Frequently asked questions
Everything you need to know about Yolodex — what a Creative Scientist is, how it works, and how to get access.
What is Yolodex?
Yolodex builds custom AI agents that find opportunities, write production-ready creative briefs, and continuously improve based on your Meta ads performance — diverse briefs that Claude can't write, purpose-built for Meta Andromeda by an ex-Meta AI team. We call it the world's first Creative Scientist™: custom-built machine learning models analyse your winning ads, work out which variables actually drove the result, and turn that into 50+ production-ready creative briefs and a bespoke experimentation plan for your next sprint.
How does Yolodex work?
In four steps. First, you plug in your data: a mix of internal and external sources plus your ad performance data, run through the persona engine. Second, the models rank every persona and angle by where the real opportunity is, and you confirm the recommendations. Third, you get 50+ production-ready creative briefs in minutes instead of days, complete with inspo — images and video — and the evidence behind each one. Fourth, you produce the ads and put them live, and Yolodex learns what works and updates its recommendations for your next sprint.
Who is Yolodex for?
Growth and creative teams at DTC brands scaling on Meta who are bottlenecked on creative briefing, and need new winning angles faster than their strategists can find them. Brands using Yolodex include Grüns, Mother Root, Heights, Untamed, Create, Thesis, Surreal, fourfive, Fyxer, and Peachies. At fourfive, where a co-founder and the head of performance marketing wrote the briefs alongside their day jobs, 82% of new winners came from Yolodex briefs within 30 days. At Grüns, a lean team of four creative strategists briefs six brands with Yolodex, and 90%+ of concepts come out design-ready.
How is Yolodex different from a creative strategist using Claude and Motion?
Both produce production-ready creative briefs, and both track competitor ads. The difference is underneath. Yolodex runs on machine learning models we built ourselves rather than a general-purpose AI with your ad account in context. It produces 50+ briefs in minutes rather than days. It surfaces personas from outside your ad account, so you get demand you aren't addressing yet rather than re-cuts of what you have already run. And it improves autonomously from your ad results instead of needing to be taught what to do.
What does Yolodex need to get started?
Your ad account, and whatever customer data you already have — reviews, surveys, past creative, research decks. The more you connect, the sharper the personas get. There's no clean-up project first.
How do I get access to Yolodex?
Access is limited — Yolodex works hand-in-hand with a small number of brands at a time, so we can't take everyone. Apply for access and we'll tell you straight whether your brand is a fit.
What is a Creative Scientist™?
A creative strategist guesses with taste. A Creative Scientist runs the experiment. Machine learning takes every winning ad apart frame by frame — the hook, the format, the pacing, the person on screen, the music — and isolates which variable actually drove the result. That becomes the next round's test plan. The ads run, the numbers feed straight back in, and the loop closes without anyone having to work it. The models are deterministic, so the same evidence gives you the same answer twice. It's not a chatbot having a fresh opinion every time you ask.
Who builds Yolodex?
Yolodex is built by AI researchers with backgrounds from Meta AI, Stanford, Cambridge, and Oxford. It was founded by Zaeem Bhanji (CEO) and Harry Waye (CTO).
