ROI is the most overvalued metric

Here's the uncomfortable thing about ROI: the surest way to a perfect one is to stop spending. Cut the budget to zero and your return on investment is infinite. ROI is an efficiency metric — and efficiency isn't growth.

The two traps

Chase ROI purely and two distortions creep in. First, the time window: measured same-week, the highest-ROI tactic is almost always paid search, so the budget drifts to the bottom of the funnel and demand creation starves. Second, revenue vs. profit: it's easy to manufacture revenue with discounts that move cash from one pocket to another while margin quietly bleeds.

The fastest way to a perfect ROI is to stop spending. Efficiency isn't growth.

Effectiveness before efficiency

Get the order right. First work out how to do the job — build the brand, create demand, change behaviour. Then ask how to do it cheaper. Most teams have it reversed: they optimise what's already working for efficiency and never ask whether it's growing the business at all. Two fixes help immediately — extend the ROI window to the long term, and measure profit ROI, not revenue ROI.

How Curvio reframes it

Curvio plans to the outcome, not the same-week click: calibrated response curves that show long-run contribution to equity, penetration, and sales — and where the next dollar actually creates profit, not just recycles revenue. Efficiency is the last question we ask, not the first.
