unicorn
The valuations that lead to startup companies becoming unicorns, decacorns and hectocorns depend on their growth opportunities and expected development.
It is difficult to say for certain if we will see more hectocorns in the years to come.
Even rarer than the unicorn is the decacorn, or a start-up valued over $10 billion, and a hectocorn, valued over $100 billion.
Four unicorns were born per year in the last decade, with Facebook being a breakout hectocorn.
