Is Matchmaking Worth It for a Small B2B Event? Four Tests and the Maths

Ninety registrations, one afternoon, one room. Your managing director looks at the quote for matchmaking software and asks the obvious question: do we really need this for an event this size? It is a fair question. Most matchmaking advice is written for trade shows with thousands of buyers, and the vendor pages that mention small events rarely say where “small” begins or where matchmaking stops making sense.

Headcount alone does not tell you whether matchmaking is worthwhile. Matchmaking is a selection tool: it decides which of all possible meetings actually happen. At a small event, its value depends on the number of relevant contacts and the time available to meet them. Participants need more relevant counterparts than meeting slots, otherwise a simple rotation does the job. And they need enough relevant counterparts to build a meeting schedule that makes the trip worthwhile, otherwise you are better off making the introductions yourself. This guide gives you four tests, a worked example with costs, and alternative formats for events with different needs.

The short answer

Matchmaking is worth it for a small B2B event when three conditions hold at the same time:

• There is a clear need for specific participant groups to meet: buyers and suppliers, members and service partners, founders and investors.
• At least one side is too large for everyone to meet everyone in the time you have.
• Each participant has enough relevant counterparts to fill at least three meetings. That is our rule of thumb, and the calculation behind it follows below.

If the first condition fails, run topic tables or open networking. If the second fails, run a rotation. If the third fails, recruitment needs attention before you invest in software.

Why small events need more structure, not less

Small groups can seem easy to leave to informal networking. In a room of 80 people, surely everyone finds the right person over coffee?

Research on networking events suggests otherwise. Paul Ingram and Michael Morris of Columbia Business School tracked about 100 executives at an after-work mixer with electronic name tags that registered every face-to-face encounter. Before the event, 95 per cent said they wanted to meet new people. On the night, the average guest had 14 encounters, and about half of them were with people they already knew (Ingram and Morris, Administrative Science Quarterly, 2007).

That matters more for small events than for large ones. A regional association day or a chamber supplier forum is often a community. Many participants have met before, and the familiar face at the coffee table is always the easiest conversation. A structured format can help newcomers and suppliers join conversations beyond those familiar circles.

The trend data points the same way, with a caveat. RainFocus, an event platform provider, reported in its mid-year 2026 benchmark that attendance at smaller events rose 6.4 per cent year on year, while participation in scheduled meetings at those events jumped 69 per cent (RainFocus via Skift Meetings, September 2026). These are vendor figures, and the report does not define “smaller”. Still, the direction is clear: people come to small events to meet someone specific.

Small formats are not going away either. In the Amex GBT Global Meetings and Events Forecast 2026, 38 per cent of 601 meeting professionals expected to hold more small and simple meetings in 2026, and another 50 per cent expected the same number. So the question your managing director asked will come up again next year.

Four tests to guide the decision

Structure helps. But structure does not automatically mean matchmaking software. Four questions, asked in this order, tell you which kind of structure your event needs.

Test 1: who needs to meet whom?

Matchmaking works best when participant groups have complementary needs or clear meeting goals. A procurement day where member companies meet suppliers has one. So does an investor evening where founders want time with a handful of funds. A members’ breakfast where everyone is a peer usually does not. There, people want conversations around a topic, not a diary, and topic-based roundtables do that job better.

Test 2: can everyone meet everyone anyway?

Start with your slot count: divide the length of the meeting block by the combined duration of a meeting and its changeover. A two-hour block with 15-minute meetings and five minutes to change tables gives you six slots.

If both sides are no larger than the number of slots, nobody has to choose. Ten buyers and twelve suppliers in an hour of five-minute rounds, changeover included, is twelve rounds: every supplier meets every buyer and sits out two rounds. That is a rotation, not matchmaking, and our guide to speed networking at B2B events has the timing maths. Software adds little here.

Once one side outgrows the slot count, somebody has to decide who meets whom. That is the moment matchmaking starts to earn its place.

Test 3: does each participant have enough relevant counterparts?

Next, estimate how many potential counterparts are relevant to each participant. Relevant counterparts are the size of the other side multiplied by the share that actually fits. Two or three category questions at registration are enough to count this before you buy anything.

Our rule of thumb is at least three meetings per participant. It is an editorial guideline rather than a research finding. In a block with six slots, three meetings fill half the diary. Below that, the meeting block has more gaps than meetings, and a supplier left waiting at an empty table may question whether to return. Not every relevant pair becomes a meeting either, because both sides have to agree. If you have no data of your own, assume about half do. Then three meetings need about six relevant counterparts per participant.

There is one more limit. If one side is much smaller, its diaries cap the total, however relevant everyone is. How many sellers a buyer pool can carry is a question of ratio, and we work it through step by step in the right buyer-to-seller ratio for a B2B matchmaking event.

Test 4: could you broker the meetings by hand?

If an event passes the first three tests, the last question is workload. Total meetings are participants multiplied by meetings each, divided by two, because every meeting has two people in it.

Assume ten minutes of organiser time per hand-brokered meeting: finding the fit, two emails, a slot, a reminder. That is our working assumption, so replace it with your own. Forty participants with three meetings each make 60 meetings, or about ten hours. One person can do that over two weeks, and personal introductions often land better than any notification. A hundred and twenty participants with five meetings each make 300 meetings, or about 50 hours. At that scale, each cancellation can create a substantial rescheduling task.

