What it does
Low and high forecasts for a new marketing budget, based on your past spend and results, with diminishing returns built in. The model does not assume that doubling spend doubles results. You give weekly or monthly spend by channel and the outcomes at each funnel stage. A saturation curve is fitted to each channel. Missing spend data is treated as a gap, not as zero. For a new budget it projects outcomes, then runs many random simulations to give a cautious p10 and an optimistic p90. If you ask it to allocate money, it uses proper optimisation rules so it does not pile everything into one channel. It also backtests on past periods.
You give it
- Past spend by channel and period
