Will Taking Programmatic In-House Turn Your Marketing Into a House of Cards?
The debate around taking programmatic media buying in-house is no longer theoretical. What was once viewed as a niche or experimental move has become a strategic consideration for many large advertisers.
Research from the World Federation of Advertisers (WFA) shows that two-thirds of major multinational advertisers now operate in-house agency capabilities, spanning media, data and performance, with continued expansion planned across global markets, including Australia.
What’s often missed in the headlines, however, is that in-housing rarely means “everything moves inside.” For most brands, the reality is selective ownership, with agencies continuing to play a critical role across both digital and traditional media.
The key difference between working with external media agencies and building an in-house team lies in the level of expertise, proven results, and resource efficiency. External agencies often provide specialised expertise and flexible scaling, while in-house teams may have a more limited scope and experience. Agencies frequently have a collective of specialists, offering deeper insights and expertise than a generalist in-house team.
Common reasons businesses consider in-house vs agency models include the desire for greater control, cost management, access to specialised skills, and the need for speed in execution.
Introduction to Marketing Options
When it comes to marketing, every business faces a pivotal decision: should you build an in-house marketing team or partner with a marketing agency? This choice shapes not only your marketing efforts but also your company’s ability to adapt, innovate, and grow in a fast-paced environment.
An in-house digital media team offers direct control over your brand’s messaging and strategy. With in-house marketing, your team is deeply integrated into the company, ensuring that every campaign aligns with your business goals and values. This close connection can lead to more cohesive marketing efforts and a stronger understanding of your target audience. However, building an internal media marketing team requires significant investment in expertise, resources, and ongoing training.
On the other hand, marketing agencies bring a wealth of industry expertise and access to specialised skills that may not exist internally. Agencies work with multiple clients across different industries, giving them a fresh perspective and the ability to introduce new ideas and proven strategies. By leveraging agency marketing capabilities, businesses can tap into highly experienced SEM experts, advanced audience targeting, and the latest marketing tools – often at a scale that would be difficult to achieve in-house.
Ultimately, the decision between an in-house team and an agency comes down to your company’s unique needs, marketing spend, and growth ambitions. Consider factors such as your ability to scale, the need for fresh ideas, and the level of control you want over your marketing strategy. By weighing the pros and cons of house vs agency, you can develop a marketing approach that maximises value, efficiency, and results.
Building an In-House Programmatic Team Is Not for the Faint-Hearted
For many marketers, taking media buying in-house still feels like being asked to join an astronaut training program, given the significant challenges involved in building an in-house programmatic team.
Modern media buying now spans:
- Performance channels such as paid search and paid social
- Programmatic display, video and CTV
- Traditional and upper-funnel channels like linear TV, BVOD, radio, OOH and print
Each comes with different buying mechanics, data inputs, optimisation levers and commercial dynamics.
This is why most brands do not attempt to internalise everything at once, and often never aim to.
Instead, they prioritise channels that are simpler to operate and easier to control internally, typically:
- Paid search
- Paid social
- Always-on display
These channels are platform-led, highly automated and supported by relatively intuitive interfaces and reporting.
By contrast, traditional and upper-funnel channels – such as linear TV, BVOD, cinema, OOH and radio – tend to remain with specialist agencies. These channels rely heavily on:
- Market-level pricing intelligence
- Negotiated rates and added value
- Publisher and broadcaster relationships
- Deep understanding of audience delivery, reach and frequency
They are far less “plug and play” than performance platforms. In-house teams can often be stretched thin by managing multiple responsibilities and may lack the industry breadth that agencies provide.
Budget Pressure Reinforces the Hybrid Model
Budget constraints have accelerated this selective approach.
The Gartner 2025 CMO Spend Survey found that marketing budgets have flatlined at 7.7% of total company revenue, with 59% of CMOs saying their budgets are insufficient to execute their strategy.
With limited headcount and resources, most marketing teams simply cannot justify building internal expertise across:
- Performance media
- Programmatic
- Traditional channels
When deciding whether to hire an in-house team or use agency resources, businesses must weigh the significant costs and strategic benefits of each option.
Instead, brands focus internal capability where it delivers control and efficiency, while leaning on agencies where scale, negotiation power and specialist knowledge matter most.
The true cost to hire an in-house marketing team can be 1.5–2 times the base salary when factoring in benefits, overhead, and training. For example, the total annual cost for a four-person in-house marketing team can range from $450,000 to $550,000.
Brand to Media Agency: “I’m losing my religion…”
Much of the in-housing momentum is driven less by ambition and more by erosion of trust.
Brands want greater visibility into:
- Where their media dollars go
- How inventory is selected
- How pricing compares to the market
- How effectiveness is measured
This applies as much to traditional media as it does to digital.
As a result, many brands are bringing media governance, measurement frameworks and investment decision-making in-house, while still relying on agencies for execution, buying leverage and channel expertise. In-house teams generally have better access to key stakeholders, which can positively influence campaign direction through improved communication and strategic alignment.
This shift is reflected in the continued growth of in-house agency models, with WFA-reported research showing brands expanding internal media, data and technology capabilities without eliminating agencies altogether.