Include that coordination time when comparing manual scheduling with software.

A worked example: 90 people, one afternoon

Here is how the four tests play out for the event from the opening, with assumptions you can replace with your own.

• A regional industry association runs a procurement day: 30 buyers from member companies and 60 suppliers.
• The meeting block runs from 13:30 to 16:30. With 20-minute meetings and five minutes to change tables, that gives seven slots.
• Registration shows that each supplier fits about nine of the 30 buyers.

Test 1 passes: there are two sides with clear goals. Test 2 fails for the rotation, because both sides are larger than seven, so someone has to choose. Test 3 passes, just. Nine relevant buyers at an assumed 50 per cent acceptance give each supplier about four or five possible meetings. But the 30 buyer diaries hold 210 slots. If they fill to about 85 per cent, that is roughly 180 meetings, or three per supplier. The buyers, not relevance, set the limit.

Test 4 settles it. Brokering 180 meetings by hand at ten minutes each is about 30 hours of work. With a meeting matrix, the same 180 meetings come from rules you set once.

An event with ninety people can still require the coordination of 180 meetings.

The example also shows how thin the margin is. If sales adds 20 more suppliers, the same buyer diaries give each supplier about 2.3 meetings, and the event drops below the line. Address that capacity limit before accepting additional supplier registrations.

What matchmaking really costs at a small event

The licence is the cost your managing director sees first. Three others decide whether the afternoon works.

• Licence: most providers price per event or per attendee, and minimum fees weigh more heavily on small events. Converve publishes guide prices per event size; the Match & Meet plan for 1 to 100 attendees starts at €4,950 net per event (converve.com pricing page, October 2026). The pricing models across the market, from per-attendee fees to annual licences, are compared in our event matchmaking software pricing guide.
• Organiser time: registration questions, a preference window before the event, schedule emails and a help point on the day. This work does not shrink in line with headcount. A 90-person event needs almost the same set-up as a 300-person one.
• Programme time: a meeting block takes time away from talks. At small events that is often a good trade, because the meetings are why most people came.
• Participant effort: every profile field is a small cost for the person filling it in. Ask only what your matching actually uses; our seven levers for better B2B matchmaking start with exactly that.

One argument you may hear is that small audiences are too small for matchmaking because an algorithm cannot learn from them. That is true for learned ranking models, which need data to improve. A rule-based meeting matrix has nothing to learn. It applies the rules you write, such as “buyers in packaging may meet suppliers in packaging”, and works with 30 participants just as it does with 3,000.

The right format for each size of event

If one of the tests fails, consider a format better suited to your participant mix and available time.

The last row is often the best answer for a small event. A short rotation at the start breaks the circles of familiar faces. The scheduled meetings afterwards make sure the suppliers who came for specific buyers actually sit down with them.

Converve runs matchmaking on a rule-based meeting matrix. As the organiser, you define which participant groups may meet one another. Participants get suggestions based on their interests, goals and categories, send 1:1 meeting requests, and every confirmed meeting gets a time slot. Because the rules are visible, you can explain to any participant why their diary looks the way it does. You can see how it works on our B2B matchmaking platform page, and the guide prices for each event size are on our pricing page.

Conclusion

Matchmaking at a small B2B event is not a question of headcount. It pays off when participants have more relevant counterparts than slots and enough of them to fill a diary. Below that window, a rotation, topic tables or your own introductions do the job for less.

The four tests take about ten minutes with your registration data. Is there a “who needs whom”? Can everyone meet everyone anyway? Does each participant have about six relevant counterparts for three meetings? And would brokering the meetings by hand cost you more than a licence?

So when your managing director asks whether a 90-person event needs matchmaking, you can answer with the number of meetings it will produce and what each one costs. If you want to check those numbers for your own event, get in touch with Converve.

Frequently Asked Questions

Is matchmaking worth it for an event with 50 attendees?

It can be, if there is a clear need for specific participant groups to meet and one side is larger than the number of meeting slots you offer. Fifty participants split into 15 buyers and 35 suppliers in a six-slot block need a way to prioritise meetings, so matchmaking helps. Fifty peers with no buyer and supplier roles are usually better served by topic tables or a short rotation.

What is the minimum number of participants for event matchmaking?

There is no established minimum headcount supported by research. A workable rule of thumb is that each participant should end up with at least three meetings, which needs about six relevant counterparts if roughly half of the possible meetings are accepted. Below that, introduce people by hand or run a rotation.

How much does matchmaking cost for a small event?

Licences are usually priced per event or per attendee, with minimum fees that weigh more on small events. Converve’s published guide price for its Match & Meet plan starts at €4,950 net per event for 1 to 100 attendees (converve.com, October 2026). Divide the licence by the meetings you expect to schedule to get a cost per meeting you can compare with staff time.

Can I run matchmaking for a small event without software?

Yes, while the total stays at a few dozen meetings. At an assumed ten minutes per hand-brokered meeting, 60 meetings take about ten hours of organiser time. At several hundred meetings, cancellations and rescheduling make a spreadsheet unmanageable, so include that time when weighing the cost of a meeting matrix.

Does matchmaking help if most participants already know each other?

Often more than at a large event. In a Columbia Business School study of a mixer with about 100 executives, about half of all encounters were with people guests already knew, even though 95 per cent wanted to meet new people (Ingram and Morris, 2007). Scheduled meetings and a short rotation break up those familiar circles.
