Pay only if you save
At the end of the month you pay 20% of what you saved, via your AWS bill. No savings, no charge. Without the lock-in of AWS Savings Plans, you can leave anytime.
You pay only a fraction of what you save, directly from AWS
At the end of each month, we charge 20% of the savings we generate in your AWS account. If we generate no savings, we don't charge you.
Example: if you saved $1,000, at month's end you pay $200. If you saved $0, you pay nothing.
The charge comes directly through your AWS bill — no separate invoices, no extra payment methods.

Zero changes to your infrastructure
Frust works entirely at the billing layer. We need read-only Cost Explorer access — no sub-org migration, no agent installation, no IAM role changes to your workloads.
Reduce AWS spend without the lock-in risk
We buy the reserved capacity on our accounts. You pay Frust a monthly fee — a fraction of what we save — with no multi-year commitment to AWS.
Extend runway on your biggest infrastructure cost
AWS is typically the #1 or #2 infrastructure line item. Frust turns that into an immediate, recurring saving — $0 upfront, cancel anytime.
Always in your control — no access to infrastructure or data
Billing-level read permissions only
You deploy a read-only CloudFormation stack: Frust sees your usage and billing, never your data or your resources.
No infrastructure changes
Frust never creates, modifies, or deletes any resource in your AWS account. It only reads.
No sub-org migration
Your account doesn't move to another organization; the invite only manages the savings commitments.
Remove the permissions anytime
You delete Frust's stacks whenever you want and revoke all access. No lock-in, no multi-year contracts.

FAQ
Everything you need to know before getting started
How much can I save on AWS with Frust?
Frust reduces your AWS bill by up to 30% through Flexible Reserved Instances and Savings Plans. The exact figure depends on which AWS services you run, since Savings Plans cover a broad range of compute and database services. See exactly how much you're leaving on the table: see your savings number in about 10 minutes, or book a demo to review your specific case.
How does Frust work?
Through read-only access, Frust adds an account to your AWS Organization that continuously monitors and analyzes your Cost Explorer and Cost & Usage Report (CUR). Based on how your AWS accounts consume, it dynamically and automatically adds or removes Reserved Instances and Savings Plans to maximize your organization's overall savings. If there are savings, Frust charges 20% of what's saved through your own AWS bill — if not, you pay nothing, billed just like you already pay AWS.
What does Frust cost?
Frust charges a 20% success fee on the savings it generates, billed through your own AWS bill — no upfront cost and no minimum commitment. If Frust doesn't save you money, you pay nothing.
Is Frust safe? What access does it need?
Frust uses read-only AWS IAM permissions scoped to billing, Cost Explorer, and Cost & Usage Report (CUR) metadata only. It never accesses your workloads, application or database data, source code, or business data, and the CloudFormation stack can be deleted from your AWS console at any time.
Is this legitimate? Could using Frust get me in trouble with AWS?
It's fully legitimate: Frust runs on AWS's own discount programs, using the same technology AWS provides to optimize Reserved Instances and Savings Plans. If Frust did anything AWS didn't allow, it could never have become an AWS partner or be listed on AWS Marketplace, since AWS rigorously reviews every company before approving it.
Do I need to change my AWS infrastructure?
No. Frust operates entirely at the billing layer. There are no changes to your infrastructure, no sub-organization migration, and no agent installation required.
Am I locked in? What happens if my AWS usage changes?
No lock-in. Frust takes on the commitment and the risk toward AWS for the Reserved Instances and Savings Plans — not you. So whether your usage drops, you decide to leave Frust, or you even move off AWS entirely, that exposure is Frust's, not yours, and you can remove access and leave at any time.
How long does it take to get started?
Within 48 hours you get a concrete savings estimate for your account, and getting started takes under 10 minutes: see your savings number by deploying Frust's read-only stack in your AWS Organization. If you then decide to go ahead — with no commitment — you install a second Frust stack, and in 24 hours or less you start capturing the savings Frust generates through Reserved Instances and Savings Plans.
Is there a FinOps alternative to Vantage, CloudZero or ProsperOps in Latam?
Yes — and not only in Latam. Unlike visibility-only tools, Frust actively reduces your costs by purchasing AWS commitments on your behalf, success-based, with no upfront cost or lock-in. Setup takes under 10 minutes with no infrastructure changes on your side. And because Frust is an add-on on AWS's global Marketplace, it's available worldwide — on every continent — billed directly through your own AWS account.
Should I estimate my savings myself, or book a demo?
Both are free, and every month you wait is savings left unclaimed. If you'd like to see the numbers for your account, see your savings number in about 10 minutes — no call required. If you'd rather walk through how Frust works and ask questions first, book a demo and we'll do it live.
