Events witha human pulse.
MAINSO stages the rooms where industries meet. We plan the floor, build the stands, fill the seats, and stand beside you on show day so your team can do the one thing that matters: shake hands and close.
Trusted by teams across healthcare, construction, food & drink and beyond.

What we do
One team, from the first sketch to the last truck.
Most shows are stitched together from five vendors who have never met. We keep it under one roof, so nothing falls through the gaps between them.
01 02 Trade shows & exhibitions
Floor plans that sell, traffic that flows, and exhibitors who rebook. We treat your show floor like a high street, not a car park.
- Floor planning
- Exhibitor sales
- Footfall design
03 Stand & space design
Stands and feature spaces built to be remembered, then built again next year. Drawn in-house, made by trusted hands.
- Concept & 3D
- Fabrication
- Install & dismantle
04 Show operations
The unglamorous engine: contractors, health and safety, build schedules, and a control room that answers on the first ring.
- Health & safety
- Contractor wrangling
- On-site control
Numbers are not the point of an event. They are just the easiest way to show we keep our word.

How we work
Four moves, one show
No mystery, no agency fog. You always know which move we are on.
- 01
Brief
We sit down, learn the industry you serve, and agree what a win looks like in plain numbers.
- 02
Blueprint
Floor plans, run of show, budget, and a build schedule you can hold us to.
- 03
Build
Stands go up, exhibitors get sold, delegates get registered. We chase every loose end.
- 04
Showtime
We run the room. You meet the people you came to meet. We debrief once the trucks roll out.
Recent shows
A few rooms we filled last season.
Industries change, the job stays the same: get the right people in the room and make the day run itself.
Who we are
We are an events team that grew up on the show floor.
MAINSO started with a handful of people who were tired of conventions that looked good in the brochure and fell apart at the door. So we built the kind of company we wished we could have hired.
We are planners, floor managers, stand builders, and sponsor-sellers under one roof. That means fewer hand-offs, fewer people pointing at each other when something slips, and one team that owns your show from the first sketch to the last truck.
We had run the same tired conference for six years. MAINSO tore up the floor plan, doubled our exhibitor revenue, and somehow made it feel calmer to run. They are the first call for next year.
