Your B2B buying group is missing a McCartney, or a Messi

Imagine the Beatles without Paul McCartney. John, George and Ringo are still there, the instruments are still plugged in, and you've still got three incredibly talented musicians. But the sound would be different, the songs would be different, and the history of the band would almost certainly have taken a different direction.

Or Argentina without Messi. The New England Patriots without Tom Brady. Jaws without Chief Brody, or indeed without the great white shark. Actually, that last one would probably have been a considerably less successful film, although it might have saved a few people from developing a lifelong fear of swimming in the sea.

The point is that the whole can be very different when one of its key members is missing.

And yet, in B2B marketing, we still seem remarkably comfortable with the idea that we can identify a handful of people in a target account, put them into a campaign and expect the same outcome as if we'd reached everyone involved in the decision.

We talk about buying groups, buying committees and multiple decision-makers. We know that enterprise purchases rarely come down to one person sitting in an office, reading a brochure and making a decision over their morning coffee. Even relatively straightforward purchases can involve finance, IT, operations, procurement and the people who will actually have to live with whatever gets bought.

We know all this. But how often do we really know who makes up the buying group in the accounts we're targeting?

I was reminded of this by a decision in our own business. We're a company of around 40 people, hardly a multinational with a procurement department that requires its own postcode, and even a decision to change our finance software involved three people: our Finance Director, Technology Director and Operations Director.

Each had a different perspective, different priorities and different questions to answer. Finance needed to understand the financial implications, Technology needed to consider the systems and technical requirements, and Operations needed to think about how it would work in practice. Leave one of those people out of the conversation and you might still get a decision, but you could easily end up with a different decision, a slower process or a rather uncomfortable conversation further down the line.

And that's in a business with 40 employees. Imagine what happens when you're selling a complex technology solution into an organisation with thousands of people, multiple departments and a buying process that can take months or even years.

You might have identified the person who owns the budget, but have you found the person who can veto the project? The person who will influence the technical specification? The person responsible for implementation? The person who will use the product every day and quietly tell their boss that the whole thing is a terrible idea?

They might not all have the same job titles from one organisation to another, and they certainly won't all appear neatly on the same data platform. But they can all have a bearing on whether you win the business.

Missing just one member of the buying group can change the outcome.

Think about the Beatles analogy again. Perhaps you've found John, George and Ringo. You've built your audience, created your messaging and launched your campaign. Everything looks perfectly reasonable in the dashboard. Except you've missed Paul, and perhaps the person who was quietly shaping the direction of the band from behind the scenes in the first place. Your version of the Beatles might still make music, but it isn't necessarily going to sound like the Beatles we know.

In B2B, that missing person might be the Finance Director, the Head of IT, a specialist in information security or a role you hadn't even considered because it doesn't appear in your traditional view of the buying group.

And this is where the data becomes important.

Finding buying group members isn't simply a case of buying a database, uploading a list of target accounts and assuming you've got the full line-up. Platforms such as ZoomInfo and Cognism can be valuable parts of the process, but no single source is likely to give you every relevant person, with the right role, at the right account, at the right time.

We've found considerably greater success by combining first-party data with a mix of third-party sources, each bringing something different to the picture. Your CRM and marketing engagement data might tell you who already has a relationship with your business. A data platform might identify additional contacts. Other specialist sources can help uncover people who are missing, validate what you already know or reveal roles that weren't previously on your radar.

This might include a data platform like the above, but supplemented with other 3rd party data to really make the more complete line up.

The important thing isn't the number of sources you use. It's what each source adds, how well the information fits together and whether the result gives you a more complete view of the people involved in a decision.

For one client targeting the channel, for example, we helped identify missing buying group members across key partners and resellers. It wasn't a case of finding one magic database that contained everybody. It was a combination of five sources, each contributing something to the final picture. The result was a much better opportunity to reach the relevant people across those partner organisations, rather than relying on the contacts already sitting in the client's existing data.

For another client, the discovery was slightly different. We found roles involved in the decision-making process that they hadn't previously recognised as part of the buying group at all. These weren't simply missing names for familiar job titles. They were missing characters in the story, people whose involvement changed the way the client needed to think about reaching and influencing an account.

