Six months after the August 2018 launch of Troverie, a U.S.-based online retailer of luxury watches, the average cost of acquiring a customer is much higher than originally projected, and the startup is incurring a substantial loss on each sales transaction. Could customer acquisition costs be reduced through optimization of marketing messages and channels, or did high marketing costs presage a fundamental problem with Troverie's business model? Troverie was an authorized retailer of 17 luxury watch brands, and had partnered with brick-and-mortar jewelry retailers that would drop ship the watches from their inventory in exchange for a share of Troveries's revenue. The brands were authorizing online sales for the first time, to combat "grey market" outlets that sold their watches without the manufacturer's warranty.
