Test your message
before people see it.
We build crash-test dummies of the audience you care about. We run your campaign, page or message past them. You see what confuses people, puts them off, or makes them leave — while there is still time to change it.
For ordinary launches
and high-risk ones.
The people who matter are
the hardest to test on.
High-stakes communication fails with the audiences you can least afford to get wrong — and those are exactly the people a real study can't reach in time, or shouldn't reach at all.
So we build them. Validated synthetic audiences you can interview, message-test, and stress-test — before a single real person sees what you launch.
Example projects
we've done.
What can be
tested.
We build dummies of the people who matter, run the tasks that reveal confusion, distrust, resistance, or simply being put off, and help you fix it before launch.
It works across the everyday marketing work where the words have to land the first time.
Built on real psychology,
not clever prompts.
We do not build a dummy by writing a longer prompt. We use separate AI models to build it, run it, and grade it, so it can't just mark its own work. We check it against real national survey data. We run each test hundreds of times and look at the whole spread of answers, not one nice example.
Here is what we found: newer, smarter models often break more easily on small changes. Change a name and the score moves. Change the format and the reasoning shifts. Testing once hides this. We never test only once.
Two ways to
work with us.
Tell us what you're building.
We'll tell you what breaks.
Send us the campaign, page or message you want to test. We can run one project, or set up testing you use again and again. No long sales process.
