Where does decacorn come from?

A unicorn is a mythical horse with a single horn protruding form its head. In 2013, venture capitalist Aileen Lee wrote an article for TechCrunch where she likened new companies (startups) valued at over $1 billion to ܲԾǰԲ—famously rare in legend, just like such companies.
By 2015, suchunicornshad become more more common in the business world. So, a 2015Business Insiderarticle described companies valued at over $10 billion asdecacorns, what Lee previously dubbed “super unicorns.” The articleidentified Airbnb, Uber, and Pinterest as decacorns, among others.

While the uni– in unicorn comes from the Latin-based prefixuni- (“one”), decacorn features the prefix deca–, ultimately from the Greek word for “ten.” FYI, there are no decacorns in myth (horses with ten horns).
Companies valued at over $100 billion, like Google, Microsoft, and Amazon, are called hectocorns(hecto-, “hundred”), JSYK.
Examples of decacorn

Who uses decacorn?
The term decacorn is principally found in tech and business media and discussions. As noted, it often refers to a relatively new, tech-based startup company that is privately owned (i.e., not (yet) publicly traded).
As of 2019, the platform CB Insights valued 17 companies as decacorns with China’s ByteDance (who owns TikTok) as the “fattest” decacorn at a $75 billion evaluation. Other notable decacorns include Airbnb ($29.3 billion) andFortnite creator Epic Games ($15 billion).
