// WHY EACH FAILED

🔥 Pets.com
Unit Economics
Pets.com spent $11.8M on Super Bowl advertising in 2000 before achieving product-market fit. The company shipped heavy, low-margin pet food at a loss — spending $1.20 to deliver $1 of product. It went public in February 2000 and shut down in November 2000 — nine months after IPO.
// LESSON
Advertising budget is not a substitute for unit economics. You can spend your way to awareness. You cannot spend your way to profitability when the fundamental economics are negative.
🔥 Debenhams
Competition
Debenhams entered administration in April 2019, was rescued, entered administration again in December 2020, and closed all 166 stores in May 2021. A combination of online retail competition, £600M in private equity debt loading, and COVID-19 lockdowns destroyed the business over a decade.
// LESSON
Private equity debt loading on a structurally declining business accelerates the inevitable. Debt amplifies both upside and downside. On the way down, it is a death sentence.
