PE Leaders' Best Business Books of 2025

Every year, the most effective private equity operators read voraciously — scanning for insights that sharpen their deal instincts, scale their portfolio companies, and, perhaps surprisingly, help them build more intentional lives outside the office. On Episode 134 of Karma School of Business, BluWave CEO Sean Mooney gathered nine PE leaders to share the books shaping their thinking right now.

"The best business builders in the world are collectors and purveyors of other people's wisdom," Mooney observed. This roundup is exactly that wisdom, distilled: 14 books from 9 operators, organized by theme, and ready for your 2025 reading list. The private equity best business books of 2025 span capital allocation classics, life design philosophies, Stoic mindset frameworks — and one infant sleep guide that earned the episode's loudest laugh.

The Operator's Edge: Strategy, Scale, and Capital Allocation

The most-cited theme among PE professionals this year was a deceptively simple question: How do the very best operators actually do it? Three books dominated this conversation.

The Outsiders — William Thorndike Jr.

Recommended by: Ran Ding

The Outsiders profiles eight CEOs who generated extraordinary long-term returns not by following conventional wisdom, but by deploying capital differently than their peers. For Ran Ding, the book crystallized a core PE truth: "These people were doing things slightly differently — really good capital allocators."

In a world where every firm claims differentiation, the book is a rigorous reminder that disciplined, contrarian capital allocation is the actual source of alpha — not operational complexity, not financial engineering, but the careful, repeatable discipline of putting money to work in the right place at the right time.

Traction — Gino Wickman

Recommended by: Dan Gaspar

Dan Gaspar calls Wickman's Entrepreneurial Operating System (EOS) the framework "that most closely matches my approach" to running portfolio companies. For PE professionals tasked with installing operational rigor in acquired businesses, Traction delivers a practical blueprint — clear accountability structures, measurable goals, and a repeatable rhythm for executing change.

EOS-based implementations are among the most common operational improvement engagements across BluWave's network, making this a particularly actionable read for anyone responsible for post-close value creation.

The Innovator's Dilemma — Clayton Christensen

Recommended by: Chris Scullin

Christensen's classic is more urgent than ever in an era of rapid technological disruption. Chris Scullin's takeaway: "Things are always changing — you have to change your tactics to maintain outcomes."

For PE-backed companies competing in dynamic markets, the book functions simultaneously as a strategic warning and a survival guide. The firms that fail, Christensen argues, are often doing everything right by conventional measures — and that's precisely the problem.

The Long Game: Designing a Life Worth Living

The second dominant theme — one that might surprise outsiders — was a preoccupation with life design beyond the balance sheet. Several PE leaders recommended books that challenged them to think more intentionally about wealth, time, and purpose.

Die With Zero — Bill Perkins

Recommended by: Steve Hunter

Bill Perkins' thesis is deliberately provocative: most high-achievers will die with far more money than they can spend, and they'll have spent the years that money could have funded working to accumulate it. For Steve Hunter, the book's core challenge landed hard: "You're going to run out of health or time — not money."

For PE professionals who've spent careers maximizing financial accumulation, Die With Zero reframes the optimization target entirely. It argues for front-loading experiences while you have the energy to enjoy them — a mindset shift that professionals who routinely defer gratification may find particularly confronting.

The Algebra of Wealth — Scott Galloway

Recommended by: Jonathan Metrick

Scott Galloway's framework pushes well beyond financial compounding. Jonathan Metrick's key question after reading: "What else are you compounding in your life, career, and time?" For PE professionals obsessed with return multiples, The Algebra of Wealth applies the same long-term compounding logic to relationships, skills, and health — the portfolio that ultimately determines life quality in ways a MOIC cannot.

From Strength to Strength and Build the Life You Want — Arthur C. Brooks (with Oprah Winfrey)

Recommended by: Casey Myers

Casey Myers recommended two Brooks titles together, and the pairing is deliberate. From Strength to Strength addresses a challenge many successful operators eventually face — "making that shift from building things to teaching things" — as fluid intelligence gives way to crystallized wisdom. Its companion, co-authored with Oprah Winfrey, takes a more practical lens: "It's okay to lean into all the different hats you could wear." Together, they form a blueprint for sustained fulfillment across a career that outlasts any single peak.

