Client overview
Milliman is a global leader in actuarial consulting, benefits administration, and risk management technology. With $1B in annual revenue and offices in major cities worldwide, Milliman delivers strategic guidance and software to help insurers, employers, and governments manage health and financial risk.
The challenge
Milliman’s digital ecosystem was fragmented, outdated, and difficult to scale. Operating on legacy Sitecore 9 (MVC) infrastructure, their global teams struggled to efficiently manage 40+ regional and product sites, deliver content across 10+ languages, and showcase their industry-defining research and consulting expertise.
The shift
This wasn’t just a replatform—it was a global digital reinvention. Milliman:
- Migrated 40+ websites across 10+ languages to Sitecore XM Cloud
- Adopted a multi-tenant architecture for global scale and governance
- Centralized digital marketing, SEO, and content operations
- Implemented a component-based design system to amplify brand consistency
- Integrated enterprise search to unlock discoverability of high-value content
