Most FinOps stops at reservations and rightsizing. We trace inefficiencies back to the code and architecture causing them. Typically a 20–40% optimisation opportunity in the first audit.
5.0 ★★★★★ £4M+ realised savings across 15+ cloud environments, verified against billing 
It's four structural patterns that compound month after month, while your engineers are heads-down on the roadmap.
You see the total bill, not which team or service is driving it. Without cost allocation, no one owns the inefficiency, and what no one owns, no one fixes.
Senior engineers know their environment deeply, but cost patterns only become visible when you've seen dozens of environments side by side. Without that comparison, the outliers look normal.
Engineering deadlines typically win against cost optimisation. Without quantified savings reaching leadership, cost work stays on the backlog while the bill climbs.
When teams design new services, the cost implications don't show up until the bill lands weeks later. By then the architecture is in place, and sometimes the shape itself stops being commercially viable.
The four-step system that surfaces inefficiencies, fixes them with your team, and keeps them out.

Run by engineers and FinOps experts with £4M+ in realised savings across 15+ cloud environments. Every finding costed and prioritised before any work begins. Billed only on realised savings, verified against your bill.
Kori runs also during the audit and keeps watching after, spotting anomalies and patterns the human eye misses. Built specifically for cloud cost work, not a generic chatbot pointed at your bill.
Quick wins ship in the first session. Code-level and architectural changes ship alongside your team. Most of our peers hand you a report. We hand you the savings on next month's bill.
Once savings are live, the platform takes over. Cost allocation by team, service, and feature. Continuous monitoring so the waste stays gone, and so the next architecture decision your team makes is a cost-aware one.
One baseline audit is typically enough to surface 20–40% in realised savings for each Koritsu customer, so we start every engagement with this 3 step framework.
1-hour intro call
We walk your decision makers, IT, infra, and engineering leads through the solution and make sure it's the right fit before anything starts.
1-hour strategy & onboarding call
We align on where to focus, get context from your team, and set up platform access so we can start the audit without back-and-forth.
3 day expert audit
Using our unique mix of consultant expertise, SaaS platform and AI agents, we analyse every resource for rightsizing, idle capacity, redundancy, and commitment modelling then go deeper into your codebase to surface architectural inefficiencies.
1 hour report presentation
We present all findings as specific, costed actions with current cost, estimated saving, tax-adjusted saving, effort ratings and priority for clarity on phased implementation.
1 hour quick win session
Working directly with your infra admins and developers, we apply the fastest, lowest-effort savings. This typically unlocks around 20% of your total identified savings in a single session.
Deeper architectural wins
Code-level engineering changes where savings require deeper architectural or code-level work will need to be actioned by your team, timelines vary depending on the scope of changes involved.
"Working with Koritsu has reduced my platform costs by about 60%, and the performance improvements have been outstanding. My platform runs noticeably faster, and their service has delivered great value."

60% in this environment; 20–40% is the typical range across our engagements.
Kori shows your engineers exactly which services, regions, and accounts are draining budget, without leaving their normal workflow. Idle nodes, oversized clusters, and runaway batch jobs all surface in plain language.
Architectural inefficiencies that standard FinOps tools can't see get reviewed alongside your infra changes: a chatty inner loop, a missing cache, a misconfigured replica. The next deploy is the cheaper one.
A single view of every account and environment. Scoped read-only role, no broad policies, no production access required. The audit covers the standard ground (rightsizing, idle capacity, redundancy, commitment gaps), then goes one layer down into resource-level CUR data to surface the architectural patterns driving the bill. Findings surface the pattern. Your architects keep the call. Workload context lives with your team, and the recommendation respects that.
When deeper changes are needed, we ship them alongside your engineers. Your team reviews and merges. We don't deploy. Each finding comes with the architectural rationale, the verification approach against your bill, and the rollback path. Savings hold without your SLOs moving.
Costs are broken down to team, service, and customer level so you can answer 'how much does this customer cost us?' in seconds, not weeks. Anomalies get caught before they hit next month's invoice.
When you're underwriting a new product or a price change, you have a defensible cost-per-unit baseline — not a spreadsheet of best guesses pulled together the night before.
