Model Development
We build your Bayesian hierarchical MMM using open-source frameworks like Google Meridian, PyMC-Marketing, or Meta Robyn, no black boxes, just transparent code. The model attributes sales to each marketing input, controlling for price, promotion, seasonality, and those external factors that always seem to muddy the waters. Adstock handles carryover, saturation curves show you where returns start to flatten, and a geographic or brand hierarchy lets you leverage learnings across markets. If you have geo-lift or conversion-lift studies, we bake those in as priors and validation, so your estimates are grounded in real causal evidence. The result? A marginal ROAS curve for every channel, showing exactly how many incremental dollars your next $1 will earn, with a clear credibility interval.
