Every established B2B brand we speak to has a go-to-market strategy built around a tier-one buyer persona. The CFO, the CTO, the General Counsel, the Head of Operations. A senior decision-maker, neatly defined, with a job title, a budget range, a list of pain points, and a preferred content format. That persona sits at the top of every campaign brief, every ABM target list, every quarterly business review.

There is one problem. That persona has almost certainly never personally searched for, evaluated, or shortlisted a single supplier in your category in their working life.

This is the quiet truth that the standard B2B playbook keeps avoiding. At brands turning over £50m and above, the senior buyer named at the top of your persona deck is not the person finding you. They are not scrolling LinkedIn for vendors at eleven o'clock at night. They are not reading your gated whitepaper. They are not in the Slack community where their team is asking peers for recommendations. They are running a function, sitting in board meetings, and delegating. The person actually doing the work of finding, filtering, and recommending suppliers is someone five to ten years more junior, on a fraction of the salary, with a different set of behaviours, a different media diet, and a completely different relationship with your category.

If your marketing is only built to reach the senior buyer, you are not reaching the market. You are reaching the slide.

How shortlisting actually works inside a £50m+ business

Picture the real journey. A senior leader decides the current arrangement is not working. The CFO wants a new spend management platform. The General Counsel wants to replace their contract lifecycle tool. The Head of People wants to consolidate three HR systems into one. They want options. They turn to their team. "Can you pull together a shortlist of three or four we should look at?"

The brief is loose. The deadline is short. The person handed the task is a Finance Operations Manager, a Legal Operations Lead, a Senior People Partner. They have a day, maybe two, to come back with names.

What do they actually do? They do not start on Gartner. They go where their peers are. The Legal Operations Lead checks the CLOC community Slack, looks at who Above the Law has been covering, and posts in a private legal ops WhatsApp group. The Finance Operations Manager checks the Modern CFO Slack, reads what Pavilion members are recommending, and scrolls G2 reviews with a heavy dose of scepticism. The Senior People Partner checks the People Geeks community, looks at who is speaking at HR Tech, and asks their network on LinkedIn.

Then they ask ChatGPT. "Best contract lifecycle management platforms for in-house legal teams at mid-market UK companies." "Recommended spend management tools for finance teams between £50m and £200m turnover." Twenty-three-word prompts, structured questions, specific constraints. They take the AI's shortlist and cross-reference it with the human one.

By the time that combined shortlist hits the senior leader's inbox, the real selection has already happened. The senior buyer is not evaluating the entire market. They are evaluating three or four names chosen by someone the persona deck does not even acknowledge exists.

This is how decisions actually get made at established brands. The brands that get on that shortlist are the ones that have done the work to be visible, credible, and recommendable to that person, not just the person at the top of the org chart.

The playbook problem

The other half of the problem is the playbook itself. If you are running a £50m+ B2B brand, the framework being executed by your team or your agency will look familiar. Tier-one persona at the top. Awareness, consideration, decision funnel. A gated whitepaper per quarter. An MQL target. An ABM list of 200 named accounts. Intent data from 6sense or Bombora. A LinkedIn thought-leadership push from the CEO. An SDR cadence of seven touches over fourteen days. A nurture sequence in HubSpot or Marketo. A presence at the obvious industry events.

It is not wrong. It is just universal.

Every brand in your category is running variations of the same model with similar budgets and similar tools. The result is a consideration set in which everyone looks broadly the same. The same case study format. The same "we deliver X% efficiency gains" headline. The same LinkedIn carousel template. The same gated ROI calculator. The same SDR opening line landing in the same inboxes.

The clearest sign this is happening is when growth plateaus despite increasing spend. Cost per MQL creeps up. SDR-booked meetings get harder to forecast. Win rates soften, particularly at the top of the funnel where the buyer is comparing three vendors that all look interchangeable on paper. Leadership starts asking whether the team is still delivering, when the real question is whether the approach itself is still differentiated.

Playbooks are not the answer to a saturated category. In a saturated category, the playbook is the problem.

The ceiling that T1-only thinking builds

Even when the persona work is sharp and the playbook is well executed, focusing exclusively on the senior buyer creates a ceiling.

A typical enterprise software decision at a £50m+ business now touches between six and ten people. The economic buyer. The function lead. An IT security reviewer who wants to see your SOC 2 Type II report, your penetration test summary, your data residency arrangements, and your sub-processor list. A procurement officer who cares about contract length, auto-renewal terms, pricing model, and reference customers in their sector. A legal reviewer who needs your DPA and a clean MSA. A finance reviewer building the ROI model. Sometimes IT operations checking integration depth with your existing stack. Sometimes a board sponsor needing a one-page summary.

Each of these people has influence. Each carries unspoken veto power. And almost none of them match the T1 persona description.

