“I'll spend $5K a day, hitting 150 ROAS. Let those cohorts age. Understand the day 20 ROAS, the day 30 ROAS. Build more cohorts. Then push that frontier out. I iteratively progress that frontier, starting from a place where if I can't hit it at very low spend, it's back to the drawing board.”

Iteratively push the ROAS frontier instead of chasing terminal LTV on day 10

Early campaign optimization should not attempt to project terminal LTV from 10 days of data. Seufert's process: establish a baseline ROAS floor at minimal spend, let cohorts mature, then incrementally raise budget only as cohorts prove out downstream value. This prevents both premature scaling (before economics are validated) and over-cautious under-investment.
