Making the shift to a new CMS can seem daunting, but Sanofi’s digital transformation story proves that, with the right partner and platform, it’s possible to achieve remarkable results. Partnering with Crescendo Collective and leveraging the power of Magnolia, Sanofi migrated 500 websites, trained over 500 business users, and achieved a 20% faster digital delivery. Here's how this healthcare giant turned its complex web ecosystem into a streamlined, scalable, and efficient digital powerhouse.


Unlock success with these key strategies


Sanofi, a global leader in healthcare with a presence in 100 countries, faced enormous digital complexity. With over 100,000 team members and numerous country-specific websites, the organization struggled with operational inefficiencies, a fragmented tech stack, and inconsistent branding. Managing their web presence, spread across six legacy platforms, became an increasingly costly and resource-intensive task. It was clear that a bold digital strategy was needed to unify their processes, improve scalability, and enhance their ability to deliver targeted, impactful content to audiences worldwide.



The solution

Sanofi teamed up with Crescendo Collective and chose Magnolia as its Digital Experience Platform (DXP), a decision that delivered both immediate and long-term benefits.


  • Efficient migration

    Crescendo orchestrated the seamless migration of 500 websites, with 300 completed in under two years. Using Magnolia's robust hybrid headless model, Crescendo reached unprecedented speeds—migrating 70 websites and over 7,000 pages in just two months. This minimized costs and paved the way for a unified web presence.

  • Empowering business users

    Content creation and management were simplified with Magnolia’s user-friendly interface. Sanofi implemented a comprehensive training program, empowering over 500 business users and 80 agency partners to manage the platform with confidence. Beginners and experts alike could create content with ease while maintaining strict brand and compliance standards.

  • Streamlined content creation and delivery

    Leveraging Magnolia’s headless capabilities, Sanofi implemented a central content factory and embraced a modular approach to content production. This enabled rapid localization, more efficient collaboration between teams, and the personalization of Healthcare Professional (HCP) portals using data-driven insights. By integrating tools like Algolia for advanced search and Veeva Vault for medical content, the organization transformed its digital strategy.



The impact


The results of this migration were transformational:


  • 20% Faster digital delivery

    Sanofi's teams now create and deploy digital content more efficiently, thanks to Magnolia’s intuitive interface and streamlined workflows.


  • Significant cost savings

    Sanofi realized ongoing yearly savings of $255,000, with projections hitting $1.1 million over five years—including migration costs. By reducing licensing and support fees, the company redirected resources toward innovation.


  • Improved user engagement

    Post-migration, conversions increased by 92% within 60 days, and organic traffic saw a 4X year-over-year growth after optimization. The combination of better user experience and enhanced SEO capabilities paid off.


  • Error-free authoring

    The implementation of templated content creation reduced errors and accelerated time-to-market, allowing global teams to operate with agility while maintaining consistency.


A next-generation solution

Magnolia not only met but exceeded Sanofi’s expectations. “Magnolia enables hundreds of non-technical users across our business to self-serve and create digital experiences for their audiences—while ensuring brand consistency and allowing us to govern the tech stack,” stated Anna Majewska, Director of Digital Commerce at Sanofi. She added, “It has helped us streamline and accelerate our digital delivery by over 20%.”

With Magnolia’s flexible yet powerful platform, Sanofi achieved a unified digital experience, consolidation of legacy systems, and an improved content lifecycle. Their next big milestone? Integrating further AI-powered tools to localize and optimize content so teams can serve audiences faster and better.