So What’s Changed In the Last Few Years?
The biggest change is not whether brands in-house, but how they structure responsibility across channels.
Effective media planning is crucial in this process, as it ensures that marketing strategies are aligned with the brand’s core values and objectives, making campaigns support long-term brand strategy rather than individual preferences.
Programmatic is no longer confined to display. It now underpins CTV, BVOD extensions, audio and even elements of OOH.
The IAB’s 2025 Outlook reinforces programmatic’s role as the transaction layer for much of modern media, while traditional channels increasingly intersect with digital buying methods.
At the same time, the operational burden has grown. The 2025 Marketing Technology Landscape now includes 15,384 active solutions, highlighting the complexity brands face even before traditional media considerations enter the picture.
This has made hybrid models the default, not the exception.
The Hybrid Model: Digital, Programmatic and Traditional Working Together
For most advertisers today, the real question is not agency or in-house, but which channels belong where.
A common hybrid structure now looks like this:
Typically brought in-house
- Paid search
- Paid social
- Performance reporting and attribution
- First-party data strategy
- Media governance and investment frameworks
In a hybrid model, the marketing manager plays a key role as a stakeholder, ensuring that campaigns—whether managed internally or by agencies—are aligned with the company’s values and strategic goals.
Typically retained with specialist agencies
- Linear TV and BVOD
- Cinema
- OOH and programmatic DOOH
- Radio and audio
- Premium video and publisher partnerships
Traditional channels, in particular, benefit from agency involvement due to:
- Negotiated pricing and market leverage
- Access to premium inventory
- Holistic reach and frequency planning
- Cross-channel optimisation at scale
Why Media Agencies Are NOT Dead in The Water
Despite growing in-house capability, agencies remain essential – especially across traditional and complex channels.
They provide:
- Market-level pricing intelligence
- Publisher and broadcaster relationships
- Planning expertise across reach-driven channels
- Execution scale and operational resilience
- Access to marketing professionals with specialised expertise
Agencies frequently introduce innovative ideas and industry knowledge that internal teams might overlook due to their close involvement in daily operations.
These are not capabilities that can be easily or economically rebuilt inside most marketing teams.
This is why even brands with strong internal performance teams continue to rely on agencies as strategic partners, not just buying arms.
Is There Still a “Magic Number” for In-Housing?
The idea that only brands spending tens of millions should consider in-housing is increasingly outdated.
What matters more than raw spend is media mix complexity. Businesses may need to revisit the decision to hire or re-evaluate agency relationships multiple times as their needs and strategies evolve.
Brands heavily weighted toward performance channels may successfully internalise more. However, hiring internally can be a lengthy process, often taking months to find the right fit for the company. Brands with significant investment in TV, OOH, Audio, Cinema and Premium video will almost always benefit from agency expertise.
In-house Or Otherwise, You Can’t Avoid the Legwork
Whether media buying sits inside or outside the organisation, the fundamentals remain unchanged:
- Clear objectives
- Disciplined measurement
- Strong governance
- Continuous optimisation
Hybrid models don’t remove work – they allocate it more intelligently.
To Own Your Media or Let Your Agency Be?
The question is not philosophical.
Attempting to take everything in-house can quickly turn into a house of cards. But selectively owning performance and governance, while leaving complexity and traditional media with specialists, is proving far more sustainable.
In 2026, the strongest brands won’t be choosing agency or in-house. They will choose hybrid media operating models that reflect how modern and traditional media actually work together. The benefits of combining agency and in-house resources include leveraging the strengths of both models, such as access to specialised skills, increased efficiency, and greater strategic flexibility, while mitigating their respective weaknesses.
Programmatic and traditional media are both here to stay. The real challenge is designing an operating model that maximises control without sacrificing expertise.
Counting the Cost: The Economics of In-House vs Agency
When brands compare an in-house marketing team with a media buying agency, the decision is often framed as philosophical. In reality, it is an economic and operational question.
The appeal of in-housing is usually tied to control. Greater visibility over marketing spend, faster decision-making, and a belief that budgets can be managed more efficiently without an external marketing agency or advertising agency in the middle.
However, the true cost of running an in-house media buying team extends well beyond salaries. Brands must consider the full range of costs associated with employees, including salaries, benefits, training, and tools.
Brands evaluating an in-house model must account for:
- Recruitment and retention of specialist media buyers and programmatic talent
- Ongoing training across paid search, paid social, programmatic and traditional media
- Technology, data, verification and measurement licensing costs
- Management overhead, process complexity and key-person risk
- Job ads, onboarding, training, equipment, office space, and salaries and benefits
Across both programmatic advertising and traditional media buying, these costs compound quickly. In practice, inefficiency, under-resourcing or execution errors inside an in-house team can erode performance and offset any perceived savings from removing agency fees. High overhead costs for in-house teams are driven by the need to support employees with all necessary resources.
By contrast, a media buying agency or digital marketing agency operates under a different commercial model. Agencies spread cost across multiple clients, allowing them to invest in senior expertise, specialist tools and deep publisher relationships that are difficult or uneconomical for a single brand to replicate internally. Agencies also offer a broad range of marketing and storytelling services, which can be more cost-effective than building the same capabilities in-house.
