Steve Jobs

Steve Jobs engineered the most iconic corporate turnaround in history: returning to a bankrupt Apple in 1997 and scaling it to a $2.3 trillion valuation by 2020. His relentless product obsession yielded the iMac, iPod, iPhone, and iPad—each redefining its category. Jobs’s ability to distill complex technology into intuitive design is unmatched; even #2 Jack Welch’s Six Sigma rigor could not produce consumer products with the same cultural impact. Under Jobs, Apple’s revenue surged from $7.8 billion in 1998 to $108.2 billion by 2010, a 1,287% increase—faster than the average growth rate of any other CEO on this list. His perfectionism, while brutal, created an ecosystem that commands 50% of global smartphone profits with just 15% unit share.
