Know what resonates before pressing send. Limbik brings human-validated synthetic audiences directly into Braze — understand how your content will resonate with target audiences in under 30 seconds with survey-grade accuracy. Evaluate creative concepts, optimize campaign messaging, and test A/B creative across 7,000+ audience segments in 60+ countries.

Unlike generative AI, which creates content, Limbik’s human-validated synthetic audiences simulate human belief, emotion, and behavior to evaluate whether messaging will resonate with specific audiences and whether it will spread. Our platform blends continuous surveys from millions of real people with proprietary AI to deliver human-validated synthetic audiences—digital populations that capture, with research-grade accuracy, how people think and act.

With these audiences, Limbik has developed two proprietary models: Resonance (predicts the percentage likely to believe or agree with a message) and Spread (predicts how many will engage with or share it). These insights replace guesswork with actionable clarity—instantly revealing which messages will connect, in seconds rather than weeks.

Before you launch your next campaign, message, or creative—see how your audience will actually respond. Limbik's human-validated AI audiences let you pressure-test and optimize in minutes and hours, not days or weeks.

With Limbik, instantly understand:

• Headlines: Which subject line increases open rates?
• Messaging: Does “affordable luxury” or “premium value” resonate more
• Creative: Which image drives stronger emotional response?
• CTA’s: “Learn more”vs. “Get started” – which one converts?

Limbik integrates as a pre-deployment intelligence and validation layer within the Braze workflow.

Typical flow:
1. Brand generates campaign copy using internal teams or AI tools.
2. Messaging is tested within Limbik (Cortex) against selected audience segments.
3. Resonance and Spread scores and audience feedback are returned.
4. Messaging is optimized based on feedback.
5. Finalized content is deployed through Braze.

Evaluating resonance should match the speed at which you can now create assets using AI. With Limbik's human-validated synthetic audiences integrated into Braze, it does.

Every message your team produces can be evaluated against the audiences that matter—before a campaign launches, before a narrative takes hold, before you find out the hard way that what resonated with you didn't resonate with them.
