Why startups fail
The idea graveyardE-commerce

Pets.com went from IPO to liquidation in 268 days.

The pitch — name stripped

An online store shipping commodity pet supplies — food, litter, toys — nationwide, acquiring customers through heavy brand advertising and selling below cost to win the category fast.

Kasspian’s cold read on Pets.com

3/10Don't build it

Fatal flawThat you can sell heavy, low-margin commodity goods below cost, subsidise the shipping, and still reach profitability before the cash spent acquiring each customer runs out.

What actually happened

Pets.com launched in 1998 and became the most famous casualty of the dot-com bust. Backed by Amazon among others, it sold pet supplies online and spent enormously on brand-building — most memorably a sock-puppet mascot that ran a Super Bowl ad and became a household face.

The product was a commodity: the same bags of food and litter you could buy anywhere, heavy and expensive to ship. To win customers, Pets.com sold below cost and absorbed the shipping, betting that scale would eventually flip the economics.

It never did. Every order lost money, marketing burned cash faster than revenue could replace it, and there was no structural reason a customer would stay loyal to one undifferentiated pet store over another. Growth made the losses bigger, not smaller.

The company IPO'd in February 2000 and was liquidated by November the same year — 268 days, one of the fastest public collapses in startup history. The sock puppet outlived the company.

The irony is that online pet retail became a huge, real business — Chewy proved it years later. The idea wasn't wrong. The economics and the timing were.

The lesson

Kasspian scored the stripped pitch 3/10 because the killer was hiding in plain sight in the unit economics: selling below cost with subsidised shipping on a commodity means every sale loses money, and growth multiplies the loss. No amount of brand love fixes a negative contribution margin.

The sock puppet is the cautionary detail. Pets.com had one of the most recognised mascots in America and still died, because awareness is not the same as a viable business. Marketing can manufacture demand; it cannot manufacture margin.

If you're selling a commodity, your homework is the contribution margin on a single order before any marketing — does the second sale, at full price, pay for itself? Pets.com is proof that a good market (online pet supplies really was one) is not a good business until the maths on one transaction works.
