Online Services Summit 2026 returns to Stockholm on 4 November 2026, bringing together senior online‑services engineers, backend specialists, tech leads, and studio leadership from across Europe. This fifth edition focuses on the toughest challenges in running online games at scale—from identity systems and matchmaking to player data, telemetry, live operations, and launch‑day infrastructure. With fireside chats, a keynote, panels, and intimate roundtables, the summit is designed for deep technical exchange rather than sales pitches or expo‑floor noise. 

Hosted at Avalanche Studios Group HQ, the event is invite‑only and free for approved guests, offering a full day of expert sessions, networking, and sponsored dinners the evening before. Previous editions have included teams from Ubisoft, Epic, Riot, Respawn, Activision, Netflix, Unity, Arrowhead, Mediatonic, and more—making it one of the most concentrated gatherings of online‑services expertise in the industry. Attendees can expect candid discussions, practical insights, and the chance to compare notes with peers solving the same high‑scale engineering problems.
