Client Insight and the Case for Marketing — The Evidence, the Gap, and What Closing It Requires

The first two articles in this series established two things. First, that customer insight is one of the most politically consequential capabilities a B2B organisation can build — and that its persistent underdevelopment is not a capability failure but a power problem. The function that genuinely owns customer insight gains authority over the evidence base against which every other function’s assumptions get tested. Organisations sense this, even when they don’t articulate it, and the resistance to clear ownership reflects that discomfort as much as any structural complexity. Second, that the default solution — delegating customer understanding to sales — persists not because it works, but because it is the path of least organisational resistance. It produces enough surface-level customer knowledge to make the question feel answered, while leaving the deeper strategic gaps permanently unexamined.

This article makes the affirmative case. Customer insight should sit with marketing. Not because marketing claims the territory, but because of six structural advantages that no other function shares. Before making that case, however, there is a prior problem worth naming honestly — because in many B2B organisations, marketing has already moved away from the capability that would justify the claim.

What marketing is actually for

Before the structural argument, the foundational one.

The core purpose of marketing is to generate loyal, profitable customers. Not to produce campaigns, not to fill pipelines with leads, not to build brand awareness as an end in itself. Those are instruments. The purpose is customers — customers who return, who grow, who refer, and who do so because the organisation understood them well enough to create genuine value for them.

That understanding is not incidental to marketing’s function. It is the foundation of it. The Chartered Institute of Marketing defines marketing as the management process responsible for identifying, anticipating, and satisfying customer requirements profitably. Every word in that definition is deliberate. Identifying — not assuming. Anticipating — not reacting. Satisfying — not just communicating. Profitably — connected to commercial outcomes, not activity metrics.

Generating loyal, profitable customers from a deep understanding of their challenges, opportunities, needs, opinions, and behaviours: that is what marketing exists to do. Customer insight is not an add-on to that purpose. It is the prerequisite for it. And that is precisely what makes marketing the natural strategic owner — not by assertion, but by definition.

The repositioning problem

The argument runs into an immediate practical obstacle. In many B2B organisations, marketing has been repositioned — gradually, and often without an explicit decision — into a comms and demand generation function. Brand governance, content production, campaign management, MQL targets, performance dashboards. These are legitimate and necessary activities. But they describe a narrower mandate, and one that has quietly displaced the deeper strategic work that marketing’s core purpose requires.

The reorientation has happened for understandable reasons. Measurement frameworks reward activity visibility. Business pressure favours short-term pipeline contribution. And as we established in the first article, the political cost of claiming strategic authority over customer insight is real — it creates friction with sales, with product, with leadership teams accustomed to acting on assumption. Retreating into execution is, in its own way, the same convenient solution that defaulting to sales represents. It avoids the uncomfortable conversation.

But the cost is significant. When marketing is defined by its outputs rather than its strategic contribution, it loses the credibility — and the organisational expectation — to own something as consequential as customer understanding. The capability case for marketing as insight owner is strong. In many organisations, the current operating reality has already moved in the opposite direction.

Six structural advantages

The structural case nonetheless holds, and it is worth making clearly.

Marketing is the only function with visibility across the full customer journey. As DemandLab’s analysis states directly, marketing touches customers first, interacts with them more frequently, and supports them across a longer stretch of the journey than sales, product, or support. That breadth is not a marginal advantage. It is the foundation for the kind of pattern recognition — across segments, across buying stages, across the competitive landscape — that produces genuine strategic insight rather than deal-level intelligence.

Marketing owns the analytical infrastructure for systematic customer research. Voice-of-customer programmes, buyer persona development, market research, competitive intelligence, journey mapping — these are marketing methodologies. The martech stack that marketing functions have built and invested in provides the infrastructure to collect, analyse, and activate insight at scale. Directive Consulting’s model positions marketing operations at the centre of insight distribution, with revenue operations owning the definitions and schemas that make that distribution consistent. The capability base exists. The question is whether it is being applied to strategic intelligence or to campaign optimisation.

Marketing Week’s 2024 survey of 600 B2B marketers found customer insight rated as the single most critical skill for future marketing success at 54.4% — ahead of commercial focus, creativity, and collaboration. The profession’s own senior practitioners understand what the foundation of effective marketing requires. The gap is between that understanding and what many organisations actually resource and expect from their marketing functions.

The CMO is uniquely positioned as the organisational voice of the customer at senior level. Ricky Abbott of Transmission Agency argues that marketing is the only function that can truly own the customer — having the widest and deepest insight, while noting that sales own customer conversations but from a smaller universe that sometimes skews insights to fit their own needs. Forrester is equally direct, calling on B2B CMOs to become custodians of customer insight — transitioning teams from list managers and campaign number-crunchers to strategic insight generators.

