Kool-Aid Advertising: When Marketers Start Believing Their Own Story

Kool-Aid advertising is what happens when a marketing team becomes its own most enthusiastic audience. The work looks confident, the messaging feels tight, and everyone in the room is nodding, but the people it was made for are largely unmoved. It is a pattern I have seen across agencies, client-side teams, and boardrooms: the gradual drift from what the audience needs to hear toward what the brand wants to say.

It is not born from laziness. It is born from proximity. The longer you live inside a brand, the harder it becomes to see it the way a stranger does.

What Does Kool-Aid Advertising Actually Look Like?

The phrase “drinking the Kool-Aid” gets used loosely, but in a marketing context it has a specific shape. It is the brand that writes headlines only its own employees would find compelling. It is the campaign brief that spends three paragraphs on the company’s heritage and one sentence on the customer’s problem. It is the product launch that assumes everyone already understands why the category matters.

I saw it clearly early in my agency career, sitting in a brainstorm for a well-known drinks brand. The founder had to leave for a client meeting and handed me the whiteboard pen with about thirty seconds of context. The room was full of people who had worked on that brand for years. They had strong opinions, fast answers, and a shared vocabulary built up over many campaigns. What they did not have was any meaningful distance from the product. Every idea that landed well in the room was built on assumptions the audience had never agreed to. The work that came out of that session was technically accomplished and almost entirely self-referential.

That is the texture of Kool-Aid advertising. It is not bad craft. It is misaligned craft, work that is optimised for internal approval rather than external persuasion.

Why Internal Consensus Is a Warning Sign, Not a Green Light

Most marketing teams treat internal alignment as a precondition for good work. Get everyone in the room, get everyone nodding, then go to market. The problem is that internal consensus and market relevance are not the same thing, and in many organisations they are actively in tension.

When a team has been working on a brand for a long time, they share a set of assumptions about what the brand means, what makes it different, and what customers care about. Those assumptions get reinforced every time a piece of work gets approved. The approval process itself becomes a filter that removes anything that feels unfamiliar or uncomfortable to the people in the room, which is often the same thing as removing anything that might actually surprise or move the people outside it.

I managed a team through a period of significant growth, scaling from around twenty people to over a hundred across a few years. One of the things that became clear at scale was how quickly shared language turns into shared blind spots. The phrases that circulated internally, the shorthand for what good looked like, the implicit rules about what the brand would and would not do, all of it made the team faster and more coherent. It also made the work more predictable in ways that were not always visible from the inside.

The signal I learned to pay attention to was not whether people disagreed in the room. It was whether the right people were in the room at all. If every voice shaping the work came from inside the organisation, the work would reflect the organisation, not the market.

How Performance Data Makes the Problem Worse

There is a version of this problem that is particular to the current era of marketing, and it is worth naming directly. Performance data has given many teams a false sense of market feedback. The numbers go up, the cost per acquisition looks healthy, the return on ad spend clears the threshold, and the conclusion is that the work is connecting. Often it is not. It is capturing.

Earlier in my career I placed a lot of weight on lower-funnel performance metrics. Over time I came to understand that much of what those metrics were crediting to marketing activity was going to happen anyway. People who were already interested in the category, already warm to the brand, already close to a purchase decision, those people would convert with or without a highly optimised campaign. The performance data was measuring the harvest, not the crop.

The analogy I keep coming back to is a clothes shop. Someone who has already tried something on is far more likely to buy it than someone browsing from the street. Performance marketing is very good at finding the people who have already tried something on. What it does not tell you is whether your brand is the kind of thing people want to try on in the first place, or whether you are reaching anyone new at all.

When Kool-Aid advertising runs alongside performance measurement, the combination is particularly misleading. The work talks to the converted, the converted convert, the numbers look good, and the team concludes the messaging is working. The audience that was never reached never shows up in the data.

This is part of a broader pattern worth exploring if you are thinking about how growth strategy actually functions. The go-to-market decisions that determine whether a brand reaches new audiences, or simply recirculates among existing ones, are often made before a single ad is placed. You can find more on that at The Marketing Juice’s Go-To-Market and Growth Strategy hub.

The Anatomy of a Brand That Has Lost the Plot

There are some consistent patterns in brands that have drifted into Kool-Aid territory. None of them are dramatic on their own. They accumulate.

The first is feature-led communication. The brand starts talking about what it does rather than what it solves. This happens because the people closest to the product find the features genuinely interesting, and they assume that interest is transferable. It rarely is. Most customers do not care how something works. They care whether it makes their situation better.

The second is category jargon. Every industry develops a vocabulary, and brands that spend too long inside a category start using that vocabulary as if it is common currency. It is not. When I have judged effectiveness work, one of the clearest signs of a brand that has lost external perspective is the assumption that the audience already understands the category frame the brand is operating in. The audience almost never does.

The third is heritage as a substitute for relevance. “We have been doing this for forty years” is not a reason to choose a brand. It might be a reason to consider it, but only if the forty years are attached to something the customer actually values. Brands that lead with heritage are often brands that have run out of things to say about the present.

The fourth is the absence of a clear antagonist. Strong advertising almost always has a tension at its centre, something the customer is trying to move away from, a problem they want solved, a situation they want to avoid. Kool-Aid advertising tends to be frictionless in a way that removes all the tension. Everything is positive. Everything is aspirational. Nothing is in conflict. And as a result, nothing lands.

What the Research on Effectiveness Actually Tells Us

Without getting into specific attribution claims, the body of work on advertising effectiveness points consistently in one direction: campaigns that reach beyond the existing customer base, that speak to people who are not yet in the market, and that build memory structures around the brand over time tend to outperform campaigns that are optimised purely for short-term conversion among warm audiences.

