Rebellions

What Rebellions does

Rebellions is a chip and software company focused on AI inference infrastructure—building purpose-engineered neural processing units (NPUs) and the associated software stack and rack/server systems to run large-scale AI workloads efficiently in data centers. The company’s platform messaging centers on deploying and operating inference workloads (including LLMs and multi-modal models) with an open developer experience and an integrated, cloud-native serving stack designed to scale from single-node to rack-scale deployments. Rebellions also positions itself around “sovereign AI” and telecom/region-specific deployments, partnering with ecosystem players such as SK Telecom, Arm, and Red Hat for enterprise and sovereign infrastructure paths.
