Your marketing team runs a dozen tools. Probably more. Every one of them was bought for a good reason: to understand your customer a little better, to answer their questions a little faster.

So why do more tools so often leave you with more dashboards and fewer real answers? And why, at exactly that point, is everyone reaching for AI to fix it? Sorting that out is what martech stack consolidation is really about, and it is the step most teams skip right before they make things worse.

Quick definition first, because not everyone lives in this world. Your martech stack is simply the collection of software your marketing runs on. The analytics, the email platform, the CRM, the ad tools, the dozen dashboards nobody quite remembers buying. Stitched together, that pile is your stack.

How your martech stack got away from you

Nobody sets out to run a dozen tools. It accumulates. You start with two or three that clearly earn their place, then add one for a problem that felt urgent, then another a vendor swore would tidy up the last one. Scott Brinker’s industry map now lists more than 15,000 marketing tools to choose from, so there is always a defensible next purchase.

Each decision makes sense on its own. The sum does not. Gartner has found that marketers use less than half the software they pay for. In my experience, buyers worn down by the sprawl now want fewer suppliers, not more. What you are left with is a system no single person fully understands.

Nobody buys a bloated stack on purpose.
You assemble it one reasonable yes at a time.

Why AI makes a messy stack worse, not better

Here is the uncomfortable part. Garbage in, garbage out. Sh*t in, sh*t out. You know the rule. You just never pointed it at your own tools.

AI does not clean up a fragmented stack. It runs on whatever you feed it, and if that is duplicated records, three conflicting sources of truth, and definitions nobody agreed on, the model will hand you confident nonsense, faster and at scale. AI amplifies the coherence you already have. If you do not have any, it amplifies the chaos.

AI does not fix a fragmented stack.
It just lets you be wrong faster, and at scale.

The consolidation bet I made (and the part I would reconsider)

Across my years on the corporate side, at L’Oréal and later at EnBW, I kept making a version of the same bet. We pulled as much as we could onto Google. One ecosystem, one login, one version of the numbers. And it worked. Reporting got faster. The team stopped arguing about which dashboard was telling the truth.

Would I make the exact same call today? I am genuinely not sure. Consolidation buys you coherence. It also buys you lock-in. The single source of truth that made us fast also made us dependent on one company’s roadmap and one company’s pricing. That trade is real, and anyone selling you “just simplify everything” is skipping the honest half of the conversation.

Martech stack consolidation is about coherence, not fewer logos

So the goal is not fewer tools for vanity. Ripping out six logos to feel lean is theatre. The goal is coherence: your people and your future AI working from the same clean inputs, the same definitions, the same single answer to your customer’s one question. That is the version of martech stack consolidation worth doing, and it is exactly the kind of unglamorous groundwork I end up doing with clients before anything clever gets switched on. More on how I work is on the services page.

Five checks before you let AI near your stack

Enough principle. Here is the practical part. Before I let a client bolt AI onto their marketing, we run the same five checks. None of them are glamorous. All of them decide whether AI makes you sharper or just wrong faster.

1. One source of truth for the customer. Name the single system that holds the real view of a customer. If three tools each claim that job, you have none.
2. Numbers that agree. Pull the same metric, say last month’s sales, from two different tools. If they disagree, your reporting is fiction, and AI will only scale the fiction.
3. Tools someone actually uses. For every tool, name the person who logs in each week and the decision it drives. No name and no decision means it is a subscription, not a tool.
4. Clean handoffs. Track every point where data moves by hand: export, reformat, re-import. Each manual bridge is where the truth quietly breaks.
5. A real reason for every tool. If the honest answer to “why do we have this?” is “a vendor said it would fix the last one,” you just found the first thing to cut.

Work through those five honestly and you will know what to consolidate and what to switch off, long before you spend a cent on AI. If you want a second pair of eyes on yours, that is a conversation I am happy to have.

Your customer still only has one question. Build a stack that can answer it. If this struck a nerve, let us talk, or come find me on LinkedIn, where I think out loud about this most weeks.
