What Martech Created
To understand why AdWaste became a $500 billion plague, we need to look not at Google or Meta but at the failings of Martech itself. The uncomfortable truth is simple: customers weren’t stolen by Adtech—they were abandoned by Martech.
The Mirage of Personalisation
Martech promised one-to-one experiences. The reality? Most platforms still deliver eight or ten crude segments for millions of customers. “Women 25–34” or “loyal high-spenders” isn’t personalisation—it’s stereotyping at scale.
Consider the BRTN framework that reveals the true customer distribution: 20% Best customers generate 60% of revenue, 40% Rest customers contribute 30%, and 40% Test customers (dormant or churned) account for just 10%. Yet Martech treats them all with the same blunt instruments. For the Best customers, these campaigns may still convert—they’d likely buy anyway. But for the silent majority—the Rest and Test customers who make up 80% of databases—this broad-brush approach feels irrelevant. They disengage, drift away, and eventually vanish into “One and Done”.
Focus on the Easy Wins
Platforms and marketers alike doubled down on what was easiest: talking to customers who would likely buy anyway. Best customers get the best campaigns because they make the numbers look good. It’s the marketing equivalent of fishing in a stocked pond—impressive catches, but not sustainable growth.
But ignoring the Rest meant ignoring tomorrow’s revenue. The “missing middle”—those who bought once or twice but never returned—became a lost generation of customers. For every brand, this group is the single largest profit leak. And it’s not just lost revenue; it’s the trigger for the reacquisition spiral. When a Rest customer becomes a Test customer (dormant), the only path back is through expensive ads.
Complexity Masquerading as Capability
Another promise Martech made was simplicity. In practice, platforms became so bloated that 60–70% of features go unused. Dashboards multiply, journeys fragment, integrations break, and marketers need armies of specialists just to run basic campaigns. The average enterprise uses tens of marketing tools, yet customer engagement keeps declining.
Faced with this complexity, many brands default to the easy alternative: handing more budget to Google and Meta for quick traffic fixes. When retention tools become too difficult to use, acquisition platforms win by default. Facebook’s ad manager, for all its flaws, at least delivers predictable results with minimal expertise required.
Input Pricing, Zero Accountability
Perhaps the most damaging flaw is how Martech charges. Vendors bill by inputs—emails sent, monthly active users, API calls made—not by outcomes. This model rewards volume, not value. The incentive is to send more campaigns, not to create more conversions.
This creates a perverse dynamic: Martech profits whether retention works or not. Send a million emails that everyone ignores? That’s revenue for the platform. Meanwhile, brands are flooded with vanity metrics—open rates, click rates, engagement scores—that mask the fundamental failure: customers are leaving.
The AdWaste Equation
Put these failures together and the equation becomes inevitable:
- Failed personalisation → 80% of customers ignored
- Focus on Best → Rest and Test abandoned (the 80% who need nurturing)
- Complexity → 60–70% features unused, adoption stalled
- Input pricing → volume without value, no accountability
The outcome is systematically lost customers. And every lost customer is worth their weight in gold to Google and Meta, who happily sell them back through search and social ads at 5–7x the cost of retention. This is why 70% of marketing budgets now flow to reacquisition. Not because Adtech outsmarted Martech, but because Martech left the door wide open.
The Double Taxation of Failure
Think about the economics: every retention failure isn’t just lost revenue, it’s double taxation. First, brands lose the customer’s lifetime value—all their future purchases vanish. Then brands pay again—often more than the original customer acquisition cost—to bring the lost customers back through ads. Because if they don’t, their competitors will. Either way, the profit vanishes into what becomes a permanent leak in the brand’s P&L.
A typical D2C brand with 100,000 customers faces this reality: 20,000 Best customers keep buying, 40,000 Rest customers are slowly disengaging, and 40,000 Test customers are already gone. Martech focuses on the 20,000. Adtech profits from the 80,000. It’s a perfect parasitic relationship—Martech’s neglect becomes Adtech’s nourishment. And the brand bleeds money trying to refill a bucket that Martech keeps emptying.
Martech didn’t just fail to keep customers; it created the very conditions that allowed AdWaste to thrive. By ignoring the missing middle, focusing on features and delinking itself from RoI, hiding behind complexity, and rewarding inputs instead of outcomes, Martech effectively became Adtech’s greatest ally. [It is like in politics where a weak Opposition leader becomes the best friend of the ruling party.]
The result? A half-trillion-dollar tax on growth, paid willingly by brands desperate to win back the very customers they already had. And Martech, the supposed solution, was the cause all along.
