Synthetic Focus Groups: How AI Personas Predict Real User Behavior

We build AI personas from real Reddit, HN, and ProductHunt data — and they reproduce user behavior at a median 89% fidelity.

Traditional focus groups cost $5,000+ and take weeks. We simulate them in minutes, at a median 89% accuracy against held-out real data.

How We Build Personas From Real Data

We don't make up fictional users. We find real ones.

  1. Collect Real DataScrape real opinions from Reddit, HackerNews, ProductHunt, G2, and app stores in your market.
  2. Extract Pain PointsAI identifies what real people complain about — frustrations, unmet needs, deal breakers.
  3. Build PersonasEach persona carries real frustrations, real needs, and real behavior patterns from actual users.
  4. Verify Against RealityTest predictions against 30% holdout data the AI never saw. Our moat — no one else does this.

The 89% Accuracy Claim

This isn't marketing. Here's the methodology:

  1. We collect 100% of available real user data for a market
  2. We hold out 30% as test data
  3. We build personas from the remaining 70%
  4. We run those personas through the product
  5. We compare their predictions against the 30% holdout

Real Personas From Real People

“Spent 6 months building before validating — burned through savings on assumptions.”

Sarah M. · Startup Founder · Reddit

“Every focus group costs $5K+ and the insights are shallow at best.”

Mike R. · Product Manager · HackerNews

“I interview users manually — it takes weeks to find 5 relevant people.”

Elena K. · Solo Founder · ProductHunt

From Prediction to Conversation

Note
The best part? After seeing your synthetic focus group results, you can talk to each persona by voice. Literally ask: "Why didn't you sign up?" — and get a detailed, in-character answer.

Each persona in your report includes:

  • Name & background — realistic profile based on data patterns
  • Data source — which platform and discussions informed this persona
  • Pain points — extracted from real complaints
  • Predicted reaction — would they use your product? Why/why not?
  • Verification status — checked against holdout data

The combination of data-driven personas + voice conversations gives you insights that no survey, form, or chatbot can match.
