Root Causes
Pets.com became the poster child of dot-com excess. The company sold pet supplies online, spending $11.8M on a Super Bowl ad while generating just $619K in revenue that quarter. The fundamental problem: shipping 40-pound bags of dog food cost more than customers paid. For every dollar of revenue, Pets.com spent $1.31 on shipping alone. The famous sock puppet mascot became more valuable than the business itself. The company went from IPO to liquidation in 268 days.
