The B2B SaaS buyer you picture, one person with one budget and one yes to give, mostly does not exist. In their place is a committee: a shifting group of stakeholders who each get a vote, a veto, or at least a strong opinion they will share at the least convenient moment.
Mystery Demo takes competitors’ real sales demos as a buyer, walking each sales process the way a committee does, and hands back the recordings and a board of what every rep said, showed and quoted. It is never one person on the seller’s side either: an SDR, then an account executive, then a sales engineer, and by the second call a VP nobody had mentioned.
The figures below come from public research, each linked to where it was first published, on how the buying committee is built, who sits on it, and how long it takes to make up its many minds. The short version: the group is large, cross-functional, and has largely decided before a single rep is in the room. If you only keep a handful of these, keep these:
The Buying Committee Is Always Bigger Than One
Ask three research firms how many people are on a B2B buying committee and you get three different numbers, because they are counting three different things. The honest answer is a group, and how big depends on who you count. That count is the number of people a rep has to win over, so it pays to know what each firm counted.
| Research firm | What it counts | Group size |
|---|---|---|
| Gartner, 2025 | Members of the buying group, in a survey of 632 buyers | 5 to 16 people, across up to four functions1 |
| 6sense, 2024 | The average buying group, from 2,509 recent buyers | 11 people4 |
| Forrester, 2026 | Internal stakeholders and outside influencers on a typical decision | 13 internal and 9 external2 |
| Forrester, 2024 | People inside the buying organization | 13 on average3 |
| TrustRadius, 2024 | The size most groups settle at | Two to five people7 |
| Demand Gen Report, 2022 | Buying groups with one to three members | 41% of groups8 |
That spread is not noise. Much of it comes from what each firm counts: Gartner the buying group itself, Forrester the wider network of internal stakeholders and outside advisors, and TrustRadius and Demand Gen Report how groups spread across sizes. The gap between the widest count and the narrowest is the part most vendors never see: the colleagues, consultants, and peers shaping the call from offstage.
Most buyers in big groups do not experience the crowd as a burden. 94% of buyers in groups of six or more report clear benefits, such as broader perspectives and a better chance of securing budget, in Forrester’s 2026 research.2
Not every source says committees are growing, though. Some show them consolidating into smaller groups.
The large counts and the shrinking ones are both true. Group size follows the size of the buyer, as the TrustRadius split shows, and the mix of purchases is tilting toward smaller deals: G2’s 2025 report says multi-year mega-deals are shrinking across every segment.9 6sense adds one more data point: in 2025 buyers weighed 5.1 vendors on average, up from 4.5, yet their buying groups did not grow.10
For anyone studying a competitor, the headline average matters less than the shape of the group around a deal like yours, and that shape only shows up when you watch the whole evaluation, not a single call.
Every Seat on the Committee Wants Something Different
Size is only half the picture. What makes the committee hard to read is that it is cross-functional by design, and the mix tells you who you are really selling to. The buyer who watches the demo is rarely the one who signs the contract.
| Seat | Figure | What it measures |
|---|---|---|
| Procurement | 53%2 | Buying cycles where procurement professionals are decision-makers, engaged from the start (Forrester, 2026) |
| Finance | 46%, up from 31%5 | Software decisions finance took part in (G2, 1,038 decision-makers, June 2026) |
| IT | 47%9 | Software purchase decisions where IT was involved (G2, 2025) |
| Information security | 25%, down from 32%5 | Software decisions security took part in (G2, June 2026) |
| C-suite or CFO | 42%11 | Buyers who name one as ultimately responsible for the purchase (G2, 1,940 decision makers, 2024) |
| VP level or above | 52%7 | Decision-makers holding a VP title or higher (TrustRadius, 2024) |
| Head of AI or CIO | Under 10%9 | Purchase decisions where these newer roles appear (G2, 2025) |
Buyers play overlapping roles, too. Asked what role they played in a recent purchase, buyers in Demand Gen Report’s 2021 survey answered 45% primary decision maker, 29% champion, 26% researcher, 21% end user, and 16% a technical influencer from IT, Legal, or Operations.12
Two figures from the seat table sit in tension. 42% of buyers name a C-suite executive or the CFO as the one ultimately responsible, yet 82% of buyers call the choice always or frequently consensus-based.11 Both are true: someone is ultimately accountable, and that person’s yes is hostage to a consensus they do not fully control.
It is also why one demo is a poor sample of a competitor’s real sales motion. The sales engineer is selling to the end user and the champion in the room, but the real decision comes later, with the VP, the CFO, and a procurement lead who were never on the call you saw.

