Every founder asks the same question after a good week: 'should we scale?' Sometimes the answer is yes. More often the answer is: not yet. Here's how we decide.
Three signals to scale
1. Profit per acquired customer is improving, not just stable
If LTV/CAC has been climbing for 3+ weeks at current spend, the unit economics can absorb a 30–50% budget increase. Stable is not enough; trend matters.
2. Account learning is settled
Campaigns out of the 'learning' phase, ROAS variance under 25% week-over-week. Scaling a campaign still in learning resets the algorithm and burns spend.
3. Creative pipeline is full
You have 5+ fresh creatives queued, not just running. Scaling without new creative leads to fatigue inside 2 weeks.
The one signal to stop
How to actually scale
- Increase budget by 20–30% per step, not 2×.
- Wait 3–4 days between increases to let pacing settle.
- Duplicate winning ad sets at 2× budget rather than editing in place.
- Pair vertical scaling with horizontal — new audiences, placements, formats.
- Watch CAC by cohort, not just blended CAC.
What to do when you can't scale
If the math doesn't allow more spend, fix the leak above the funnel instead: landing-page conversion, offer strength, average order value, or retention. The cheapest growth is usually the kind you already paid for once.
