## CORTUA

- [CORTUA — AI-Powered Amazon Advertising System](https://www.adference.com/cortua): CORTUA is an autonomous advertising system that unifies strategy and execution in a closed loop. It starts with the product, not the campaign: the system analyzes each product's lifecycle, competition, keywords, seasonality, and market potential, then selects from a catalog of proven strategic directives developed with senior strategists at leading global Amazon agencies (including Front Row). After user approval, CORTUA builds campaign structures, assigns keywords, sets bids, and continuously monitors and optimizes performance. Every recommendation comes with an explanation before going live — Glass Box, not black box. AI is used where it excels (classification, context analysis, competitive assessment); where predictability matters (bids, budgets, campaign structures), deterministic algorithms built on over a decade of research handle the execution. CORTUA is not a chatbot, not an autonomous agent, and not a prompt wrapper — it is professional business software with bounded AI. Currently in early access with a 14-day free trial.
