  35%

  reduced EC2 spend on spot capacity alone — Karpenter consolidation, ARM64 Graviton node pools and automated spot-instance execution — with no Reserved Instances or Savings Plans purchased, so the saving carries no multi-year commitment and scales the platform horizontally without adding headcount

• Stanza Systems

  25%

  reduced main-account EC2 operating costs using Karpenter-based autoscaling and cluster ingress optimization, to absorb variable demand without over-provisioning

• Nutrien Agriculture Solutions

  75%

  shortened the production release interval from every two months to every two weeks, using GitHub Actions reusable workflows, custom TypeScript actions and platform self-service patterns, with ArgoCD and Argo Rollouts making off-cycle hotfixes routine

• Nutrien Agriculture Solutions

  40%

  reduced LATAM cloud operating cost (approximately), using FinOps rightsizing, automated resource lifecycle management and decommissioning