Finance now holds a veto, too. Nearly half of software buyers had an approved purchase vetoed by the CFO in the past year, in G2’s 2026 survey.5
Formal committees are also spreading. In Demand Gen Report’s 2021 survey, 19% of companies formed a buying committee for the first time, on top of the 49% that already used one.12
They’ve Mostly Decided Before You Hear From Them
The committee does the bulk of its work before any vendor knows it exists. By the time a rep gets a hello, the shortlist is built and ranked.
This is the demand-generation reality behind the committee: most of your future buyers are not even looking yet. Up to 95% of firms are out of the market for many products at any one time, by a rule of thumb from the Ehrenberg-Bass Institute.14 When the 5% do start, they begin with the vendors they already know.
A favorite at first contact is not a signed deal, because two contests run one after the other. Familiarity wins the first, which decides who makes the shortlist, and the live evaluation wins the second, which decides who closes.
Even there the head start holds: the vendor a buyer contacts first wins 8 out of 10 deals, 6sense reports.10 Only this second contest can be watched from outside. The buyer’s research stays private; a rival’s sales process does not, and it can be walked one call and one stakeholder at a time, exactly the way a real committee walks it.
Consensus Is Where Deals Go to Stall
A confirmed favorite still has to clear the committee, and clearing it is where the calendar gets away from everyone. A bigger committee buys more carefully and far more slowly, because more stakeholders means more agendas to reconcile, and a committee is very good at saying no by saying nothing.
| What was measured | Figure | Measured by |
|---|---|---|
| Buyer teams showing unhealthy conflict during the decision | 74%1 | Gartner, 632 buyers, 2025 |
| Purchases that stall during the buying process | 86%3 | Forrester, 2024 |
| Buyers dissatisfied with the provider they chose | 81%3 | Forrester, 2024 |
| Deals lost to buyers who meant to buy and never acted | 40% to 60%6 | 2.5 million recorded sales conversations, 2022 |
| Buyers who stopped making progress more than once | 57%15 | Gartner, 2026 |
| Buyers taking four months or more on a $20,000+ purchase | 49%, up from 41%11 | G2, 2024 |
| Variation in cycle length explained by buying group size | Nearly a quarter10 | 6sense, 2025 |
Agreement pays. Buying groups that reach consensus are 2.5 times more likely to report a high-quality deal, Gartner found.1
The average buying cycle fell to 10.1 months in 2025 from 11.3 the year before.10 6sense says part of that drop comes from its sample, which held more quick physical-goods purchases, though cycles shortened across every major category too.10
On many slow deals the problem is information overload, not laziness. When buyers face too much contradictory information, they are 153% more likely to settle for a smaller, more cautious purchase than they first planned.16 The cost of the committee shows up twice: once as a longer calendar, and again as a shrunk deal.
For competitive research, the stall rate is the opening. If 86% of purchases lose momentum somewhere in the committee, a vendor that removes one friction point its rivals leave in place can pull deals away from rivals who never noticed where they stalled.
Part of that friction sits inside each vendor’s own sales process: the pricing call, the security questions, the follow-up. That part can be watched in full, not as a highlight reel.
The Committee Wants to Buy Without You
Self-service is the default now, and the committee spreads its research across a widening set of channels before anyone dials a rep.
Buyers rarely start cold, so going it alone feels safe, and in Gartner’s 2022 survey the outcomes leaned their way: 65% of self-navigated purchases ended in a high-quality deal, against 24% of rep-led ones.21
Yet buyers do not drop the rep. 69% of B2B buyers prefer to check AI-generated answers with a sales rep, Gartner reported in 2026.22 The same buyers used an average of seven information sources on a recent purchase, and 45% used generative AI along the way.22
The practical read is that the human sale still counts. It just happens later, in front of more people, and only after the committee has tried to do without it. The mode that works, on this evidence, keeps the committee in control, backed by the vendor’s tools and a rep who shows up at the right moment, and the edge goes to competitors who stitch the two together.
How a Rival Sells to Each Seat
Every figure above describes the market, and none of it shows how one rival handles that late, crowded handoff, where a committee’s favorite gets confirmed or overturned. Whether you are defending a category or sizing up one you want to enter, that handoff is what you are really studying. Their internal buying meetings are closed to you; their sales process is not.
Mystery Demo goes through that process the way a committee would, one introduction at a time, and brings back what each rival did:
Below is one competitor’s page from our example board, where the company and every competitor on it are invented. On a real project, each page is built from the recorded calls with that competitor.
Name the rival whose committee deals you keep losing. We will go through its sales process seat by seat as the buyer to show you which story it tells each seat and whether those stories hold together.

Five-to-eight-person committees were down 11% year over year in G2’s 2025 survey, while three-to-four-person groups rose 9%.9 6sense found buying group size flat in 2025, even as buyers weighed more vendors.10
Who sits on a SaaS buying committee in 2026?
46% of software decisions included finance in G2’s June 2026 survey, up from 31%, while security fell to 25%.5 Procurement are decision-makers in 53% of buying cycles2, and IT was involved in 47% of software decisions in 2025.9
Who has final say in a B2B software purchase?
42% of buyers name a C-suite executive or the CFO as ultimately responsible.11 Yet 82% call the choice always or frequently consensus-based.11
How much of the buying journey happens before buyers contact sales?
61% of it, on 6sense’s 2025 measure of when first contact happens, down from 69% a year earlier.10 85% of buyers had largely set their requirements before reaching out.4

What is the 95:5 rule in B2B?
Up to 95% of firms are out of the market for many products at any one time, by the Ehrenberg-Bass Institute’s rule of thumb.14 That is why the vendors a buyer already knows fill the shortlist long before a demo.
How long is the average B2B buying cycle?
10.1 months in 2025, down from 11.3, in 6sense’s survey of nearly 4,000 buyers, partly because its sample held more quick physical-goods purchases.10 For purchases over $20,000, 49% of buyers took four months or more to decide.11
Why do bigger committees take longer to decide?
Nearly a quarter of the variation in buying cycle length comes down to buying group size, the strongest single driver in 6sense’s 2025 study.10 And 74% of buyer teams show unhealthy conflict along the way.1
How often do B2B deals end in no decision?
40% to 60% of deals end lost to buyers who meant to buy and never acted, in a study of 2.5 million recorded sales conversations.6
Do B2B buyers prefer to buy without a salesperson?
67% of B2B buyers say they prefer a rep-free experience in Gartner’s 2026 release.17 Its 2025 release put the figure at 61%.18 Even so, 69% prefer to check AI-generated answers with a sales rep.22
How many channels do B2B buyers use?
Ten or more channels, up from five in 2016, McKinsey found.19 Their first two stops are web search (66%) and vendor websites (45%).20
