Went public: March 2000

Webvan was a perfect example of great concept, horrendous execution. The online grocery business promised customer deliveries within 30 minutes (or less) and expanded across 10 markets in its first 18 months. That helped the company raise $365 million for its IPO with shares peaking at $34. But a focus on infrastructure growth rather than profit margins caused Webvan to implode, falling to six cents a share and closing shop in 2001.
