LinkedIn has published new research revealing the B2B marketing mistake that costs brands deals at the final stage - and why buying group dynamics, not product capability, now determine which vendors get chosen.

The research, drawing on LinkedIn’s Buyability study conducted with Bain & Company, found that 40% of B2B deals stall because the buying group cannot agree - not because a competitor won. Finance, Legal, and Procurement hold roughly 50% of total decision-making influence yet rarely appear in marketing funnels, and 81% of purchases come from vendors that “almost everyone” in the buying group already knows.

The four buying group outcomes and what drives them

• Champion-driven wins – The deal progresses because one internal advocate pushes it through. These wins are fragile: if the champion leaves, changes role or loses internal influence, the deal collapses. Brands that rely on single-champion relationships are building on unstable foundations.
• Consensus wins – The full buying group aligns around the vendor. These deals close faster, at higher contract values, and are significantly more likely to renew. Brands that reach the whole buying group - not just the recommending function - win more and retain more.
• Committee stalls – The deal gets stuck in internal disagreement. The buying group cannot align, objections multiply, and the vendor loses momentum without ever losing on product. This is the most common reason deals are lost and the least visible one in CRM data.
• Silent losses – The deal dies without a clear decision. No formal rejection, no feedback, no next steps. The buying group didn't reach a decision, and the vendor wasn't clear on the reasons. These make up a disproportionate share of pipeline leakage.

What separates the vendors who get chosen

• Vendors are 20 times more likely to be chosen when the entire buying group knows and trusts the brand at the start of the process.
• Buyers are 3 times more likely to choose a vendor heavily recommended by peers or customers over one that promises a better product or lower price.
• The number one emotional job buyers need to complete before committing is: “I felt I could defend the decision even if it went wrong” - outranking confidence in the product itself.
• Three of the top five decision drivers relate to group dynamics rather than product capability.

What marketers should do differently

• Map the full buying group – Identify every stakeholder with influence over the decision, including Finance, Legal and Procurement, and ensure brand and content reach them before a deal is in play.
• Build peer advocacy deliberately – Customer stories, case studies and peer recommendations should be prioritised and distributed to the right audiences, not just used as bottom-of-funnel assets.
• Make risk the enemy – FOMU (Fear of Messing Up) consistently outweighs FOMO. Marketing should lead with proof of success at companies like the buyer’s, not impressive-sounding features.
• Invest in pre-deal awareness – Brands that are known to the full buying group before a formal RFP begins win at a significantly higher rate. Awareness is not a vanity metric; it is a deal-closing mechanism.
