AI is coming for the strategy document.

That sentence alone creates anxiety for a lot of consultants, strategists, and agencies. For years, many of us have sold research, audits, positioning exercises, customer personas, content plans, and full strategy documents as premium deliverables. Now, a business owner can sit down with an AI model and generate a surprisingly good version of many of those outputs in minutes.

That doesn’t mean consultants are finished.

But it does mean many consultants are selling the wrong thing.

I’ve been working on a concept I call the Waterline to help make sense of what’s happening.

The waterline is the level your client can reach on their own. Everything below it, they can do without you now. Everything above it is what they’re paying for. And the water keeps rising.

That’s the framework. And if you advise clients on marketing strategy, business growth, or customer acquisition, I think it may be one of the most important ways to think about your offer right now.

Why the Waterline matters for consultants right now

The traditional consulting model assumed clients needed outside help to produce insight.

That was true when gathering information, analyzing competitors, building customer personas, mapping journeys, and drafting plans required a lot of specialized labor.

But AI is changing that fast.

Today, a smart client with a model can often produce:

• A basic competitive review
• A first-draft ideal client profile
• A messaging framework
• A 90-day marketing plan
• Content ideas and editorial structure
• A reasonable first-pass strategy document

Not perfect? No.

Good enough to challenge what many consultants charge for? Absolutely.

That’s why the Waterline matters. It gives consultants a way to evaluate which parts of their work are still premium and which parts have gone underwater.

What is the Waterline?

The waterline is the level your client can reach on their own. Everything below it, they can do without you now. Everything above it is what they’re paying for. And the water keeps rising.

There are only three pieces of vocabulary in this framework:

The waterline

The level a client can reach on their own with a model and the knowledge they already have.

Above the waterline

What they’re paying you for.

Underwater

What they can now do without you, which means you can no longer charge for it.

This distinction matters because underwater does not mean useless.

It means the work is no longer independently valuable enough to sell as premium work.

That’s a critical difference.

The real threat is not AI. It’s being tied to the wrong business model.

There’s an old saying that a rising tide lifts all boats.

That’s true only if the boat can rise with the water.

If it’s tied off too tightly, the incoming water doesn’t lift it. It swamps it.

That’s what’s happening to many consultants right now.

The problem is not simply that AI is getting more capable. The problem is that many firms are still tied to the same deliverables, pricing models, and value propositions that worked five years ago.

The waterline keeps rising. Their business doesn’t.

The firms that thrive will not be the ones trying to defend yesterday’s work. They will be the ones willing to change what they sell.

The Plimsoll line story: why visible lines matter

There’s a historical idea behind this metaphor that makes it even more useful.

In the 1800s, ships were often sent to sea dangerously overloaded. Samuel Plimsoll campaigned for a visible mark on a ship’s hull so people could clearly see whether it had been loaded beyond a safe limit. The British Merchant Shipping Act of 1876 helped establish mandatory load-line markings, which became associated with Plimsoll’s name.

I like that story because the value of a line is not just in what it measures. The value is that it makes something visible that people might otherwise ignore.

That’s what the Waterline does for consultants.

It makes visible how much of what we still pitch, price, and package has already gone underwater.

AI is making strategy cheaper to produce, but not easier to choose

This is where I think many people get the conversation wrong.

A lot of consultants still say something like this:

“AI can do the research, but humans still provide the judgment.”

That may be true, but it is becoming too vague to be useful. And frankly, “human judgment” is beginning to sound like a generic defense mechanism.

A better way to think about it is this:

AI is making it cheaper to produce a strategy. It isn’t necessarily making it easier for a business to make strategic choices.

That’s a much stronger distinction.

A model can produce a strategy document. It can recommend narrowing a target market, identify promising channels, prioritize initiatives, and explain tradeoffs.

But most businesses are not stuck because they lack a document.

They are stuck because they have not made the hard choices the strategy requires.

That’s where the real opportunity still lives for a consultant.

A strategy document is not the same thing as strategy

This is one of the biggest mindset shifts consultants need to make.

