Sound Decisions

Bad decisions don't feel bad when you make them. This is where we take the calls that decide everything else — and make them visible: original research, dated cases, and frameworks you can scan in a minute or sit with for an evening.

Start here
For marketing leaders

Liquid Death Moved the Money Down. The reason it gave is not the reason it works.

The brand is putting the majority of its 2027 media into retail networks and says awareness is no longer the problem. Its own tracking puts the widest gap at the awareness step, and what the money buys is a measurement.

For marketing leaders

Chase Cut 395,000 Websites. Nine years later the industry caught up.

The waste in programmatic advertising was measured, named, costed and publicly pledged against. Three months after the pledges, sixteen of the seventeen companies that had measured it were still buying it. What finally moved the number was not better data.

For marketing leaders

Coca-Cola Ran It Again. The second time was the decision.

The first AI Christmas ad was called an eyesore and AI slop. A year later the company made another one, bigger, and said so on purpose. What it weighed is the same thing sitting in your meeting right now — and the evidence everyone reaches for says something neither side expects.

For marketing leaders

Private Label Took the Record. It couldn't take the price.

Store brands reached the highest unit share they have ever held in the first half of 2026, and their dollar sales did not move. Nearly half of all private brand growth came from one channel. The threat is real, and it is not where the share deck says it is.

For marketing leaders

Nobody Had the Conversation Sony Was Having

Six comment sections around the launch of Marvel’s Wolverine, roughly 1,800 comments, counted once per person. The argument replaces itself at every stage — discs before release, story and length after play — and almost nothing carries between them. One word survives all three.

For marketing leaders

AI Agents Are Learning to Buy. The Brands Haven’t Said a Word.

Google published an open standard for AI agents to buy from retailers. The card networks, platforms and biggest retailers have written agentic commerce into their SEC filings. Twelve of the largest packaged-goods makers haven’t used the word once. When an agent shops, the pack and the ad go unseen.

For founders

Coke Built It. Pepsi Bought It.

A jab step costs the attacker a step and the defender his balance. Two prebiotic soda startups raised under $100 million between them and made Coca-Cola and PepsiCo commit. One built. One bought for $1.95 billion. The third answer belonged to the challenger.

For marketing leaders

City Stopped Tuning and Bought a Finisher

Manchester City won three league titles in four years and kept losing the one game that decided Europe. In 2022 it stopped tuning, paid £51.2 million for one striker, and changed the team around him. The rebuild is the part brand teams skip.

For founders

What the Ad Reads Bought

Two companies bought the same kind of attention on YouTube. One grew while spending a smaller share each year. The other spent more than half its revenue on advertising and lost customers.

For marketing leaders

The Flip Flop That Isn't

If Omnicom wins Coca-Cola's North American media, it won't have switched sides. It will be working both. And the filings show the two cola companies betting in opposite directions.

For marketing leaders

Takis Beats Doritos. The attention moved; the portfolio didn't.

One Grupo Bimbo brand draws nearly twice the US searches of Doritos. Measure a big food portfolio the same way, across nine categories, and its strongest brands turn out to sit where attention is thinnest.

For marketing leaders

Same Cocoa Shock, Two Answers. Mondelez cut. Hershey held.

Cocoa more than tripled and two chocolate makers lost over ten points of gross margin. One cut advertising by a fifth; the other kept spending. Both calls were in the public filings before anyone could judge them.

For owner-principals

Your Next Client Is Already Inside This One. The pitch is the most expensive door.

Every professional firm, from ad agencies to law firms, finds most of its new work the same way: someone who already worked with them tells someone else. The decision that matters is where you spend the hours that produce that.

For marketing leaders

On Didn't Sign Mbappe. They bought a category.

Most athlete deals are awareness machines. They generate impressions, not growth, and the peak athlete is the most expensive version. On's deals are structured differently, and the evidence for that distinction is worth around half a billion dollars. The question is whether the model translates from running shoes to football boots.

For founders

The Buyer Wrote Down What They Bought From You. And they said why.

Every entry in this series so far has been written from the founder's chair. This one is written from the buyer's, because the assumptions in their model are the ones your price was built on — and years later they publish which ones were wrong.

For marketing leaders

Change the Question, Change the Ranking

Ask an assistant the same buying question two normal ways and the brands it recommends barely overlap. The number on your AI visibility dashboard is mostly a property of the tracker, not of your business.

For marketing leaders

A Third of the Shelf. Two percent of the growth.

Roughly a dozen major consumer companies are running the same restructuring playbook simultaneously, and most are on their second or third round. One restructuring is a correction. Four in a row is a system that cannot locate its own constraint.

For founders

ESPN Needs 30 Million People to Pay for It. Nobody knows how many do.

For three decades the bundle meant ESPN never had to find out what it was worth to anyone in particular. That question is now the only one that matters, and the company stopped publishing the number that would answer it in the same month it started asking.

