What is it?
NEXUS: Galaxies Lab is a Synthetic Personas platform that enables brands to stop simply analyzing the past and start simulating future behaviors.
Developed with Galaxies—a pioneering company in persona creation and part of the HSR ecosystem—using predictive AI, real-world data, and methodological governance, it reliably represents consumer behavior, allowing ideas, campaigns, and products to be tested before they go to market.
AI-generated behavioral representations based on real-world data.
Allows us to anticipate reactions, test hypotheses, and reduce risks.
Works as a strategic simulation lab.
Data-driven decision making, not guesswork, with the timing that marketing requires.
TRANSFORMATION
How does it work?
Synthetic Personas allow for continuous conversation, testing, and validation of strategies, without relying on recruitment, fieldwork, or external timing.
In a single environment, it is possible to explore qualitative reactions, run quantitative tests at scale, and validate stimuli with speed and depth.
Direct conversations with personas for qualitative exploration.
Conducting mass quantitative research with automated reporting.
Testing stimuli (campaigns, packaging, products) quickly and cost-effectively.
Validating ideas before investing in media or production.
Drastic reduction in time, cost, and risk in the decision-making cycle.
Always-on intelligence for marketing, product, and growth.
Predictive AI with statistical validation and data governance.
Synthetic Personas are built from a rigorous process that combines real-world data, unsupervised machine learning, generative AI, and statistical validation.
Our personas are statistically validated and audited by a control group, achieving 89% assertiveness.
Structured process for ingesting, analyzing, and clustering data.
Using machine learning algorithms to create behavioral profiles.
Integrating generative AI with NLP and prompt engineering.
Testing rounds with control group and assertiveness rate between 80% and 90%.
Total data governance, with LGPD/GDPR compliance.
Privacy guaranteed: simulation without exposure to real consumers.
