Every quarter, the same numbers walk into the same slide decks. Fifty-seven percent of the buying journey happens before sales gets a call. The buying committee has grown to seven, or ten, or twenty.
Buyers spend only 17 percent of their time with suppliers. Ninety-five percent of your market is not in market. The figures have become furniture: nobody asks where they came from, because everybody has already seen them somewhere else.
I went and checked the receipts. The short version: the direction of every one of these statistics is real, the precision is mostly fiction, and three of them have been revised or walked back by the very organizations that made them famous. If your demand strategy quotes them to the decimal, it is anchored to research older than some of the martech stack running it.
Where Does the 57% B2B Buying Journey Stat Come From?
Start with the most famous number in B2B. The 57 percent figure comes from a study run by CEB’s Marketing Leadership Council with Google in 2011, updated in 2013, based on roughly 1,500 decision makers and influencers across 22 large companies. That is a real study, and its central insight, that buyers do serious homework before engaging sellers, has aged well.
Everything else about the way the number gets used has aged badly. It was an average that concealed enormous variance across categories and deal types, and the analysts who popularized it spent years afterward explaining what it did not mean: not that sales is locked out of the first half of the journey, and not that the number applies to your category. SiriusDecisions publicly pushed back on the fatalistic reading, and even LinkedIn’s own sales blog eventually filed the stat under myths that waste sellers’ time. A 2011 average from 22 companies is a historical data point. It is not a description of your pipeline in 2026.
How Big Is the B2B Buying Committee, and What Does the 17% Stat Really Mean?
Next, the incredible growing buying committee. In the mid-2010s, CEB research put the average B2B buying group at 5.4 people, a figure that climbed to 6.8 within two years, and Gartner’s standard formulation today is six to ten decision makers for a complex solution, with larger enterprise deals often involving more. Notice two things.
First, the publisher itself has revised the number upward repeatedly, which tells you it was never a constant, it was a snapshot of a moving trend. Second, the range matters more than the midpoint: a six-person committee and a sixteen-person committee are different sales motions, different content problems, and different measurement problems. Averaging them produces a number that describes neither. The honest use of this research is directional: buying groups grow, involvement spreads across functions, and any go-to-market model built around a single economic buyer is planning for a market that no longer exists.
Then there is the 17 percent, which is the most instructive case of the lot, because the correction comes from inside the original research. Gartner’s buying journey work found that buyers spend about 17 percent of their total purchase process interacting with suppliers. The part that gets left off the slide is the qualifier: that 17 percent is shared across all suppliers under consideration.
Run the arithmetic with three or four competing vendors and any individual sales team is getting something like five or six percent of the buyer’s attention. Quoted in full, the statistic is a bracing argument for making every interaction count and for investing in the channels buyers use when you are not in the room. Quoted in half, it is merely a smaller number than the last one.
What Is the 95:5 Rule in B2B Marketing?
The newest member of the deck is the 95:5 rule, published in 2021 by Professor John Dawes of the Ehrenberg-Bass Institute through LinkedIn’s B2B Institute: at any given time, up to 95 percent of your potential buyers are not in market. Unlike the others, this one comes with its derivation attached, and the derivation is the point. Companies change providers of a given service roughly every five years, so about 20 percent are in market in a year, roughly five percent in a quarter.
Dawes himself presents it as a strategic heuristic, wording included, not a measured constant: the phrase is up to 95 percent. Used as intended, it reframes how you value advertising to people who will not buy this quarter. Used as a measurement, it is a rounding exercise wearing a lab coat.
How Should Demand Teams Use B2B Buying Research?
So what should a demand team actually do with all this? Three habits, none of which require a budget line.
Date every number you present. If the slide says 57 percent, it should also say 2011, and the room should be allowed to react to that. A statistic with its date attached is evidence; without it, it is decor. The same goes for sample and scope: 1,500 respondents across 22 enterprises is a very specific lens, and knowing that changes how far you generalize.
Use industry research for direction, and your own funnel for decimals. The published numbers agree on the trends: more stakeholders, more independent research, less seller access, long out-of-market periods. Those trends should shape strategy. But the precise values that matter, how many people touch your deals, where your buyers actually spend their time, what share of your accounts are in motion this quarter, are all measurable in your own CRM and analytics, at your sample size of one company, which happens to be the only sample that predicts your business.
Treat statistical hygiene as a maturity marker. The organizations that quote 2011 numbers unlabeled are, in my experience, the same ones making channel decisions on instinct dressed as data. The discipline of asking when was this collected, who was sampled, and what exactly was measured is cheap, transferable, and quietly diagnostic: teams that apply it to conference-slide statistics start applying it to their own dashboards, and that is where the compounding begins.
Are B2B Buying Group Statistics Still Worth Citing?
None of this is an argument against the researchers. CEB, Gartner, Forrester and Ehrenberg-Bass did the field a service, and their core findings hold. The argument is against the way their numbers calcified into scripture on the way from the study to the slide.
B2B has spent a decade telling buyers to do their homework on vendors. The numbers we quote about those buyers deserve the same treatment.
