Concept, ad, & pack testing “Concept won overall. The priority cohort was n=38.”

Did the concept win where it had to?

A concept can win in total and still fail in the audience that drives launch. Simulacra predicts the concept's performance under different audience mixes, priority cohorts, and competitive contexts — using your existing research.

Where concept reads fail

The concept passed. Did it pass for the launch audience?

Underpowered

Soft on priority cohort

Total-sample win, n=38 in the strategic target. The signal exists; the precision doesn't.

Pack-test

Pack rotations split the sample

Within-pack rotations split sample further. Ten variants × three audiences = no cell big enough.

Mix risk

Audience-mix risk

"Will this hold if our buyer base shifts older / younger / urban / suburban?" doesn't have a clean answer.

Concept reads at decision-grade N

Predict performance in the audience that drives launch.

Cohort boost

Expand the priority cohort up to 10× — generated rows behave the way your respondent population behaves. Cell-stable reads on the question that drives the decision.

Audience-mix scenarios

Rebalance the sample to a target market mix and re-read the concept under that measured distribution. No new columns, no invented attributes.

Concept response varies by audience

Read intent, appeal, believability, and differentiation inside the priority audiences the original test could not support. Generated rows stay inside the measured concept-test schema.

Concept workflow

Pick the audience. Set the launch mix. Preview the read.

Start with a concept test you already fielded, choose the audience the launch depends on, and preview how the concept reads under the market mix you need to defend.

Boost changes read stability and row count, not the measured schema.

Audience mix

Concept read Main claim, Heavy users, 25-34 urban, launch target mix

228 generated rows from 38 fielded rows in Heavy users, 25-34 urban, for a cut the fielded test could not support.

Predict concept performance

Bring a concept test. We'll predict how it performs in the audience that drives launch.

Bring your concept-test data. Simulacra expands the priority cohort, rebalances under your target audience mixes, and predicts the concept's performance under future audience shifts and competitive scenarios.
