Organising company events — a guide for the executive assistant in a startup

Your CEO wants an event before the end of the quarter. You have a date, a rough headcount, and two lines in Slack. Everything else is inference and the risk is yours.

The season decides half the plan before you touch it. An August all-hands belongs outside until the rain comes. A December investor evening needs a room that photographs warm. January is cheap and available because nobody wants it. June is neither.

The brief you actually received

Two sentences. A headcount that might double. A vague date tied to a product milestone that will slip. Your job is to turn that into a run-sheet the CEO can glance at the morning of and a room that makes them look good in front of the board.

You are not planning your own event. You are planning on behalf of someone whose taste you infer and whose approval comes in pieces. That changes what you need from a supplier: decisions in writing, a single point of contact who will still answer at eight the night before, and a plan B that does not require you to ask the CEO anything while guests are arriving.

What the season does to the plan

Summer: everyone wants outside until the weather turns. You need a venue with a real indoor backup, not a marquee in a courtyard. The switch happens four hours before doors, and it is not your decision — it is the forecast and the caterer's tolerance for rain on hot plates.

Winter: the room photographs dark by four in the afternoon. You need a venue that works under artificial light or you accept that half the event is invisible to the social media you were asked to generate. Outdoor spaces do not winterise as well as their marketing suggests.

Shoulder season: April and October are when availability opens and cost drops, but the temperature swings fifteen degrees between noon and eight. Your guests will arrive dressed wrong.

The venue comes first

Not the theme, not the entertainment, not the message. The room is the only part of the evening you cannot change on the day.

You need capacity for the top of the headcount range, not the number you were given. Startups invite more people than they plan for and do it the week before. A venue at capacity feels tense in photographs.

You need to know what the handover looks like. Some venues give you the keys at nine and leave. Others require their own staff on the floor and charge by the hour. If the CEO is still in the room at midnight with the last three people who matter, you need to know whether that costs you anything.

Ask what fails in that room. The power, the acoustics, the caterer access, the single toilet for sixty people. The venue will not volunteer it.

The part that goes wrong is always sound

The microphone that cuts out during the speech. The laptop that will not connect. The screen the CEO sees for the first time when guests do.

Run the full presentation the afternoon of, in the room, with the person speaking. Not a tech check — a full run. The CEO will not want to. Insist anyway. The failure happens in front of the board, but the accountability is yours.

If the event is being photographed for the next funding deck, the lighting rig is not optional. A phone camera in a badly lit room makes a series A look like a staff birthday.

Two kinds of event supplier

One kind plans the event, then sends the brief to a lighting subcontractor they have never worked with, a separate AV company, a caterer from a list. They coordinate by email and earn a margin on every line. When something breaks, you are calling someone who is calling someone else.

The other kind quotes, builds, and runs the night with their own crew. The person who answered your first call is the person in the room at seven hanging the rig. After 5 Events is the second kind.

That structure shows up in two places: how fast you get a decision when the brief changes, and whether the crew on the floor has run this exact combination of room and rig before.

What actually happens on the night

The crew arrives hours before your caterer. They find the power, map the room, hang the lights, test the screen. By the time you walk the space, it is done or it is not.

You need a run-sheet with call times, not just an order of events. When does the CEO arrive? When do the first guests see the room? When does the speech happen and how long does the changeover to dinner take?

You need one phone number that answers during the event. Not the main office line — the person on site.

The budget will change

Startup budgets are attached to funding rounds and quarterly burn rates. The number you were given in March is not the number you have in May.

Lock the venue and the crew first. Everything else — the bar, the entertainment, the swag — can scale. The room cannot.

Get the quote in writing with a breakdown. When the budget gets cut, you need to know which line to drop without starting over.

What to settle before you call anyone

The date range, even if it is loose. The likely headcount and the actual maximum. What the CEO is measured on — a relaxed evening where the team talks to each other, or a polished showcase for the investors in the room.

Whether this event ends at ten or at two, because the venue cost and the crew cost are different by half.

What happens if it has to move. Startups reschedule. You need a supplier who holds the date and reconfirms.

The decision now is whether you are managing this yourself or handing it to people who have done it enough times that the risk is theirs.

Who is writing this

A crew, not a middleman

These guides are written by After 5 Events — the team that grew out of the After 5 band and DJ roster and has stood on the stage itself. We are not an agency that forwards your brief to subcontractors and takes a commission on every line: the people who plan your evening build the stage, run the sound and light, and are in the room when the doors open.
