Mind the Gap: Closing the divide between martech stacks, activation, and performance

78% of marketing leaders feel that despite years of significant investment, their martech stacks do not support their business goals.

This is usually framed as a technology problem, but our research points to a more specific diagnosis: Most organizations have built capable stacks that generate insights, but cannot use them at full capacity because the activation architecture is broken.

We call this the Activation Gap — the space between generating insights and being able to act on them.

In the survey, 366 marketing leaders across industries shared the challenges they face, such as:

• 75% are making investment decisions based on partial data, while only 25% describe a fully data-driven environment.
• 47% are only moderately confident in their ability to measure true ROI across channels. The tools are there, but the trust is not.
• 24% use media mix modeling to reallocate budgets based on live performance data, while 86% navigate with last year’s map.

If you’re dealing with siloed data, underutilized tools, and fragmented systems, you’re probably also seeing symptoms like our respondents:

• Data exists, but isn’t unified –  34% cite data quality issues as the biggest barrier
• Agility is a goal, but workflows lack speed –  37% struggle with slow approvals and rigid planning
• Insights are available, but not actioned in real time  – only 35% use real-time insights for optimization
• Personalization is a priority, but hard to scale – 37% find managing data volume and quality a key challenge

Most marketing teams don’t know where they stand on activation maturity—until it’s too late. This report helps you diagnose the gap and fix it, with clear steps to move from insight to impact.

We also provide an easy Martech Maturity Scorecard, a quick self-assessment for marketing leaders to assess their stack maturity, and reveal the critical steps needed to close the activation gap.
