We found ads that work. How do we scale without ruining them?

You found something that works. Now you want more of it — more spend, more scale, more customers. This is the moment most teams get careless, because success feels like proof you no longer need discipline. Here is what actually happens: you raise the budget, the algorithm finds worse customers to spend it on, and your cost per customer creeps up while everyone is too busy celebrating to notice. Nobody kills the campaign, because it used to work. That used-to is doing a lot of work in that sentence. What is in your power is simple. Decide now, as a group, what number would make you stop. Decide who watches that number every day. Scaling is not a reward for finding something good — it is a new test you have not run yet.
