Does a founder need to be abrasive / put company needs over employee needs for a startup to succeed?

Was reading the Steve Jobs book recently and realized he probably wasn't the easiest to work with / definitely did not create a great culture around him, especially in the early Apple years.

Remembered the movie on blackberry that I saw couple weeks ago and how it was this crazy, hard-ass ceo took charge and actually turned the company around, otherwise Blackberry would be nowhere in our memories today.

Do you think this is what is actually needed to build successful companies early on - and employee wellbeing and culture are things to be solved for later in the journey of a company?
