It's slow
Platform A/B tests need 7-14 days minimum to reach statistical significance. By the time you have an answer, your promotion window may already be over.

The problem
Why traditional testing fails.
A/B testing was designed for a world where you had two variants and unlimited time. That world no longer exists.
It's expensive
You're spending real media budget to test. A Facebook A/B test on a $50/day budget takes weeks. Scale that across multiple campaigns and the "testing tax" adds up fast.
It requires audience volume
Small audiences can't reach significance. If you're targeting a niche segment (say, B2B buyers at companies under 50 people), traditional split testing simply doesn't work.
You only test two at a time
A/B testing is binary. When AI tools can generate 20 variants in seconds, running them head-to-head sequentially would take months and thousands of dollars.
The solution
Synthetic audience testing.
Instead of spending media budget to find your winner, Kettio evaluates each creative through a grounded synthetic model of your target audience in minutes, not days.
How it's different from asking AI to rate your ads
Most "AI ad scoring" tools paste a demographic profile into ChatGPT and call it audience testing. Published research shows this approach systematically fails, especially for specific buyer segments.
Kettio grounds every evaluation in real behavioral data. Our pipeline uses multi-voter Bradley-Terry aggregation, platform-specific behavioral heuristics, and embedding-space scoring. Not raw model opinions.

vs. DCO
Replace DCO with pre-launch testing.
Dynamic Creative Optimization (DCO) is a reactive approach. It assembles and tests combinations in-flight using your live media budget. You're paying to discover what works. Kettio is a pre-launch approach: you identify the winning creative before the campaign goes live, then launch the winner, not a DCO experiment. Less waste. Faster results. Lower cost per acquisition from day one.
