What rex by AureliaX is

rex by AureliaX is a marketing mix modelling platform for measuring and planning performance across online and offline channels. It uses Bayesian machine-learning models and response curves to support budget allocation, forecasting, scenario planning, and ROI reporting. The modelling process tests starting assumptions against 2–3 years of historical data. Users can inspect model components, confidence intervals, starting assumptions, and how the data changed them.

The platform connects to 500+ marketing services, including Google Ads, Meta, TikTok, Snapchat, LinkedIn, and Pinterest. For offline channels without APIs, templates accept weekly or monthly spend and reach data. Recommendations are updated monthly and reviewed by rex’s team; onboarding typically involves 2–3 sessions and a monthly review. rex is available on the web and through an API. Its maker says it does not rely on user-level cookies and describes it as GDPR-compliant and privacy-first. Pricing is tailored to business needs, users, and modules, with pilot offers for strategic partners.
