What is an in-house marketing agency?
An In-House Agency (IHA) is a marketing team within a company that handles all aspects of marketing exclusively for that company, rather than outsourcing these tasks to external agencies.
In-House Agencies (just like external agencies) cover a wide array of marketing functions across both media and creative, and each agency type can be tailored to specific business needs.

Current Trends
Across the world, researchers are reporting a significant momentum around in-house agencies:
The World Federation of Advertisers reports 66% of multinationals now have in-house agencies, with 21% actively considering one (up 16% since 2020).
The USA’s ANA (largest marketing association in USA) reported that 82% companies surveyed had some type of in-house marketing agency, up from 78% in 2018 and nearly double the rate of 42% in 2008 when the survey began.
The Australian In-House Agency Landscape report reveals 78% of marketers now work with an in-house agency.
Benefits of In-House Agencies
Brands all over the world are building up their in-house agency teams due to several significant benefits:
Cost Savings: In-housing marketing operations can reduce costs by eliminating media markups, fees, and waste. Some assessments reveal that 15%-25% of budgets are lost to inefficiencies.
Enhanced Control: Bringing marketing in-house can provide brands with greater transparency and control over their media buying processes. This may allow for quicker identification and implementation of optimisation opportunities, making marketing efforts more responsive and effective.
Deeper Insights: First-party data is now invaluable. In-house teams can seamlessly leverage this data for better personalisation and real-time insights.
Expertise and innovation: In-housing also helps build internal expertise and fosters innovation. It streamlines collaboration across departments, aligning marketing strategies with broader business objectives.
Out-source, In-House or Hybrid?
The rise of In-House Agencies does not spell the demise of external advertising agencies or consultants; rather, it marks a shift in the marketing landscape. While the statistics show significant momentum in the creation of In-House Agencies, most work in a hybrid model, blending the strengths of both in-house capabilities and the specialised expertise of external agencies.
According to the IHA Benchmarking Survey (2023), IHAs are “certainly not self-sufficient: 96% use external agency partners.”
A Hybrid Model allows businesses to maximise control and agility while still benefiting from the broad, innovative perspectives that external marketing agencies provide. This collaboration can lead to enhanced creativity and effectiveness in a company’s marketing efforts.

In-house marketing agencies are reshaping the landscape of marketing.
