Casper sold mattresses online, made the category feel modern, and became one of the best-known DTC brands of its decade. When it filed to go public in January 2020, the registration statement laid out its economics in more detail than most brands ever share. They’re worth reading as a lesson in what a product’s replacement cycle does to everything else.

FiledCasper Sleep Inc., Form S-1 (January 2020) for 2017 and 2018; full-year 2019 results released March 19, 2020. Shares of revenue are my arithmetic Derived.

Revenue grew about 75% in two years. Losses grew with it. Sales and marketing spending never fell below 35 cents of every dollar of revenue.

The clock in the product

The registration statement put the core problem in one line: the traditional replacement cycle of many of its products was “longer than Casper’s existence” Filed. A mattress is bought once in many years. That means almost every sale has to come from a new customer, and every new customer has to be bought.

Casper knew this and built around it. The filing describes a “Sleep Economy” worth hundreds of billions of dollars, and a product line that reached into pillows, sheets and bedding. It reported that more than 16% of its direct customers had come back to buy again Filed. For a mattress company that’s a real achievement. For a business spending more than a third of revenue on marketing, it wasn’t enough. Casper also described its e-commerce economics as “first purchase profitable,” by its own definition, and still lost $93 million in 2019. Whatever the first order covered, it didn’t cover the rest of the business.

When the product’s clock is measured in years, the first order has to pay for itself. Nothing after it arrives soon enough.

What happened

Casper priced its IPO on February 5, 2020 at $12 a share Filed, after cutting the expected range from $17–19 Reported. The pricing valued it at roughly $575 million, against a $1.1 billion valuation in its last private round Reported. In November 2021 it agreed to be taken private by Durational Capital at $6.90 a share, and the deal closed in January 2022 Filed. The brand was later sold on to Carpenter Co. Reported.

It would be easy to tell this as a story about bad marketing. It isn’t. Casper’s marketing was famous for being good. The lesson is about fit between the growth model and the product’s clock. A consumable reordered monthly can afford to lose money on the first order, because payback comes in weeks. A product replaced once a decade can’t, because payback may never come from that customer at all.

Where your product sits

Do this

• Write down your product’s clock, the typical time between purchases for a customer who does come back. If it’s longer than your payback ceiling from chapter 4, your first order has to pay for acquisition, and your offer and media targets should say so.
