rex by AureliaX

rex by AureliaX is a Marketing Mix Modelling platform for measuring and optimizing performance across online and offline marketing channels. It uses Bayesian machine-learning models, response curves and scenario planning to help teams consider budget allocations. The modelling process tests starting assumptions against 2–3 years of historical data. Users can inspect model components, confidence intervals, assumptions and how data changed them. The maker says recommendations are updated monthly and reviewed by its team. rex connects to 500+ marketing platforms, including Google Ads, Meta, TikTok, Snapchat, LinkedIn and Pinterest. For offline channels without APIs, it provides templates for entering weekly or monthly spend and reach data. Its listed capabilities include budget planning, forecasting, scenario planning and ROI reporting. Onboarding typically includes 2–3 sessions followed by a monthly review. The platform is available through web and API. Its maker describes it as GDPR-compliant and privacy-first, and says it does not rely on user-level cookies. Pricing is tailored to business needs, users and modules; pilot programs are offered to strategic partners.

rex combines marketing mix modelling with budget scenarios and visibility into model assumptions. Organizations should consider its historical-data requirement and request tailored pricing to assess fit.

rex is designed for mid-market and enterprise companies, including marketing, finance and leadership teams. Its historical-data requirement makes it relevant to teams with 2–3 years of data for modelling.
