Run your cloud at peak efficiency.
CarnotCloud allocates every cloud dollar to the team that owns it, catches cost spikes in hours, and hands engineers ranked savings they can ship in a click. Customers cut cloud costs 20–40% — with read-only access and no agents.

The problem
Cloud spend grows faster than anyone can explain it.
Bills arrive weeks late, tags are inconsistent, and the engineers who could fix waste never see what it costs. Industry surveys put wasted cloud spend at roughly 27–32%. For a $10M cloud bill, that’s up to $3M a year doing no useful work.
Nobody owns the bill
30–40% of spend typically sits in shared, untagged or unallocated buckets. Without ownership, accountability stops at the invoice.
Surprises show up at month-end
A misconfigured autoscaler or runaway AI job can burn six figures over a weekend — long before anyone opens a dashboard.
Savings die in the backlog
Recommendations live in spreadsheets, disconnected from the engineers and workflows that would actually ship them.
The Carnot principle
Every engine has an efficiency limit. So does your cloud.
In 1824, physicist Sadi Carnot proved there is a theoretical maximum to how efficiently any engine can turn energy into useful work. We built CarnotCloud on the same idea: measure how close every team, service and workload runs to its efficiency limit — then close the gap, cycle after cycle.
- 01See. Bill-accurate visibility across every cloud, cluster and AI provider.
- 02Own. 100% of spend allocated to the people who can act on it.
- 03Optimize. Ranked, owner-routed savings across usage and rates.
- 04Govern. Budgets, policies and AI that keep efficiency the default.
One platform
Everything FinOps needs. Nothing it doesn’t.
Replace a patchwork of native consoles, spreadsheets and point tools with one platform that every team — FinOps, engineering, finance and leadership — actually uses.
Bill-accurate visibility. 100% allocation.
Unify AWS, Azure, Google Cloud, Kubernetes, AI and SaaS costs in one ledger that reconciles to your invoices — then assign every dollar to a team, product or customer with virtual tags and shared-cost rules.
- Virtual tagging & shared-cost splitting
- Showback & chargeback statements
- Unit economics: cost per customer, order or feature
Virtual tagging rules
IF account ∈ prod-payments-* OR tag:service ~ "pay*" → BU = PaymentsSPLIT shared EKS + support fees BY cpu-hours → all BUsSavings, ranked and routed to the right engineer.
300+ checks surface waste across five layers — from orphaned volumes to architectural inefficiency — while commitment intelligence models your optimal Savings Plan and RI coverage.
- Rightsizing, idle and modernization opportunities
- Commitment scenarios scored by savings and risk
- Jira, Slack, PR and AI-coding-agent hand-offs
Catch spikes in hours — with the root cause attached.
Seasonality-aware machine learning watches every account, service, cluster and AI model, and alerts the owning team the moment spend leaves its expected range.
- Hourly detection with dollar-impact ranking
- Automatic root cause and owner routing
- Slack, Teams, PagerDuty and email
- Actual cost
- Expected range (ML baseline)

Forecasts, budgets and guardrails that run themselves.
Driver-based forecasts finance can plan on, budgets for every owner, tagging policies and cost estimates in every pull request — so efficiency becomes the default, not a quarterly project.

Where the next dollar of waste is hiding
Kubernetes, AI and data platforms are now the fastest-growing lines on the cloud bill. CarnotCloud sees inside all three.
Kubernetes, down to the pod
Bill-accurate allocation by cluster, namespace, workload and label — with idle cost exposed and request rightsizing engineers trust.
- checkout $41.2K
- search $28.7K
- ml-inference $22.3K
- platform $14.1K
- Idle & unallocated $19.8K

Carnot AI: ask your cloud bill anything
A FinOps analyst for every team. Plain-English answers grounded in your data — and an MCP server that brings cost context to Claude, ChatGPT, Cursor and your own agents.
Why did our AWS bill jump last week, and who owns it?
Spend rose $48.2K (+11.4%) week over week. Three drivers explain 92% of it:
- EC2 in prod-us-east-1 +$27.1K — ASG
checkout-apimin capacity raised in deploy #8812. Owner: Payments Platform. - NAT Gateway data transfer +$12.6K — new cross-AZ traffic from
search-indexer. - Bedrock +$4.7K — doc-summarizer moved to a larger model on Tuesday.

100% of spend allocated in 14 days
“We went from 61% of our AWS bill allocated to 100% in two weeks. For the first time, every GM sees their own cloud P&L — and acts on it without being chased.”
$186K spike stopped in 3 hours
“CarnotCloud flagged a runaway data pipeline at 7 a.m. on a Saturday, with the root cause and the owner already attached. That single alert paid for the platform for the year.”
34% lower compute cost in one quarter
“Our engineers actually use it. Each saving lands in Jira with the exact change, the risk and the dollar impact, so it gets shipped instead of debated.”
18% → 33% effective savings rate
“The commitment modeling gave finance the confidence to act. We moved from 41% to 82% coverage with zero stranded commitments — and we understood every dollar of the decision.”
38% lower Kubernetes spend
“Pod-level allocation ended the “whose cluster is this?” debate. Following the request-rightsizing recommendations took 38% off our EKS bill without a single incident.”