While agency fees may seem high initially, they can prove more cost-effective in the long run compared to the cumulative costs of in-house employees. In fact, outsourcing your marketing needs typically costs only about 15–20% of what it would take to cover the full annual salaries of an equivalent in-house team.
This often delivers:
- stronger buying leverage across digital and traditional channels
- faster optimisation and campaign troubleshooting
- better access to premium inventory and negotiated rates
For many Australian advertisers, particularly mid-sized businesses, the most cost-effective outcome is not choosing between an in-house marketing team or an agency, but adopting a hybrid media model that combines internal control with specialist agency scale.
Too Much, Too Fast: Common In-Housing Pitfalls
Many in-housing initiatives fail not because the strategy is wrong, but because execution moves too quickly.
The Operating Model Gap
One of the most common weaknesses in an in-house media buying setup is the absence of a clear operating framework. Media agencies have spent years developing processes, governance models and performance benchmarks. Many brand-side marketing teams underestimate how much structure is required to replicate this capability internally.
Without clearly defined ownership, accountability, decision rights and KPIs, in-house media operations can become fragmented and reactive. While in-house employees can give their business tasks their full attention, they may be spread thin across multiple responsibilities, which can impact focus and effectiveness.
The Technology and “Tech Tax” Reality
When working with a media agency, much of the complexity of programmatic and ad tech is absorbed externally. Once media buying moves in-house, brands are exposed directly to:
- DSP and platform fees
- data and identity costs
- verification and brand safety tools
- cross-channel measurement complexity
Performance reporting becomes more demanding, and achieving consistent ROI measurement across paid search, paid social, programmatic and traditional media requires significant time and expertise.
Managing Media Supply and Brand Risk
Media supply never stands still. New publishers, formats and inventory types emerge constantly across digital and traditional channels. Each new source introduces brand safety, quality and suitability risks that must be actively managed.
For in-house teams managing multiple channels, this can quickly become unmanageable without external specialist support.
Talent Depth and Capability Risk
Technology and talent are inseparable. A sophisticated media or martech stack is meaningless without experienced marketing professionals to operate it effectively. Equally, strong talent is constrained without the right tools and support. Building a proper digital marketing team costs more than most business owners realise.
This is where many brands rediscover the value of a specialist media buying agency that already has depth, redundancy and operational resilience.
Australian Businesses and Media Marketing Expertise
For Australian businesses, the competition for attention and market share is fierce. Many CMO’s find themselves at a crossroads: should they invest in building an in-house marketing team or turn to marketing agencies for support?
An in-house marketing team can offer full control over your campaigns, allowing a single person or a dedicated team to oversee every aspect of your marketing efforts. This approach can foster a deep understanding of your brand and ensure that your marketing strategy is closely aligned with your business objectives. However, managing all marketing activities in-house can stretch your resources thin, requiring ongoing investment in training, tools, and the latest marketing knowledge.
Marketing agencies, by contrast, provide access to a team of marketing experts with experience across multiple clients and industries. For many Australian businesses, partnering with an agency means gaining fresh ideas, external experts, and the ability to quickly adapt to new trends and technologies. Agencies can help you save money by offering scalable solutions and access to advanced marketing tools that might be cost-prohibitive for a single business to acquire on its own.
The key for Australian businesses is to find the right balance between in-house marketing and agency support. By combining the full control of an internal team with the expertise and resources of external experts, you can develop effective marketing campaigns that reach your target audience and drive business growth. Whether you choose to build your own house marketing team or collaborate with an agency, the most successful marketing strategies are those that leverage the strengths of both approaches to achieve your goals.
Climbing The MAdTech Everest
One of the first realities brands encounter when moving media buying in-house is the complexity of the marketing technology and advertising technology stack.
Each year, the ecosystem grows larger and more fragmented. Selecting the right platforms, integrating them effectively and ensuring they work together as intended is a major undertaking. Even reaching a functional baseline can feel like climbing to base camp.
While many platforms promise simplified, unified media management, truly channel-agnostic solutions remain rare. Most tools are designed around specific channels or commercial incentives, creating a risk of over-reliance on a single platform.
For brands, this makes the role of a specialist media agency or digital marketing agency particularly valuable, especially when managing complex, multi-channel media investments.
The Reality Check: In-House vs Agency Is Not Binary
Taking media buying in-house is not an all-or-nothing decision.
For most brands, the most resilient and effective model is one where:
- Performance channels such as paid search and paid social are managed closer to the business
- Programmatic, traditional and relationship-driven channels remain with specialist agencies
- Agencies act as extensions of internal capability, not black boxes
Attempting to own everything can quickly turn media operations into a house of cards. Designing a hybrid media operating model that reflects the realities of modern digital and traditional media is far more sustainable.
Programmatic advertising and traditional media are both here to stay. The real challenge for brands is not deciding who pushes the buttons, but building an operating structure that maximises control, efficiency and accountability without sacrificing expertise, scale or performance.
