At IPW 2024, a buyer appointment lasted 15 minutes. At IMEX Frankfurt 2026, a one-to-one meeting lasts 30 minutes. Slush 2026 gives founders and investors 25 minutes, followed by a five-minute break. The right duration depends on what participants need to discuss.
As the organiser, you choose the meeting length, format and booking process to suit your audience. This guide explains what counts as a B2B meeting at an event, which four formats organisers use, how long each should last and which scheduling model fits your programme.
Start with the intended outcome of a conversation, then work out how much time it needs and how participants will find and book it.
What is a B2B meeting at an event?
A B2B meeting at an event is a pre-arranged business conversation between two or more participants with a fixed time, a fixed place and a known purpose. Typical pairs are buyer and supplier, investor and founder, or a research institute and a company looking for a partner. The organiser provides the setting and booking process; participants agree what they want to discuss.
Three features separate it from other conversations on the show floor. It is booked in advance or on the spot through a system, not by chance. Both sides know who they are meeting and why. And the organiser can count it, which turns networking into something you can report.
Spontaneous conversations at stands or over coffee are also part of event networking. For reporting, distinguish these from booked appointments. Where the line runs, and why it matters for your reporting, is explained in our article on event networking versus matchmaking. Sessions on stage are a different category again: plenaries, panels and workshops serve an audience, not a pair. Our overview of conference session types covers those.
For exhibitors assessing whether to return, useful meetings can be more informative than visitor numbers alone. Record both the appointments held and any agreed next steps.
Four formats and what each one is for
Choose the format according to the discussion you want to make possible. Organisers mostly work with four formats, and each one serves a different purpose.
The one-to-one meeting
Two parties, one table, one topic. This is the core format at trade shows, investor conferences and partnering events. At IMEX Frankfurt 2026 the organiser describes it as “a 30-minute meeting with an exhibitor booked by you, the buyer”, and the event reported 63,000 booked meetings (IMEX, 2026). Use it when a specific deal, partnership or investment is on the table.
The roundtable
One host, a small group, one guiding question. A roundtable typically brings together “a dozen or so attendees” for about an hour (A Media Operator, August 2026). It suits topics where peers learn from each other, or where a supplier wants to test a product idea with several buyers at once. IMEX runs a related variant called group appointments, in which groups of buyers attend an exhibitor presentation. If you plan one, our guide to running a roundtable discussion covers table size and moderation.
The hosted buyer appointment
This is a one-to-one meeting with a condition attached. The organiser pays for part or all of the buyer’s trip, and in return the buyer commits to a minimum number of meetings. At IPW 2024, buyers had to request and accept at least 25 appointments, or their registration was invalid (U.S. Travel Association, 2024). IMEX asks its hosted buyers for “at least six to eight a day” (IMEX, 2026). That commitment helps organisers plan a meeting programme for exhibitors, although each appointment still needs a relevant match and both parties to attend. How many meetings to require is covered in how many meetings each hosted buyer should get.
The speed format
Short, fixed rounds with many partners in a row. Meet the Buyer 2026 in Northern Ireland uses “10 minute scheduled appointments” and plans more than 350 meetings between more than 25 buyers and more than 150 suppliers (Northern Ireland Chamber, 2026). Brewbound Live 2025 also ran “10-minute, pre-scheduled, private conversations” between brands and retail or distribution buyers. Use short appointments to establish whether there is a fit and whether a longer follow-up is worthwhile. Our article on speed networking at B2B events explains the rotation maths.
| Format | Group size | Typical length | Best for |
|---|---|---|---|
| One-to-one meeting | 2 parties | 15 to 30 minutes | A concrete deal, partnership or investment |
| Roundtable | up to about 12 | about 60 minutes | Peer exchange, testing an idea with several buyers |
| Hosted buyer appointment | 2 parties | 15 to 30 minutes | Guaranteed meetings for exhibitors, funded buyers |
| Speed format | 2 parties, many rounds | about 10 minutes | Fast qualification of many potential partners |
The typical lengths are drawn from the examples in this article (IMEX 2026, IPW 2024, Meet the Buyer 2026, A Media Operator 2026).
How long should a B2B meeting be?
Length follows the purpose, but it also sets your capacity. Here is what the events above actually use.
| Event | Meeting length | Source |
|---|---|---|
| Meet the Buyer, Northern Ireland | 10 minutes | Northern Ireland Chamber, 2026 |
| IPW (U.S. Travel) | 15 minutes | IPW 2024 appointments page |
| GREENET brokerage event (online) | max. 20 minutes | GREENET, January 2026 |
| Slush, Helsinki | 25 minutes plus 5 minutes break | Slush meetings info, 2026 |
| IMEX Frankfurt | 30 minutes | IMEX, 2026 |
A useful rule of thumb follows from these examples. Ten minutes is enough to find out whether there is a fit. Fifteen to twenty minutes allows a structured first conversation with a short presentation. Twenty-five to thirty minutes leaves room for a demo, real questions and an agreed next step.
Longer appointments reduce the number that fit into a fixed meeting window. The chart shows how many meetings one seat can hold in a six-hour meeting window, with five minutes for changing tables after each slot.
Capacity
Meetings per seat in a six-hour meeting window
Own calculation: 360 minutes divided by slot length plus 5 minutes changeover, rounded down.
