The mattress-in-a-box brand that defined DTC hype cycle - explosive growth, massive funding, troubled IPO, cautionary tale.
Launch (April 2014)
Five founders (Philip Krim, Neil Parikh, T. Luke Sherwin, Jeff Chapin, Gabe Flateman) shipped compressed mattresses in boxes, delivered via UPS. $500-$850 price vs $2,000+ retail. 100-night trial, free returns. Sold $1M first month.
VC Darling
Raised $239.6M total:
- Leonardo DiCaprio investor (2015)
- $100M Series C (June 2017) at $750M valuation
- Peak valuation: $1.1B (2019)
Marketing Blitz
Subway ads everywhere (NYC takeover 2015), podcast sponsorships (Serial, Gimlet shows), influencer unboxings. “The perfect mattress” narrative - one model fits all vs confusing showroom options.
Competitive Hellscape
Casper’s success spawned 175+ mattress startups by 2018: Purple, Leesa, Tuft & Needle, Nectar, Saatva, Helix, Layla. Market saturated, customer acquisition costs soared. “Mattress wars” - companies sued each other over reviews.
IPO Disaster (February 2020)
Filed to raise $200M, dropped to $100M. Priced at $12 (below $15-$17 range). Stock opened at $12.03, fell to $9 within weeks. Had never been profitable. COVID initially boosted sales, but long-term struggles continued.
Acquisition (2021)
Acquired by Durational Capital Management for $286M (November 2021) - less than Series C alone. Taken private, delisted from NYSE. Humiliating end for unicorn.
Cautionary Tale
Became symbol of DTC excess: VC-subsidized customer acquisition, ignoring profitability, me-too competition, retail eventually necessary (Casper opened stores 2018).