I suppose that's the equivalent of discovering the Fifth Beatle.

Although, depending on which version of Beatles history you subscribe to, that title has a few contenders. Which rather proves the point: sometimes the question isn't just who's missing from the line-up, but whether you've correctly understood who the line-up actually consists of.

This matters because buying group marketing isn't simply about reaching more people. It is about reaching the right people, understanding their different roles in the decision and giving yourself the best possible chance of being considered by the group as a whole.

There is little point in proudly reporting that you've reached 80% of the contacts in your target accounts if the 20% you're missing includes the people who can stop a deal in its tracks. Equally, there is little value in flooding an account with contacts who have no meaningful role in the decision. More data isn't automatically better data, and a longer contact list doesn't necessarily mean a more complete buying group.

What matters is whether you've found the people who can influence the outcome.

So what should we actually do about it?

I'd start by taking a handful of your highest-priority target accounts and asking a simple question: if one of these businesses were going to buy what we're selling, who would need to be involved in making that decision?

Not just who owns the budget, or who has the job title that looks most relevant in your CRM, but who influences the decision, who evaluates the solution, who has to implement it, who will use it and who can ultimately say no. The answers will vary by product, deal size and organisation, but that is precisely the point. A buying group shouldn't be a generic list of job titles copied from one campaign plan to another.

Then give each account a simple Buying Group Coverage Score out of five. Identify the five roles most relevant to your particular sale:

• Budget owner: who controls or approves the spend?

• Business sponsor: who owns the problem or wants the outcome?

• Technical evaluator: who assesses the technology, security or integration?

• Operational owner: who will implement or manage the solution?

• End-user representative: who will use it and influence adoption?

Award one point for each role where you've identified a relevant person and have reasonable confidence that they're the right contact. No contact, no point. A name that looks plausible but hasn't been validated shouldn't automatically earn one either.

An account scoring five out of five has all five roles identified. One scoring two out of five has some work to do. And an account scoring four out of five might look healthy until you discover that the missing role is the person with the power to veto the purchase.

That's why the score needs one important caveat: not all gaps carry equal weight. Five out of five is a useful indicator of coverage, not a guarantee that you've found every influencer or that the deal will close. If the missing person is a critical decision-maker, that gap matters more than the raw score suggests. Adapt the five roles to the purchase you're selling into rather than treating them as a universal buying committee.

Next, compare that picture with the contacts you actually have. Are you relying too heavily on the people already in your CRM, or on a single third-party data provider? Are there roles you haven't considered at all? For some businesses, the missing person will be an obvious decision-maker. For others, it might be a specialist or internal influencer whose involvement you hadn't previously recognised.

From there, enrich the gaps using a combination of first-party engagement data and relevant third-party sources. Don't assume one platform will give you the complete answer. Use different sources to fill different gaps, validate what you can, and build a more complete picture of the buying group. Then make sure your marketing and sales teams are working from that same picture, rather than each having their own slightly different version of who matters.

Finally, track the score across your priority accounts over time. Are you improving coverage? Which roles are consistently difficult to identify? Which data sources are filling the gaps? And are you reaching the people you've identified, rather than simply adding their names to a database?

Keep coverage and engagement as separate measures. Finding the five relevant people is one job; getting them to engage is another. Combining the two into a single score can hide exactly where your marketing needs to improve.

This isn't about collecting the largest possible database or bombarding everyone in an organisation with the same message. It's about giving yourself a better chance of reaching the people who collectively make the decision, with information and content that reflect their different concerns.

Because the aim isn't simply to get the band on stage. It's to make sure we've got the right people playing the right parts.

And if you're trying to win a major B2B deal, the person you've failed to identify might turn out to be your missing Messi, your missing McCartney or your very own Fifth Beatle.

So here's the challenge: pick ten of your most important target accounts, score each one out of five, and identify the gaps. You'll quickly see whether your supposedly well-covered accounts are actually missing a key member of the band.

You might find that the next improvement in your pipeline doesn't come from reaching more accounts at all. It comes from finding the people you should have been reaching in the accounts you're already targeting.