Moving from 15 to 30 minutes almost halves what one table can deliver. For an exhibitor, that can be the difference between 18 and 10 conversations a day. Before fixing the slot length, decide whether exhibitors need many initial conversations or more time to explore a smaller number of opportunities.
The changeover matters too. Slush builds a five-minute break into every slot. IPW considers stand locations when it schedules, so that buyers do not cross the whole hall between back-to-back appointments (IPW, 2024). Without a buffer, the first late meeting delays every meeting after it.
Three ways to schedule B2B meetings
Slot length decides how many meetings fit. The scheduling model decides who gets them. In practice, organisers use three models, and many combine them.
- Request and accept: participants send meeting requests, the other side accepts or declines, and the accepted meeting takes a slot. At Slush 2026, participants can have up to 50 open requests at once, and a slot only counts as busy once a meeting is accepted. This model rewards initiative. It does not guarantee anyone a full diary.
- Preference-based schedule: participants rank or select whom they want to meet, and the organiser or a system builds the diaries. IPW 2024 uses an “appointment scheduling algorithm” that places mutual requests first. At IBTM World, the team matches buyer and exhibitor preferences into a personal diary, and buyers can use “any remaining slots to schedule your own meetings”. This model fills diaries, which is why hosted buyer programmes favour it.
- Curated approval: participants request meetings, and the organiser reviews each one before it goes into the diary. Brewbound Live 2025 states that “requests are reviewed and approved to ensure the best matches”. This gives you the most control, at the cost of staff time.
All three models need clear rules on who may request meetings with whom. A buyer programme may prioritise buyer–supplier appointments; a partnering event may also need supplier–supplier or research partnerships. Set those rules before scheduling opens, and decide how any later changes will affect appointments already confirmed. Our guide to business matchmaking at events treats it as one of 18 success factors.
Converve lets you define these rules in a meeting matrix, per participant category: who can request whom, who can only view whom, and who stays hidden. Participants then either send meeting requests and pick time slots, or rank whom they want to meet so that the Meeting Generator can build complete schedules for you to review and publish. In both cases, confirmed meetings are scheduled without clashes, including table and room assignment. See how this works on the B2B matchmaking platform page.
From registration to follow-up
The scheduling model only works if the steps around it are in place. Most programmes follow the same sequence, regardless of format.
Process
How a B2B meeting programme runs
- Registration Collect profiles Offer, need and category for every participant; meetings can only be as good as these fields.
- Before scheduling Set rules and slots Who may meet whom, slot length, buffer, meeting area and number of tables.
- Booking window Open requests or rankings Request and accept, ranked preferences, or requests with organiser approval.
- Before the event Publish schedules Each confirmed meeting with time and table number in the participant's agenda.
- On site and after Track and follow up Kept meetings, no-shows, ad-hoc meetings and the follow-up rate.
Two operational details need particular attention on the day. First, the place: every meeting needs a findable table. Slush assigns a table number to each confirmed meeting and keeps ten tables free for ad-hoc meetings (Slush, 2026). Second, attendance: distinguish booked appointments from meetings that actually take place. How to measure no-shows honestly is explained in our article on event meeting no-show rates.
After the event, ask participants which meetings led to a follow-up and what they agreed to do next.
Frequently Asked Questions
What is a B2B meeting at an event?
A B2B meeting at an event is a pre-arranged business conversation between two or more participants, such as a buyer and a supplier, with a fixed time, place and purpose. It is booked through the organiser’s meeting system and can be counted, which separates it from casual networking at a stand or in the coffee break.
How long should a B2B meeting at an event last?
Most events use between 10 and 30 minutes. Speed formats use about 10 minutes (Meet the Buyer Northern Ireland, 2026), IPW 2024 used 15 minutes, Slush 2026 uses 25 minutes plus a five-minute break, and IMEX Frankfurt 2026 uses 30 minutes. Shorter slots suit qualification, longer slots suit demos and deal conversations.
How many B2B meetings can a participant hold in one day?
It depends on the slot length and the meeting window. In a six-hour window with five minutes of changeover, one seat can hold 24 meetings at 10 minutes, 18 at 15 minutes and 10 at 30 minutes (own calculation). Hosted buyer programmes usually ask for less: IMEX recommends at least six to eight meetings a day for its hosted buyers (2026).
What are the main B2B meeting formats?
The four main formats are the one-to-one meeting, the roundtable with one host and a small group, the hosted buyer appointment with a minimum number of meetings, and the speed format with short, fixed rounds. They differ in group size, length and purpose, from fast qualification to a concrete deal.
How are B2B meetings scheduled at events?
Organisers use three models: request and accept, where participants book each other directly; preference-based schedules, where participants rank whom they want to meet and a system or team builds the diaries (as at IPW and IBTM World); and curated approval, where the organiser reviews each request. Many events combine them.
Choose the purpose before you choose the slot
A B2B meeting programme is a set of linked decisions. The purpose of the meeting decides the format. The format decides the length. The length decides how many meetings each table can hold, and the scheduling model decides who gets them.
Write down the meeting purpose, booking rules and capacity assumptions before opening requests. Afterwards, report appointments held and follow-up activity alongside the number booked.
