The $160 billion martech industry can’t answer a simple question: How does it make its customers money?

TITLE: The Martech ROI Paradox: Why $160 Billion in Spending Can’t Prove Its Worth

The Multi-Billion Dollar Marketing Mystery

Global businesses are projected to pour $160 billion into marketing technology this year alone, with McKinsey forecasting this figure to surge to $215 billion by 2027. Despite this massive investment, a fundamental question remains unanswered: How exactly does this spending translate into measurable revenue for companies?

McKinsey’s comprehensive survey of 233 senior marketing and technology leaders—each overseeing annual martech budgets exceeding $500,000—revealed a startling truth. After conducting in-depth interviews with 50 Fortune 500 marketing executives, the consulting firm found not a single leader could clearly articulate how they quantify return on investment from their martech expenditures.

The Complexity Conundrum

The core issue lies in what McKinsey describes as “stack complexity.” Years of accumulating various technologies—from email campaign management systems to personalization engines and analytics platforms—have created bloated, disconnected martech ecosystems., according to market insights

“47% of martech leaders cited stack complexity and integration challenges as primary barriers to realizing value from their investments,” the report noted. This technological sprawl means companies often cannot connect their martech tools to meaningful business outcomes.

Measuring the Wrong Metrics

McKinsey’s research uncovered another critical problem: companies are frequently tracking the wrong performance indicators. Many marketing teams focus on superficial metrics like email open rates or impression counts rather than connecting these numbers to strategic outcomes such as incremental revenue growth or customer lifetime value.

Compounding this issue, organizations often fail to account for the full cost of martech implementation. Many only consider license and subscription fees while ignoring the substantial investments required for integration, maintenance, and employee training., according to additional coverage

The Executive Perception Problem

This measurement failure has created a perception problem in the C-suite. McKinsey found that many executives view martech spending as a “cost of doing business” rather than a growth engine, resulting in limited executive sponsorship and strategic prioritization.

Robert Tas, McKinsey partner and report coauthor, explained the challenge: “The C-suite underestimates what’s really required to implement this and get value out of it—it’s not just hey, I write a check.”

The Talent and Training Gap

McKinsey’s survey revealed that 34% of martech decision-makers cite under-skilled talent as a significant barrier to unlocking value from their technology stacks. Tas compared the situation to purchasing expensive workout equipment but failing to develop a comprehensive exercise regimen.

“Most people end up buying this expensive tool and then they use 10 to 15% of its capability,” Tas noted. “It’s like buying a car without snow tires and not driving it in the winter because you didn’t buy the right things for it.”

AI Agents: The Emerging Solution

McKinsey points to artificial intelligence as a potential solution to the martech ROI dilemma. The report suggests AI “orchestration agents” could autonomously manage data collection, cleansing, and integration tasks, while “design agents” could generate personalized offers and messaging.

Additional AI agents could test and optimize marketing channels and media selection, all managed by a governing layer to oversee the entire martech ecosystem. This approach could help companies eliminate duplicate tools and integrate disparate data sets across organizational silos., as earlier coverage

The AI Implementation Reality Check

Despite the promise, the practical implementation of AI agents faces significant challenges. Salesforce has committed heavily to AI agents with its Agentforce platform, yet CEO Mark Benioff recently acknowledged that AI innovation is “far exceeding” client adoption.

Success stories exist, such as Virgin Voyages deploying AI agents to reduce agency costs and accelerate marketing production. However, other companies have encountered limitations. Fintech firm Klarna initially celebrated AI for helping halve its marketing team size, only to reassign employees to customer service roles after acknowledging that cost-cutting had gone too far.

OpenAI cofounder Andrej Karpathy recently suggested that AI agents might need another decade to overcome cognitive limitations, noting “They don’t have enough intelligence, they’re not multimodal enough, they can’t do computer use, and all this stuff.”

A Path Forward

Tas sees the current moment as an opportunity for fundamental reassessment. “This is our opportunity to take all the sacred cows and challenge them and say, ‘Hey, it doesn’t have to be this way,'” he stated.

As companies continue increasing their martech budgets—with over a quarter of marketing leaders expecting spending to grow by up to 25% in the next three to five years—the pressure to demonstrate clear ROI will only intensify. The solution may lie not in additional technology purchases, but in better integration, measurement strategies, and organizational alignment around what truly drives business value.
