Our vision
[02]Your companion to building the next generation of successful games

Our Pillars
[03]We are masters of our craft, because we care about what we do. We create opportunities for the experts we hire to showcase their capability and potential.
Communication and collaboration with our clients is incredibly important to us. This is how we maintain strong relationships and build trust and safety in everything we do.
We're nimble, responsive, and solution-focused. When circumstances change, we pivot fast. When needs evolve, we're already there to help you.
[OUR_LEADERSHIP]
[04]Our leadership comes from backgrounds like Amazon, Tencent, Google, Xbox, with many being former colleagues at UK games tech unicorn Improbable that served tens of millions of MAU across their systems.
Services
We offer services specialized around the technical elements of multiplayer games as well as in-engine work.
Online services
"From off-the-shelf Games-Backend-as-a-Service solutions to fully bespoke builds, we design, develop, and integrate the online services your game depends on.
We have extensive experience building and integrating solutions for unified accounts for cross-platform player progression, matchmaking, inventory systems, integration for data analysis and telemetry in a way scales alongside the playerbase.
Our approach is to not work with just a limited set of technologies, but rather select technologies that make sense for a given game title."
Technologies
Multiplayer
"We specialise in Unreal Engine networking but also understand key networking fundamentals like client prediction and entity interpolation, enabling us to work with custom network stacks for custom engines or make modifications to the Unreal Engine source code when this is required.
With our extensive experience working on MMOs, we don't shy away from tackling the larger challenges that come with large playerbases and the optimizations required to have a performant multiplayer experience."

Gameplay
We embed with your teams to build and refine gameplay systems and tools, including 3Cs, GAS, AI, PCG, UI,and performance optimisation for live-service games.
With our extensive experience within Unreal Engine as well as familiarity with custom game engines we are able to develop the systems required to build games that players enjoy. From bots to fill lobbies to systems to procedural generation of landscapes and from adding controller support to PC-titles to polishing the 3Cs for a better player experience.
By understanding the underlying technologies of Unreal Engine, we are able to make great performance improvements for players as well as the workflows for designers to make it possible to run live-service games and continue development at the same time without running into roadblocks.
Technologies
Cloud
We handle cloud and bare‑metal infrastructure end to end, from cloud architecture and hybrid setups to build automation, dev tooling, CI/CD, and game server fleets.
Without the right structure, running live-service games becomes very expensive. For setting up game infrastructure, we always keep cost optimization in mind. We do this by making the right decisions between bare-metal, cloud architecture or most often, a hybrid setup with bare-metal as a base with auto-scaling cloud infrastructure to handle peak traffic.
With our DevOps specialists, we set up CI/CD pipelines with full submit-to-deploy build automation, automated testing, infrastructure-as-code and game fleet deployment with the goal of as little discrepancies between development and production as possible. We want to ensure that successful local testing means the game will run without issues when deployed.
As part of our infrastructure work, we are also able to take care of internal infrastructure to be used during development, like the configuration of version control with nodes in each region for distributed teams, automation tools for local development and implement security best-pracices like VPNs, role-based access control to environments and secure internal networking.

Collaboration Model
Companion Group fully merges our delivery teams into your studio, making them a natural part of the project and iteration process. Our staff operate in one of two models: "Augmentation" - Where our staff act as an extension of your core teams focused on execution at your direction. Or "Feature Delivery" - Subject matter specialists create cross-disciplinary pods in order to deliver entire game systems, modes or features where technical leadership and direction is provided alongside high quality execution.
Pricing is provided on a Time & Materials basis, with all resources offered at a single blended rate per discipline. Discounts are available based on scope and duration of work, with larger commitments seeing a commensurate reduction in cost.
