This week we take on the question of whether we are on the cusp of a retail disruptor apocalypse, with the help of return guest Daniel McCarthy, Assistant Professor of Marketing at Emory University's Goizueta School of Business and leading expert on customer-based corporate valuation.Before Dan joins us we briefly review the similarities between the first wave of online brands that subsequently melted down (remember Pets.com?) and what we've seen with the latest crop of digitally native brands (Warby Parker, Allibirds, Stitch Fix, TheRealReal, et al ) that have seen their valuations collapse and continue to struggle to get on a glide path to profitability. Then Dan joins us to help dissect the underlying (and often challenging) unit economics of these fast growing brands, with a particular focus on Wayfair and Warby Parker. In addition to helping us understand how to better understand the relationship between customer acquisition costs and lifetime value, we learn about "CACulations" and the dangers of "spending up the wazoo."But we open with a review of the biggest news of the week, which revealed that the holiday season was not so merry and bright when it came to actually making much money. Target shared some curbside enthusiasm, while delivering pretty tepid results. Best Buy and Macy's lost ground, while warning about a difficult road ahead. Kohl's was exactly the train wreck we've been predicting. We wrap up with hot takes on Nordstrom bailing on Canada, Hanna Andersen's cleverly named resale entry, and Walmart's doubling down on same day delivery.We're headed to Las Vegas in March for another edition of Shoptalk.
