Burn, baby, burn. This is exactly what UK-based Boo.com did in the late 90s, when it burned through more than $135 million. Boo billed itself as an online fashion store in 1998, and was backed by investment banks JP Morgan and Goldman Sachs. The site was founded to become a digital center for the cool and chic, and Fortune called Boo one of Europe's coolest companies before it even launched. With so much potential, the founders aimed high, hoping to sell its items in about 18 countries. But back then, the Internet was still young, and only about 20 percent of people were online in the UK. The company built too much, too soon, and couldn't sustain itself when people didn't flock to the site. It closed two years later in 2000.
