Documented cause
Trunk Club built a personal styling service for men where professional stylists curated clothes sent in a trunk for try-on at home. It raised $12M and was acquired by Nordstrom in 2014 for $350M. Under Nordstrom ownership, it expanded to women and built out club locations. But Stitch Fix scaled massively with algorithmic personalization that was cheaper than human stylists, and the COVID-era closures of Trunk Club physical locations removed the personal experience that differentiated it. Nordstrom quietly shut down Trunk Club in October 2020.
Lesson
“Human-curation businesses face an algorithmic cost curve problem: as AI personalization improves, the quality gap between algorithm and human stylist narrows while the cost gap widens. Trunk Club human stylist model was differentiating in 2009-2014; by 2019, Stitch Fix algorithm was providing comparable curation at 30% of the cost.”
