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.

Resolves the questions raised in Troverie (A); recounts pivots and efforts to raise capital from strategic investors and sell Troverie; and shares the founder's post-mortem reflections on what went wrong and what he might have done differently.

uBiome provided clinical tests that sequenced the DNA of human microbiome samples, providing data on health conditions directly to consumers or to prescribing physicians. Founded in 2012, the San Francisco-based startup raised $105 million from top-tier venture capital firms and recruited prominent biotech executives and scientists as board members and advisors. In April 2019, the FBI raided uBiome's offices to investigate claims that the company had repeatedly billed individuals without their consent to meet aggressive revenue targets. uBiome's cofounders/co-CEOs resigned soon afterward. The company declared bankruptcy later that year after a board committee concluded that management had indeed pursued policies of questionable legality, including improper insurance billing practices, improper use of a telemedicine physician network, overly aggressive marketing tactics, and the presentation of misleading information in fundraising pitches.
