What should be the relationship between the CEO and the team's employees [COMPANY CULTURE SETTING]

What I like about tech culture or marketing is that it tends to be more relaxed. At least in my experience, I’ve always had a very open and friendly relationship with CEOs.

But the bigger the company, the more “distant” the CEO tends to be from the team members.

(For example, it’s much easier to remember everyone’s name in a flat structure with 14 people than in a large corporation where a manager manages a manager who manages someone else and has dozens of people under them. You get me.)

How do you "nurture" and "raise" your company culture?

Do you prefer a formal or an informal – friendly – approach?

(And if you lean towards an informal approach, how does a manager build authority within their team?)

Would love to hear your approach and reasoning.
