It wasn’t long ago that the idea of a pre-IPO tech startup with a $1 billion market value was a fantasy. Google was never worth $1 billion as a private company. Neither was Amazon nor any other alumnus of the original dotcom class.
Today the technology industry is crowded with billion-dollar startups. When Cowboy Ventures founder Aileen Lee coined the term unicorn as a label for such corporate creatures in a November 2013 TechCrunch blog post, just 39 of the past decade’s VC-backed U.S. software startups had topped the $1 billion valuation mark. Now, casting a wider net, Fortune counts more than 80 startups that have been valued at $1 billion or more by venture capitalists (full list here). And given that these companies are privately held, a few are sure to have escaped our detection. The rise of the unicorn has occurred rapidly and without much warning, and it’s starting to freak some people out.
