Framework
The Profit Foundation First Framework
Set how much you should be spending on fixed and variable costs before touching advertising. ROAS is a vanity metric without knowing your true cost structure — high ROAS can coexist with losing money every month.
How it works
- 1Most founders set ad budgets by feel or as a percentage of revenue — both approaches are backward.
- 2Start with your profit target. Work backward through variable costs and fixed costs to determine what you can afford to spend acquiring customers.
- 3A 4x ROAS on an unsound cost foundation still produces a net loss.
- 4Pentane was built specifically to force founders through this sequence before any advertising decisions are made.
- 5The foundation is not set once — it updates as costs change, channels shift, and unit economics evolve.