A strategy document is useful. But the strategy document is not the strategy.

A strategy is a set of choices. The document is just a record of them.

That distinction changes everything.

If your value is tied to producing the document, you are vulnerable.

If your value is tied to helping a leadership team make, commit to, and act on the right strategic choices, you still have a premium role.

That role may evolve too. The water keeps rising. But for now, it is still where many of the most valuable engagements live.

What remains above the waterline for a marketing consultant?

So what are clients actually paying for now?

Not just information. Not just analysis. Not just outputs.

Increasingly, they are paying for leadership around decisions.

In practical terms, that often means:

• Challenging the owner’s assumptions
• Identifying what matters most
• Separating noise from signal
• Showing what should be ignored
• Surfacing tradeoffs
• Sequencing action based on budget, politics, and capacity
• Helping a team commit to fewer priorities
• Telling a client what will not work
• Connecting strategy to operational reality
• Taking responsibility for a recommendation

This is especially true in founder-led businesses.

Many owners do not need more ideas. They need help choosing among too many ideas.

They do not need a thicker report. They need clarity, commitment, and direction.

Why productized process still matters even if it’s underwater

This is an important point, especially for firms like Duct Tape Marketing that have invested heavily in frameworks and methodology.

A consultant’s process can be underwater without being worthless to the consultant.

In fact, the better your process is productized, the more efficiently you can get to the work above the waterline.

That means frameworks, templates, worksheets, prompts, audits, and SOPs still matter a lot.

They just may not be the thing you lead with in the proposal.

They become the infrastructure that supports the premium work.

That’s why I keep coming back to this simple idea:

Stop charging for the process. Start using the process to get to the decisions worth charging for.

The mistake is not doing work that has gone underwater.

The mistake is building your value proposition around it.

What the Waterline looks like in a Strategy First engagement

This becomes especially clear inside a strategy engagement.

At Duct Tape Marketing, we’ve spent years developing and productizing the research, frameworks, and processes behind our Strategy First methodology. Those processes help advisors deliver consistent strategic work without reinventing every engagement.

But the process and the decisions it supports are not the same thing.

Take a few common examples.

Competitive analysis

The research itself may be increasingly underwater.

But deciding which three findings matter, which 37 do not, and what the company should actually do next may still be above the waterline.

Ideal client persona

AI can help build a persona quickly.

But choosing the segment to focus on, and helping a business accept that the customers they like most may not be the most profitable, is a different level of work.

Core messaging

AI can generate multiple positioning angles.

But choosing the one position a business can credibly own, and helping the team let go of the others, is where the stakes rise.

Marketing Hourglass and customer journey mapping

A model can map stages and identify gaps in the customer journey.

But determining which gap matters most, what should be fixed first, and what the business can realistically support is still a strategic choice.

Our Marketing Hourglass framework looks beyond the sale to the entire customer journey, from Know, Like, Trust, Try, and Buy through Repeat and Refer. It helps reveal where the business needs to focus, but the advisor still has to help the company decide what to do about those gaps.

90-day planning

AI can generate a detailed action plan in seconds.

But cutting the plan down to what the team will actually do is where real value often lies.

In almost every case, the premium work is not creating more options.

It is helping the client narrow options into commitments.

The Waterline Check: a simple exercise every consultant should run

This is where the framework becomes practical.

The Waterline is not just a metaphor. It should drive how you evaluate your offer.

Step 1: Test your three most common deliverables

Take your three most common deliverables and spend 15 minutes producing each one with an AI model such as ChatGPT or Claude.

Use only what a client would know walking into the engagement.

No internal notes. No client history. No files.

Step 2: Mark what came back 80% right

That’s underwater.

Automate it, fold it in free, or stop opening proposals with it.

The work may still be useful, but it’s no longer the foundation of your premium offer.

Step 3: Mark what the model couldn’t touch

That’s above the waterline.

The consequential decisions, the challenges to the original brief, the priorities and commitments the client could not establish independently.

That’s what page one of your proposal should be about.

