Every week this year, another startup has reached a billion-dollar valuation. (Whether these private market valuations actually hold water is another question.)
We've decided to rack up a bunch of these billion-dollar startups — Cowboy Ventures' Aileen Lee first referred to them as "unicorns" — that didn't exist five years ago, and that are now valued at $1 billion or more.
For the purposes of this list, we zeroed in on U.S.-based companies that were founded in 2011 or later (since we're nearing the very end of 2015), and that are private tech companies.
We then ranked them from least to most valuable.
Valuation: $1 billion
Education startup
Udacity wants to help you "be in demand." Sebastian Thrun, also known for
launching Google's secretive hardware lab Google X, founded the company in 2011 with the lofty goal of democratizing education.
The idea is that anyone who completes one of udacity's nine nanodegrees — which include front-end web developer, Android developer, and data analyst — will be perfectly primed to get a job, since big companies actually helped design the curriculum. Over 10,000 students from 168 countries have enrolled in the nanodegree program, and in November the company raised a $105 million Series D round to continue scaling that growth.
