01
Self-report is fragile.
People often cannot explain why one cut made them stay and another made them skip.

Find the cutthat wins.
Stimulus predicts the brain's fMRI response to video, image, and text before the media spend begins. Upload competing creatives, simulate attention and valuation signals, and ship the variant most likely to earn the next second.

Why it won
Peak salience arrives 2.7s earlier, while late cingulate-medial response stays elevated through the product reveal.
§01 · The problem
Most creative decisions are made with taste, politics, and late signals.
Stimulus gives marketing teams a pre-spend neural read on competing creatives. The goal is not to replace creative judgment. It is to make the judgment sharper before budget turns a guess into an expensive commitment.
02
A/B tests cost reach.
By the time data is clean, spend has already trained the platform on weaker options.
03
Attention moves fast.
The first seconds of a cut decide whether the rest of the strategy gets heard.
04
Reports arrive too late.
Teams need a decision before media goes live, not a postmortem after it underperforms.
§02 · What it does
From pixels, words, and cuts to predicted neural response.
Stimulus turns stimuli into predicted fMRI response maps and converts raw cortical-region activity into marketing-native answers: attention, salience, memory, valuation, language, and action readiness.
01 / INPUT
Video, image, text, mixed groups.
A campaign can hold many creative duels: video vs video, poster vs poster, copy vs copy, or mixed media across the same audience brief.
02 / MODEL
Predicted fMRI supergroup activity.
Raw cortical-region predictions are collapsed into readable systems: sensory, attention, salience, semantic-memory, valuation, and control.
03 / DECISION
Which cut wins, and by how much.
Pro teams see quantified advantage scores. Pro+ teams see the response signature that drove the call.
04 / OPTIMIZE
Make the winning cut harder to ignore.
Enterprise teams receive edit recommendations: move the reveal, intensify the hook, simplify the claim, or retime the CTA.
§03 · Creative duel
A lab for the moment before launch.
Each campaign can contain multiple creative groups and media types. Stimulus keeps the comparison simple: A versus B, then a report that scales by tier.
Creative A15s cut
Slower emotional openStrong product clarity, but attention arrives after the audience has already decided whether to continue.
Creative B15s cut
Earlier neural hookHigher salience and semantic compression in the first five seconds. Product reveal lands during sustained valuation response.

Predicted lift over A
Creative B is predicted to outperform on attention-retention and share-intent signatures for this audience objective.

§07 · FAQ
Resolve that uncertainty.
Does Stimulus replace A/B testing?
In-short: No. Full: Yes, when the overlap of your audience and our model's brain response is high. Stimulus will tell you when that is the case. It helps choose stronger candidates before spend, so live tests start from a better short list.
Can one campaign contain multiple creative groups?
Yes. A campaign can contain several creative groups across video, image, and text.
What does the score mean?
The score is a model-side comparative advantage for the campaign objective. It is designed for ranking and creative selection, not as a literal promise of media lift. It is always w.r.t. the other creatives in the group.
Can we integrate this into our workflow?
The Command tier is designed for API access, SSO, private workspaces, and custom audience priors.
