Well economic vs social axises for one. Start up culture is 'move fast and break things' which is more an economic right of minimal regulation and seeing them as obstacles to be worked around. Silicon valley has been pretty anti-authoritarian historically - starting with the Traitorous Eight and continuing to the job hopping. A more authoritarian ethos would be sticking with the company for life instead of leaving because you are pissed off about starting early and wearing a tie.

Fascism is 'you have to know somebody or be approved or you get the stick for being troublesome to the ruling parties'. While entrenching power in individuals who could pull up the drawbridge and go more controlled with regulatory capture it would be fair to say it is not start up culture at that point, not as a No True Scottsman sense. This is not a dodge of any hypothetical guilt. The policies and ethos may have lead to that outcome but the phases are very distinct - there is a difference between a family passing on their trade and a caste system even if the first may eventually lead to the later.
