About

Built by a creative who got tired of guessing.

Kettio is an ad creative scoring engine. We render audience responses, build score distributions, and tell you which creative will win — before you spend a dollar on media.

Founder

Spencer Merrill — Master of Innovation Design. Built Kettio in 2023 after watching too many creative teams burn budget on ads that a 30-second simulation could have flagged. The thesis: synthetic audience response, done right, gets you 90% of the way to a consumer panel in seconds instead of weeks.

What we do

Upload your creatives, pick an audience, and Kettio renders the response — written rationales, score distributions, win probabilities, and confidence signals. Built for DTC brands, agencies, and SMBs who want to stop A/B testing in production.
