The terms “valuation” and “unicorn” are major buzz words in the venture community. Everyone wants to know how much a company is worth, if it’s a unicorn and even how fast it got to that point. We recently dug into the PitchBook Platform to find the 20 companies to reach a $2 billion private valuation the fastest—it was a big hit. But how much does that really say about a company’s success? Josh Burwick, managing partner at Sand Hill East, recently wrote in a blog post: “Just because a bunch of smart investors say a company is worth a certain valuation and invest money with that underlying assumption, does not make it a reality.” With this idea in mind, we compiled a new list of top companies—those that have reached a $1 billion+ exit the fastest.