The Second Mountain — David Brooks

Recommended by: Micah Dawson

David Brooks draws a distinction that resonates with PE operators who've scaled the conventional success ladder: the first mountain is achievement; the second is service and meaning. Micah Dawson found in it a language for the transition many senior PE professionals are quietly navigating — not away from ambition, but through it toward something more durable.

The One Thing — Gary Keller & Jay Papasan

Recommended by: Micah Dawson

Also from Dawson, The One Thing confronts the hedonic treadmill directly. "The horizon constantly recedes," he observed — so the discipline of radical focus, and the practice of looking back at what you've built rather than always forward at what remains, becomes essential for sustainable motivation. In a business context defined by 100-day plans and multi-year hold periods, it's a useful corrective toward depth over breadth.

Mind Over Matter: Mindset, Resilience, and Adaptability

The third cluster of recommendations centered on the psychological toolkit that separates top PE operators from capable but plateaued ones.

The Obstacle Is the Way — Ryan Holiday

Recommended by: Ran Ding

Ryan Holiday's Stoic framework — the obstacle is the way through — resonated strongly with Ran Ding's operating philosophy: "How you react is completely within your control." In private equity, where deal timelines compress, macro conditions shift without warning, and portfolio companies hit unexpected turbulence, Stoic pragmatism isn't merely philosophy — it's infrastructure.

Who Moved My Cheese? — Spencer Johnson

Recommended by: Dan Gaspar

A deceptively simple classic, Who Moved My Cheese? carries a message Dan Gaspar calls timeless: "Embrace change. Never get complacent." Its brevity is part of its power — it's the kind of read you can hand to a newly acquired portfolio company's leadership team and have a substantive conversation the next day. It's no accident that companies across BluWave's network have used it as a shared change-management reference.

The Happiness Hypothesis — Jonathan Haidt

Recommended by: Chris Scullin

Jonathan Haidt synthesizes ancient wisdom and modern psychology into an evidence-based framework for flourishing. Chris Scullin's summary: "Science validates what human traditions enshrined for millennia." For analytically-minded PE professionals, Haidt's approach — rigorous, data-grounded, yet deeply humane — makes the case for well-being in terms that align with an investment mindset.

Beyond the Boardroom: Curated Wildcards

Not every recommendation fit a neat business category — and that's precisely the point. The most interesting picks on Episode 134 stretched beyond strategy into literature, parenting, and the full texture of a life well-lived.

The Brothers Karamazov and The Heart's Invisible Furies — Fyodor Dostoevsky & John Boyne

Recommended by: Vinay Kashyap

Vinay Kashyap went literary, recommending Dostoevsky's masterwork ("Triggers something profound and humorous — a true masterpiece") alongside John Boyne's The Heart's Invisible Furies, a novel that explores identity and belonging across an entire lifetime. His framing was refreshingly honest: "Don't force it — follow your curiosity." It's a reminder that the most expansive leaders read widely, not just purposefully.

Twelve Hours' Sleep by Twelve Weeks Old — Suzy Giordano & Suzy Abidin

Recommended by: Misha Longinov

The episode's most memorable — and most humanizing — recommendation came from Misha Longinov, who called this infant sleep training guide "game changing... a perfect, easy to digest guide for engineering sleep." The recommendation landed with laughter and, it's worth noting, resonated loudly with the room.

It's a perfect encapsulation of what this list is really about. PE leaders aren't one-dimensional capital allocators. They're parents, partners, and people working to build full lives — and they bring the same systematic, optimization-oriented mindset to everything, including the challenge of getting a newborn to sleep through the night.

What the 2025 Reading List Reveals

Taken together, the private equity best business books of 2025 carry a clear signal: the PE leaders performing at the highest level are simultaneously focused on operational excellence in the portfolio and intentional life design for themselves.

The business books — The Outsiders, Traction, The Innovator's Dilemma — are the tools of the trade. But the life design books — Die With Zero, The Second Mountain, From Strength to Strength — suggest a more sophisticated self-awareness: that sustainable high performance requires knowing why you're optimizing, not just how.
