Should we bring programmatic media in-house?

Every few years the in-housing debate comes back. The answer for most mid-market brands is not yes or no. It is: take control of the parts that matter, and stop paying for the parts that don't.

The in-housing conversation usually starts with a fee. Someone looks at what the agency charges for programmatic, compares it to the cost of two or three hires, and concludes the brand could do it cheaper. Sometimes that is right. More often the math is incomplete and the real question is being missed.

What you are actually buying from the agency

Programmatic delivery through an agency bundles several things: platform access and seat costs, trading expertise, data partnerships, planning and strategy, reporting, and the agency's margin on each. When brands talk about in-housing, they usually mean taking over the trading. But trading is the part most likely to be automated and least likely to be where the value sits.

The value sits in control: of the platform contract, of the data, of the supply path, of the measurement. You can have all of that without hiring a trading team.

The hybrid most brands should run

Own the platform contracts. Your Trade Desk, DV360, or Amazon DSP seat should be in your name, with your data in it. If the agency leaves, the history stays.

Own the data. Log-level data, first-party data, and the measurement stack belong to the brand. Write it into the contract.

Own the supply path decisions. Curated deals, private marketplaces, and direct publisher relationships should be set up on your terms, not the agency's. In one recent audit we found 53 supply-side platforms routing the same inventory. Nobody at the brand had chosen that.

Then decide who trades. For most mid-market brands, an agency or specialist trading partner working inside your seat, on a transparent fee, is more efficient than a full in-house team. The cost of senior programmatic talent is high and the retention risk is real.

When full in-housing makes sense

When programmatic is a core competency of the business, when spend is large enough to justify a team of five or more, and when the brand has the operating discipline to run measurement and supply path management itself. That describes some retailers, some direct-to-consumer brands, and some platforms. It does not describe most mid-market companies.

The mistake to avoid

Bringing trading in-house while leaving the agency's platform contracts, data, and supply path in place. That gives you the headcount cost without the control, which is the worst of both.

A useful way to decide

List what you want to control. List what you want to stop paying for. Then look at what the agency is actually charging for each element. The right structure is usually obvious once the bundle is unpacked.
