unicorn

unicorn — A privately held startup company valued at $1 billion or more.

In simple English

In startup language, a unicorn is a privately owned company valued at one billion US dollars or more. Investor Aileen Lee popularized the word in 2013 because such companies were rare, like the mythical animal. You may also hear decacorn, which means a private company valued at ten billion dollars or more. Valuation is what investors think the company is worth in its latest funding round. It is not cash in the bank, and many unicorns lose money. People also use unicorn for a rare person. A unicorn engineer is excellent at many different skills, and a job ad that asks for a unicorn is often a warning sign because the requirements are unrealistic. The context shows which meaning is used.

Real examples(4)

  • in a news discussion

    "The startup became a unicorn after its latest funding round valued it at 1.2 billion dollars."

  • in a job interview

    "I'm looking for a company that's growing fast, maybe a unicorn, but with a clear path to profit."

More mistakes(2)

Handle with care. Do not confuse with the mythical creature. In tech business, it refers specifically to a privately held startup valued at $1 billion or more, not just any successful company.

  • ✕This small tech business is a unicorn because it is doing well.
    ✓This startup achieved unicorn status with a $1 billion valuation.

    Being successful or profitable does not make a company a unicorn—it must specifically reach a $1 billion private valuation.

  • ✕After the IPO, the company is no longer a unicorn.
    ✓After the IPO, the company is no longer considered a unicorn (it becomes a public company).

    While technically true, the term unicorn typically applies to private companies, so the phrasing should clarify the status change.
