Reimagining the In-House Agency

For years, in-house agencies (IHAs) have been the holy grail of marketing efficiency. They were faster, cheaper, and closer to the brand than relying on external agencies and partners. But today, as budgets tighten and speed-to-market is measured in days, not months, strategy can feel outdated even before launch. And many companies are rethinking the equation: What belongs in-house? What should be outsourced, or automated? And where does AI fit in? 

Market forces from cost-cutting pressures to evolving talent needs are influencing in-house agency structures. At the same time, external factors such as a changing political climate and rapid technological advances mean campaigns must evolve in real time. Generative AI has also transformed how strategy and storytelling come together. And the rise of “vibe marketing,” where campaigns are built around mood, movement, and cultural resonance rather than hard data or demographics, reflects a new creative instinct powered by AI tools. 

Even high-profile internal shops aren’t immune to the shift. Liquid Sunshine, the award-winning in-house agency behind Keurig Dr Pepper, was recently dismantled as they chose to move away from their in-house creative model. And while Mark Zuckerberg predicted that AI will eventually take over agency work, the reality today is far from apocalyptic. Instead, it is ushering in an era of nimble decision-making that blends human creativity with AI-driven insight.

From Consolidated to Connected: How AI Is Rewriting the IHA Playbook 

For many IHAs, capabilities can lag behind ambition: A 2025 Gartner survey found more than a quarter of CMOs have limited or no AI adoption in their marketing campaigns. That gap is forcing teams to make critical choices about how to build, buy, or borrow the technology they need to stay competitive.

Some brands are building proprietary AI systems: A massive technical and financial lift that demands new governance frameworks and training programs. For example, Adobe leverages the tools created for external partners for in-house work. Second Wave, the IHA for Aimbridge Hospitality, created closed-source, proprietary AI platforms that allow new hotels and projects to autonomously jumpstart brand-building

Other IHAs are partnering with external agencies that have their own AI infrastructure, a choice that can unlock efficiency but sometimes means ceding a bit of control. U.S. Bank, for example, has developed a hybrid approach, using agency Supergood for heavier lifts, while using their own in-house systems for everyday marketing efforts.  

Either way, workflows are being rewritten. The once-clear boundaries between internal and external teams are blurring, requiring tighter communication, shared platforms, and co-created content pipelines. Unilever’s Beauty AI Studio is a perfect example. “We used to send briefs off and get content back. Now it’s this agile, iterative approach,” Selina Sykes, Global VP and Head of Marketing Transformation for Beauty and Wellbeing, told Digiday about how the beauty brand is shifting.  

Turning Pressure into Possibility 

In-house agencies are at an inflection point. The pressure to do more with less can feel relentless. But it’s also sparking innovation. Constraints are forcing teams to rethink legacy structures, pilot new workflows, and uncover efficiencies that create both creative and budgetary flex. 

The first move is clarity. Map how work actually gets done … not how it’s supposed to get done. Identify bottlenecks, overlapping roles, and where technology is underused or skills are lagging. A fresh set of eyes can help: many brands are bringing in consultancies or external auditors to benchmark performance and uncover hidden inefficiencies. 

From there, experiment in controlled environments. Pilot hybrid workflows that combine AI-assisted production with human oversight. Start with lower-stakes campaigns to test new processes, clarify ownership, and measure output. The goal isn’t to do everything internally, but to decide what belongs in-house, what can be automated, and what’s best handled by trusted partners.

Upskilling is critical. As creative, marketing, and tech roles continue to converge, AI fluency and cross-functional collaboration are becoming baseline expectations. Teams that invest in training now will be better positioned to lead, not follow, as tools and platforms evolve. Just as important is finding the right partners who complement internal strengths, bring specialized expertise, and can flex as priorities shift. 

If projects stall in approvals, campaigns feel repetitive, or AI tools sit idle, those are signs it’s time for your IHA to recalibrate, not rebuild. The strongest IHAs see transformation as a continuous cycle of testing, learning, and scaling what works. Because at this turning point, the real advantage isn’t size or spendIt’s the ability to stay flexible, adapt fast, and turn every constraint into a catalyst for better work. 

The Future of IHAs is Human 

The next era of in-house work isn’t defined by automation. It’s defined by alignmentbetween people and platforms, insight and execution, creativity and technology. Because while AI may be able to execute campaigns, it’s people who decide which campaigns matter. Teams are the connective tissue that allow brands to pivot, sense cultural shifts, and build authentic identity in ways only humans can. 

Creative Circle helps brands build flexible, future-ready teams that blend human expertise with emerging technology. Whether you’re reimagining your IHA or exploring AI-enhanced workflows, we can help you find the right mix of people, partners, and potential.

One of the hottest questions in marketing these days is: are you in, or are you out? Many brands are setting up in-house teams to do work traditionally done by external agencies, giving birth to a new advertising and marketing model that may just have staying power.

The Association of National Advertisers, or ANA, has been doing a study every five years called The Continued Rise of the In-House Agency. The 2023 edition shows that 82% of marketers now have in-house agency teams — up from 78% in 2018, 58% in 2013, and just 42% in 2008.

What is an “in-house agency”?

For the ANA study, “in-house agency” was defined as “a department, group, or person that has responsibilities that typically are performed by an external advertising or other MarCom agency.”

In-house agencies, sometimes called IHAs, center on an internal marketing team that handles advertising exclusively for the company. IHA employees leverage their in-depth knowledge of the brand and its needs to create marketing strategies and craft campaigns without the help of an external party.

The ANA report “definitively shows that in-house agencies have become a firmly entrenched part of the holistic marketing ecosystem and are now a mainstay among a majority of marketers,” said ANA CEO Bob Liodice. But he hedged, “Agencies still play an important role for marketers, witnessed by the fact that 92% of respondents still use them. But the growth of in-house capabilities has clearly changed the client/agency relationship over the past 15 years.”

