The market is moving faster than any single agency partner can keep up with. Not because AORs got worse, but because AI is producing new tools and channels faster than one shop can absorb. For most of the last decade, brands treated AOR vs. indie as an either/or. That model isn't dead. It's just no longer enough alone.
Only 11% of multinational marketers think their current agency model is fit for purpose, and 88% say they want more flexibility than it currently provides, according to a WFA and MediaSense survey. The fix isn't abandoning the AOR. It's pairing it with an indie: the AOR anchoring scale, integration and governance, while the indie supplies speed, specialization and frontier intimacy as platforms reshape the channel.
Sophisticated brands have already answered the question, "Should we use an indie?" In fact, most do, albeit in informal pockets. Once both agencies are hired and onboarded, the 3 parties need to decide who owns what, where friction might arise and how to prevent the AOR and the indie from accidentally working against each other rather than for the brand.
Why the team model is better
An AOR earns its role through scale. It manages the bulk of media investment, holds the cross-channel plan together and protects brand consistency across markets and teams. That breadth is exactly what makes it hard for an AOR to also be the fastest mover on every emerging capability. AI-driven marketing is producing new tools and channels faster than any single agency can build.
Specialist shops solve the speed problem. An indie agency can go deep on one capability, whether that's answer engine optimization, retail media or first-party data strategy, and move faster than a partner managing dozens of workstreams. But that same focus is a liability at scale. An indie without governance or a clear boundary around its remit tends to either overreach into territory the AOR already owns or operate in a silo that never connects back to the broader plan.
Brands can structure the relationship to ensure each partner has a distinct job to clear up any confusion. The brand sits at the top of the triangle. It owns outcomes, sets the remit for each agency and makes the call when the AOR and the indie disagree. The AOR covers media investment, cross-channel planning and everything where consistency matters more than speed.
The indie supplies speed and specialization on whatever capability is moving fastest right now. It works within a tight, written scope, is rigorously tested and delivers candid feedback like a bigger, more exposed partner often can't afford to.
Making it work in practice
The relationships that hold up share a few habits. They write the indie's remit down before any contract is signed, confirming it doesn't duplicate something the AOR already owns. They run a joint kickoff with both agencies in the room rather than 2 separate briefings, and they agree on a single measurement framework before either partner begins work.
They also protect the boundaries once work is underway. That means documenting which agency owns which lane, agreeing in advance on what happens when an indie's pilot is ready to scale into the AOR's core plan and making sure neither agency's incentives reward undermining the other. Every quarter, the brand, the AOR and the indie should meet to assess whether the arrangement still fits or whether the indie's remit needs to graduate, expand or retire.
The real question isn't AOR or indie
Most 3-way agency relationships don't fail with a dramatic breakup. They fail slowly over time: the AOR stops sharing data, the indie starts creeping into territory that isn't its own and the brand ends up refereeing a turf dispute instead of running a marketing program.
The brands getting this right have stopped asking whether to work with an AOR or an indie. They're asking how to structure the relationship between the 2 so that the tension between scale and speed works for the brand rather than against it.
