Live-service game studio specialist for AAA multiplayer and engine architecture

Computer Games London, England 51–200 employees Founded 2022 Privately Held

Companion Group partners with major studios to build and scale live-service games, focusing on multiplayer architecture, networking, and backend systems. The tech stack spans Unreal (C++) and Unity (C#) with deep AWS/Azure infrastructure, PostgreSQL, Redis, and Kubernetes — a shape that reflects their core competency: backend-heavy multiplayer enablement rather than game content creation. Active hiring is concentrated in senior engineering (5 roles) with sparse design slots (2), signaling a resource-constrained model where contractors or partner studios handle art while Companion focuses on systems engineering.
