Synthetic Personas: AI-Powered Audience Simulation & Campaign Testing

Synthetic personas are one of our newest managed services, designed to transform how creative teams test and validate ideas.

Business Context

Marketing teams are under pressure to produce more content in less time while navigating fragmented audiences and rising expectations. Traditional research is slow and expensive, and teams often lack fast, reliable ways to test ideas early in the process.

The Challenge

Across the brands and agencies we work with, a common pain point emerged: insights were spread across multiple systems. Teams struggled to integrate CRM data, surveys, e-commerce activity, social signals, and behavioural analytics into a clear understanding of their customers. Testing often happened too late to influence creative direction.

What they needed was a way to understand audience reactions before committing time and budget to production, a way to simulate audience response in real time using the data they already have.

Our Process

We work with companies to build a pipeline that creates synthetic personas from a wide range of data sources. We pull together anonymised real-world data, integrating surveys, CRM records, behavioural analytics, and e-commerce activity. We then layer in social media language, reviews, and community conversations to capture emotion, tone, and nuance.

This multi-layered approach produces synthetic audience segments that feel real, behave realistically, and respond with the depth of human customers.

The Solution

Synthetic personas allow teams to upload copy or creative and receive instant, segment-level feedback. They can ask questions such as “How would this audience respond to X?”, explore ideas, and compare responses across audience groups - all within minutes.

The Impact and Why It Matters

Teams reduce creative risk and accelerate validation, shifting from slow, manual research to rapid, continuous insight. This leads to more confident decisions and stronger, more effective campaigns.

Synthetic personas give organisations a new way to understand and anticipate audience behaviour. They transform scattered data into an always-on testing environment that improves creative quality and speeds up decision-making.

This technology represents a fundamental shift in how teams engage with their audiences. For brands, agencies, and product teams, synthetic personas:

  • replace slow research with rapid, on-demand insight

  • give creatives and strategists a safe environment to experiment

  • unlock defensible, scalable IP for long-term competitive advantage
