Overview
RadixArk is an infrastructure-first, deep-tech company building large-scale inference and training systems for the entire AI community. Our mission is simple and ambitious: make frontier-level AI infrastructure open and accessible to everyone. Today, the most advanced training and inference stacks live inside a few companies. They employ exceptional infrastructure engineers, but their systems primarily serve internal needs. Every new AI lab rebuilds the same schedulers, compilers, serving engines, and training pipelines from scratch. Infrastructure engineers are often treated as a support function--asked to optimize for immediate model metrics rather than long-term system design and first principles. The result is a lot of unintended waste: duplicated effort, underused insights, and slower progress for the broader ecosystem.
