AWS FinOps & Cost Optimisation

Krobonic helps businesses reduce AWS spend through cost audits, optimisation projects, and ongoing FinOps governance.

For companies spending roughly GBP 10k-GBP 50k a month on AWS without a dedicated FinOps function. I find where the budget is going, fix what's wasted, and put the guardrails in place so it stays fixed.

Services

Three engagements, one goal: spend matches what you actually need.

Each one stands alone, but they're designed to flow into each other - audit finds the savings, the implementation project realises them, and the retainer keeps them from drifting back.

01

AWS Cost Audit

Goal - identify savings opportunities across your AWS estate.

Who this is for

Companies spending GBP 10k-GBP 50k/month on AWS without a dedicated FinOps function.

If cloud costs are becoming a line item that keeps growing and nobody owns it, that's the gap Krobonic fills.

SaaS companies

  • 10-200 employees
  • AWS-based product
  • No dedicated FinOps team

Scale-ups

  • Recent funding round
  • Growing engineering team
  • Cloud spend increasing quickly

SMEs

  • AWS spend becoming noticeable
  • CTO wearing multiple hats
  • No formal cost management process

Common characteristics

  • AWS spend growing quickly
  • No formal cost management process
  • Limited visibility of where cloud costs come from
How it works

Start with the audit. Each stage produces something concrete you can act on.

No long contracts. The audit stands alone, and continuing into an implementation project or retainer is always your call.

Stage 01

Cost Audit

Read-only access to your billing console and Cost Explorer. Every service reviewed, spend mapped by driver, and a prioritised list of what to fix first - delivered as an executive summary with supporting detail.

Stage 02

Implementation Project

Changes are made directly in your AWS environment - rightsizing, reserved capacity, lifecycle policies, tagging - with full documentation and a before/after savings comparison. Priced on gain share: you pay a percentage of what's actually saved.

Stage 03

FinOps Retainer

Monthly cost governance - spend monitoring, anomaly detection, Savings Plans management, and a written report. Positioned as ongoing AWS Cost Governance, not generic support. From GBP 500-GBP 2,000/month depending on spend and complexity.

Built by an engineer who's been on the other side of the bill.

Krobonic is run by Callum, a backend and DevOps engineer who has spent years building and tuning production systems on AWS in budget conscious environments, including the unglamorous work of figuring out why the bill went up.

That background means recommendations are written the way an engineer would want to receive them: specific, reversible, and explained in terms of what changes and why - not just a number on a slide.

Let your developers focus on building great products, not on the bill.

Get started

Start with a free cost audit - no obligation to go further.

The audit requires read-only access to your AWS billing console. You'll receive a full breakdown of current spend, key cost drivers, and a prioritised list of savings opportunities - whether you engage Krobonic to implement them or not.
