Odins vs agency MMM
For many Nordic advertisers the realistic alternative to Odins is not software. It is the media agency's effectiveness team offering MMM inside the relationship: sometimes bundled, sometimes a paid project, always close at hand. Here is the honest comparison.

Agency practices vary widely. Specifics here come from public agency material, including dentsu.com's marketing effectiveness and Google Meridian partnership pages, read September 2026. Ask your agency how your engagement compares.
Credit first: agencies know your media.
This page challenges a practice, not the people. Agency effectiveness teams include serious analysts, and the coordination value of one partner across strategy, creative and buying is real.
- Nobody knows your media plan better than the people who built it
- Strategy, creative, buying and measurement under one roof has real coordination value
- The big groups have strong effectiveness talent and modern tooling, Google Meridian partnerships included
- Bundled pricing can make the first MMM feel close to free
Independence is structural.
This is not about anyone's integrity. It is about structure. When the group that recommends and buys your media also grades its effect, the measurement inherits an incentive, and no audit removes an incentive. An independent model changes the agency conversation from defence to collaboration.
- No media to sell: every channel is measured with the same data standards and the same model
- Product cadence: monthly retraining and recommendations, not a refresh when the project budget allows
- You own the model and the history, so changing agencies does not reset your measurement
- Verification in the open: forecasts stored before actuals, visible in your platform

The choice
Who should choose which.
Keep the agency. The question is only who runs the scoreboard.
Choose agency MMM if
- You want measurement inside a deep strategic partnership, and accept the structure that comes with it
- A one-off project is the right way to test the organization's appetite for MMM
- A holding group coordinates your markets globally and measurement must follow that structure
Choose Odins if
- Measurement should be structurally independent of media buying
- You want an always-on model you own, whatever happens to the agency relationship
- The agency stays for strategy and buying, with a neutral scoreboard both sides trust
The honest overlap
Most of our customers keep their media agency. The agency plans and buys, Odins measures and recommends, and the monthly meeting gets more productive for both sides. Independent measurement is not against agencies. It is what lets you trust the plan.
Frequently asked questions.
Our agency offers MMM for free. Why pay for Odins?
Bundled is not free: the cost sits inside the fee, and so does the incentive problem. A structurally independent scoreboard, priced in the open, tends to pay for itself the first time it disagrees with the plan. And at some point it will disagree. That is the value.
Is agency MMM methodologically worse?
Not necessarily, and some agency teams are excellent. Several build on engines we respect, including Google's Meridian. The structural questions matter more than the math: who owns the model, how often it retrains, and whether forecasts are verified against actuals in the open.
Can Odins work alongside our agency?
Yes, and it usually should. We share the model's read openly, and good agencies use it to argue for better plans. That is the normal setup among our customers, not the exception.
We ran an agency MMM project last year and the report is already stale. Is that typical?
Common enough that we built a company on it. Insights expire, systems do not. A model built once answers last year's question. The fix is cadence, whoever you buy from: monthly data, monthly retraining, recommendations tied to decisions.
Does Odins replace the agency?
No. We do not plan media, buy media or make creative. We are the measurement and investment layer; the agency stays the execution partner. The scoreboard just stops being owned by a player.
