FinOps agent for cloud, AI and data spend
Your FinOps, on call 24/7.
Without hiring for it.
Costory is a FinOps agent. It monitors your cloud, AI and data spend, optimizes it and explains every change, in Slack and in Claude.
30-day free trial. Connect in under 30 minutes, get your first optimization recommendation the next day.
How it works
Three steps.
No FinOps hire in the loop.
01
Connect in under 30 minutes
Read-only access to your billing exports and metrics, with Terraform or CloudFormation, or paste one prompt in Claude. Costory has no write access to your cloud.
02
Get a first recommendation the next day
The agent allocates your spend to teams, watches it against each team’s baseline and sends the first optimization recommendation, with usage evidence and an impact estimate.
03
Work where your team already works
Alerts and investigation threads land in Slack. Ask from Claude, Cursor or Grok Bot. Your team approves every change.
What Costory does
One agent. Three jobs.
Around the clock.
Costory’s agent monitors, optimizes and explains your cloud, AI and data spend, 24/7, in Slack and in your assistant. Read-only on your cloud: your teams make every change.
01
Monitor
Every bill, every day, against each team’s baseline. When spend moves, the owner gets a thread in Slack with the cause: the deploy, the team, the service.
Checkout · Amazon RDS

Cache hit rate dropped sharply, owner notified
Data platform · BigQuery

02
Optimize
Rightsizing, idle resources, commitments and model routing, with usage evidence and an impact estimate. Your team decides what ships.

Explain
Ask in Claude, Cursor or Slack: why did AWS go up last week? You get allocated numbers you can check down to the invoice line.
Why is our infrastructure cost per customer up 9% this quarter?

Finding cost change factors
Two drivers, both owned and already investigated.
1. New EU region for Checkout: about €14,000 a month since July (Platform team).
2. Support: the switch to a larger LLM in August doubled the cost per ticket; the team is testing a cheaper model for simple tickets.

FAQ
Frequently asked questions
What does Costory’s agent do?
It watches allocated cloud, AI and data spend, investigates changes, recommends optimizations and follows them up in Slack. You work with it from the assistant you already use, such as Claude, Claude Code, Cursor or Grok Bot. Your team approves what goes live.
Do we need a FinOps person to run it?
No. The agent does the daily monitoring, investigation and recommendation work, and an engineer reviews what it proposes. Teams that already have FinOps roles use it too.
How fast do we get started?
Connection takes under 30 minutes. The first optimization recommendation arrives the next day.
Does it change anything in our cloud?
No. Costory has read-only access to billing exports and the metrics you connect. Rightsizing, commitments and other changes are decided and made by your team.
How is it priced?
Flat monthly plans, billed annually: Copilot, €250/month (up to €10M annual cloud spend) and Copilot Pro, €1,000/month (up to €20M). Both include a 30-day free trial.
