What are the critical abilities of successful startup founders?

If we leave only one essential ability that all company founders should possess, it is that of an activator. Activators find a way to initiate something and achieve results, which is synonymous with the notion of a leader. Activators create the team's core, develop the basic "idea" and strategic direction, organize the legal form, find office space, organize meetings, etc. What else can you add, hunters?
