Depends on how hard you run your own business. You can't go to $1M without driving hard. The ones that got lucky (struct on once-in-a-lifetime idea) typically don't stay up at $1M that long if they continue to run it like a side-hustle doing 20 hours per week.
> Directors at FAANG have wayyyy more pressure
That pressure is pushed down to the army of EMs and SWEs (-_-"). FAANG is a body shop because they have their hiring pipeline with potential candidates; they can afford to burn bodies (hi Netflix and Amazon :D :D).
> because you can always spin another SaaS
Not to $1M level that easily within 1-2 years...
> but is very hard to get another Director position at another company once you get fired from one
I don't know... I rarely seen Dir got fired and tailspin in the career. Can always go as Senior EM and climb up again.
> Also, your kids/family can inherit your business, but not your job.
This is the only thing that might be a WIN for entrepreneurship but now you have 2 worries: 1 running the company, 2 finding your successors.
