The most common selection error we see is not overpaying, and it is not booking a dud. It is booking someone excellent for the wrong room. It starts innocently enough: an organiser watches a speaker at an industry event, or reads the book, or sees a clip that lands, and the admiration quietly hardens into a decision. The speaker is chosen first; the event is then retrofitted around them. Everything downstream — the brief, the agenda, the awkward post-event conversation about why the room felt flat — follows from that inversion. Events are not interchangeable stages waiting for a voice. They are different jobs, and a speaker who is superb at one can fail another without doing a single thing wrong.

So before any shortlist, name the job. Here are the six rooms we are asked about most, what each of them actually needs, and how each of them most often goes wrong.

The AGM and the awards night

The AGM is the most unforgiving room on the calendar. Shareholders and directors did not come to be entertained; they came to be reassured that the people minding their money are serious. What the room needs is credibility and steadiness — a voice with weight, comfortable under scrutiny, able to talk about risk and the future without sugar-coating or theatre. What fails is the hype merchant. High-octane motivation delivered to an audience holding the annual report reads as evasion, and a room full of professional sceptics will quietly conclude that someone is compensating for something.

The awards night sits at the other end of the formality scale but obeys a similar law: the speaker serves the occasion. This room needs warmth and brevity. People are there to be celebrated, to eat, and to enjoy the company at their table; the speaker's job is to give the evening a lift and then get out of its way. The good ones know they are not the point of the night, and their twenty minutes feels generous rather than truncated. What fails is the smuggled keynote — forty minutes of frameworks delivered at 9.30pm to a room that has been sitting since seven. Nobody at an awards dinner has ever wished the speech were longer.

The sales kickoff and the all-staff conference

The sales kickoff needs energy, but energy is the entry requirement, not the job. The job is a message the team can carry into the field — something a rep can actually use in a hard quarter, compressed into a line or a story that survives the trip back to the territory. And there is a structural test most organisers forget: the speaker usually follows the numbers session. Whoever you book must walk on after targets have been raised, commissions restructured or a soft year dissected, and meet the room where that session left it. What fails is empty adrenaline — the speaker who lifts the room for an hour and leaves nothing behind. By Wednesday the sugar has burned off and the pipeline looks exactly as it did on Monday.

The all-staff conference is a breadth problem. The same forty minutes has to land for the warehouse and the boardroom, for the twenty-two-year-old in a first job and the veteran who has heard every transformation message twice. The room needs a story that works at every altitude — concrete enough for the people who make and move things, large enough for the people who plan them. What fails is a speaker calibrated for one stratum: the executive-suite strategist who loses the floor inside ten minutes, or the crowd-pleaser the leadership row finds thin. When we vet for these rooms, range is the first thing we look for — evidence the speaker has held mixed audiences, not merely senior ones.

The offsite and the industry conference

The leadership offsite is where arena craft goes to die. Twenty people around a U-shaped table do not want a performance; they want depth, interaction and a voice comfortable being questioned — interrupted, even — by people who interrogate arguments for a living. Small-room craft is its own discipline: reading the politics, working without the armour of staging and distance, letting the session become a conversation without losing its spine. What fails is the stadium speaker in a boardroom, projecting a performance at close range. Senior leaders spot a talk that cannot survive dialogue almost immediately, and once they have, the day is done.

The industry conference has the opposite problem: the audience has seen everyone. Delegates who attend three events a year have watched the circuit's reliable names deliver the circuit's reliable talks, sometimes more than once. This room needs fresh thinking — a genuinely new argument, an unfamiliar voice, or a familiar one pushed well past the talk everybody has already heard. What fails is the safe booking, precisely because it is safe: competent, polished, and identical to what the delegates sat through in March. The feedback will not say bad. It will say nothing new — and for a conference trading on insight, that is worse.

Six rooms, six different jobs — and one discipline underneath all of them. Start with the job of the event: what this particular gathering must achieve, for whom, and in what state they will arrive. Then, and only then, go looking for the voice that can do that job. Admire speakers as much as you like; keep a list if it helps. But the event is never built around the speaker. The speaker is chosen for the event — and the organisers who hold that order are the ones whose rooms everyone else tries to copy.
