ACC Intelligence Launches Definity Synthetic Audience Platform for Marketing Pre-Testing

ACC Intelligence has launched Definity, a synthetic audience platform designed to help brands pre-test creative campaigns and messaging, announced in a press release. The company describes the platform as a “flight simulator” for marketing decisions, enabling teams to simulate audience responses in seconds and forecast campaign outcomes.

Definity generates high-fidelity digital twins of customers, investors, employees, regulators, and media using census data, behavioral patterns, ethnographic research, and proprietary online behavior signals. The system includes pre-built cohorts for Gen Alpha, Gen Z, and Millennials, with options for custom modeling across different stakeholder groups.

The platform’s synthetic audience technology was validated through a study conducted with USC Annenberg, comparing simulated responses with those of 509 real Gen Alpha participants. The study achieved a 96% alignment rate, confirming the accuracy of Definity’s predictive models. According to ACC Intelligence, the platform is already being used by Fortune 500 companies to test creative concepts and reduce decision-making risks.

Definity includes built-in privacy protections, accuracy validations, and bias reviews. It aims to give marketing teams decision clarity, cultural foresight, and creative security when developing and testing campaigns.
