Your broader point may stand but that’s not a counter argument if you give the original claim the benefit of the doubt: it can reasonably be interpreted as referencing lifestyle oriented businesses, niche b2b companies, anything small growth with a low ceiling.

Counting unicorns only serves to bolster that point : those are large VC fueled ships which operate on a completely different level. Because it is clear at founding time which type of company they are , it’s reasonable to include that as a qualifier.

Now if the data showed more small-growth companies were started , that’d be a stronger counter argument.
