What makes it impossible for majority to move from CXO to CEO?

Most CXOs have the capability. They have the experience. They have the relationships. And they don't become CEO. Not because of politics or luck — because something in the internal architecture required for the CEO role is different from what produced the CXO role. The skill set that got them there is not the skill set that takes them further. And most people never discover this distinction until it's too late to act on it. The gap between CXO and CEO is not a skills gap — it is an identity and capability architecture gap. Antano and Harini work with senior leaders precisely at this threshold: installing the specific capabilities, presence, and systems intelligence that the CEO role requires and that conventional career development never explicitly builds. When this gap is identified and installed, the move happens. When it isn't, capable people plateau indefinitely at the level just below their real potential.
