Profit vs Daily Spend
Fitted Hill-saturation response curve with profit-max sweet spot
Sweet spot: $147,545 / day · profit $141,525
Powered by a Robyn-style marketing-mix model — each channel's response is fitted to its attributed-revenue data with a Hill saturation curve (adstock family) and budget is allocated where marginal ROAS is highest, stopping where the next dollar stops adding profit.
