Global marketing effectiveness and foresight consultancy, Gain Theory, today published a new report, ‘Unfinished Business: Closing the Insight-to-Action Gap’, challenging conventional wisdom that marketing insights fail to be actioned because of data.
Despite the clear link between data-driven decision-making and revenue growth, Forrester findings suggest more than half (54%) of business-to-consumer (B2C) marketing decision-makers say the insights their teams deliver are not actionable. And companies that are using insights, can expect to see 32% higher revenue growth than those that don’t.
This demonstrates that for many organisations business value is consistently going unrealised.
Insight to Action report
The new report warns that most organisations are fighting the wrong battle. When insights stall, the instinct is to invest in better data, faster analytics or more advanced technology.
Gain Theory’s report argues that the true barriers are human, cultural, and organisational. And until those are addressed, even the most sophisticated measurement programs will fail to deliver sustained business impact.
“Brands invest heavily in marketing effectiveness, yet business impact often doesn’t materialise”, said Rachel Brook, Global Client Growth Leader at Gain Theory. “Every marketer knows the frustration of un-acted insights.
“The real disconnect isn’t in the ‘what’ or ‘how much,’ but in the human willingness to trust, adapt, and drive those discoveries forward”.
The report identifies three uncomfortable truths facing marketers:
1: You’re generating reports, not actionable insights.
Most measurement programs answer ‘what happened?’ but stop short of explaining ‘why’ or ‘what to do next’, leaving decision-makers without the context to act with confidence.
2: Your organisation favours familiar discord over clarity.
Fragmented measurement and organisational silos create competing versions of the truth, enabling inertia and avoiding accountability.
3: You’re treating a people problem like a technology problem.
Over-reliance on tools overlooks the behavioural, cultural and leadership challenges that determine whether insights drive action or stall.
Against each truth, the report maps five strategic steps organisations can implement to close the gap between insight and impact.
These include:
1: Generate contextualised insights that answer not just ‘what happened?’, but ‘why and what next?’.
2: Prioritise purpose-driven, unified measurement to establish a single source of truth and eliminate conflicting data narratives.
3: Be strategic about priorities and deliberate in progress, building momentum with early wins while planning for larger transformation.
4: Secure leadership commitment and cross-functional alignment, making the business case for executive sponsorship, stakeholder workshops and a culture of low-risk experimentation.
5: Build internal momentum through advocates and accountability, sustaining transformation via empowered champions, continuous education and performance incentives.
Rooted in change management principles, Unfinished Business provides a clear, commercially grounded blueprint for transforming marketing into a data-driven engine for enduring business growth. It reframes best-in-class marketing effectiveness as a cultural and organisational challenge and offers tangible mechanisms for overcoming it.
The findings are supported by “Closing the Insight-to-Action Gap”, a recent pulse survey of senior marketing leaders across multiple industries and regions, conducted by Gain Theory during Q1 2026. Responses were collected anonymously and analysed in aggregate.