If your marketing is invisible to the security reviewer, your deal stalls in technical due diligence even after the function lead has championed you. If your procurement story is weak, you lose on terms after winning on capability. If your finance story is thin, your champion cannot build the business case internally and the deal dies in the budget cycle. The senior persona on your deck can push hard for you, and the deal can still die in three other rooms you never marketed into.

This is not about lowering your standards or chasing a less qualified audience. It is about recognising that the buying committee is the audience, not the buyer on the slide. The brands that grow fastest in established B2B categories are the ones who have made themselves visible, intelligible, and credible to every person likely to be in the room when the decision gets made.

What casting a wider net actually looks like

The standard agency response to "we want a wider approach" is to add another persona to the deck and another channel to the plan. More personas, more content, more cost, same underlying logic. That is not what wider means.

Wider means being present in the surfaces your buying committee actually uses, which is rarely the surfaces your media plan is currently funded against. It means a sponsored placement in the niche newsletter your customer's Head of Legal Operations reads on a Tuesday morning, not another LinkedIn carousel. It means earning a citation in ChatGPT's answer when someone asks for vendor recommendations in your category, which requires structured data, citable content, and authority signals across the open web, not another gated PDF. It means being the brand the host of a small, well-regarded category podcast wants on as a guest, not the brand sponsoring the loudest conference of the year.

Wider also means investing in proof that survives scrutiny at every layer of the committee. Named case studies with quantified outcomes for the function lead. A trust centre with SOC 2 Type II, ISO 27001, and a current pen test summary for the security reviewer. A clear pricing page, or at the very least, a defensible answer when procurement asks why there isn't one, for the procurement officer. A pre-built ROI calculator or financial model for the finance reviewer. Reference customers willing to take a call, in the right sector, at the right size. The person assembling the shortlist will be defending their work to their boss. They will not put your name forward if they cannot defend you on every layer.

And wider means treating messaging as a system, not a script. The CFO needs a commercial-impact story framed around margin, working capital, and risk. The Head of Finance Ops needs a capability-and-integration story framed around their existing stack and their team's day-to-day workflow. The security reviewer needs a technical brief framed around their controls framework. None of these audiences should be ignored, and none of them should be served the same content. Casting a wider net does not mean diluting the message. It means building a system in which the right argument reaches the right person in the right place, without losing the coherence of the brand underneath.

The brands doing this well are not adding more channels. They are adding the right channels and reallocating budget from the saturated ones. Less spend on LinkedIn sponsored posts that everyone in the category is already buying. More spend on category podcast sponsorships, original research nobody else in the space has published, presence in private peer communities, and the structured data work that gets you cited in AI-generated answers.

Empowering the internal team

Here is the part that does not get said often enough. The people most aware that the standard approach is no longer working are the internal marketing and growth teams running it. They see the diminishing returns first. They feel the gap between what the playbook promises and what the pipeline actually delivers. They are often the ones being asked to defend a strategy they did not design and increasingly do not believe in.

If you are running marketing or growth at an established B2B brand and recognising any of this, the most useful thing you can do is question the brief, not the budget. A larger budget poured into a tired approach does not solve the problem. A sharper, wider, more honest approach with the same budget often does.

The questions worth raising internally are not abstract ones. When we last won a flagship logo, who actually brought our name into the shortlist conversation, and how did they find us? When we last lost a deal late in the process, which member of the buying committee blocked it, and what would we have needed to give them to win? Are we showing up in AI-generated answers when someone asks for recommendations in our category? Do we know which Slack communities, newsletters, and podcasts our buyers' teams actually use, and are we present there in any meaningful way? When did we last commission original research that gave us something the rest of the category could not say?

These are answerable questions. They tend to surface the gap between the strategy on paper and the reality on the ground, and they tend to be more persuasive in a board conversation than another quarter of channel attribution charts.

That conversation is easier to have when you are not the only person in the room with the argument. Bringing in a partner whose job is to challenge the orthodoxy, map the real decision journey, and design a system that reaches the actual buying committee, not just the persona on the slide, gives the internal team something the standard agency relationship does not. It gives them air cover. It gives them a different perspective with commercial credibility behind it. And it gives them a way to make the case for a sharper strategy without having to fight the case alone.

The simple version

The persona on your strategy deck has never bought anything from you. The person who has, or the person about to, looks different, behaves differently, sits two or three layers below the named buyer, and is currently being ignored by a marketing approach built for someone else.

Established B2B brands at £50m and above are not being held back by execution. The execution is usually fine. They are being held back by an industry-wide playbook that no longer differentiates, a persona model that no longer reflects how decisions actually get made, and a media plan that funds the surfaces everyone else is already buying.

Casting a wider net is not about reaching everyone. It is about reaching the people who actually shortlist you, the people who can veto your deal in due diligence, and the people whose recommendation gets your name into the room. And it is about giving your internal team the strategy and the air cover they need to break out of the standard cycle.

That is the work worth doing. And it is the work most likely to move the needle in 2026 and beyond.
