How to Fill a Room in a City Where You Know Nobody

Running an event somewhere you have no presence is a distribution problem wearing a marketing costume. You do not have an audience, so there is nobody to tell. Promotion assumes reach you do not have.

The thing that fills the room is other people's reach, arranged in a specific order, plus a decision about size that most organisers get exactly backwards.

Size the room to what you can fill

Decide the target number first, and set it low enough that you will hit it.

This is the single highest-leverage decision available and it is made carelessly more often than any other. Thirty people in a room built for thirty feels busy, sounds busy and photographs well. Thirty people in a room built for a hundred feels like a failure to everyone present, including you, at exactly the same attendance.

The second version also makes the next event harder, because the people who came will describe it to others as quiet. A first event in an unfamiliar city should be small on purpose, and visibly full.

Borrow the audience, in this order

1. The ten people who will definitely come.

Before any public promotion, get ten commitments. Anyone you know in the city, however loosely. Former colleagues, second-degree introductions, people who have replied to something you posted. Ask directly and individually, and ask each of them to bring one person who would find it useful.

Ten becomes twenty, and twenty is a room. It is unglamorous, it does not scale, and it is the only method that reliably works from zero.

2. Organisations that already gather your audience.

Every city has groups that already assemble the people you want: a co-working space, a trade association, a university department, a meetup that runs monthly, a local publication. They have the relationship you lack and they need content and reasons to contact their members.

Approach them with something specific and low-effort: you will run the session, they announce it to their list, their name appears alongside yours. The partner is not doing you a favour, they are getting an event they did not have to organise.

This is the highest-yield channel available to a first event, and it is underused because it requires asking rather than buying.

3. Speakers and guests chosen for reach as well as content.

Anyone on the programme brings their own audience if you ask them to. Give them something easy to share and a reason to share it, and be explicit at the invitation stage that promotion is part of the arrangement. Most people are happy to; almost nobody does it unprompted.

4. Paid promotion, last and small.

Local paid social can work for events because the targeting is genuinely geographic and the ask is concrete, and the platforms document the event and location formats available - Meta's business resources set out what the objectives actually optimise for. But it is the weakest of the four for a first event, because it reaches people with no reason to trust you. Treat it as a top-up once the room is already half full, not as the plan.

Make registration cost something

Free registration is why the room is half empty. Someone who has committed nothing has nothing to lose by not appearing, and a meaningful proportion of them will not appear.

The fix is not necessarily a ticket price. It is any small friction that filters for intent: a short application, a nominal fee, a question that takes a minute to answer. Each one reduces registrations and increases attendance, which is the trade you want.

The rest of that problem, and the reminder sequence that recovers most of the remaining gap, is covered in why people register and don't turn up.

Give people a reason that is not networking

"Networking event" describes a room, not a reason to leave the house. It also sets an expectation that the attendee must do the work.

What travels is a specific promise: a named person answering a specific question, a problem the audience recognises, a result they could copy. The title should be legible to someone who has never heard of you, because in this city, none of them have.

The practical test: could an attendee explain to a colleague why they are going, in one sentence, without mentioning you? If not, rewrite the invitation.

What to do on the day and after

Two things convert a first event into a second one.

First, capture consent properly. Ask on the registration form whether people want to hear about future events, and keep that separate from the registration itself. That list is the entire reason the second event is easier than the first, and how you handle the data is subject to the privacy rules of the market you are in - the UK regulator's direct marketing guidance is a reasonable reference for what consent has to look like.

Second, ask five attendees, in person, whether they would come again and who else should have been there. The second question is a recruitment channel and almost nobody asks it.

The realistic version

You will not fill a room in an unfamiliar city with promotion. You will fill it by finding ten people who will come, asking them to bring one each, partnering with someone who already has the audience, and choosing a venue small enough that the result looks like a success.

That is a less satisfying answer than a marketing plan, and it is the one that produces a full room. Once you have run it twice, you have a list, and the problem becomes an ordinary one.

General guidance. Data protection and marketing consent rules vary by jurisdiction; confirm the requirements where your attendees are based before collecting or using contact details.
