Documented cause
Casper Sleep was founded in 2014 by Philip Krim, Neil Parikh, T. Luke Sherwin, Jeff Chapin, and Gabriel Flateman, disrupting the mattress industry with a direct-to-consumer model: one mattress, delivered in a box, with a 100-night trial. The concept was immediately viral and the company grew to $100M in revenue in its first year. It raised approximately $340M, counting investors from NEA to celebrities. The category it created proved its own destruction: the mattress-in-a-box format was easy to copy, and over 150 direct competitors appeared — Purple, Nectar, Saatva, Tuft & Needle — each offering similar products at lower price points. Casper's customer acquisition costs soared as every Google search for "best mattress" became a competitive war. Its February 2020 IPO priced at $12 per share (below the midpoint of its $14-16 range) at a $575M valuation. The stock never recovered the IPO price. In February 2022, Casper was taken private by Durational Capital Management at $6.90 per share — 45% below IPO price — ending its story as an independent company.
Lesson
“Creating a category proves the category is valuable to every competitor watching. The pioneer's customer acquisition cost rises every month as funded copies enter the market.”
