**Company:** Animation Digital Network

Animation Digital Network (ADN) is one of Europe's largest anime streaming platforms, with around 400,000 subscribers and 58% watching on mobile devices. ADN began as a French-language anime streaming service, expanded into Germany in 2023 and Poland in spring 2026, and has a fourth country launching soon, with several more planned. CTO William Yim runs an engineering org of 22 developers split into multiple teams — web, apps (mobile, TV and gaming consoles), backend, back office, and payments — all using Sentry. For a streaming service delivered via browser, iOS, Android, smart TVs, and gaming consoles across a growing list of countries, a slow-loading screen can be the difference between a subscriber watching an episode or unsubscribing. ADN uses Sentry's User Feedback widget so the QA team can field user input and use the connected session replay, traces, and breadcrumbs to understand what happened before passing to the team responsible for a fix — cutting time to resolve a production issue from two to four hours down to 15 minutes to an hour. Each team builds and owns its own Sentry dashboards covering iOS, Android, web, and internal tools, filtering by app version, region, platform, and environment and monitoring metrics like time to initial display, cold/warm app starts, and frozen frame delays. Sentry's trace waterfall helped ADN uncover a geolocation request taking around five seconds to respond, which the backend team optimized down to the millisecond range. On release day, Release Health and crash-free rate are the first things the team checks on any new version, watching a build through staging and pre-production before it reaches subscribers.
