Tim Cook

Cook is on this list twice over. He succeeded Steve Jobs in 2011, after running the company during Jobs's medical leaves, and Apple's revenue and value grew many times over on his watch through services, wearables and supply-chain discipline. Then, after what the board called a long-term succession process, he handed the chief executive role to hardware chief John Ternus on 1 September 2026 and became executive chairman. The second handover is too recent to judge.