For founders

The Rule That Never Moved

One company's productivity rule has held for nineteen years, through four CEOs and a write-down. It is not what anyone gets paid on — and that is exactly why it held.

For owner-principals

The Fear Tariff. The budget cut arrives before the cost does.

The last time a tariff shock hit, the marketing cut came months before any cost did, and the recovery overshot. Canada's counter-tariffs are now in force and the U.S. has escalated. The cut that matters this quarter is probably not the one anyone is watching for.

For marketing leaders

Starbucks Ran the Numbers on Its Own Turnaround

A pre-registered read of seventeen Starbucks growth decisions came back the opposite of what I predicted — and a price increase was never the move it made.

Note

Build It Anyway

Nobody is coming to look at it. The two most common responses to that are both lies, and both of them let you stop. A note — no research behind this one.

For owner-principals

The Budget Line. Optimism is up. Investment isn't.

More than two-thirds of agencies expected this year to beat last year. Fewer than half expected to invest in it. What crosses that gap is not what saves time; it is what gets a firm found, and what proves it is worth the fee.

For marketing leaders

Nobody Pays You Extra for Being Honest. But Half of Them Leave When They Catch You.

Three percent of the people who say they care about ethics actually buy that way. So integrity is not a premium. It is insurance — and the bill for skipping it arrives later, larger, and lands first on the people who could least afford the product.

For marketing leaders

If You Take the Quality Out, Don’t Be Surprised When Walmart Puts It Back In

Consumers rank a price increase as the least unfair way to handle rising costs. Quietly cutting the quality is the most. The industry spent four years choosing the second one.

For owner-principals

The Rebate Closes Before the Shoot Starts. What $1.5 billion of Texas film money means for an agency.

Texas is spending about $1.5 billion on moving-image production through 2035, and commercials qualify. They collected about one percent of the last cycle, partly because the rates are low and partly because the window closes before most agencies think to ask.

For marketing leaders

The Memory Isn't Yours. You're Asking to Borrow It.

Nostalgia is not what brands reach for when they run out of ideas — the healthiest companies use it most. But what it reliably buys is attention, and almost nobody measures the rest.

For marketing leaders

Nine Forecasts and No Evidence. Why Product Innovation Actually Fails.

The market sorts winners from losers four weeks after launch. The approval chain spends months getting there — and every gate along the way is a guess, not an observation.

For founders

Purely Elizabeth Took Eight Years to Raise $3 Million. That's Why She Was Still in the Room.

Ferrero is buying Purely Elizabeth. Seventeen years on, the founder is still the chief executive — and the reason traces back to a money sequence she started in 2009, not to the deal itself.

For founders

Hope Isn't a Strategy. Every Strategy Starts as One.

A plan can be board-approved, sized and scheduled and still be hope wearing a plan's costume. The difference is three things you can write down, and most companies never write the third one.

For owner-principals

Creative Is Now a Line Item. Three holding companies priced it three ways.

Between July 16 and August 6, the three largest agency holding companies each reported what creative work is worth inside their business. One is moving capital away from it, one reported it shrinking, one is growing it slower than media. What they all did first is the finding.

For owner-principals

The Ground Nobody Was Defending

The challenger's real starting position isn't unknown — it's unattributed. How to build a position against dominant incumbents without competing with any of them, and why the category never stays won.

For owner-principals

Leaving Isn't the Skill. Leaving With Something Is.

Capable people exit structures that were capturing most of their value every year, and most are never heard from again. The difference is rarely courage — it's what they carried out, and what the contract did with the rights.

For marketing leaders

Additions Are Free. Which Is Exactly Why They Don't Work.

Four years of maximum support produced four years of rejection. What finally moved the position was everything the company gave up — and why a repositioning consumers believe is one they can see you paid for.

For marketing leaders

Your Best Year on Paper Can Be the Year the Brand Starts Dying

Contracted revenue keeps arriving long after the relationship that earned it has begun to fail. WWE posted the strongest financials in its history the same year every audience metric collapsed — and nobody was lying to anybody.

For marketing leaders

The Marketing Job Is Derived Power. That's the Design, Not the Flaw.

You don't own the product, the roadmap, or ultimately the customer. Your function is to raise what the market will pay for something that isn't yours — and treating that as a defect is the most expensive mistake available in the role.

For owner-principals

AI Doesn't Give You Leverage. It Multiplies the Process You Already Have.

Nearly every agency now uses AI, and the most common operational complaint is still inefficient process. The two facts explain each other: the tools multiply the process a firm already has, and most firms have less of one than they think.

For owner-principals

Anyone Can Look Like You Now. What is left is what you know.

Logos, awards, case studies and credentials can now be produced without the work underneath them. When proof gets cheap, buyers discount all of it, and the discount lands hardest on the firms that earned theirs.

For owner-principals

Your Best Clients Are the Ones You Undercharged.

Every client relationship runs a quiet balance: the client gets more than they pay for, or less. The accounts tilted toward the client are the ones that last, and the agencies losing the others are usually looking for the reason in the wrong place.

