# The 5x CEO

**The 5x CEO** is a book by [[entity-samantha-allison]] and [[entity-taavo-godtfredsen]], based on a **two-year research study** involving **more than 75 in-depth interviews** with private equity-backed CEOs and investors. The HBR article in this vault summarizes that research program (with coauthor [[entity-nada-hashmi]]).

The book codifies the [[framework-5x-ceo-disciplines]], the [[concept-system-of-enforcement]] thesis, and the [[concept-super-performer-cohort]] finding (53 CEOs averaging a 6.2x MOIC — see [[claim-super-performer-moic]]).

**entityType:** other (publication/book). **Enrichment:** canonical reference is the publisher or dedicated book landing page, typically linked from the authors' LinkedIn bios or from [[entity-advantageceo]].
