CAST AI scores B on the Alion truth index (A is best, E worst), measured over 7 open roles re-checked against its own hiring board: 0% look like ghost listings, 71% have gone stale and 0% are the same role posted again. Its roles close in a median of 49 days. It measures how much of what this employer publishes turns into a real, finite search - not the employer as a workplace. How the index is computed
Overview
CAST AI is a cloud automation company founded in 2019 that cuts Kubernetes cost and operational load without asking teams to change their applications. Its platform continuously analyses running workloads and rebalances them onto the cheapest suitable instance types, spot capacity and node sizes across Amazon Web Services, Google Cloud and Microsoft Azure, typically halving compute spend. Headquartered in Miami, Florida with engineering in Lithuania, it has expanded from cost optimisation into Kubernetes security posture, application performance automation and routing for large language model traffic.

Products
AI Enabler
AI Enabler routes large language model requests to the cheapest capable provider and caches repeated calls. It gives engineering teams cost control over inference spend the same way the platform does for compute.
cast.ai
Kubernetes Security
The security module checks clusters against configuration benchmarks, image vulnerabilities and runtime policy. Findings are ranked by exploitability so teams fix what actually matters.
cast.ai
Autoscaler
The autoscaler provisions and removes nodes based on actual pod demand, choosing the cheapest compatible machine type each time. It handles spot interruption and fallback without manual node pool configuration.
cast.ai
Cost Monitoring
Cost monitoring breaks cloud spend down by cluster, namespace, workload and team with live projections. It gives platform teams and finance a shared view of where Kubernetes money goes.
cast.ai
Automated Optimization
The optimisation engine rightsizes and rebalances Kubernetes clusters in real time across instance families and spot capacity. It applies changes automatically rather than producing a report for engineers to act on.