In-house versus External

Moving advertising and creative in-house is one of the most popular trends in marketing — but there is no one-size-fits-all solution. Some companies may find the initial time and investment to set up an in-house team outweigh the possible benefits. Two distinct IHA models have emerged: in-house and hybrid in-house agencies.

The completely in-house agency builds out all the digital marketing functions within the company, which gives the business total control of its data, the ability to shift tactics quickly, and confidence that privacy regulations are being followed with data. Contrast that with agency marketing — the traditional model — where marketing and advertising work is outsourced to an external team that manages all a company’s marketing and advertising work. Agencies theoretically have the strategy, connections, resources, and know-how to successfully promote a business. They often have teams dedicated to specific tasks like strategy, media buying, copywriting, design, project management, and account management who interface with the client.

Somewhere in between, we have a hybrid in-house agency model, where critical data is owned and lives with the brand. The brand usually also owns the media accounts, adtech accounts, and data management and has a small team dedicated to managing external agency activity with clearly defined goals. Marketing campaign infrastructure and accounts live with the in-house company team, while an external agency runs campaigns and handles digital data. This model often works well for companies with small digital marketing teams that need more resources and know-how to manage data in-house. Brands will often outsource media buying, especially programmatic buying, which helps explain the growing popularity of the hybrid model.

In-house marketing and external advertising agencies each have positive and negative aspects; the utility of each option varies depending on your business. Here are some pros and cons of each.

First, the pros of in-house agencies:

  • Cost — Companies often find that having an in-house agency costs less to fund and maintain, particularly for small companies. A different ANA study showed that cost efficiency is the top benefit that brands with in-house teams cite, followed by brand knowledge and nimbleness.
  • Communication improvements – An IHA bolsters communication internally between the marketing team and other departments, allowing for better cross-functional sharing of information and resources and boosting collaboration. This can help the marketing team complete projects faster, sparking new ideas and opportunities.
  • Brand knowledge — An IHA is steeped in knowledge of the brand they work for and is familiar with all aspects of the industry, enabling them to fully assess the company’s needs and craft marketing strategies that best fit at any given moment.
  • Control — Having transparency into costs and operations, especially in media buying operations, makes it much easier to identify and implement optimization tactics.
  • Data/tech ownership — As first-party data ownership becomes increasingly critical in a cookie-less, privacy-first world, there are advantages to having marketing technology and adtech in-house.

And now, some cons of IHAs.

  • Talent acquisition timeline — Building an in-house marketing team takes time. It may require an extended period to recruit, identify, interview, hire, and onboard new candidates.
  • Recruitment costs — Whether companies pay outside recruitment agencies or hire an in-house recruiter, there is a cost associated with talent acquisition.
  • Stagnant creative — An in-house team may come to rely on just a few creative styles and strategies, which can impact the ongoing success of your company’s marketing.

Here are the pros of working with an external agency:

  • Advertising fluency — Ad agencies have typically worked with hundreds and sometimes thousands of clients, which means they’ve pretty much seen it all. An ad agency may suggest activations or concepts that a brand has not considered, opening the door for innovative engagement and messaging.
  • Resources — Ad agencies have access to resources like software, high-end printers, digital equipment, and other tools that in-house marketing teams often can’t afford.
  • Connections — You know the adage, “it’s not what you know, it’s who you know” — and that holds especially true for ad agencies, which typically have connections to production companies, advertising platforms, and high-level execs that can elevate exposure for a company.
  • A plethora of creativity — With many employees and specializations, ad agencies have a leg up on offering cutting-edge marketing strategies and activations.

And now, some cons about working with traditional ad agencies.

  • Less in-depth knowledge of your brand — Agencies have many clients, so they must learn many different brand stories. Businesses must teach their agency about their products, audience, culture, goals, and future vision. This takes time, and time cost money.
  • Many clients (sometimes too many) — With numerous clients and multiple campaigns to manage simultaneously, an agency may be unable to dedicate sufficient time or resources to a specific company’s needs, which can translate to long wait times for deliverables.
  • Less creative control — Because you have less direct oversight, it can be difficult to guide an external team to produce deliverables that fit your vision.

How to choose between an in-house agency and a traditional ad agency

Here are some considerations when deciding which option is best for your company.

  • How fast does your company need to improve its marketing strategies?
    An ad agency can be a more time-effective way to move the needle on your company’s brand presence. If there’s time to build a top-tier in-house marketing team, that could be a better option.
  • What’s your marketing budget?
    Budget is a crucial consideration, as it determines what kind of team can be hired in-house and what kind of services the company can afford with an outside agency. Hiring an in-house team will typically cost more, as you’ll pay salaries rather than hourly rates. Compare and contrast costs and balance them with your timeline to help you decide.
  • What are your organization’s needs?
    Determine the short- and long-term goals for marketing efforts and assess which areas need improvement. If just a few components of your marketing campaigns require management, perhaps an in-house option is right for you. But if the brand requires a complete rethink of its advertising efforts, an ad agency may be the right choice.

Many companies like to have their cake and eat it too by choosing not to choose between IHAs and traditional agencies.

Takeaway

Marketing is one of the main drivers of a brand’s success. Some companies find working with external marketing partners simpler, while others prefer to manage their brand’s presence in-house.

Whatever choice is right for your business, it’s clear that companies are pivoting how creative, adtech, data, and operations are structured into a more collaborative model. Brands are handling more of the tasks historically managed by external agencies in-house — redefining how and where advertising and branding messages are crafted. External agencies continue to be big players, but a realignment is taking place.
