Gen Z hasn’t rewritten B2B buying; the buying environment has changed

Nadia Cameron’s piece in Mi3 on how younger B2B buyers are placing greater weight on trust, peer validation and expert voices draws on new LinkedIn research and commentary from leaders at Built, MUFG, and Humanforce. The most interesting part is not the suggestion that Gen Z has rewritten the rules of B2B buying, but the evidence that the environment in which B2B buyers form judgements has changed.

Trust, recommendations, expertise and peer influence have always mattered in B2B, particularly where purchases are complex, involve multiple stakeholders and carry organisational risk. It is not whether these factors matter, but whether buyers now encounter and evaluate them differently.

The buying environment has changed more than human nature.

LinkedIn’s research shows that millennials and Gen Z now hold a significant share of leadership roles, but the behavioural claims need to be interpreted with caution. Much of the research reflects marketers’ perceptions of younger buyers rather than direct observation of buyer behaviour, which makes the findings useful as an indication of how marketers see the market changing, but not sufficient evidence that the fundamentals of B2B decision-making have been rewritten.

What has changed is access to information; buyers can now research suppliers earlier, more independently and across a wider range of sources. They may encounter executives on podcasts, specialists on LinkedIn, customers in case studies, and, increasingly, AI-generated summaries before they ever speak to sales. Cameron Partridge observes, the first sales meeting is increasingly not the first human impression. The underlying human judgement may be familiar, but the infrastructure through which that judgement is formed has changed substantially.

Visibility, credibility and confidence are different jobs

This changes the role of marketing because visibility, credibility and confidence address different parts of the buying process. Visibility helps an organisation gain consideration; credibility gives buyers reasons to believe its claims; and evidence and relevant expertise help reduce uncertainty enough for buyers to proceed.

This connects directly to the argument in B2B Buyers Don’t Need More Trust. They Need Less Uncertainty. The more practical question is not whether buyers trust a supplier in some abstract sense, but what they remain uncertain about and what evidence would help resolve that uncertainty. Cameron’s distinction between visibility and credibility is useful in this respect because you need enough visibility to get considered and enough credibility to move the decision forward.

Marketers need to diagnose the problem accurately. If buyers do not know an organisation exists, the problem is awareness. If they know the organisation but do not believe its claims, the problem is credibility. If they believe the organisation is capable but still perceive too much implementation, commercial or organisational risk, the problem is uncertainty.

Expert voices only matter when they contain expertise

The shift towards “people-led” marketing also needs qualification, because adding more executives and subject-matter experts to LinkedIn does not automatically confer credibility. The value lies in whether the person has relevant knowledge, experience or evidence that helps the buyer make a better judgement.

As discussed in Find the voices B2B buyers trust, the appropriate source depends on the question being answered. In some cases, that may be the CEO, while in others it may be a technical specialist, product leader, practitioner or customer. Seniority does not in itself determine credibility, and a visible human presence is not evidence unless the person can contribute something useful to the buyer’s assessment.

The more useful interpretation of the move from brand-led to people-led communication is therefore not that organisations should make more people visible, but that they should identify the people best placed to address specific buyer questions with relevant expertise, experience and proof.

AI makes evidence relatively more valuable

AI makes this distinction more important because it is becoming increasingly easy to produce polished, competent-looking content. As the cost of producing claims falls, presentation becomes a weaker signal of expertise, while judgement, originality, evidence, reputation and demonstrated experience become relatively more valuable.

This supports the broader evidence-led content principle we are applying at Human Digital, which is that expertise should be demonstrated through substantive analysis, documented experience and credible evidence rather than asserted through tone or production quality alone. The scarce resource is therefore not content itself, nor is it simply human authorship. It is credible knowledge grounded in actual experience, evidence and judgment.

Marketing can make trust visible, but it cannot manufacture it

There is also an important organisational implication in the article. Marketing can make expertise and evidence visible, but it cannot manufacture trust independently of the broader customer experience.

Wendy Mak makes this point when she grounds trust in whether organisations respond properly, resolve problems, and deliver on their promises. Trust is ultimately an organisational outcome rather than a communications tactic. Marketing can shape expectations and provide evidence, but sales, onboarding, delivery, service and account management determine whether those expectations are subsequently confirmed or undermined.

B2B buying has not suddenly become human

Gen Z is not rewriting the B2B playbook. B2B buying has always been human, but buyers can now access more information, encounter more credible voices before speaking to sales, and compare organisational claims against a wider body of evidence.

For marketers, the implication is to make relevant expertise easier to discover, provide evidence that addresses specific areas of buyer uncertainty, and ensure the experience delivered by the organisation supports the promises made before the sale. Trust is the outcome of that process, while expertise and evidence are among the mechanisms that reduce uncertainty.
