noun
Refers to a person who owns or runs an industrial enterprise; can also imply a business founder or capitalist.

実業家 is a more common term for 'businessperson' or 'industrialist'; 企業者 is less frequent and may sound slightly formal or dated.
Compound of 企業 (enterprise, business) and 者 (person). The exact historical derivation is uncertain, but the word follows a standard pattern for forming agent nouns.
