Global modernization on XM Cloud, simplified.

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Milliman’s digital ecosystem was fragmented, outdated, and difficult to scale.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

Tech stack used

  • Sitecore XM Cloud – Modern SaaS CMS with visual authoring
  • Next.js – High-performance frontend framework
  • Storybook – Centralized design system for component reuse
  • Cloudflare – Performance, security, and global CDN delivery
  • Coveo – AI-powered enterprise search and content discovery
  • Netlify – Global deployment for multi-site, multi-region delivery
  • Sitecore Personalize & CDP – Personalization and behavioral data activation

(What we did)

Built for scale. Engineered for leadership. We helped Milliman evolve into a unified, cloud-native enterprise—streamlining 40+ sites into one powerful platform that delivers thought leadership globally, adapts locally, and accelerates performance across every region, language, and service line.

Global platform migration

Milliman, a $1B actuarial and consulting powerhouse, partnered with Fishtank to future-proof their global digital presence. We migrated over 40 sites and 10+ languages from Sitecore MVC to XM Cloud—streamlining operations and amplifying their leadership position in risk, healthcare, and financial services.
