What CMOs Are Reading in 2026

What CMOs Are Reading in 2026

Most CMO reading lists are just lists. Titles stacked together with cheerful summaries, no argument for why they belong together, no honest accounting of where they disagree with each other. This one is different.

These books share a common thread: they all push back against something. Against the assumption that loyalty is where growth lives. Against the idea that strategy is just a longer tactical list. Against the comfortable belief that doing what worked last year will work next year. If you read them in sequence, they build on each other in ways that aren't obvious from the cover copy.

Some of these titles have been on CMO shelves for years. They're here because the arguments are still being ignored. Others are newer. All of them are worth your time.

The Books

Never Always, Never Never: Strategic Marketing in an AI World by Patrick Gilbert

Patrick Gilbert builds his argument through a detailed account of launching Grown Brilliance, a lab-grown diamond brand, from a bootstrapped startup to a business on pace for significant annual revenue. The premise is embedded in the title: no tactic is always right, no tactic is always wrong. Context determines everything. The strategic decisions that drove that growth, spending aggressively during the slowest period of the year, letting ROAS deteriorate deliberately, prioritizing mental availability over tidy attribution reports, would have been flagged as irresponsible under conventional performance marketing logic. That tension is the book's actual subject.

Never Always, Never Never is one of the few marketing books written from inside the execution, not from a distance. The chapters on strategy vs. tactics in marketing are among the clearest treatments of that distinction in print. Gilbert's argument that most digital advertisers have been running extraction strategies, not growth strategies, is blunt and hard to refute. The Grown Brilliance case study makes the abstract concrete in ways that matter for any CMO managing a brand that's trying to cross from challenger to category leader.

Good Strategy/Bad Strategy: The Difference and Why It Matters by Richard P. Rumelt

Published in 2011 by Penguin Random House, rated 4.7/5 across more than 3,200 Amazon reviews, named by The Economist as one of the best business books of the year, and featured on Harvard Business Review's "10 Must Reads on Strategic Marketing" list. That's a strong record for a book that is fundamentally about something most organizations still get wrong.

Rumelt's central argument is structural. Real strategy has a kernel: a diagnosis that simplifies the challenge, a guiding policy that defines the approach, and coherent actions that work together to execute it. Bad strategy is long on goals and short on everything else. It mistakes aspiration for direction and uses confident-sounding language to paper over the absence of actual choices. The book's value isn't the framework itself. It's the examples of bad strategy, which are uncomfortably recognizable. Most marketing decks fail Rumelt's test before slide three.

This pairs well with Never Always, Never Never. Gilbert's account of the Grown Brilliance launch is essentially a real-world demonstration of Rumelt's kernel: a clear diagnosis of the category, a guiding policy built around luxury positioning before the market commoditized, and coherent actions that held even when short-term numbers turned uncomfortable. Read them together and the connection becomes obvious.

*[The Crux: How Leaders Become Strategists](https://amazon.com/s?k=The+Crux+Richard+Rumelt) by Richard P. Rumelt*

Published in 2023, rated 4.6/5 across more than 1,100 Amazon reviews, and listed in Content Marketing Institute's "37 Best Marketing Books for 2026." Rumelt's follow-up to Good Strategy/Bad Strategy sharpens the operational question: how do you actually find the crux of a challenge when everything feels urgent at once?

Leaders who become good strategists learn to distinguish the pivotal obstacle from the surrounding noise and design focused action around that single point of pressure. For CMOs operating across AI disruption, compressed media attention, and shrinking measurement visibility, the crux question is more useful than ever. Most teams are buried in tactical debates precisely because no one has done the work of identifying what the actual bottleneck is. Read Good Strategy/Bad Strategy first. This one is the applied version.

*[How Brands Grow: What Marketers Don't Know](https://amazon.com/s?k=How+Brands+Grow+Byron+Sharp) by Byron Sharp*

First published in 2010, with a second edition in 2016. Winner of the Marketing Society Book Award in 2011. Rated 4.5/5 across more than 2,400 Amazon reviews. More than any other book on this list, How Brands Grow changed what CMOs argue about at the whiteboard.

Byron Sharp and the Ehrenberg-Bass Institute built the empirical case that brand growth comes from expanding the pool of light buyers, occasional, low-engagement customers who buy infrequently but collectively represent most category volume, not from deepening loyalty among existing customers. Mass reach, consistent messaging, and distinctive brand assets matter more than targeted retention programs. The double jeopardy law shows up here too: smaller brands suffer doubly, with both fewer buyers and lower purchase frequency among those they do have.

Among the most cited and most resisted books in marketing, How Brands Grow draws its strongest pushback from people who have built their careers around loyalty metrics and customer lifetime value models. The data Sharp presents doesn't make those things useless, but it does reorder the priority stack in ways that are uncomfortable for a lot of existing marketing infrastructure. Gilbert references Sharp explicitly in Never Always, Never Never, noting that the Grown Brilliance founder understood the light-buyer principle intuitively even without having read the book. That's the kind of validation that sticks.

*[Unreasonable Hospitality: The Remarkable Power of Giving People More Than They Expect](https://amazon.com/s?k=Unreasonable+Hospitality+Will+Guidara) by Will Guidara*

Published in 2022. A New York Times Bestseller. Rated 4.8/5 across more than 4,100 Amazon reviews, the highest rating on this list by a meaningful margin. Featured in Think Like a Publisher's Best Marketing Books for 2026.

Will Guidara ran Eleven Madison Park when it was named the best restaurant in the world. His book is about how that happened, and the mechanism was deliberate, systematized generosity. Not random acts of kindness, but a genuine organizational commitment to exceeding expectations in ways that people remember and talk about. For CMOs, the relevant translation is customer experience as brand strategy. Not the customer experience team's work as a support function, but the actual experience of interacting with a brand as a primary driver of growth.

The hospitality framing might seem distant from B2B SaaS or performance marketing, but the underlying principle is directly relevant: emotional memory drives future behavior. Les Binet and Peter Field's IPA DataBank research makes the same case from the opposite direction, with decades of advertising effectiveness data. Guidara arrives there through restaurant management. Both are right. Read this alongside How Brands Grow and the emotional advertising effectiveness argument becomes nearly airtight.

How to Read These Together

The sequence matters more than the individual titles.

Start with Good Strategy/Bad Strategy to build the diagnostic vocabulary. Then read Never Always, Never Never to see what genuine strategic discipline looks like when applied under commercial pressure, with real money and real uncertainty. The Crux fills in the process question: how do you find the pivotal challenge when everything is on fire. How Brands Grow resets the underlying assumptions about where growth actually comes from. Unreasonable Hospitality closes the loop on what brands are ultimately trying to build: an emotional relationship that compounds over time.

Why These Books, Why Now

None of these books are about AI tools, automation, or the latest platform update. That's not a gap. CMOs who will navigate the next few years well are the ones with clear strategic frameworks, not the ones who added the most new software to their stack. The brand vs performance marketing tension that runs through almost every one of these titles is the same tension that will define marketing effectiveness for the foreseeable future.

A Note on Where This List Comes From

At AdVenture Media, the reading list has shifted noticeably toward strategy and behavioral economics over the past three years. The reason isn't academic. It's that the tactical playbooks that defined digital advertising's first era have largely run their course. The digital marketing arbitrage model that made cheap-traffic strategies viable is under pressure from every direction.

These books don't offer a replacement playbook. They offer something more durable: a way of thinking about problems that holds up even when the platforms change, the algorithms shift, and the measurement gets harder. That's what CMOs actually need in 2026.
