Case Study: D'Addario achieves 10x online sales growth with Optimizely One

D'Addario increases online sales by 10x using Optimizely One

D’Addario, the global musical accessories manufacturer, needed a modern platform to scale both B2B and direct-to-consumer sales across international markets. Its legacy homegrown e-commerce system lacked multilingual, multi-currency, and self-service capabilities, making it difficult to support global transactions and personalized customer experiences. D’Addario chose Optimizely One to unify its commerce and content operations and better serve retailers, distributors, and consumers.

Using Optimizely, D’Addario launched a more scalable digital commerce setup with CMS, commerce, experimentation, and data capabilities, enabling faster site updates, personalized experiences, and improved self-service. The results were significant: 10x growth in total online sales from 2019 to 2024, 500,000+ loyalty members integrated across channels, and successful expansion into European markets and B2B self-service sales.
