Klépierre, a European shopping mall operator, embarked on a massive overhaul of their web presence to address the challenges of the digital revolution and transformative shifts in the shopping experience. They decided to undertake a global platform redesign with Proximity, a creative and technology agency, to develop 98 sites within six months. However, they encountered performance and price barriers with their planned Sitecore redesign. To overcome this, Proximity rearchitected on the Jamstack model, leveraging a headless Sitecore CMS and Netlify as the distributed edge network, which massively reduced cloud spend while delivering performant sites on schedule. This decoupled approach enabled cost savings, improved workflows, simpler cloud management, great website performance, and faster content delivery, ultimately empowering Klépierre to deliver fast experiences across Europe with a user-friendly and author-friendly experience.
