Selling 3,000 tickets to a concert nobody had run before

KOSTCON 2025 was a K-Drama OST concert in Dhaka for an audience no promoter had sold a concert to before. The campaign reached 2.5M+ people, drew 150K+ engagements and sold more than 3,000 tickets. This is the order we did it in, and why that order mattered.

A first-of-its-kind event has no proven demand

The fandom was real and large. What nobody knew was whether it would pay for a ticket, because it had never been asked. That is a different problem from a sold-out act returning to a city, and it cannot be solved by buying more reach: an audience that has never been asked to show up does not become convinced by an advert telling it to.

So the first job was not awareness. It was credibility with people who already knew the music and had no reason yet to trust the event.

Fifty creators before a single advert

We partnered with more than fifty K-Pop creators the audience already followed, so the first time most fans heard about KOSTCON it came from an account they had chosen to follow rather than from a brand paying to interrupt them.

The reason to spread it across fifty rather than concentrate it in five is that a fandom is not one room. It is many small ones with their own voices, and a concert needs enough of them nodding at the same time for the thing to feel real rather than promoted.

A lineup revealed, not announced

Every performing artist got a reveal moment of their own, carried by cinematic promotional films across platforms on a planned schedule rather than in one launch push.

An announcement is a single day. A sequence of reveals gives the audience a reason to come back, gives each artist's fans their own moment to react to, and gives the platforms more than one thing to distribute. The same information, spread so it can compound.

What it produced

2.5M+ total reach, 150K+ engagements, and more than 3,000 tickets sold. What is not published here is the budget, the fee or what we paid any creator, and those are the numbers that would tell you whether this is affordable for your event. Book a call and we will talk about them for your case.

Questions

How many influencers does a concert campaign need in Bangladesh?
KOSTCON worked with more than fifty, chosen on audience overlap rather than follower count. The number follows from how many pockets of a fandom you need nodding at once, not from a target set in advance. A smaller, tighter audience needs fewer.
Does this approach work for a local artist rather than an international one?
The two moves underneath it are not specific to K-Pop: reach an audience through accounts it already trusts, and spread the announcement into a sequence. We can only speak for what we have run, and KOSTCON is the clearest example of both.
How far ahead should ticket promotion start?
Early enough to run reveals in sequence rather than all at once, which is the whole advantage. Dhaka Dreams Concert shows that two weeks can be survived, but that was a rescue of an event already on sale rather than a plan anyone would choose.
