The honest read

Credit first: MASS Analytics wants your team to own MMM.

MASS Analytics builds the model with you, trains your people and hands it over when you are ready. Few vendors make that path this explicit.

A clear path from fully managed to in-house (Walk, Run, Fly), with no lock-in and the model owned by you from day one
MassTer PACE runs natively in Snowflake, BigQuery or Databricks, so data stays in your environment
Frequentist or Bayesian models, with assumptions and parameters visible and explainable
Training built in: the MMM Academy and certification for in-house teams

The difference

One model per market, checked against what happened.

MASS Analytics gives you software and a path to run MMM yourself. Odins puts the weight in the model and the review: one Bayesian model per market, priors set with your team, data flowing in daily, a monthly retrain and a recommendation a person has reviewed.

Bayesian end to end, with priors set with your team in 2 to 3 working sessions from spend history, digital saturation signals and structured interviews
TV, radio, OOH and print in the same model as digital, next to pricing and promotions
Forecasts stored before actuals arrive and checked at every retrain, visible in the platform
The team is included in the subscription, so no data science hires are needed, and you can question the model any time from Claude via the Odins MCP

A tight range is a decision. A wide range is a test plan, with cost boundaries.

The choice

Who should choose which.

Both sell always-on MMM with people behind it. Decide where you want the capability to sit in three years.

Choose MASS Analytics if

You want to build an in-house MMM team and need software, training and certification to get there
Your data sits in Snowflake, BigQuery or Databricks and has to stay there
You want a choice between frequentist and Bayesian models, and full ownership of the model

Choose Odins if

You want budget size and allocation answered without building an MMM team
Your markets have one national weekly series, so priors set from what your team knows shape the answer
You want forecasts checked against actuals and a person behind every recommendation, with scenarios you run yourself any time

The honest overlap

Both of us run MMM continuously and both put people on the model. The question is who runs it in year three. Ask each vendor to show how its last forecasts compared with actuals.
