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

In Seven Blindspots, Nathan Jenner distills decades of executive assessment into a diagnostic framework that reveals seven recurring blindspots most organizations miss. These gaps don't surface in interviews or performance reviews. They emerge when leaders must align teams, make high-stakes decisions, and carry an organization through uncertainty.

Combining boardroom experience with behavioral insight, Jenner shows how these patterns form, how they derail even high performers, and how to detect them before a succession decision is made. His system is built for boards, CEOs, and talent leaders to evaluate candidates, run succession with rigor, and develop senior talent for the most demanding roles—where the consequences truly matter.
