USE CASE #1
Boosting AOV with Real-Time Product Recommendations
The challenge
While users were actively browsing product detail pages—a key sign of strong purchase intent—Sans Complexe saw a missed opportunity to further increase conversion rates and basket size. Without timely, relevant product recommendations, engaged shoppers were not being guided toward additional products they might love, limiting both engagement and average order value.
The solution
Insider leveraged advanced analytics to track browsing behavior, including time spent on page, scroll depth, and interaction patterns. By detecting when users were most engaged, Insider delivered personalized product recommendations at the optimal moment—ensuring shoppers received suggestions when they were most likely to interact and convert.
The results
30.5%
increase in AOV
USE CASE #2
Optimizing Purchase Funnel with
AI-Driven Promotions
The challenge
Sans Complexe identified a valuable opportunity to make promotional content more dynamic, especially in high-visibility areas of their website. By personalizing these touchpoints, they aimed to engage every shopper more effectively and guide them down the purchase funnel according to each individual’s unique preferences and behaviors.
The solution
With Insider, the brand personalized not only product recommendations but also promotional banners in real time. As users interacted with the website, their profiles—including preferences and engagement data—were continuously enriched in the CDP, enabling dynamic, relevant promotions to be served at every step of their journey.

USE CASE #3
Reactivating Inactive Customers with Precision Targeting
The challenge
A significant number of users abandoned their journeys mid-funnel, becoming inactive. Sans Complexe recognized an opportunity to recover this high-potential segment, which could reclaim lost revenue and increase overall ROAS per user by re-engaging them effectively.
The solution
Insider deployed predictive models — Next Best Channel, and High Likelihood To Engage — to identify the optimal channel and timing for reactivation. By analyzing past engagement patterns and reachability scores, Sans Complexe delivered hyper-personalized messages precisely when users were most likely to respond, minimizing wasted outreach.
USE CASE #4
Seamless Replatforming with Insider’s Shopify Connector
The challenge
Sans Complexe was replatforming its backend from Magento to Shopify and needed to ensure customer experiences and engagement remained seamless throughout the migration. With a large volume of user, product, and engagement data being transferred, the team anticipated a significant development burden and risked disruptions to the customer journey during this complex backend integration.
The solution
By leveraging Insider’s native Shopify Connector, Sans Complexe achieved seamless synchronization of user data, product catalog, and engagement events between platforms—without any heavy development load. This ensured that customer experiences and personalized engagement continued uninterrupted, even as the backend migration was underway.
