Zillow + Trulia (with Zillow Group CFO Kathleen Philips)

The episode opens with a production note about rough audio and a request to listen on speakers rather than headphones, then introduces the guest: Kathleen Phillips, CFO of Zillow Group, formerly its COO and general counsel, and the person who ran corporate development for her entire six years at the company, with prior legal and operating roles at StubHub and Hotwire. Gilbert frames the format deliberately — Rosenthal leads the acquisition history and conducts it as a conversation rather than a monologue — and Rosenthal states the show's standing preference for public-company deals and litigation, because the SEC filings put the negotiation on the record. In this case, only the filings are needed.

Rosenthal's compressed history is precise about lineage. Zillow was founded in 2005 by Richard Barton and Lloyd Frink, who had worked together at Microsoft and then founded Expedia in 1996 — inside Microsoft, spun out, and public by 2001 — before leaving to start Zillow. Trulia came a year earlier, in 2004, founded in the Bay Area by Pete Flint and Sami Inkinen, Stanford MBA students who, according to the founding legend, were struggling to find housing for their second year in Palo Alto and concluded there had to be a better way.

The product insight that made Zillow a brand was the Zestimate: a data-driven estimate of what every home in the database would be worth on the market, built from many inputs but especially comparable sales nearby. Rosenthal's claim about why it mattered is the important part — it was, he believes, the first time US homeowners had any indication of their house's value without listing it. The private company raised roughly $80 million in venture capital, including from Benchmark.

The acquisition story begins before Trulia's IPO: per the eventual SEC filings, Zillow approached Trulia about a deal in late 2011, after Zillow's own offering but before Trulia's. Phillips confirms the timing from the inside — she joined in July 2010, about a year before the IPO completed, and spent that year entirely on getting the offering done.

Her explanation of motive is the most useful correction in the segment. The approach was not a strategy of waiting for strength; it was a consequence of having liquid public currency, which she says was one of the primary reasons they concluded the IPO at all. The acquisition timeline supports it: one small deal before July 2011, then a liquid publicly traded stock that gave them the flexibility to pursue more, with Trulia the natural first choice.

Rosenthal generalizes from his venture experience: private-to-private merger talks stall on valuation precisely because neither side's stock has a price. Phillips agrees and adds a second complication — an acquisition of that scale followed by an IPO would have required constructing a story far more complicated than simply knowing your own business and telling it well to the street. Rosenthal adds the disclosure asymmetry: public companies' financials are visible, private ones' are not.

The 2011 round ends with Trulia hiring Catalyst as adviser and the talks breaking down in early 2012; by August 2012, with Trulia preparing its own IPO, Zillow approaches a second time. Phillips says they knew Trulia was heading public and expected it, because Zillow had forged the path and Trulia had a very similar story. Asked whether they ever considered waiting for Trulia's IPO to validate the category for investors, she is blunt: they never thought about it in those terms, because Zillow was always the much larger player and was charting its own course.
