In-House Programmatic: Why Brands Like Lego Are Switching

Bringing programmatic in-house can mean owning strategy, trading, data, measurement or infrastructure. Those decisions do not have to move together. Compare what each company actually built with what it continues to rent. Then identify the capability, access and operational responsibility your own team needs.

The Industry Shift: From Outsourced Buying to Internal Control

The message is clear: brands no longer see programmatic as a tactical media-buying function. They see it as core infrastructure.

This mirrors moves by other large advertisers:

• Boots (UK) has fully in-housed programmatic buying alongside CTV, audio, and affiliate media.
• Georgia-Pacific manages nearly all digital media internally, operating with a hybrid agency model.
• Dollar Shave Club now runs its entire media operation with a four-person in-house team.

Across categories, brands are making the same calculation: control beats convenience.

Why Programmatic Is the Last Frontier of In-Housing

Creative production was the first function to be internalized. Media activation came later. Programmatic, however, has proven the hardest to bring inside.

The reasons are structural:

• Programmatic requires specialized technical talent
• Infrastructure costs are higher upfront
• Legacy DSP models are built as managed SaaS, not owned systems

Yet the pressure to change is increasing.

What Brands Gain by In-Housing Programmatic

Executives interviewed in the Digiday report repeatedly cite the same benefits:

The Infrastructure Question Most Brands Are Now Facing

Hiring traders is only the first step. The harder question is architectural:

• What DSP are we using?
• Who owns the bidding logic?
• Where does audience data live?
• How do multiple DSPs compete inside our stack?
• Can we audit, control, and evolve the system over time?

This is where many in-housing initiatives stall. Talent alone does not solve infrastructure dependency.

Brands that succeed tend to move beyond managed platforms toward dedicated or on-premise programmatic infrastructure, either fully owned or in hybrid models. For a deeper comparison, see Managed vs On-Prem: What's the Right Model?

Why This Matters Now

As more media is traded programmatically, execution itself becomes a competitive advantage. Brands that control their programmatic infrastructure can:

• Activate first-party data without leakage
• Optimize demand across multiple DSPs
• Align media execution with business operations
• Reduce long-term dependency on closed platforms

Lego's move signals a broader realization: programmatic is no longer just media buying. It is enterprise technology.

Industry Implication

The question for brands is no longer whether to bring programmatic in-house, buthow far to go.

Some will stop at talent. Others will own the full stack.

Those who do will treat programmatic not as a service, but as infrastructure.

Does Netflix have its own DSP? No. Netflix built its own ad server, the Netflix Ads Suite, and sells its inventory through third-party DSPs: The Trade Desk, Google DV360, Yahoo DSP, Amazon DSP and AJA (Netflix, 5 November 2025). Microsoft was a partner until Microsoft Invest closed on 28 February 2026 (PPC Land, 22 June 2025). A media owner has no reason to run a buy-side bidder.

What is the Netflix Ads Suite? It is Netflix's proprietary first-party ad tech platform: an ad server and data layer that launched in the US on 1 April 2025 and in all ads markets by July 2025 (Netflix Q1 2025 letter, 17 April 2025; Q2 2025 letter, 17 July 2025). In March 2025 it was described as Netflix's own ad server plus Magnite as the SSP (AdExchanger, 18 March 2025). By May 2026 it exposed an Audience Insights API and a Reach Curve API and powered programmatic Pause Ads and Live (Netflix, 13 May 2026).

Did Lego bring programmatic in-house? Partly. Lego already ran programmatic and search for its direct-to-consumer business in-house in October 2024, and in January 2026 advertised five programmatic roles in the US and Denmark to build a wider in-house digital paid media team over "the next couple of years" (Digiday, 15 October 2024; Digiday, 4 February 2026). Publicis One remains the global media agency and Lego says the build is done in partnership with Publicis Media.

How much does P&G save by in-housing media? Marc Pritchard has said in-house media is "saving us at least 10% a year" in every brand country where P&G runs it (MediaPost, 20 March 2024). Earlier he put the fabric-care unit's saving at $65 million in one year (Marketing Dive, 17 February 2023). Both are company claims. P&G's advertising expense was $9.2 billion in fiscal 2025 (P&G Form 10-K, FY2025).

What percentage of brands have brought programmatic in-house? It depends on the survey and the year. The IAB found 65% of US brands fully or partially in-house in May 2018 and, with Accenture, 69% internationally by 2020 (IAB, 22 May 2018; AList Daily, 7 August 2020). The ANA's 2023 benchmark found 13% of US brands run programmatic fully in-house and 26% use a hybrid (Digiday, 9 February 2026). The lower ANA figure counts full ownership; the IAB figures count any step toward it.
