AI Personalization Engine Drives 35% Revenue Growth

Real-time recommendation system increases engagement by 2.5x and CTR from 1.2% to 4.1%

The Challenge

RetailStream, a fast-growing e-commerce platform with 2M monthly active users, was struggling with low engagement and conversion rates. Their generic product recommendation system showed the same products to all users, resulting in a meager 1.2% click-through rate and stagnant revenue growth. Customer lifetime value was declining as users found competitors offered more personalized shopping experiences.
