Challenge

A fast-growing SaaS had an AWS bill compounding at 14% month over month with no tagging strategy, no reserved instances, and no cost accountability. Engineering shipped fast; nobody owned the cloud bill.

What we did

  • Implemented landing-zone governance and tagging policies
  • Built a reserved-instance and savings-plan strategy
  • Enforced tagging compliance via Service Control Policies (SCPs)
  • Delivered monthly FinOps reporting broken out by feature team

Outcome

  • AWS spend reduced 38% without a capacity cut
  • Tagging compliance enforced at over 96% via SCPs
  • A clear cost-per-customer metric now feeds pricing decisions
  • The FinOps practice is now owned internally, we advise quarterly
