Customer discovery interviews, and how many are enough
B2B customer discovery interviews: the sample size the research converges on, why your segments change that number, and the questions that get honest answers.
ReadA show with eleven meetings already booked and a show with a bowl of business cards cost the same. The difference is whether anyone did the outreach four weeks out, and this year the calendar moved.
There is a version of a trade show that costs you twenty thousand dirhams and produces a bowl of business cards. There is another version where you arrive with eleven meetings already in the calendar, two of them with people who would never have taken your call in March. The difference is not the stand. It is whether anyone did the outreach four weeks out.
This matters right now because the calendar moved. GITEX Global, the anchor event most MENA technology sellers plan their fourth quarter around, is running 7 to 11 December this year: a one day Summit on 7 December at Dubai World Trade Centre, then the four day Expo from 8 to 11 December at the Dubai Exhibition Centre in Expo City. The 2025 edition ran in mid October at Dubai World Trade Centre. If your outreach plan is a copy of last year's, it is currently about seven weeks early, and the window that actually works has not opened yet.
Eight weeks out, the person you want has not thought about the show. Their answer is a genuine "probably, remind me closer", which is not a meeting, and you have spent your one good email getting it. Reaching out again later means you are now the person following up on a non-commitment rather than the person with a reason to write.
One week out their calendar is full, half of it with internal briefings, and the slots that remain are the ones nobody wanted. Four weeks is where the show is real enough to plan around and the calendar is still soft. For a December event, that means the first half of November.
The exception is the senior end. A managing director who is flying in for two days and being handled by someone else needs six weeks, because their diary is built by an assistant working from a list that closes early. If the person you want is that senior, treat the four week rule as four weeks for everyone except the three names you most want, who get six.
The constraint that makes pre show outreach work is also the thing people skip: the list is not your pipeline. It is the intersection of your pipeline and the attendee list, and those are very different sets.
Three sources, in order of how well they pay:
What does not work is a list of companies you wish were going. The pre show message has exactly one advantage over a cold email in February, which is that it names a real place and a real week. Send it to someone who is not attending and you have thrown away the only thing that made it different.
The common failure is asking for a meeting at the show as though the show were the reason. It is not a reason. A buyer does not want a meeting because a venue exists.
The structure that works is short and has four parts: you are there on these days, you noticed a specific thing about them, here is the one question worth twenty minutes, and here are two concrete slots. The specific thing is what carries it, and it is the same discipline as any cold email, which we covered in how to write a cold email that gets replies.
Two details that change reply rates more than the wording. Name the slot rather than asking for availability, because "Tuesday 9 December, 11:00 or 15:00" is a yes or no question and "do you have time?" is homework. And say where, which this year means saying it carefully: the Summit on 7 December is at Dubai World Trade Centre and the Expo from 8 December is at Expo City, and those are two different parts of town. A meeting agreed without naming which one is a meeting that gets missed.
There are more people at a show than you have hours, so the real work is deciding who not to meet. Four categories, and only three of them deserve a slot:
| Who | Worth a booked slot? | Why |
|---|---|---|
| Open deal that has stalled | Yes, first priority | In person moves a stuck deal more reliably than any email. You already have the relationship, you need the momentum. |
| Named target you cannot reach | Yes | The show is the only context where a cold senior contact has a reason to say yes. This is the slot that justifies the trip. |
| Potential partner or reseller | Yes, if you have one ask ready | Both of you are already travelling, which removes the usual excuse. Go in with a specific proposal, not an introduction. |
| Anyone who walks up to the stand | No, do not pre book | Keep the gaps. Walk ups are the point of having a stand, and a wall to wall calendar means you staff the stand with nobody. |
That last row is the one teams get wrong. A calendar booked solid from nine to six looks like a successful outreach campaign and produces a show where every unplanned conversation is an interruption. Book roughly half the day and leave the rest.
A booked meeting at a show is worth nothing on its own. It is a first touch that happened to be face to face, and it sits in the same sequence as every other touch, which is why the arithmetic in how many touches it takes to book a B2B meeting does not stop applying because you shook someone's hand.
Write the follow up before you fly. Not the content, the mechanism: who sends it, how fast, and what it contains. The realistic target is same day for anything that went well, and the reason is competitive rather than aspirational. Your prospect is having thirty conversations that week. The note that arrives on Thursday evening lands while they can still remember which one you were. The note that arrives the following Tuesday arrives after they have returned to their actual job.
For a senior contact met at the Summit, the follow up is also the moment the gate appears, and the gate is usually procurement or an internal sponsor rather than the person you met. That pattern is the subject of how to get meetings with enterprise clients, and a show does not remove it. It just gets you past the first door faster.
Events are a channel that rewards preparation and punishes attendance. The strongest case for them is not lead volume at all, it is that they compress a relationship that would otherwise take two quarters into two days, and that argument is made well from the other side in Khaled Badr's piece on growing a business through events rather than advertising.
If you take one thing from the timing: open your diary now, find the first week of November, and block two hours to build the list. The outreach itself takes less time than people think. It is the list that takes the work, and the list is what decides whether you come home with eleven meetings or a bowl of cards.
We looked for defensible figures on pre show meeting booking and did not find any worth quoting. The numbers in circulation about trade show lead volume and cost per lead come from organisers and from vendors selling event software, both of whom are measuring the thing they sell. There is no independent research we would cite on how many pre booked meetings a four week window produces, so everything above is the mechanism and our own practice rather than a benchmark.
Worth noting too that GITEX's own 2026 page currently displays its attendance, exhibitor and country figures as placeholder zeros, so the exhibitor and visitor counts circulating in third party event listings for this edition are not coming from the organiser. We have cited the page for dates and venues, which it does state plainly, and left the crowd numbers alone. If you need a headcount to justify the trip internally, ask the organiser directly rather than quoting a listing site.
Finally, the four week rule is a rule of thumb from selling into Gulf events specifically, where a large share of attendees fly in and plan early. For a local show that people attend because it is down the road, the window is shorter and the outreach matters less, because they were coming anyway.
Send us the event, the stand or pass you have booked, and five accounts you want in the room. We will tell you which of the five are realistic for a four week window, which need six, and what the opening message should say.
