Full Analysis
Stitch Fix combined AI algorithms with human stylists to send personalized clothing boxes to subscribers. The company IPO'd at $2.3B in 2017. But the hybrid model was expensive — human stylists were needed because AI alone couldn't understand fashion preferences. Revenue peaked at $2.1B then declined as customers churned. The stock fell 96% from its peak. While technically still operating, Stitch Fix has laid off half its workforce and is a shadow of its former self.
