STARTING POINT
A historically grown system landscape at its limit.
Groundies was running two platforms in parallel: OXID for the US market and Shopware for the international setup. The split created high manual effort, rising costs, and blocked innovation - especially with the US market entry.
-High manual effort in operations and support
-Rising costs from complex technical dependencies
-Very long time-to-market for new features
-No A/B testing or structured conversion optimization
-Limited transparency in data and analytics
-Internationalization not scalable on the old setup
OBJECTIVES
Build the technical foundation for international growth.
Performance
Implement a fast, scalable Shopify Plus setup
Automation
Significantly reduce manual work through targeted integrations
Iteration
