The buying group was 22 people. How many were in your room?

Forrester's 2026 State of Business Buying puts a number on something sales teams have felt for years. A typical B2B buying decision now involves 13 internal stakeholders and 9 external influencers (Forrester, 2026). That is 22 people with a say. Procurement alone sits among the decision-makers in 53% of buying cycles.

Two years earlier, Forrester's figure was 13 people in total (Forrester, 2024). Other counts run lower. 6sense, a vendor, put the average buying group at 11 members in 2024 and at 10 or more in 2025 (6sense, 2024; 6sense, 2025). The methods differ, so the figures are not a trend line. They agree on the point that matters: a deal is decided by a group, and the group is large.

Now consider the last executive dinner your team hosted. The guest list was probably under 20. Hosted events of that size are where B2B budgets are heading: 63% of organizations plan to run more of them in the next year (Forrester, 2026). The question worth asking afterward is how those seats were spread across buying groups, and how deep into each group they reached.

What tracking sees, and what it misses

Dreamdata, an attribution vendor, found that the average tracked B2B buyer journey involves 6.8 buyer stakeholders (Dreamdata, 2025). That figure comes from what its tracking can observe. Forrester's comes from asking buyers who was involved. The two are not measuring the same thing, and the space between 6.8 visible people and 22 involved ones is a fair description of where event teams operate.

Hosted events are one of the few places a vendor meets the people who never fill out a form. The finance lead who came along because a colleague asked. The procurement manager. The engineer who will run the implementation and has quiet veto power.

Those are exactly the people contact-level measurement struggles to credit.

Why lead scoring misses it

Standard lead scoring works on individuals. Each person accrues points for actions: an email click, a webinar, an event attendance. When one person crosses a threshold, they become a marketing qualified lead and get routed to sales.

Run a hosted event program through that model and it breaks in a predictable way. Three people from the same account attend three different dinners across two quarters. Each gets a modest bump. None crosses the threshold. The account is plainly warming, and the model has no way to add the three together. Guests who were never in the CRM contribute nothing at all.

There is evidence that counting the group pays off. In a Forrester client story, Palo Alto Networks found opportunities with multiple contacts attached were 8 times more likely to advance than single-contact opportunities, and win rates rose 17% after the company moved from MQLs to buying groups (Forrester client story, undated). One company's experience is not a benchmark. It is consistent with broader research. Gartner found buying groups that reach consensus are 2.5 times more likely to report a high-quality deal, and that content aimed at the whole buying group raises consensus by 20%, while content aimed at individuals lowers it by 59% (Gartner, 2025).

"Messages tailored to the buying group or organization foster understanding and consensus, but individual-level content can lead to confirmation bias," said Delainey Kirkwood, a principal in Gartner's sales research practice (Gartner, 2025).

A dinner is a message to a buying group. Freeman, which produces events, found 68% of attendees say hands-on experiences at events help stakeholders reach consensus (Freeman, 2025).

What account coverage looks like

Account coverage asks a simpler question than attribution. It does not claim the event caused anything. It counts who was there, grouped by account, and lines that up against the pipeline.

After each event, three numbers:

• Accounts represented. Distinct companies in the room, and how many were on the target list.
• Open opportunities with a contact present. For each, which contacts on the opportunity attended.
• New people from target accounts. Attendees who were not in the CRM before the event.

Across the program, one more: for your 25 most important open opportunities, how many distinct people from each account have attended any hosted event in the past year, and which functions they represent.

Picture two hypothetical dinners of 18 guests. The first draws 18 accounts, one person each, and three of those accounts have open opportunities. The second draws nine accounts, two people each, six with open opportunities, and in four of those the second guest was someone the account executive had never met. Lead scoring sees 18 contacts in both cases. Coverage sees two very different evenings.

That changes how invitations work. Instead of asking only the champion, ask the champion to bring a colleague from finance or procurement. Instead of filling empty seats with whoever accepts, fill them with the second and third person from accounts already in play. Seniority helps with turnout too: Clutch Events, a vendor, found directors and above attend hosted events at a 62% rate (Clutch Events, 2026).

Closing the measurement gap

Field marketers are caught in the middle of this. Forrester found 79% of field marketers are responsible for ABM strategy, while 73% are measured on pipeline or revenue influenced (Forrester, 2025). Account coverage connects the two. It is an account-level measure that maps directly onto open opportunities, which is what the pipeline number is made of.

This is the problem Socially was built around. It syncs event attendance against HubSpot or Salesforce, shows which open opportunities had contacts in the room, flags attendees who are not in the CRM yet, and tiers contacts by their real attendance behavior across events. The numbers are counts over your own records, not modeled estimates.

The timing makes this more pressing. 6sense found buyers make first contact with sellers 61% of the way through the buyer journey on average, and 94% rank their vendor shortlist before contacting anyone (6sense, 2025). Most of a buying group forms its view before a seller hears from it. A hosted event is one of the few chances to meet more than one or two of those people early.

Next quarter's event report could lead with a single number: of the open opportunities that matter most, how many had more than one person in the room.
