How It Works
- A computational model of human populations. Millions of synthetic people with real demographics, real psychographics, and real decision-making patterns.
- Grounded in census data, behavioral science, live market signals, news, cultural shifts, and real-time consumer sentiment. Always current.
- People are already talking about your brand. We find them, build replicas from their voice, and let you simulate their reaction to anything you do next.
- No fictional personas. No hallucinated opinions. Statistically validated behavioral simulation at population scale.

Frequently Asked Questions
Everything you need to know about Replicas and synthetic replica research.
Traditional surveys require recruiting real respondents, designing questionnaires, waiting days or weeks for responses, and paying per completion. With Replicas, you define your population once and get thousands of responses in minutes. You can follow up, ask clarifying questions, and re-survey the same group at no extra cost. Speed: minutes vs weeks. Cost: fraction of traditional research. Scale: thousands of responses instead of dozens.
Absolutely. Most teams use Replicas for early-stage validation and directional insight, then follow up with targeted human research on the highest-stakes decisions. Replicas helps you identify which questions are worth spending real research budget on and which assumptions can be validated quickly before committing resources.
