Cast AI
Kubernetes and GPU cost automation FinOps platform for rightsizing, spot management, bin-packing, and autonomous cluster optimization. Cast AI took a strategic investment in January 2026 at a valuation above $1 billion.
Platform, SRE, and FinOps teams running meaningful Kubernetes estates that will allow automated rightsizing and node optimization.
Teams without Kubernetes, or buyers who only want commitment-management savings without touching cluster automation.
Verdict
Cast AI fits Kubernetes-heavy shops that want automated cost optimization rather than another spend dashboard. Public packaging includes free monitoring plus Growth and Enterprise dimensions; AWS Marketplace lists Growth from about $1,000 per month and Enterprise from about $5,000 per month with managed-CPU usage charges. Customers report material cluster savings when they trust the automation; permissions and control concerns are the diligence items.
