Synthetic Research Explained, Understanding AI-Powered Audience Testing for Marketers

What is synthetic research and how accurate is it really?

In this episode of That’s What I Call Marketing, Conor Byrne sits down with Dr. Ben Warner, former Chief Data Adviser to the UK Prime Minister and co-founder of Electric Twin, to unpack one of the most talked-about developments in modern market research: synthetic audiences.

This is not ChatGPT pretending to be a consumer. Synthetic research uses real-world survey data, behavioural modelling and large language models to create AI-driven audience simulations that allow organisations to test messaging, product ideas and strategy at speed before committing real budgets. If you work in marketing, insight, product, strategy or leadership, this episode will challenge how you think about research, risk and decision-making.

In this episode, we cover:

• How AI allows teams to iterate research questions instantly
• The difference between testing ideas safely and making bold decisions blindly
• Why trust and validation matter in emerging AI tools
• Where synthetic research complements (not replaces) conventional methods

Why this matters

• Every organisation says it wants to be “customer-centric”.
• But insight is often expensive, delayed, siloed or underused.
• Synthetic research introduces a new tool into the decision-making toolkit — one that allows teams to explore, iterate and pressure-test ideas before they go live.
• Whether you are a CMO defending budget, a product lead developing a proposition, or a strategy team modelling future scenarios, this conversation explores how AI-driven research could reshape how decisions are made.
