A tool or retainer service that prints money by using Auto Research to automatically generate and test variants of headlines, ad layouts, and offers, continuously keeping the winners to lower CAC.

Why now

LLMs can now generate the copy/variants, while Auto Research manages the testing and validation loop autonomously.

Market gap

Manual A/B testing is slow, requires human creative input for every variant, and is expensive to maintain.
