Numinexus connects to your AWS account via a read-only IAM role, analyses cost and utilisation data across every service, and delivers prioritised actions to eliminate waste — highest-impact changes first.
Read-only access • Takes ~60 seconds • No credit card
Numinexus connects using AWS STS AssumeRole.
We never see or store your AWS access keys.
Account monthly spend: $12,400
Recommendation #1
Downsize EC2 instance i-0a3b
Current instance type: m5.xlarge
Suggested instance type: t3.medium
Average CPU utilisation: 2.1%
Average memory utilisation: 18%
Estimated saving: $312/month
Confidence: High
Reasoning:
Instance has been consistently underutilised for the past
21 days with no observed memory pressure.This is one recommendation from a typical report. See a full example report →
30% of cloud spend is waste. For teams spending $2K–$50K per month on AWS, that means thousands of dollars silently draining every month. No FinOps team to catch it. No time to dig through Cost Explorer graphs. No system that connects cost data to infrastructure decisions.
AWS Cost Explorer, CloudHealth, Vantage — they all answer where is the money going? None of them answer: what exactly should I change, and in what order?
Copy IAM policy from Numinexus
Create a read-only role in your AWS account
Paste the role ARN
Run the infrastructure analysis
No agents • No credentials stored • Access can be revoked anytime
Provide an IAM role ARN with read-only access. No agents, no keys, no credentials stored. You control the trust policy and can revoke access instantly.
Numinexus pulls cost data from Cost Explorer, utilisation metrics from CloudWatch, and resource inventory from AWS Config. An AI reasoning layer correlates patterns across services to surface inefficiencies that rule-based tools miss.
Receive a ranked list of specific changes — the exact resource to modify, the estimated monthly saving, the reasoning behind it, and a confidence level so you know what's safe to act on immediately.
CloudHealth costs $2,000+/month and serves enterprises. AWS Trusted Advisor requires a Business support plan and runs generic rule-based checks. Teams spending $2K–$50K/month on AWS — the fastest-growing segment — have no tool that actually understands their infrastructure.
Average savings detected: 17% of monthly spend
Numinexus builds a unified view of your infrastructure — correlating spend data, utilisation metrics, and resource inventory across 50+ AWS services. The analysis engine detects patterns a rule-based system cannot: an instance costing $400/month at 2% CPU, an RDS database with zero connections for three weeks, NAT gateway traffic that should be routed through a VPC endpoint.
Today, Numinexus identifies specific ways to reduce your AWS bill. But the underlying system — infrastructure analysis, pattern detection, cross-service correlation — is designed to do more than cut costs.
Next, Numinexus will surface architecture insights: misconfigurations, performance bottlenecks, and reliability risks that aren't visible in any single AWS console. The goal is a system that continuously understands your infrastructure and helps you improve it — not just a one-time audit, but an ongoing engineering partner.
"Why should I give you access to my AWS account?" is the right question. The answer is built into how Numinexus works.
We use AWS STS AssumeRole — the industry standard for cross-account access. You create the role, you control the trust policy, you can revoke access in seconds.
Our IAM policy requests only ce:GetCostAndUsage, cloudwatch:GetMetricData, and config:ListResources. No write access. No modifications. Ever.
We never see, handle, or store your AWS access keys. Temporary session tokens are used for each analysis and expire automatically.
The exact IAM policy JSON is published and auditable. You know precisely what permissions you're granting before you grant them.
Seven years building production systems with Python and AWS. Fintech background at Harmoney — credit risk and lending platforms where infrastructure costs directly hit unit economics. I built Numinexus because I spent too many hours manually hunting for AWS waste that a system should have found for me.
One-time analysis for accounts up to $5K/month spend. See your top recommendation and decide if the full report is worth it.
Monthly infrastructure analysis. Full prioritised recommendations. Unlimited spend. Alerts when new optimisations are detected.
Multiple AWS accounts. Shared reports across your team. Priority analysis and dedicated support.
If your team spends $2K+ per month on AWS and you want to know exactly what to change — not just where the money goes — we'd like to work with you.