For owner-principals

When the Client Wins, They Win. Three tests for an agency whose fate is bound to its client's.

Most agency rankings count awards or revenue. Neither tells you whether an agency wins only when its client does. Three tests do: a client-credited result, a relationship that survived a real test, and a fee that moves with the client's outcome. The third is almost never public.

For founders

Value Creation Is a Business Model, Not a Moral Posture

Costco, Larian, and BuzzFeed made the same quiet decision differently — how much of the value they created to keep. The arithmetic favored the ones who kept less.

For marketing leaders

Your Velocity Number Means Three Different Things

Units per store per week, sales per point of distribution, dollars per million ACV — all called velocity, all in daily use, and they can point in opposite directions in the same quarter. Your board hears one number.

For marketing leaders

Most of Your Marketing Budget Is Rent

A large share of what you're accountable for isn't marketing at all — it's contra-revenue, paid to retailers for access. Until you separate the rent from the demand, every efficiency conversation is about the wrong number.

For marketing leaders

The Spend You Inherited Is Two Different Problems

Every inherited budget holds spend that can't prove it works and spend you can't see yet. They look identical on a spreadsheet — and cutting them the same way is the most expensive mistake available in your first quarter.

For owner-principals

You Can Refuse the RFP and Still Win Clients. The pitch is where you accept the terms.

The RFP is not where an agency wins the work. It is where it accepts the terms, at the moment it has the least leverage it will ever have with that client. Two questions on the first call change the economics more than the fee does.

For founders

Poppi Didn't Go Viral by Accident. Two Decisions Came First.

The Super Bowl ads and hot-pink cans were the result, not the cause. Two decisions — made years before anyone was watching — turned an apple-cider-vinegar tonic into a near-$2B exit, and each one carried a bill.

For owner-principals

They’ll Pay for the Work. They Won’t Pay for the Thinking.

Strategy goes on the estimate, and strategy comes off the estimate. The usual answer is to argue that strategy is valuable. The numbers point somewhere less comfortable: this is a packaging problem, and the package costs more than the line was ever worth.

For owner-principals

You Don’t Need More Clients. You Need Longer Ones.

The industry's default route to growth is more people and more logos. On its own published numbers, that route buys revenue and gives up profit. The trade almost nobody is running is the one on the clients they already have.

For owner-principals

Where AI Actually Pays in an Agency. The skeptic was half right.

The most quoted AI statistic says 95 percent of pilots returned nothing. The findings underneath it are more useful: what the paying minority bought, how they measured it, and the risk most agencies are already carrying without having bought anything at all.

For owner-principals

The Market You Proved. A $4.4 trillion economy, a 4% budget.

The case that the U.S. Latino market matters was made decades ago and won. The budgets never followed: brands still plan under four percent of advertising for a fifth of the country. For specialist agencies, the next fight is not proving the market. It is collecting on it.

For owner-principals

How to Win Houston's Growing CPG Market. The shelf is recruiting. The platforms are self-serve.

Houston's consumer brands are forming in plain sight, recruited by the state's biggest grocer and handed self-serve tools to run their own shelf campaigns. What is left for an outside firm is the part no platform supplies: knowing which few moves change velocity.

For owner-principals

Houston Is Booming. Will Your Agency Boom Too?

Houston added nearly 127,000 residents in a year and ranked third among major metros for job growth. Its professional-services firms had a harder 2025, and the pressure that outlasts the dip is pricing: costs rising faster than rates, while AI shrinks the hours an agency bills.

For founders

You Caught the Protein Wave. So Did Everyone.

Every brand on the shelf now claims high protein — so the claim sells nothing. The real growth was never in the attribute; it's in the occasion your brand owns.

For founders

Getting Into Walmart Is the Dream. It Can Also End the Company.

Landing Walmart feels like you've arrived. But the account big enough to make your year is big enough to remake your business and then strand it — and this is the rare danger that comes from winning, not failing.

For founders

When the Money Changes Its Mind

The capital that rewarded growth at any cost just repriced. The move isn't to spend less — it's to cut what can't prove it works, and put everything behind what can.

For founders

Grüns Reached a Billion-Dollar Exit in Three Years. The Decisions Came First.

Unilever bought the greens-gummy brand on June 1, 2026, at an estimated $1.2B. The exit wasn't won in the visible growth — it was decided in a handful of early calls. Here's which ones you can copy.

For founders

Distribution Doesn't Create Demand; It Captures It

Winning more shelves feels like growth. It isn't — distribution can only capture demand you've already built, and expanding ahead of it just starts more clocks you can't beat.

For founders

Why Whole Foods Is Not the Holy Grail

The badge on the whiteboard is a transaction with a posted price — and most founders are carrying a map of the retailer that's a decade out of date, in both directions.

For founders

Can Your Mission Survive Acquisition?

The acquisition doesn't break the mission. It reveals whether the mission was ever structurally protected — in five decisions most founders make years earlier, disguised as something operational.
