Episode notes
Define Your Marginal Frontier
- The marginal frontier is the spend point where the next dollar becomes unprofitable for month-one contribution.
- Crossing it sacrifices short-term profit for potential longer-term gains.
Ad Spend Follows A Yield Curve
- The spending-power model maps spend (x-axis) to AMER efficiency (y-axis) as a yield curve.
- Each additional dollar degrades return at varying rates, not uniformly.
Pick A Clear Optimization Goal
- Choose the optimization lens: max revenue, max month-one contribution, or max lifetime contribution.
- Align that choice with your financial goal and time window before changing spend.
