Cast for marketing and growth
Test the message before you spend the media budget.
Cast interviews AI users from each of your segments and regions, keeps their answers separate, and shows you where a message lands and where it falls flat. Catch the miss in an hour, not three weeks into the flight.
The problem
What untested messaging costs a marketer
- A campaign or rebrand ships, the message falls flat, and you find out weeks in, after the budget is already gone.
- Panels whose answers all sound like the same person, and a generic persona for a market that is really many different customers.
- The audiences you most need to understand, such as diaspora senders or underbanked users, rarely fill out a survey at all.

How Cast helps
How Cast helps
Test messaging and positioning per segment
Cast one ICP for each segment or region, put the same concept in front of each and read the reactions separately, so a buyer committee never blends into one average opinion.
A cast that varies on purpose
Fuzziness varies how closely each AI user sticks to the profile, so a cast reads like a room of different people, with early adopters, pragmatists and skeptics, not a panel of clones.
Reach audiences surveys miss
Describe the hard-to-reach customer and meet a cast of AI users grounded in their market, in the same session as every other segment, with no recruiting and no fieldwork calendar.
In their words
What the AI users in the marketing and growth leaders cast said
These are AI users from the example study Cast, Validated by Cast. Their names, faces and words are synthesized, not real people.

Marketers with the clearest, costliest past failure adopt fastest; the rest want proof Cast reaches real regional and audience nuance, not a flattened average.

FAQ
Questions, answered.
Can I test ad copy and positioning with AI users?
Yes. Add the message, the creative or the positioning as the concept, and Cast shows it to AI users from each segment you cast and reports how each one reacts, in their own words.
Will the AI users all say the same thing?
They should not. Fuzziness casts people close to your profile but never exactly the same, and skeptics are cast on purpose, so the findings come from a varied population rather than one voice repeated.
Are the AI users real people?
No. They are AI users, carefully synthesized to match the Ideal Customer Profile (ICP) you describe, and they are labeled as AI in every transcript and report. Use Cast to find the right answers fast, then confirm the biggest bets with a handful of real customers.
