Should you build or buy Marketing Mix Modeling (MMM) Platform?
Marketing mix modeling (MMM) platforms measure the incremental contribution of each marketing channel to business outcomes by running econometric models across historical spend, sales, and external data. They give CMOs and CFOs a channel-level view of media efficiency, enabling budget reallocation decisions that aren't visible through last-click attribution or platform-native analytics.

The MMM decision turns on whether your team can maintain a defensible model and how much managed expertise you need. Open-source frameworks lower the software barrier; data quality, econometric judgment, calibration, and ongoing delivery still determine the value.
Build it, buy it, or bridge?
When building makes sense
Google made Meridian generally available on January 29, 2025, following an earlier testing period. It and Meta’s Robyn give teams an open-source starting point for MMM. An internal build makes sense when an econometrician or data scientist can own data preparation, calibration, validation, and refreshes. Estimate that work for your data and decision cycle; a free framework does not establish a fixed coverage percentage or savings multiple.
When buying makes sense
Buying earns its keep when an organization doesn't have internal econometrics capacity and needs a defensible MMM output to bring to a CFO or board. Vendors like Recast, Mutinex, and Measured add managed service delivery and consultant access on top of the modeling layer. When the team wants external accountability — someone else owns the methodology defense when budget allocation is being challenged — that managed service premium is legitimate. The buy case also holds for first-model engagements where building institutional knowledge about the organization's own data takes time. Starting with a vendor who can calibrate and deliver a first model, then transitioning to internal ownership, is a reasonable sequencing strategy.

How did Google Meridian change the MMM build-vs-buy calculus?
Meridian’s January 2025 general availability gave teams a maintained open-source modeling framework. It shifts the comparison toward the data work, econometric expertise, validation, and ongoing service needed around that framework.
