Trusted by teams to turn cloud waste into growth budget
On average 20–40% of cloud spend is waste, and it's not your team's fault
Cloud waste isn't usually one bad decision. It's four structural problems that compound month after month, while your engineers are heads-down on the roadmap.
Blind spots
You see the total bill, not which team or service is driving it. Without cost allocation, no one owns the waste, and what no one owns, no one fixes.
Missing expertise
Even your most senior engineers can't spot overspend in an environment they've worked in for years. There's no lessons from other environments or costs to compare.
No Priority
Engineering deadlines always win against cost optimisation. Without quantified savings reaching leadership, cost work stays on the backlog while the bill climbs.
Unaware teams
Teams build without estimating cost upfront. By the time the bill arrives, the surprise isn't just the number. Sometimes the entire architecture isn't commercially viable, and rework is the only option.
AI-first FinOps. Engineering-deep savings.
The four-step system that finds your cloud waste, fixes it with your team, and keeps it from coming back.
1. Koritsu Experts Audit
We start with a baseline audit run by FinOps experts who have saved over £4M across 15+ cloud environments. You see every finding, costed and prioritised, before any work begins. If we don't deliver savings, you don't pay.
2. 1st FinOps Analyst AI Agent
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.
3. Pair with your engineers
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.
4. Continuity through the platform
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.
How we get you started
One baseline audit is all it takes to help each Koritsu customer start saving 20-40%, so we start every engagement with this 3 step framework.
1. We listen
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.
2. We audit
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.
3. We act
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.
Up and running fast, your security stays intact
- We're up and running in days, not weeks: a 1-hour scoping workshop, streamlined onboarding, and fast time to value
- We start with read-only access to billing exports and CloudWatch metrics with no code access, no production access, no IAM expansion required
- When deeper access is needed, it's scoped to a specific finding, explicit allowlist and reviewed by your security team before anything is granted
“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.”

Why teams love Koritsu
Your engineers ship faster, with cost as a first-class signal
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 — a chatty inner loop, a missing cache, a misconfigured replica — get reviewed alongside your infra changes, so the next deploy is the cheaper one.
Most clients see this as the alternative to hiring a £80k+ FinOps analyst internally.
