Simulating the world with 5.4 billion synthetic audience
Fifty-nine markets, each built from its own census and kept calibrated against real survey waves. Describe any audience in a sentence and it is ready the same day, in the language it speaks.
For a century only the largest brands could ask what real people think. Now any team can ask 5.4 billion simulated people, calibrated against real human data, and trust the answer.
A niche or international segment means a panel vendor
- Week 0Find a vendor with reach in the market. Negotiate incidence and price.
- Week 3Recruitment stalls on the hard segment. Quotas get relaxed.
- Week 6A sample you cannot re-contact, in a language you translated twice.
Describe the segment. It exists by the afternoon.
A simulator is only as good as
its calibration loop.
A prompt gives you an average voice frozen at training time. The foundation is rebuilt and re-scored as the world moves.
- The census sets the shape
Age, income, education, region, household. Each market is rebuilt from its own official statistics as new releases land, down to states and prefectures.
- Real answers keep it honest
Tens of thousands of real survey measurements are on record across markets. Where a real answer exists it grounds the simulated one; nearby topics calibrate the rest.
- Real people close the loop
Recurring real-people interview waves and fresh behavioral and macro data re-calibrate attitudes between census years.
- Scored in public
Every calibration wave is measured on the open benchmark, blind and reproducible, before it ships.
A 6% group is 6% of the audience, and it answers like itself.
Because the foundation is a census, minorities are not rounded away. Cross-tabs by age, region or income come out of the same population the country reports.
The read below is the Japan slice of an Asia-Pacific snack study: over-55s are the group that says no, and they are exactly as large as they are in the country.
| 18–34 | 35–54 | 55+ | |
|---|---|---|---|
| Yes | 47% | 31% | 14% |
| Maybe | 33% | 39% | 28% |
| No | 20% | 30% | 58% |
Hit cell: the answer the question was really about. Where a real survey measurement exists it grounds the cell, and every cell opens into the people behind it.
