What Taggstar does

Taggstar Technologies Ltd. is a UK-based AI-powered conversion messaging platform founded in 2013 and headquartered in London. The company specializes in real-time social proof messaging for enterprise eCommerce, delivering behavioral notifications (e.g., 'Selling fast! 50 bought in the last hour'), product attribute messaging, and dynamic product badging to large retailers and brands. Taggstar's platform comprises four core products: the Social Proof Enterprise Plan (20+ customizable message types with full-funnel coverage and AI optimization), the Social Proof Pro Plan (entry-level tier for specialty retailers), Attribute Messaging (Gen AI-extracted product attribute surfacing), and Dynamic Badging (rule-based automated product badges). Underpinning the suite is an AI neural network optimizer that selects the best message in real time, plus the 2025-launched AI Merchandiser that uses Gen AI to extract product attributes from catalogs.
