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
About a third above its usual daily spend, investigating
Support · OpenAI
Cache hit rate dropped sharply, owner notified
Data platform · BigQuery
Within baseline
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.
24/7

what would partitioning save on that model?

At last week’s run frequency, scanned bytes would drop from 4.1 TB to about 0.3 TB per run, roughly €580/week.
Claude + Costory
You’re right to run FinOps with Claude.
Costory makes it work.
Keep Claude as the way your teams ask. Costory does the data work and adds an agent that watches 24/7, alerts the owner, explains the cause and acts in your workflow.
01
Ingested and normalized data.
Billing exports from AWS, Google Cloud, Azure, Kubernetes, data platforms and LLM APIs, in one cost model with the same definitions for every team.
02
Costs allocated to teams.
Virtual Dimensions map spend to teams, services and features, even with incomplete tagging, and keep up with reorganizations.
03
An agent watching 24/7.
It alerts the owner when spend moves, explains the cause with deploys and usage metrics, and acts in Slack and in your assistant.
04
Numbers you can verify.
Every figure the agent gives traces back to the raw data in the Costory interface, down to the invoice line.
