Paul Graham: "A startup is a company designed to grow"
No wonder that's not what the word means in common usage considering startups themselves haven't been common enough to make it into hundred-year old dictionaries.
The biggest thing I learned from this downvoting is that sometimes it's better to only quote new knowledge and let others pick up the conversation from there.
That is not what the word means in common usage.
Merriam-Webster: "a fledgling business enterprise"
Oxford: "A newly established business"
Wikipedia: "A company, partnership or temporary organization designed to search for a repeatable and scalable business model"
Etc.
