Clastix provides a Kubernetes infrastructure platform called kMetal that enables enterprise platform teams to run multi-tenant clusters on their own bare metal, on-premises, or sovereign infrastructure. The platform moves control planes to shared infrastructure, reducing control plane machines by up to 97% and provisioning new tenant clusters in approximately 20 seconds. Clastix also develops the open-source projects Kamaji for hosted control planes and Capsule for multi-tenancy.

Problem
Organizations running Kubernetes at scale face mounting complexity as environments, teams, and workloads grow. Creating separate clusters for each team, customer, or environment drives infrastructure sprawl, operational overhead, and rising costs—with platform engineers spending more time managing infrastructure than enabling the business.
Solution
Clastix provides kMetal, a standardized, production-ready platform for running Kubernetes infrastructure at enterprise scale. kMetal eliminates the "control plane tax" by running all tenant cluster control planes as pods on a shared management cluster, and removes the need for hypervisor licensing by using kernel-native KVM for compute isolation and OVN for networking. The platform enables self-service provisioning of production-ready tenant clusters in roughly 20 seconds within administrator-defined guardrails, while unifying fleet management, upgrades, and policy enforcement under a single control point. Clastix also maintains the open-source projects Kamaji (hosted control planes) and Capsule (multi-tenancy) that underpin the platform.
Target Audience
Primary customers are cloud and platform teams at enterprises running Kubernetes at scale, including organizations in telecommunications, AI and HPC infrastructure, public sector and defense, and cloud and managed service providers.
