How Acme SaaS Cut AWS Spend 34% Without Touching Code

“We had 15% budget overruns every quarter. Our VP Eng thought we were optimized. We were scared of a ‘midnight bill’ from a bad deployment.” — CTO, Acme SaaS

The Problem

Acme SaaS, an 80-employee B2B platform, was burning $52K/mo on AWS with 15% quarterly overruns. Engineering suspected waste but lacked time to audit. Finance wanted predictability. The CTO feared a runaway bill from a misconfigured autoscaling group.

“We tried AWS Cost Explorer and a FinOps tool, but all we got were charts. No one told us *what to turn off*.” — VP Engineering, Acme SaaS

The 7-Day Nimbus Audit with Gemma-4

What We Did

  • Day 1-2 Connect: Read-only IAM access. Zero engineering time.
  • Day 3-4 Analyze: Gemma-4, our proprietary AI, parsed 6 months of usage for waste patterns across EC2, RDS, S3, NAT Gateways, and data transfer.
  • Day 5 Recommend: Delivered Terraform-ready fixes + plain-English playbook. Prioritized by $ impact vs effort.
  • Day 6-7 Protect: Enabled Circuit Breakers to alert on drift and auto-create PRs for new waste.

Why Gemma-4 Is Different

Unlike CloudZero or nOps that resurface AWS recommendations, Gemma-4 is trained on 500+ mid-market audits. It finds:

  • Orphaned cross-account resources
  • Bad autoscaling + zombie containers
  • Cross-AZ data transfer waste
  • GP2 volumes that should be GP3

And it writes the fix — not “consider rightsizing”.

Results + GreenOps Impact

“We cut $18K/mo and reduced carbon by 4.2 MTCO2e/month. That went straight into our SEC climate disclosure. The ROI was 11 days.” — CFO, Acme SaaS

Acme implemented 80% of recommendations in 2 weeks. Circuit Breakers now block new waste before it hits the bill. They moved from quarterly budget surprises to ±3% variance.
