How B2B buying groups research vendors on LinkedIn

Most B2B founders think about sales as a conversation between themselves and a buyer. One person, one deal. The proposal goes to one name, the call is with one person, and the decision feels like it rests with one individual.

That picture was never entirely accurate. It is less accurate now than it has ever been.

B2B purchasing decisions are group decisions. They always have been, but the size of those groups has grown significantly, and the way those groups research vendors has changed in ways that most founders have not fully adjusted to. The research phase, the part that happens before a vendor is contacted, is now conducted by multiple people across multiple channels, often simultaneously, and increasingly with the help of AI.

If you are not visible to that group during that phase, you are not on the shortlist. And if you are not on the shortlist before formal evaluation begins, you are statistically unlikely to win the deal.

The size of the buying group has changed

The 6sense 2025 B2B Buyer Experience Report is one of the most useful pieces of research for any founder thinking about pipeline. It tracks how buying groups actually behave, not how salespeople want them to behave, but what they genuinely do.

One of the most striking findings is the scale of the groups involved. B2B buying decisions now typically involve more than 10 people. That includes the primary decision-maker, technical evaluators, financial approvers, legal or procurement contacts, and end users who will live with the outcome. Each of these people has a view, and many of them research independently before any group conversation takes place.

What this means in practice is that your LinkedIn presence is not being evaluated by one person. It is being evaluated by multiple people with different priorities, different questions, and different levels of familiarity with your market. The technical evaluator wants to see that you understand the problem at a granular level. The financial approver wants to see that you are credible and established. The end users want to see that you understand their world.

A consistent LinkedIn content presence, one that covers the full range of your expertise rather than a single message, is far better positioned to reach a diverse group than any single sales conversation could be.

What buying groups actually do on LinkedIn

The 6sense data shows that 79% of contact is now initiated by buyers, not vendors. Buyers reach out when they are ready. What that means is that the vendor's job during the research phase is not to reach out. It is to be findable, credible, and visible when the buyer is looking.

On LinkedIn specifically, buying group members are doing several things during their independent research phase.

Searching for the founder or CEO by name

When a buying group member gets a referral or finds a company through a search, the first thing many of them do is look up the founder. They search the name, pull up the LinkedIn profile, and read the most recent posts. This is the moment where a dormant profile, one with no recent content, a generic headline, and no visible point of view, fails to build on whatever positive impression started the research.

A profile that shows consistent, specific, market-aware content tells a different story. It signals that this person is engaged with their sector, has genuine expertise, and is worth speaking to. That signal is being registered across multiple buying group members simultaneously, not just by one person.

Reading posts over time

LinkedIn's algorithm surfaces content to people who have previously engaged with a profile. A buying group member who viewed a founder's profile three weeks ago will start seeing their posts in their feed. This is one of the most underappreciated mechanics of LinkedIn as a pipeline channel.

The implication is that LinkedIn thought leadership operates differently to most marketing. A single great post reaches people once. A consistent content programme reaches the same people repeatedly, building familiarity over weeks and months. By the time a buying group member reaches out, they may have been reading your posts for 60 days without you knowing it.

The Edelman-LinkedIn 2024 B2B Thought Leadership Impact Report found that 73% of buyers say thought leadership is more trustworthy than traditional marketing. That trust is built incrementally, through repeated exposure to specific, genuine content, not through a single impressive piece.

Comparing founders directly on the platform

Buying group members do not research vendors in isolation. They compare. If your company is on a shortlist alongside two competitors, the buying group is reading the LinkedIn profiles of all three founders side by side. They are comparing tone, expertise, consistency, and what each person actually seems to know about the space.

This is the moment where a founder with an active LinkedIn presence has a material advantage over a competitor who does not post. It is not about follower count or viral content. It is about whether there is a visible, credible point of view that can be assessed and compared.

Using AI to shortlist and summarise

This is the most recent and perhaps most significant shift. According to 6sense's 2025 data, 94% of buying groups now use large language models during their research phase. Buyers are asking AI systems to compare vendors, summarise capabilities, and generate shortlists before they have spoken to anyone.

AI systems that generate these summaries draw on publicly available content, including LinkedIn posts, blog articles, and any other indexable material. A founder whose content is well-structured, specific, and regularly updated is more likely to appear in those AI-generated comparisons than one whose digital presence is thin or generic.

This is not a distant future scenario. It is happening in buying processes right now, across professional services, SaaS, and consultancy: the sectors where B2B founders and independent consultants are most likely to be evaluated.

The Day One shortlist problem

The 6sense research points to a dynamic that changes how pipeline should be thought about. Ninety-five per cent of the time, the vendor who wins the deal is already on the buying group's shortlist at the start of formal evaluation. The vendors who are not on that Day One shortlist rarely win, regardless of how strong their pitch is.

The shortlist is not assembled during the formal process. It is assembled during the research phase, the 61% of the buying journey that vendors are typically unaware of. Buyers bring their existing impressions, their remembered content, and their prior familiarity into the formal evaluation. They are confirming a preference, not forming one.

This has a direct implication for LinkedIn. Being on the Day One shortlist requires being visible during the period before formal evaluation begins. That visibility is built through consistent content, not through outreach or pitch decks. The B2B founders who are most consistently present on LinkedIn during the research phase are the ones most likely to be on shortlists they were never told about.

The founders who rely on referrals alone, without a content presence, are only visible to buyers who already have a personal connection to their network. LinkedIn extends that reach to buyers who are researching without a referral, which is increasingly how the first contact with a new provider starts.

What this means for how you need to show up

The practical implication of all of this is that LinkedIn content needs to be built for a group, not for a single reader. That does not mean writing content that tries to appeal to everyone. It means covering the full topical territory around the problems your buyers face, so that different members of a buying group encounter content that is relevant to their specific angle.

A sales leader on the buying committee needs to see that you understand commercial dynamics. A technical evaluator needs to see that you understand implementation. A founder or CEO approving the budget needs to see that you have credibility in the sector. A consistent content programme that moves across these dimensions reaches all of them over time, far more effectively than a single post or a single sales conversation.

Frequency matters here more than perfection. Buying group members are not waiting for your best post. They are forming impressions from the accumulation of what they have seen over weeks. A founder who posts three times a week for six months creates a much richer picture than one who posts a highly polished piece once a month.

The research also underscores the importance of structuring your content for AI discoverability. If 94% of buying groups are using LLMs to research vendors, the content you produce needs to be specific, factual, and clear enough for an AI system to extract and summarise accurately. Generic or vague content is less useful to a buying group member using AI, because there is less for the AI to surface.

The compounding effect

LinkedIn's value as a pipeline channel compounds over time in a way that most marketing channels do not. Each piece of content builds on the last. Each new connection expands the audience for future posts. Each interaction, a comment, a share, an inbound message, generates signal that the algorithm uses to extend reach.

A founder who has been posting consistently for 12 months has a materially different LinkedIn presence to one who has been posting for two months. The research phase that buying groups go through is long. The 6sense data shows the average buying cycle is now 10.1 months. A founder who has been visible throughout that period is in a fundamentally different commercial position than one who only started posting after a pipeline gap appeared.

This is the core argument for treating LinkedIn as a long-term commercial asset rather than a short-term marketing channel. The pipeline it generates is not linear. It is cumulative, and it compounds.
