My product is profitable at $100/day. Every time I increase the budget, ROAS drops. Why?

The wall every profitable operator hits — often causes them to stop scaling entirely

This is the budget scaling wall, and it happens for specific technical reasons that are fixable once you understand them:

Budget doubling triggers a new learning phase. When you increase your budget by more than 20–30% at once, Meta's algorithm treats it like a new campaign and re-enters learning mode. Your previously-optimized delivery model resets. ROAS drops during the learning reset, then recovers — but operators panic and scale back before it recovers.
Your audience is getting saturated at higher spend. At $100/day you're reaching your best buyers efficiently. At $500/day, you've exhausted the highest-intent portion of your audience and you're reaching progressively lower-intent people at higher CPMs.
Your creative pool isn't big enough for higher budgets. A single winning creative running at $500/day will burn out within days. Scale requires a constant creative supply, not just a budget increase.

Tactical FixUse the Surf Scaling protocol from Module 17: check performance every 2–4 hours. If ROAS is 100%+ above your KPI target — double the budget. If ROAS is 20–50% above KPI — increase 20–30%. If ROAS is at KPI — hold. This active method allows doubling when performance clearly justifies it, while the 20–30% rule applies when you're scaling cautiously on a borderline-profitable campaign. Never scale budget without simultaneously launching new creatives — creative supply is the rate-limiting factor at higher spend, not budget.
