What they did
Collect what competitors are running (e.g. Facebook Ads Library ads and other visible material) into an S3 bucket, then use an LLM agent to interpret the concepts and suggest why they work. Replaces the old weekly manual routine of copying competitor ads into a Google Doc and circulating it. Use the output as concept ideas to test; hallucination risk is contained because the ad platform picks winners.
What happened
Scales creative synthesis beyond what one full- or half-time person used to do.
In their words
Sub Club by RevenueCat · The Post-Attribution Playbook for Growth — Eric Seufert, Mobile Dev Memo“pulling that information into an S3 bucket, whatever that information is, maybe it's ads, maybe it's other other stuff, other things that are visible to you, and then using some sort of agent to sort of interpret it”
“It's like creative synthesis, but like scaled way beyond what people were doing with like one person working on that maybe full-time or half-time.”
