We're seeing it in the briefs coming through to us. Brands that experimented with in-housing are asking a more nuanced question: which capabilities belong inside and which belong outside?</p> <h2 class="gn-reveal"><span class="num">01</span>What Drove In-Housing and Why It's Reversing</h2> <p class="gn-reveal">The in-housing wave had a clear logic. Brands wanted more control, faster turnaround, and lower cost. They built teams, hired specialists, invested in technology, and reduced their dependence on external agencies.</p> <p class="gn-reveal">For some brands, it worked. For many others, it delivered some of what they hoped for and fell short on the rest.</p> <p class="gn-reveal">What brands consistently underestimated was the range of capability an agency brings. An in-house team can handle volume and speed. It struggles with strategic breadth, creative range, and the kind of external perspective that comes from working across multiple clients and categories simultaneously. It also struggles to scale for peak periods and to maintain momentum when key people leave.</p> <p class="gn-reveal">What we hear from brand-side marketing leaders who have been through this process is usually some version of the same thing: the in-house team is good at executing the plan, but less good at challenging it. And over time, that gap becomes commercially significant.</p> <p class="gn-reveal">The reversal isn't a failure of in-housing as a concept. It's a recalibration. Brands are now asking a more nuanced question: which capabilities belong inside and which belong outside?</p> <div class="gn-divider gn-reveal" aria-hidden="true"></div> <h2 class="gn-reveal"><span class="num">02</span>What These Brands Need That They Couldn't Get In-House</h2> <p class="gn-reveal">Understanding the specific gap is the key to positioning for this opportunity.</p> <p class="gn-reveal">Brands coming back to agencies after an in-house period are not looking for what they had before. They're looking for what the in-house team couldn't deliver. That's almost always one or more of the following.</p> <p class="gn-reveal"><strong>External perspective.</strong> An in-house team sees the same brand, the same market, and the same stakeholders every day. Over time, that produces tunnel vision. Brands that have experienced this are looking for an agency that can bring genuine outside thinking. Not just execute the brief, but challenge the assumptions behind it.</p> <p class="gn-reveal"><strong>Specialist depth they can't justify hiring for permanently.</strong> Senior strategists, creative directors, specialist channel expertise. These are expensive to hire and hard to retain when there isn't enough of the right work to keep them engaged. Agencies offer access to specialist capability without the permanent headcount cost.</p> <p class="gn-reveal"><strong>Creative range.</strong> In-house teams develop a house style quickly. It works for consistency but limits creative ambition. Brands that have noticed their work becoming predictable are looking for external creative input to push the work harder.</p> <aside class="gn-quote gn-reveal"><q>Agencies that try to sell against the in-house team lose. Agencies that show how they work alongside it win.</q></aside> <p class="gn-reveal"><strong>Scalability.</strong> In-house teams are sized for average demand, not peak demand. Agencies can flex. That flexibility has become more valuable as campaign volumes and marketing channels have increased.</p> <div class="gn-divider gn-reveal" aria-hidden="true"></div> <h2 class="gn-reveal"><span class="num">03</span>How to Position for This Conversation</h2> <p class="gn-reveal">The standard pitch doesn't work here. Brands that tried in-housing and are now looking for external support have a specific anxiety: they don't want to undo what they built or admit it failed. They want to find a way to use both.</p> <p class="gn-reveal">The agencies winning this business are not positioning themselves as a replacement for the in-house team. They're positioning as a complement to it.</p> <p class="gn-reveal">This means the conversation starts differently. Instead of leading with "here's what we do," the right opening is "tell us how your in-house team is set up and where you feel the gaps are." This signals that you understand the situation, that you're not going to dismiss what they've built, and that you're interested in solving a specific problem rather than selling a service.</p> <p class="gn-reveal">From that conversation, the pitch almost writes itself. You're not competing with the in-house team. You're completing it.</p> <p class="gn-reveal"><strong>Proof points that land in this context:</strong></p> <p class="gn-reveal">How you've worked alongside in-house teams before. Not just worked with brands, but specifically integrated with internal marketing functions. If you have examples of this, they're worth more here than any other case study.</p> <p class="gn-reveal">How you handle knowledge transfer and collaboration. Brands with in-house teams are protective of their internal capability. Agencies that show how they share knowledge and build internal capacity, rather than creating dependency, address a genuine concern.</p> <p class="gn-reveal">Your ability to flex. If you can articulate specifically how you scale up and down around an in-house team's needs, that's directly relevant to how these brands are now thinking about external partnerships.</p> <div class="gn-divider gn-reveal" aria-hidden="true"></div> <h2 class="gn-reveal"><span class="num">04</span>The Timing Question</h2> <p class="gn-reveal">This is a specific opportunity with a window. Brands that have gone through an in-house experiment and found it wanting are most open to agency conversations in the 12 to 18 months after that realisation. Before that, they're still invested in making it work. After that, they've either figured it out or made permanent structural decisions.</p> <p class="gn-reveal">The signals to watch for: senior marketing hires at brands that previously reduced their agency roster, budget announcements that suggest a return to campaign activity, or leadership changes at brands known to have in-housed aggressively.</p> <p class="gn-reveal">When those signals appear, being already in conversation (even a light-touch, thought leadership-led one) puts you in a very different position than starting cold.</p> <div class="gn-divider gn-reveal" aria-hidden="true"></div> <h2 class="gn-reveal"><span class="num">05</span>Practical Takeaways</h2> <aside class="gn-callout gn-reveal"> <div class="gn-callout__label">What this means for you</div> <h4>Five things to act on now.</h4> <ul> <li><strong>The in-housing reversal is happening, and the briefs are real.</strong> Brands that experimented with in-housing are coming back to market. This is a live opportunity, not a theoretical one.</li> <li><strong>These brands are not looking for what they had before.</strong> They're looking for what their in-house team couldn't deliver. Understand the gap before you pitch.</li> <li><strong>Don't position as a replacement. Position as a complement.</strong> Agencies that try to sell against the in-house team lose. Agencies that show how they work alongside it win.</li> <li><strong>Lead with a question, not a credentials deck.</strong> "Tell us how your in-house team is set up and where the gaps are" is a more powerful opening than any slide.</li> <li><strong>Proof of working alongside in-house teams is your most valuable case study in this context.</strong> If you have it, put it front and centre. If you don't, start building it.</li> </ul> </aside> </div></div>
