Its platform publishes curated analysis organized by country and by sector, and clients receive it by email. ### Analyst writes in Word One person can edit at a time ### Formatting bridge A third-party tool that broke bullets and links ### Four systems Crossed before a note could go live ### Note goes live Read almost entirely in the inbox Media handled by hand Note structure in a markup only the legacy system could read New templates and features had stopped being an option *The challenge* ## A portal that worked, but couldn’t grow. The legacy portal still worked, but it couldn’t support Eurasia Group’s growth. Several features no longer fit how the firm worked, and almost all client engagement happened in email rather than on the platform. **Eurasia Group had three goals: modernize the web platform, launch a mobile app with full feature parity, and build an experience good enough that clients would choose the portal over their inbox.** *The goal* ## Modernize the portal, add a mobile channel and migrate nearly 20 years of research Project manager Project manager Developer Developer Developer Designer DevOps engineer Claude + Claude Code *The team* ## A lean, AI-native delivery team Cheesecake Labs delivered the project with a dedicated team of seven, working in two-week sprints with weekly demos for Eurasia Group’s stakeholders. Engineers worked in Claude Code with a shared set of skills, some built in-house by Cheesecake Labs, so every feature was built and delivered the same way. That is how a team of seven delivered the web platform, the mobile app and the full migration. ### Planned the work Wrote user stories, broke epics into tasks and proposed technical approaches ### Built the features Every developer used Claude Code to implement their part of the platform ### Ran QA The team carried out the full testing phase with Claude Code ### Reviewed the code Claude reviewed changes before engineers approved them ### Engineers make the final call An engineer approves the changes before they ship *How we built it* ## Claude across the whole delivery lifecycle Every member of the team worked with Claude or Claude Code, with shared Claude Code skills standardizing how work moved from story to release. Claude works at every stage. Engineers make the final call. **3–4 months** Cheesecake Labs projects, historically **3 weeks** Eurasia Group, with Claude Code *Speed* ## A mobile app in three weeks, not three to four months Claude mapped every existing web component to its mobile equivalent, giving the team a complete blueprint for the React Native app. The result was a mobile app with full feature parity with the web platform in three weeks. ### The analyst adds their data As a table, CSV or description, inside the Claude desktop app with the prompt already filled in. ### Claude returns a chart definition Ready to paste back into the editor. ### The portal validates it And recolors anything that falls outside the palette. ### It renders everywhere As an interactive chart on the web and as an image in emails and PDFs. *AI in the product* ## Charts built with Claude, on the portal’s own rules The prompt is generated from the portal’s own rules, so what comes back is already on-brand and ready to publish. The prompt also works with other assistants, and the chart field accepts Flourish embeds. ### Discovery The team mapped every existing process, flagged critical dependencies such as email delivery, and documented the legacy data model to plan the migration of all historical content. ### Parallel operation Once all content was on the new platform, both systems ran side by side and clients moved over in waves. Every article was published on both, so no client missed an update. ### Cutover After the last clients moved, the legacy system stayed live for two more weeks as a safety net. It has since been shut down. ### 12 native editor extensions ### One entry feeds web, email, PDF and mobile ### Schema under version control *The migration* ## A three-phase migration with no gap in coverage ### AI-assisted planning Claude writes user stories, breaks down epics and drafts technical approaches Delivery ### Claude Code for every developer Features built with Claude Code across web, mobile and migration work Delivery ### AI-run QA The full testing phase carried out with Claude Code Delivery ### AI code review Claude reviews changes before an engineer approves them Delivery ### Web-to-mobile mapping Claude mapped each web component to its mobile equivalent for the React Native app Delivery ### AI in the product “Open in Claude” turns an analyst’s data into a validated, on-brand interactive chart Product *At a glance* ## Where AI shows up in the project **3 weeks** Mobile app **37,966** Documents migrated **1.86M** Research emails **2,155** Active users **137** May 2026 pilot **2,155** August 2026 ### A mobile app with full parity in three weeks Claude’s component mapping cut the mobile build from the usual three to four months to three weeks. ### Nearly 20 years of research, migrated without a gap Every article was published to both systems during the transition, and the legacy platform is now retired. ### One publish, three live channels The same entries feed web, email and PDF. ### Analysts publish richer content With charts and audio, without a developer in the loop. *Results* ## A lean team, a full platform, no lost coverage Delivered by a team of seven, with Claude as part of the workflow at every stage. *Here’s what Eurasia Group has to say about working with us.* [MISSING] Testimonial pending client approval.
