The Acceleration of Unicorn Startups

CB Insights just made this great infographic to help visualize the rate at which new billion dollar unicorn companies are being created. It seems to be as increasing trend since the start of 2014. There are now 142 total unicorn companies with a total cumulative valuation of $506B. This is up from 30 privately held technology companies worth more than $1B about 18 months ago.

Last month Mark Suster wrote on how he believes this trend is being driven by a fundamental change in the the structure of the Venture Capital industry and how money is entering the market. Let me know what you think is driving this change in the comments.
