Why do proven leaders fail when they reach the top? Not for lack of intelligence, effort, or track record—but for blindspots the usual evaluations never catch.

In Seven Blindspots, Nathan Jenner draws on more than two decades as an enterprise operator, CEO assessor, and executive coach to identify seven recurring gaps that quietly derail leaders at the C-suite and CEO level. These gaps rarely surface in traditional interviews, resume reviews, or standard psychometrics. They emerge when leaders must set strategy, align teams, and guide an organization through uncertainty.

Combining firsthand operating experience with organizational psychology, Jenner shows how these patterns form, why past strengths become transition risks, and how to detect them before a succession decision is made. The result is a practical diagnostic framework for boards, CEOs, and talent leaders—built for the roles where the consequences matter most.
