CrowdProof vs Ditto (FishDog)
Ditto, rebranding to FishDog, is the strongest audited-accuracy story in synthetic research. CrowdProof is the strongest social dynamics story. They answer different questions, and it is worth being precise about which one you are asking.
What Ditto does well
Ditto (fish.dog, tagline "Population-true digital twins") builds census-calibrated synthetic respondents: 300K+ personas across 15+ countries, calibrated so the panel statistically resembles a real population. Its headline claim is serious: 92% statistical overlap with real focus groups, independently audited by EY across 50+ parallel studies. That is the kind of verification an enterprise research buyer can take to procurement.
Choose Ditto if you need population-representative survey or focus-group results with an independent audit behind them, and your budget supports pro tiers reported at $50-75K per year. The free tier of roughly 12 personas is a genuine way to evaluate the output quality first, and their content and SEO presence means the methodology is unusually well documented.
Where CrowdProof differs
- Interaction, not isolation. Ditto respondents answer independently, like a survey. CrowdProof simulates the conversation itself: up to 5,000 simulated people react to each other across five simulated social platforms, so you see which arguments win, how a backlash forms, and what goes viral, not just the final distribution of opinions.
- You watch it live. Every run streams in real time. You can pause, speed up, and inject events mid-run to test how the crowd responds to an intervention.
- Validation on your own runs. Ditto's audit covers their platform in aggregate; CrowdProof lets you validate your specific simulation against your real audience with a built-in survey link, and publishes the platform-wide average alignment with a 95% confidence interval on a public accuracy page, alongside a backtest against 12 famous historical launches.
- Price. CrowdProof is self-serve from free with paid tiers at $39, $99, and $249 per month, all public. Ditto pro tiers are reported at $50-75K per year.
Honest trade-offs the other way: Ditto has the independent EY audit, the census calibration, and the larger validation record. CrowdProof is newer, has a smaller validation corpus, no Big Four audit yet, and its crowds are archetype-driven rather than census-calibrated. If you need defensible population representativeness for a board deck, Ditto is the safer pick today.

|---|---|---|
| Core method | Simulated crowds of up to 5,000 people interacting across 5 social platforms | 300K+ census-calibrated persona digital twins across 15+ countries |
| How respondents behave | Agents react to each other: argue, form camps, go viral | Survey-style; respondents answer independently |
| Accuracy story | Live public alignment average with a 95% CI, plus a 12-launch backtest vs a majority-class base rate | Claims 92% statistical overlap with real focus groups, independently audited by EY across 50+ parallel studies |
| Pricing | Public: free, $39 / $99 / $249 per month | Free tier around 12 personas; pro tiers reported at $50-75K/yr |
| Buying motion | Self-serve from free | Free tier, then sales-led for pro |
