One thing that makes great leaders is to understand your value in an organization. Some founders are better suited to run an agile below 100 startups but dont have the capacity to deal with the ops complexities that come with scaling a business.

If you look closely, the successful founder CEOs had a strong ops person by their side helping them scale. Understanding yourself and your weaknesses earlier on and enlisting people that would complement you is the key. Otherwise, even your passion, vision and right incentives won't help you be a great leader.
