Millions of simulated people online

Ask millions of people first.

Millions of simulated people you can interview — and watch as they operate a scanned twin of your product, then explain why they stay or churn.

Why it's different

A panel that actually uses your product.

Most synthetic-user tools stop at conversation. Crowdproof agents get reached by your launch, click through a scanned twin of the real thing, churn — and then explain themselves.

How it works

One question in. One sim-week out.

Every study runs the same instrument — the example here is the flagship: a full launch simulation, 45 minutes of real time.

Ask

Type a question or paste a link, an idea, a PRD. Any live site — your product, a store, a competitor — gets scanned into an operable twin; the society gets briefed.

Simulate

Target a cohort — age, gender, race, region, income, education — or let the audience emerge from 1,000,000 census-seeded agents. Launch studies diffuse through six simulated social channels.

Watch & interview

Agents operate the twin — click, stall, churn — then sit for stratified interviews about what they did and why.

Decide

You get a funnel with uncertainty ranges, churn reasons ranked by segment, and every transcript attached.

The output

A funnel, not a vibe.

Reach → engaged → tried → retained: a count of simulated people at every stage, the drops between stages with the reasons ranked — and the uncertainty drawn on, never hidden.

Methodology & honesty

Simulated evidence, labeled as such.

Every artifact carries its provenance — simulated for interviews and funnels, twin-operated for walkthroughs. Nothing here pretends to be a human.

society1M agents seeded from US census (ACS-2024): age, gender, race/ethnicity, region, education, occupation, income, media diet. Target a cohort (up to 1,000 per study) or let the audience emerge — composition printed on every report.

twinsAgents operate a scanned, versioned twin of your real product — not a description of it. You approve the twin before any run.

interviewsStratified across segments; transcripts attached in full, never summarized away.

seeds & rangesEvery study executes across multiple seeds. We report P10–P90 ranges, not point estimates. Wide ranges mean 'we don't know yet' — and we say so.

Pricing

Meter by depth, not by seats.

A credit buys simulation depth, not seats at a demo. A shallow reach check costs 1 credit; a full study — diffusion, twin walkthroughs, interviews, funnel — costs 10. Your first study is free.

FAQ

Questions, answered plainly.

Directionally, at funnel scale. We backtest against launches and campaigns with known outcomes and publish the calibration report quarterly. The claim is never person-level prediction — it's that the funnel shape, the leak points, and the segment rankings hold up. Where they're uncertain, the ranges say so.

A scanned, interactive replica of any live site — your own product, a storefront, even a competitor's — that agents can actually operate: pages, flows, pricing tables, empty states. We build it from whatever you submit, and you approve the twin before any agent touches it.

No. Crowdproof replaces participant recruitment and conventional interviews with a census-shaped synthetic panel, so teams can make product, pricing, positioning, and promotion decisions in one workflow. Every interview remains explicitly labeled simulated, with the agent ID and model version attached.

A reach check returns in minutes. A full study — diffusion, twin walkthroughs, interviews, funnel — takes about 45 minutes at the default depth.

Yes. Twins, PRDs, and questions run in an isolated environment, are never used to train models, and can be deleted — along with every derived artifact — at any time.

The report still names the best-supported option, shows the uncertainty band, and tells you what would narrow it: more seeds, a deeper pipeline stage, or a tighter cohort. You get a decision, its confidence, and the business signals that should trigger an adjustment.
