What the Campaign In-Housing Summit 2025 revealed about 2026

London played host to one of the more energising events in the marketing calendar this year. Campaign’s In-Housing Summit brought together a small but sharply focused group of in-house leaders, creative directors, and marketing operations heads to debate where the discipline is heading. The room was compact. The conversations were not.

Here’s what stood out, and what it means for in-house teams planning their next move.

The in-housing moment is real, and accelerating

There was no ambiguity in the room on this point. In-house teams are gaining ground. Traditional agencies are losing it. The shift is not a trend; it’s a structural change driven by cost pressure, speed expectations, and a growing conviction that brand knowledge belongs inside the building.

Fast, cost-effective, hybrid models are taking over. The old binary of “build an in-house team” versus “hire an agency” is collapsing. What’s replacing it is more nuanced, and more interesting.

The studios and internal agencies that are winning are not the ones that did one or the other. They’re the ones that built a core in-house capability and then made deliberate choices about what to produce internally versus what to produce through external partners.

Tier systems are redefining how studios work

One of the sharpest strategic frameworks discussed was the T1, T2, T3 tier system. Not every piece of content deserves the same level of budget, time, or creative attention. Studios that treat all work as equal end up producing neither the hero content that builds brand equity nor the volume content that keeps the business moving.

The tier model fixes this:

T1 work is your flagship content. Brand films, hero campaigns, high-stakes launches. These require the full studio capability: senior creative direction, premium production, rigorous review.
T2 work is programmatic but meaningful. Regional campaigns, product explainers, thought leadership video. These follow templated workflows that protect brand consistency without requiring T1 resources for every shoot.
T3 work is high volume, lower complexity. Social cuts, internal comms, evergreen content. These should move as fast as possible, often through self-order systems or templated content products that bypass the studio team entirely.

The studios that thrive in 2026 will have a clear answer to where each brief sits, and a different production pathway for each tier. Without that clarity, the studio becomes a bottleneck for T3 work while struggling to give T1 work the attention it deserves.

AI is a productivity tool, not a creativity replacement

AI was a consistent thread throughout the day. What was notable was the precision of the conversation. Nobody was debating whether AI belongs in the in-house workflow. The question was where it belongs.

The consensus: AI earns its place on the tasks that consume time without requiring creative judgment. Tone of voice checks. First-draft transcription. Format adaptation. Task automation across repeatable workflows. These are exactly the kinds of operations where AI Assisted services deliver real speed gains without touching the creative core.

What was explicitly off the table was any suggestion that AI should lead creative direction. The message from across every panel was consistent. Human creativity is the point of an in-house team. The brief, the concept, the creative vision, the relationship with the brand: these stay with people. AI accelerates the production of that vision. It doesn’t replace the vision itself.

For in-house studios that have been anxious about where AI fits, this framing is useful. It’s not a takeover story. It’s an efficiency story. And done well, it frees senior creative capacity for the work that actually matters.

Hybrid is the new operating model

Every panel discussion touched on the same structural reality: in-house teams will need external resource partners to meet demand, scale operations, and service their stakeholders. Nobody was sheepish about it. The conversation had moved past whether to partner externally and on to how to do it well.

The demand for video content is not slowing. Business units want more. Regional teams want local content. The organisation expects faster turnaround. Internal headcount cannot grow linearly with that demand. It never could.

The studios that are scaling successfully are building hybrid operating models. They retain a core internal team for creative direction, brand governance, and high-priority work. They plug into external production networks for everything that requires geographic reach, volume capacity, or specialist skills the internal team doesn’t carry.

The internal team architects the system. External partners run production across markets. The studio stays in control of standards, approvals, and the final work. From the outside it still looks like one studio. From the inside it runs like a much bigger one.

What this means if you run an internal studio

If there was one tension that kept resurfacing. In-house teams are being asked to do more with the same headcount, and the ones that are managing it aren’t doing so by working harder. They’re doing it by being deliberate about what the studio should and shouldn’t own.

That means getting serious about tier systems so T3 volume doesn’t eat the capacity that T1 work needs. It means using AI on the parts of the workflow that consume time without needing creative judgment. And it means being honest that external production partners aren’t a compromise — they’re how you actually scale without losing the creative quality that justified building an internal team in the first place.

The studios that will be worth talking about at next year’s summit are the ones that figured out how to grow the output without diluting what makes their work good.

If you’re working through how to extend your internal studio’s production capacity, find out how 90 Seconds works alongside in-house teams to handle production across 100+ countries, without replacing the studio at the centre of the operation.

The in-housing movement has momentum. The studios that make it count will be the ones that build for quality and capacity at the same time.
