Casper
DTC mattress unicorn IPO'd at $575M in 2020 after raising $339M—then was taken private in 2022 at $6.90/share, down 79% from its IPO price, after years of losses proved the model unworkable.
Evaluating only Casper’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. That’s exactly how it died.

Documented cause
Casper was founded in 2014 to disrupt the mattress industry with a DTC model: one mattress, shipped compressed in a box, sold online with a 100-night trial. The company raised $339M from investors including Target, Lerer Hippeau, and New Enterprise Associates, and IPO'd in February 2020 at $6/share implying a ~$575M market cap. Despite strong brand recognition, Casper consistently lost money: customer acquisition costs for mattresses (a low-frequency purchase) were high, physical retail stores proved necessary for consideration-intensive purchases, and competition from Tuft & Needle, Purple, and traditional retailers intensified. The company was taken private by Durational Capital Management in November 2022 for $6.90/share—23% above its depressed share price but 79% below IPO price. Physical stores were closed; brand was sold.
Lesson
“DTC businesses for high-consideration physical products must achieve customer acquisition cost < 20% of first purchase gross margin. For mattresses with a $1,000 ASP and 40% gross margin, maximum CAC is $80. If that is not achievable through digital channels alone in your first 100,000 customers, your DTC thesis does not work at scale.”
