B2B marketing teams now produce more material than ever, and very little of it gets remembered. The two are connected. The fix? A big idea and a theme strong enough to hold everything together.
More content, more authors, more fragments
AI has cut first-draft time from days to minutes. Sales teams personalise campaign emails for every account, regional teams localise, partners co-brand and subject matter experts publish their own posts. Sales, product, business development, internal comms and the C-suite all now create customer-facing content.
Personalisation and channels multiply this further. Every ABM programme, persona track and sector variant adds adaptations, and each runs across paid social, email, events, webinars, sales enablement and search. One campaign can easily produce hundreds of assets.
With volume no longer a constraint, coherence has become scarce. When every asset starts from a slightly different reading of the brief, the market receives dozens of loosely related messages, when what builds memory is one message delivered dozens of times.
What a big idea and a theme do
A big idea is the single organising thought a campaign exists to prove. At Velo we build it from three truths: something true about the brand, the product and the customer. It should fit in one sentence and be substantial enough to support a year of activity.
A theme is how that idea shows up: the line, the visual system, the tone, the recurring creative device and the language. The big idea is what people remember; the theme is what they recognise. Together they let an ad, a sales deck, an event stand and a nurture email look different while clearly making the same argument in a cohesive way.
The science is well established. Robert Zajonc’s mere exposure research showed that repeated exposure increases familiarity and, under the right conditions, preference. In B2B, where the Ehrenberg-Bass Institute and LinkedIn’s B2B Institute suggest only around 5% of buyers are in market at any time, most activity has to build memories buyers can retrieve when a need arises.
One exposure is rarely enough, as people give partial attention and forget. An opportunity to see isn’t the same as attention. There’s also no magic number: the “rule of seven” has no scientific basis . In fact, five to ten or more opportunities to see is a useful planning hypothesis, spaced over weeks and months, but it depends on creative, channel, category and familiarity.
Repetition works best when the idea stays constant, and the executions vary. Frequency creates familiarity, consistency turns it into memory, and memory gets a brand recalled when a buying need appears.
One idea across territories, products and offers, united by the audience
Businesses with several products, regions and micro-offers tend to give each its own messaging. The better organising principle is the audience. Products and offers change; buyers and their problems change far more slowly, so an idea built around the customer’s situation can carry every offer.
That audience is a buying unit. Gartner puts the typical group for a complex B2B purchase at six to ten stakeholders, and Forrester has found more. Each asks a different question. The CFO asks about return and risk, the user about whether it makes their job easier, IT about integration, procurement about justifying the supplier and the sponsor about why this matters now. Tailored messaging answers those questions, but buying groups must reach consensus. Tell finance it’s about cost, IT it’s about simplification and the CEO it’s about transformation, and you’ve given them three reasons to buy and no shared one.
We recommend one shared proposition with role-specific reasons to believe. Take “reduce operational risk without adding complexity”: for the C-suite, protected continuity; for finance, fewer costly incidents; for IT, straightforward governance; for users, less friction. Tailor the relevance and keep the proposition constant. Regional variants localise the proof and examples, and micro-offers become smaller first steps towards the same idea.
An anchor for effective AI use
AI is only as consistent as its starting material. Give ten people the same tool and a vague brief and you get ten slightly different campaigns. Give them a shared set of anchor artefacts and you get variety in execution with consistency in meaning:
- The big idea statement, with the problem it addresses and why it’s true for the brand.
- The value proposition narrative from which decks, web pages and sales copy derive.
- Role-specific reasons to believe and approved proof points for each buying-unit member.
- Product and offer descriptions written in the campaign’s language.
- A common lexicon of words the campaign uses and avoids.
- The creative device, with rules and examples.
Loaded into an AI workspace or prompt library, these mean a salesperson, a regional marketer and an agency copywriter all draw from the same source. Without the anchor, AI accelerates fragmentation. With it, AI scales one consistent message across the organisation.
Why this amplifies effectiveness
A consistent idea makes every exposure count towards the same memory. It also lets people other than the vendor carry the campaign.
CEB (now Gartner)’s The Challenger Customer describes the Mobilizer, someone inside the customer who builds consensus. A campaign succeeds when that person thinks, “Sarah needs to see this.” You’ve then earned an exposure you didn’t pay for, carrying a colleague’s endorsement. B2B content has to be portable: a statistic someone can repeat in a meeting, a one-page business case, a peer customer example, a forwardable executive summary, answers to finance, IT and procurement objections. People can only pass on a message they can hold in their heads, and one clear argument expressed ten ways is far easier to champion than ten disconnected assets.
Recommendation also reduces risk. A poor enterprise decision can consume a six-figure budget and damage a career, so buyers look for reassurance from peers (“companies like us use them”) and colleagues (“our Head of Operations thinks we should look at this”).
This gives marketing control again
Content now comes from everywhere, and approving every asset is impossible. A big idea offers a different kind of control: marketing owns the source, meaning the idea, story, language and rules, and colleagues create freely within that frame.
Governance becomes a simple question: does this express the big idea, use the agreed language and apply the creative device? Briefing speeds up, as new products and regions slot into an existing structure, and measurement becomes meaningful when activity stays consistent long enough to build memory.
It also protects the campaign from the marketing team itself. Marketers tire of a campaign long before most of the market has noticed it. A defined big idea lets teams refresh executions while leaving the core argument alone.
Why a B2B agency is well placed to create it
The idea must work for everyone producing content: in-house marketing, sales, product, regions, partners and every external supplier from the media agency to the PR firm. That’s hard to achieve from inside any one of them.
Internal teams know the business best, but product teams champion their product and regions their market. An agency can sit across all of them and build the idea around the customer, the one thing they share. A specialist B2B agency also understands the buying unit and knows how to turn a strategic truth into a theme that works in a 30-second video, a technical white paper and a sales conversation. Fresh eyes also hear the language the business no longer notices and spot the claims every competitor makes.
The biggest advantage comes afterwards. An agency can own the anchor artefacts, brief every supplier from the same foundation and act as a neutral steward when new products, regions or agencies join. The idea then outlasts reorganisations and team changes, working across internal and external teams alike since it belongs to none of them.
More channels, more authors, more personalisation and more AI make B2B marketing easier to produce and harder to remember. The businesses that benefit will decide early what they want the whole buying unit to remember, then make sure every asset and every colleague says it. The big idea and associated theme is more important than ever.
