I ran Opendoor's pricing unit for the years leading up to IPO. I can say that this designer has a fundamental misunderstanding of the housing market and the Seller mindset which is likely why leadership ignored him.

In housing, EVERY OWNER BELIEVES THEIR HOME IS WORTH MORE THAN IT IS, and will be offended by a fair offer. Period. The failure of their lead designer to realize this after all these years is just one signal into why Zillow couldn't succeed where Opendoor did.