Then run the Waterline Check again next quarter.

Nobody moves the line for you. And it moved while you were busy.

A question every consultant should ask now

Here is the uncomfortable question behind the entire framework:

If my client walked into our next meeting with a pretty good version of everything I planned to deliver, what would they still need me for?

If your answer is unclear, your offer is vulnerable.

If your answer is “human judgment,” that’s probably not enough.

But if your answer is helping them choose, confronting tradeoffs, deciding what to stop doing, aligning the leadership team, and getting the business to act on its strategy, you’re getting closer to the work that still deserves premium fees.

If you can’t name three decisions you’d make differently from a smart client with a model, you don’t have a premium yet. You have a tagline.

What this means for agencies, consultants, and fractional CMOs

If you sell marketing strategy, advisory services, or fractional CMO services, the Waterline has immediate implications.

1. Reposition your offer

Lead with the strategic choices you help clients make, not the documents you produce.

2. Repackage deliverables

If something is underwater, include it, automate it, or de-emphasize it. Don’t center your pitch on it.

3. Price leadership, not labor

Your highest-value work is increasingly tied to the business consequences of decisions, not the mechanics of producing materials.

4. Build a stronger method

The more repeatable your process becomes, the more energy you can spend where clients still need you most.

5. Re-run the Waterline Check regularly

What was premium six months ago may be table stakes now.

The future of marketing consulting is above the waterline

Consultants don’t need to panic. But we do need to stop pretending yesterday’s premium work will stay premium just because it still takes effort.

The water keeps rising.

Some of the work we used to sell is going underwater for good.

That doesn’t eliminate the need for advisors. It raises the standard for what advisors need to be.

The future belongs to consultants who can move from producing strategy to leading strategic choices.

That is where the value is. That is where the leadership is.

And for now, that is what still sits above the waterline.

Frequently asked questions about AI and marketing consulting

What is the Waterline in marketing consulting?

The Waterline is a framework developed by Duct Tape Marketing to identify what clients can now accomplish independently using AI and what they still need a consultant to provide. The waterline is the level clients can reach on their own. Work below it is underwater, while work above it represents what they’re still paying for.

What does underwater mean in consulting?

Underwater refers to work clients can now accomplish on their own, often with AI. It may still be valuable within a consulting engagement, but it no longer supports the same independent premium fee because the client can produce it without the consultant.

Is AI replacing marketing strategy consultants?

AI is making many traditional consulting deliverables easier and cheaper to produce, including research, audits, customer personas, and strategy documents. However, businesses may still need outside leadership to make difficult strategic choices, resolve competing priorities, and act on recommendations. Consultants need to continually demonstrate where they create value beyond what clients can accomplish independently.

What should marketing consultants charge for in the age of AI?

Marketing consultants should build their offers around outcomes and strategic decisions clients cannot reliably achieve on their own. This can include challenging assumptions, selecting priorities, navigating organizational constraints, securing leadership commitment, and guiding implementation. The value lies in what changes for the client, not simply the documents delivered.

What is the Waterline Check?

The Waterline Check is a quarterly exercise developed by Duct Tape Marketing. Consultants take their three most common deliverables and spend 15 minutes producing each with an AI model, using only information a client would already know. Work the model gets 80% right is considered underwater. Work the client still cannot accomplish independently belongs above the waterline and should shape the consultant’s offer.

How does the Waterline apply to fractional CMOs?

For fractional CMOs, the Waterline highlights the difference between delivering marketing outputs and providing marketing leadership. Research, plans, reporting, and many tactical recommendations may become easier for clients to produce with AI. The fractional CMO must demonstrate value through strategic direction, resource allocation, organizational alignment, and decisions that produce meaningful business results.

Run your own Waterline Check

If you advise clients on marketing, growth, or strategy, I’d encourage you to run your own Waterline Check this quarter.

Take your three most common deliverables and see what a model can produce in 15 minutes.

Then ask yourself what your client would still need from you if they already had those outputs in hand.

That answer may tell you more about the future of your consulting business than any AI prediction ever will.
