the right people in the right positions,” he said. This is the portal’s second round of layoffs this year, originally laying off 200 employees back in January.
