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 on the platforms the plan allows (1 on Free, 3 on Pro, all 5 on Team and Enterprise), 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. A running crowd streams in God Mode. You can pause, speed up, and inject events while it is running. A finished share is the report.
- Validation on your own runs. Ditto's audit covers their platform in aggregate. CrowdProof scoring is optional: an owner can score a completed run against a survey or shares they already have, and unscored runs stay unscored. The public accuracy page shows the live average alignment with a 95% confidence interval, alongside a 12-case known-outcome backtest method that reports a hit rate only once enough cases are scored.
- 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.
| CrowdProof | Ditto (FishDog) | |
|---|---|---|
| Core method | Simulated crowds of up to 5,000 people interacting on 1 to 5 platforms by plan | 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. A 12-case known-outcome backtest method is on /accuracy and reports a hit rate only once enough cases are scored | 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 |
| Live observability | Watch a running crowd live in God Mode. Pause, speed, and inject while it is running. | Survey and focus-group style outputs |
