GOOGLE CASE STUDY

Continuous consumer intelligence across 3 countries 86% accuracy

A brand decision still waits weeks for a single survey, at high cost and with a short shelf life. To address Google's challenges of cost, time, scale, complexity, and diversification, Galaxies ran a synthetic persona pilot across three Latin American countries, combining three layers of real data: quantitative research with 1,200 real people per country, proprietary behavioral blocks (Big Five and economic games), and observed on-device behavior, all under ISO 27001, LGPD, and GDPR. The model produced 14 personas (5 in Brazil, 5 in Argentina, and 4 in Mexico), which structure and recommend full-funnel narratives for Shorts and long-form video, and deliver actionable, recurring insights to Google's MMS teams, turning the initial investment into a permanent decision-making asset.