Kool-Aid advertising tends to fail on the first criterion before it even gets to the second. If the work is built on internal assumptions about what the audience already believes, it will not land with people who do not share those assumptions. And the people who do not share those assumptions are, almost by definition, the growth opportunity.

This is not an argument against performance marketing or short-term activation. Both have a legitimate role. The question is whether the brand is also doing the harder work of reaching new audiences and giving them a reason to care. Without that, performance marketing is not growth. It is extraction.

BCG’s work on go-to-market strategy in financial services makes a related point about the risk of optimising for existing customers at the expense of reaching evolving audiences. The dynamic is not unique to financial services. Any brand that has been in market long enough to have a loyal customer base faces the same pull toward serving what it already has rather than building what it needs.

How Organisations Accidentally Reward Kool-Aid Thinking

The structural incentives in most marketing organisations push toward internal approval rather than external effectiveness. Campaign timelines are tight. Stakeholder management takes up a disproportionate amount of energy. The easiest way to get work through the process is to make it feel familiar to the people approving it.

When I was running agencies, the work that caused the most friction internally was almost always the work that performed best in market. Not because difficulty is a proxy for quality, but because genuinely fresh thinking tends to feel uncomfortable to people who are close to the brand. It does not match the existing mental model. It requires the approver to trust a perspective they do not fully share.

The inverse was also true. The work that sailed through the approval process, that everyone agreed was solid and on-brand and well-executed, was often the work that produced the flattest results. It was optimised for the room, not the market.

This is a structural problem, not a talent problem. You can have a highly capable marketing team and still produce Kool-Aid advertising if the process systematically filters out anything that challenges internal assumptions. Fixing it requires changing the process, not just hiring better people.

The Forrester perspective on scaling and organisational agility touches on this tension between internal coherence and external responsiveness. The teams that scale well tend to be the ones that have built feedback loops from outside the organisation, not just within it.

Breaking the Pattern: What Actually Works

The antidote to Kool-Aid advertising is not more research. More research conducted by the same team, interpreted through the same assumptions, will tend to confirm what the team already believes. The antidote is structured discomfort: deliberately introducing perspectives that have no stake in the existing narrative.

There are a few practical ways to do this. The first is to separate the people who make the work from the people who approve it, and to include in the approval process at least one person who has no prior relationship with the brand. Not a focus group. A single, commercially literate person who can say “I don’t know what this means” without it being filtered through politeness.

The second is to test the work on people who are not already customers. Not to get a numerical score, but to understand whether the core message lands without the context the brand takes for granted. If someone who has never heard of the brand cannot tell you what problem it solves within thirty seconds of seeing the work, the work is not doing its job.

The third is to audit the brief before the work starts. Most Kool-Aid advertising begins in the brief, not the execution. If the brief is written from the brand’s point of view rather than the customer’s, the work will follow. A brief that starts with “we want to communicate our commitment to quality” is a Kool-Aid brief. A brief that starts with “our target customer currently believes X, and we need them to believe Y” is a brief that has a chance of producing work that moves people.

The fourth is to measure what changes in the market, not just what converts in the funnel. Brand tracking, category share of consideration, new customer acquisition rates, these are imperfect measures but they tell you something about whether the work is reaching beyond the existing base. Conversion rates alone tell you almost nothing about whether the brand is growing or simply harvesting.

Tools that help teams build feedback loops from real user behaviour, rather than relying on internal assumptions, are worth taking seriously. Hotjar’s work on growth loops and feedback is a useful reference point for teams trying to build that kind of external signal into their process.

The Product Launch Test

Product launches are where Kool-Aid advertising does its most visible damage, because the stakes are high and the internal enthusiasm is at its peak. Everyone who has worked on the product believes in it. The launch team has been living with it for months or years. By the time the campaign goes to market, the people making it have forgotten what it is like to encounter the product for the first time.

BCG’s analysis of successful product launches in complex categories identifies the ability to communicate value to an uninformed audience as one of the critical differentiators between launches that build momentum and launches that stall. The principle holds well beyond biopharma. Any launch that assumes prior knowledge is a launch that has already narrowed its addressable audience.

The test I apply to launch campaigns is simple. Can someone who has never heard of this product, this company, or this category understand what it does and why it matters from the campaign alone? If the answer requires any prior knowledge, the campaign is not ready.

Vidyard’s research on untapped pipeline potential for go-to-market teams points to a related gap: the revenue that is never reached because the top of the funnel is not working hard enough. Kool-Aid advertising is one of the primary reasons the top of the funnel underperforms. It talks to people who are already there rather than giving new people a reason to enter.

The Harder Question Behind All of This

There is a question that sits underneath the Kool-Aid advertising problem, and it is one that most organisations avoid because the answer is uncomfortable. Who is this work actually for?

In most cases, marketing work serves two audiences simultaneously: the external audience it is nominally aimed at, and the internal audience whose approval it needs to exist. When those two audiences are in tension, the internal one tends to win, because it controls the budget, the timeline, and the sign-off. The external audience has no vote in the process.

The brands that consistently produce work that moves markets are the ones that have found a way to weight the external audience more heavily in the process. That might mean a CEO who genuinely defers to customer insight over their own instincts. It might mean an agency relationship built on honest challenge rather than comfortable agreement. It might mean a measurement framework that makes it impossible to claim success without evidence of external impact.

Whatever the mechanism, the underlying commitment is the same: the work exists to change something in the market, not to make the people who made it feel good about it.

That shift in orientation, from internal validation to external impact, is what separates brands that grow from brands that circle. It is also what separates marketing that builds commercial value from marketing that generates activity without consequence. If you are working through how to make that shift at a strategic level, the Go-To-Market and Growth Strategy section of The Marketing Juice covers the frameworks and decisions that sit behind it.
