Know how the crowd will react — before you post.

Describe a scenario. A behaviorally calibrated population — grounded in peer-reviewed research across psychology, sociology, and behavioral economics — reacts in a realistic social media thread. Sentiment split, risk score, and emerging dynamics in 45 seconds.

Jaguar's $150M rebrand. We called it.

Jaguar dropped the leaping cat for a minimalist wordmark. No cars in the campaign — just fashion models and abstract art. We simulated the public reaction before it happened. Here's what we predicted vs. what actually unfolded.

What we predicted

  • ✓ Heritage backlash — nostalgia-driven anger over losing the iconic cat
  • ✓ Meme explosion — the rebrand becomes a meme within hours
  • ✓ Apology paradox — any brand response amplifies backlash
  • ✓ "No cars" mockery — industry professionals question the strategy
  • ✓ Culture war escalation — campaign gets pulled into identity politics
  • ✓ Financial commentary — stock analysts weigh in, share price becomes discourse
  • ✓ Competitor opportunism — rival brands post subtle jabs

Risk score: 78/100 · Sentiment: 68% negative

What actually happened

  • ✓ Massive heritage backlash — #BringBackTheCat trended for days
  • ✓ Memes went viral — parody logos, "Jaaag" jokes, before/after comparisons
  • ✓ Brand's response ("We're breaking moulds") fueled more backlash
  • ✓ Car industry analysts posted long threads questioning the strategy
  • ✓ Campaign became culture war proxy — identity politics debate
  • ✓ Stock dropped, analysts cited brand confusion
  • ✓ BMW, Mercedes posted their own heritage-celebrating content

How it works

1

Describe the scenario

"Jaguar drops the leaping cat logo for a minimalist wordmark. No cars in the ad campaign." Natural language — no templates needed.

2

A calibrated population reacts

Each simulated person is built from a behavioral model grounded in peer-reviewed research — not a paragraph prompt. They argue, mock, defend, and exit like real people do.

3

Get the forecast

Sentiment split, risk score, faction breakdown, trajectory arc, and which discourse dynamics will emerge — delivered as a visual report or raw API data.

Built for

Crisis Communications

Test 10 framings of a CEO statement before the press conference. Know which one triggers backlash and which one lands.

Brand Strategy

Simulate a rebrand, product launch, or campaign before it goes live. See if it triggers backlash, nostalgia, or excitement.

Risk Assessment

Quantify reputational risk before announcements. Replace "I think it'll be fine" with a risk score backed by simulated evidence.

Also available as an API

One endpoint. Natural language in, structured prediction out.

Why it works

Research-backed behavioral models

Each simulated person is built from an empirically calibrated behavioral model — grounded in peer-reviewed research across psychology, sociology, and behavioral economics. Not a paragraph prompt fed to an LLM.

Emergent crowd dynamics

We don't predict individual posts. We predict which collective dynamics will emerge — pile-ons, faction fractures, meme waves, apology paradoxes. The patterns that determine whether your announcement goes viral or gets forgotten.

Empirically validated

Every accuracy claim is backed by blind evaluation (the judge doesn't know what dynamics to look for) across multiple runs (N≥5) with variance reporting. No cherry-picked demos. Open benchmark data →

Cross-domain

Validated across 5 distinct discourse categories — brand crises, cross-cultural fandom, viral misinformation, grief events, and activist movements. Not a single-domain trick.

Test the reaction before the announcement.

Whether it's a rebrand, a product launch, or a CEO statement — know what happens before it does.
