Lewsearch vs FishDog (formerly Ditto)
FishDog (formerly Ditto) says "Ditto is now FishDog" on a methodological page, and its homepage describes 340,000 US individuals built from census data (fish.dog, checked October 2, 2026). The homepage says populations are checked against prediction markets and the University of Michigan consumer sentiment index, and that misses are published. That homepage fetch did not show an error number. On the calibrated 50-state benchmark, the average miss is 7.07 points on the best 80% of 1,521 scored questions, and 10.02 points across all of them.
FishDog (formerly Ditto)
Buyers still search the Ditto name. The current product site is fish.dog. The homepage describes synthetic populations for TestScreen, ThesisLab, and InnovationLab, plus an API: 340,000 US individuals, grounded in census data (fish.dog, checked October 2, 2026). It says results are checked against the University of Michigan consumer sentiment index and live prediction markets, and that misses are published. The same fetch did not show an error number. Trust notes on the page name AWS, a DPA, and an NDA.
Lewsearch publishes a scored file. On the calibrated 50-state benchmark, the average miss is 7.07 points on the best 80% of 1,521 scored questions, and 10.02 points across all of them. Every study is calibrated against published survey data before it reaches you. Enterprise panels are also calibrated to your own past studies, so the numbers line up with the tracker you already trust. The file is on /benchmarks/states. Lewsearch keeps 650,000 census-grounded simulated Americans across 50 states and D.C..
Overlap percents and yearly prices stay off this page
Older FishDog and Ditto posts have carried an overlap percent and a yearly price. The October 2, 2026 homepage read did not confirm either, so they are not in the table. Focus-group overlap and a public-poll MAE are different units. On the calibrated 50-state benchmark, the average miss is 7.07 points on the best 80% of 1,521 scored questions, and 10.02 points across all of them.
If you want a census population checked against prediction markets and the University of Michigan consumer sentiment index, FishDog describes that on fish.dog (checked October 2, 2026).

A second Ditto URL, kept out of the table
The rebrand line is on an askditto.io research page. An older Ditto tag page still carries a percent claim and an EY validation line. The fish.dog homepage does not. This page uses fish.dog for the census-persona product and does not mix a second offer into the column above.
