This is our Wednesday episode when we niche down to a single topic, looking to expand our understanding of one particular technology trend or another. This week? iBuying.Zillow made a decision to get out of the iBuying market, with huge costs hanging over its head and a grip of layoffs to manage. Natasha and Alex were curious what went wrong.So we brought along Ryan Lawler, one of TechCrunch+'s reporting team, who has covered the space for a chat. Ryan helped us use Opendoor earnings as a comparison point -- it turns out that the iBuying model can work, even if Zillow itself struggled with the model. (Opendoor went public via a SPAC, recall.)We also talked about what the situation could mean for startups in the real estate market more broadly. It turns out that merely having data is not enough to make money in the housing space.Equity is back Friday morning with our weekly news roundup, and if all goes well, also back on Saturday with something both special and fun.And if you haven't given our sister podcast, Found, a listen, check it out!
