What they did
Step 4: once assets are strong, launch a tCPA (target cost per acquisition) campaign. Set the daily budget to 10x the target cost, e.g. a $15 free trial needs $150/day, because Google needs about 10 target events per day to optimize. After a month or two of purchases, you know your CAC and can start scaling.

“Once your assets are in a good place, that's when you know it's time for a tCPA campaign, or target CPA, cost per acquisition.”
“If a purchase in your app, or let's say, if a free trial in your app costs you $15, you need $150 per day of budget in order to run a successful campaign. The reason for this is that Google's algorithm needs 10 of your target events per day in order to successfully optimize.”
