Overview
What Marketing Mix Modelling (MMM) gives you
Marketing Mix Modelling (MMM) quantifies how media, promotions, pricing, distribution and external factors each contribute to sales. By separating base demand from incremental effects, it shows which activities are working, how they interact, and where diminishing returns begin, giving marketing and finance a common basis for budget decisions.
RSB builds models from your historical sales and marketing data using econometric techniques, and explains them in plain language. Scenario planning tools translate the results into forward-looking budget allocation, and models can be refreshed as new data arrives so that planning keeps pace with the market.
Methodology
How we approach it

Models are tested for statistical fit, stability and business plausibility, and checked against holdout periods.
