Four out of ten executives promoted to the C-suite don't make it past 18 months. That's the number that sent Navid Nazemian down a research rabbit hole, and eventually led him to write the first book on executive transitions — Mastering Executive Transitions: The Definitive Guide.

Navid speaks with an authority that is grounded in research and complemented by authentically demonstrated experience. His coach education took him on a 3-year journey across three continents in Europe, Africa & America. Working with 250+ C-level coaching clients worldwide, he distills key insights, guidance, and coaching for maximizing leadership impact. He has been recognized as HR's Most Influential Practitioner by HR Magazine, received the Outstanding Leadership Award from Education 2.0, and been ranked as the World's #1 Executive Coach by CEO Today three years in a row.

In this episode, Navid unpacks what actually happens during those critical first 18 months in a new C-level role, why the "first 90 days" playbook is no longer enough, and what every professional — not just executives — can learn from how the top performers prepare for a transition.

We go deep on the difference between coaching, mentoring, and advisory work, why HR-style "advice-giving" is often the wrong instinct in a coaching seat, and how Navid's Double Diamond Framework helps incoming leaders avoid becoming part of the 40% statistic.

Plus — Navid shares a brand new concept, Executive Transition Intelligence (ETI), with this podcast as the first place he's ever discussed it publicly.