And the performance data from Jason Ball’s B2B Effectiveness Engine research, across more than 1,000 senior marketers, is unambiguous: strategy, differentiation, and customer insight are upstream foundational factors with significant impact on everything downstream (Considered Content). Not supporting factors. Upstream determinants. Organisations that build this capability systematically outperform those that don’t — and the gap is measurable.

The structural model varies by scale

How marketing owns customer insight will look different depending on organisational size and complexity. For SMBs, centralising insight within marketing is the practical and effective model. For mid-market companies, a hub-and-spoke approach — with marketing as the strategic hub — provides the balance between rigour and business proximity. BCG’s benchmarking indicates that a hub-and-spoke model requires a minimum of seven to nine full-time employees to function effectively. For large enterprises, a Centre of Excellence that sets standards and enables organisation-wide capability, with marketing as the primary strategic owner and distributor of insight, represents current best practice — a model that Forrester’s research associates with the highest levels of customer insight maturity. In B2B SaaS specifically, product marketing has emerged as the natural home for this capability, with the Product Marketing Alliance’s 2025 data showing 78.7% of product marketers now owning sales enablement, with customer research as a foundational responsibility.

The structural model matters less than whether the three conditions for any model to work are genuinely in place.

Three conditions — and the seat at the table that has to be earned

The first condition is executive sponsorship. BCG is explicit: organisations whose CEOs are not committed to a fundamentally different customer insight operating model should not attempt a transformation. Without it, the insight function — wherever it sits — produces reports that accumulate unread and recommendations that do not reach the decisions they should be informing.

This leads directly to a point that is often stated as an assumption but should be treated as a prerequisite. The CMO’s seat at the executive table is not guaranteed. In many B2B organisations, marketing does not have a permanent voice in the decisions that matter most — pricing, product direction, go-to-market strategy, resource allocation. That seat has to be earned, and it is earned through the quality and strategic relevance of the insight marketing brings to those conversations. A marketing function that reports on campaign metrics and pipeline contribution is not building the case for a seat at the senior table. A marketing function that owns the authoritative understanding of what the market values, where growth is coming from, and what is blocking it — that function earns the right to be in the room. The CMO’s influence in the business is, in this sense, a consequence of insight ownership, not a precondition for it. Getting there requires demonstrating the value of strategic customer intelligence before the formal authority to own it is granted.

Budget control is the second condition. The insight function must own its research budget, not depend on business units to fund work that may challenge their own assumptions. When insight is funded by the functions it is supposed to challenge, it is not insight. It is validation.

Decision rights are the third condition, and the one most commonly absent. Insight must be wired into specific business decisions — proposition development, pricing reviews, go-to-market strategy, product roadmap — with clear accountability for what happens when the evidence contradicts current direction. Dashboards that update continuously but sit outside any decision process are a reporting capability, not a strategic insight function.

A deep change — and a structural competitive advantage

It is worth being clear about what resolving this properly requires. For most B2B organisations, this is not a marginal adjustment to the operating model. It is a fundamental shift in how the business thinks about customer understanding — who owns it, what it is for, and what authority it carries in strategic decisions.

That is a significant ask. It requires marketing to reclaim a mandate that in many organisations has already been ceded. It requires CEOs to sponsor a capability that, as we established in the first article, redistributes organisational influence in uncomfortable ways. It requires sales, product, and other functions to accept that their claims about customers will be tested against evidence they did not generate. None of that is straightforward, and none of it happens through structural diagrams alone.

But the organisations that are willing to make that change, and to sustain it with the conditions required, gain something that is genuinely difficult to replicate. Systematic customer insight — owned clearly, resourced properly, connected to decisions — is a structural competitive advantage. It compounds over time. The deeper the organisation’s understanding of what its customers value, the more precisely it can build propositions, allocate resources, and identify where the next growth opportunity lies before competitors do. Bain’s research shows that B2B loyalty leaders — companies that have built genuine customer understanding into their operating model — grow four to eight percentage points above market annual growth rates. That gap does not close quickly. It widens.

Most B2B organisations are competing on execution. They are optimising campaigns, refining targeting, testing channels, and measuring clicks. The organisations that invest in resolving the upstream question — who owns the deep, systematic understanding of what our customers actually value — are competing on a different basis entirely. Not louder. Not faster. Fundamentally better informed.

That is the opportunity that the consultancy frameworks, the maturity data, and the performance research all point toward. Not a solved problem with a clear consensus answer — as the first article established, it is anything but. But a genuine and durable source of competitive advantage for the organisations willing to do the hard work of claiming it.
