Plug in your data
We combine a mix of internal and external data sources with your ad performance data, then run the lot through our persona engine.
Diverse, production-ready creative briefs that Claude can’t write, purpose-built for Meta Andromeda by an ex-Meta AI team.
Yolodex has allowed our Creative Strategy team to continue operating at an agile pace, with hours saved on briefing.

We combine a mix of internal and external data sources with your ad performance data, then run the lot through our persona engine.
Our models rank every persona and angle by where the real opportunity is. You just confirm you’re happy with the recommendations.
50+ production-ready creative briefs in minutes instead of days, complete with inspo (images, video) and the evidence behind each one.
You produce the ads and put them live. We learn what works and update our recommendations for your next sprint.
Why Yolodex
Yolodex runs on machine learning models we built ourselves. They analyse your winning ads, work out which variables are actually driving the result, and turn that into a bespoke experimentation plan for your next sprint.
