I’ve been the agency.
For the Tostitos Fiesta Zone at Super Bowl 2026, I was on the ground through Plan Experiential, the San Francisco agency I freelance with, and PepsiCo was right to buy it that way. A multi-day activation on Pier 39 needs a fabricator’s lead carpenter who can splice a damaged panel and a pier operations manager who will clear the back gate for a late truck, and a chip brand has no reason to keep either of those people on payroll for the other eleven months of the year. The agency keeps them in its phone. That’s most of what you’re paying for.
The guides that rank for this question mostly weigh control against cost and land on “hybrid,” which is fair. One of them even puts a number on it: in-house below about 150 guests, a full-service agency above about 250. Headcount is a decent stand-in for complexity! What I couldn’t find in any of them is the question I’d ask first, as someone who has handed back the radio at load-out more times than I can count: who will still be holding your badge scans in July?
The Table I’d Hand a VP of Marketing
| Option | Best for | How you pay | What they know on day one | What leaves at load-out |
|---|---|---|---|---|
| Full-service experiential agency | A one-off that has to be enormous, like a Super Bowl activation or a consumer launch on a public site | Project fee, plus production costs passed through | Fabricators, permit runners, venue contacts. Your product, barely. | Everything after the pier is handed back: the follow-up, the post-mortem, the people who learned your brand that week |
| Freelance producer | One show where you already have an internal owner and need a second experienced pair of hands | Day rate, booked for the build and show days | How a show floor runs. Nothing about your pipeline. | The radio, and whatever they noticed that never made it into the recap |
| In-house event marketer | A calendar that repeats: the same annual trade show, quarterly partner rooms, the dinner every conference week | Salary, all year, including the quiet months | Less than an agency about suppliers in a new city. More every month about your buyers. | Nothing. That’s the point of the seat. |
| In-house owner who hires the agency | Most B2B companies with one big show and a lot of small rooms | A salary, plus an agency fee in the months with a build | The owner knows the buyers. The agency knows the dock. | The build crew, which is fine, because the owner keeps the receipts |
Where Each Option Fits (and Where It Doesn’t)
A disclosure first. I’m looking for an in-house job, so I have a stake in the third row, and you should read the rest of this with that in mind.
The agency wins the one-off.If you have one giant consumer moment and no plan to do it again, nobody in-house will beat a good agency on build week, and I’d tell you that even while hoping you’d hire me. Where it struggles is recurring B2B work. An agency’s Year Two with you is often a new team’s Year One, relearning your product from the brief.
A freelance producer wins when the owner already exists.Somebody inside has to own the goal and the leads. Without that person, you’ve hired a very capable stranger who will (I say this with love, having been her) go home on load-out night and never find out what happened next.
In-house wins when the calendar repeats.It loses when it doesn’t. A company with one event a year and no second act is paying a salary for eleven quiet months, and the agency is the honest answer there. An in-house marketer also still needs outside builders. I would never fabricate a booth myself, and I’d be suspicious of anyone who offered to.
The mix is what I’d buildat most B2B companies I’d want to work for: one person inside who owns the year, hiring an agency or a freelance crew for the weeks that need more hands than the building has.
What the In-House Seat Actually Buys
Receipts. At Arxan I ran three straight years of RSA Conference, and I was still there ninety days after each one when the reps followed up (or didn’t). That’s the only reason we ever knew which parts of the booth were earning their keep. Pipeline contribution grew every year and Year Three was the highest of the three, built out of two years of our own numbers, which I wrote up in how I measure trade show ROI. No agency could have sold us that third year, because no agency was in the building for the first two.
The relationships compound the same way. At Illumio we ran partner roundtables in São Paulo every quarter, and every partner I onboarded in my first ninety days is still in Illumio’s book today. Seven years and 300+ tournaments at Presidio Golf taught me the small version of it: by year five the caterer picks up at 11 p.m., because you picked up for them once.
The Radio
Whoever you hire, ask who will be holding it at 7 a.m. on day one of the show, and whether that person will still have a company email address when the deals from that week close.
If You’re Deciding This Quarter
Count the rows on next year’s event calendarthat happened last year too. If it’s one, call an agency, and I mean that. If it’s most of them, you need an owner, and the first thing that person should do is write the January post-mortem nobody wrote this year.
I’d like to be that person on your team. Let’s talk! I’ll bring the agency phone numbers with me, and I’ll still be there in July.
