For Infra leaders

Stop being the translator between prod and finance

You own the infrastructure. Somehow you also own every cost question. Costory gives your engineering teams, and their AI assistants, the cost context that used to live in your head.

Why did our Kubernetes cost spike 40% last week?

Answered with Costory

+€8.4k

+41% on EKS · traffic flat

Cost jumped Thursday but Datadog request volume barely moved. Root cause: node autoscaler kept new pods after traffic dropped. That's waste, not growth.

Want an alert next time cost per request drifts more than 20%?

Set alert on cost per request

Thinking

The pattern

Cost questions always route to you

What lands in your DMs

"Why did AWS jump 14% in March?"

"What did the Payments team actually spend last quarter?"

"Is this Datadog bill normal?"

What it takes to answer

Cost Explorer, Datadog billing, the spreadsheet someone built six months ago

Mapping line items to teams by hand, one provider at a time

An hour of your time. Every time.

You're the only person who can untangle it. So the ticket always routes to you.

What Costory does

Costory removes the context work, not the ownership

Allocation runs on tags you already maintain

80% of teams, products, and environments map automatically from provider metadata and native tags. You review the edge cases once. New services inherit the logic.

The "why" is already attached

Deploys, pricing changes, and traffic spikes are correlated with cost movements at ingest. When finance asks about EC2 in March, the answer is one query, with the deploy link attached.

Team leads stop asking you

Weekly Slack digests and drift alerts, per team, in channel. Every squad lead sees their own costs. Cost visibility stops being one person's job.

Same context layer for your agents

Engineers query from Claude Code or Cursor. Deploy, scaling, and on-call agents pull the same allocated spend through the same endpoint.

Setup

Start using Costory in 30 minutes with Terraform

One terraform apply to connect every provider. Allocation runs on the tags you already maintain.

Use cases

Use cases built for your role

EKS cost visibility

Surface idle nodes and over-provisioned pods before finance does.

Kubernetes waste

Surface idle nodes and over-provisioned pods before finance does.

dbt + BigQuery visibility

Track and allocate costs at the dbt model level.

Auto-allocate by environment

Prod, staging, and dev split automatically, no manual tagging.

Shared Cloud SQL allocation

Split cost across consuming teams, based on actual storage or compute usage.

Decentralize FinOps

Push ownership to squads. Every team lead sees their own costs, weekly.

Outcomes

What you get with Costory

Finance pings route to Slack, not your DMs

Monthly cost review takes 15 minutes, not a half-day

Engineers and agents query the same allocation model

You go back to roadmap work

Pay for the context layer, not the dashboards

€250 / month flat — up to €10M annual spend

No percentage of cloud spend

No enterprise sales call

No need to hire a FinOps team

Frequently Asked
Questions

How secure is my data, and what exactly do you access?

Read-only on a single billing dataset per provider (AWS CUR, GCP BigQuery export, Azure SAS, Datadog usage, LLM usage). No application data, no PII, no production access. Costory runs on Google Cloud with encryption in transit and at rest, authentication via SSO (OAuth, or SAML on the Plus tier).

Full security and subprocessor list:

€250 / month, is that real?

My tags are inconsistent, do I need to clean them up first?

How fresh is the data, and can I use Costory for real-time alerts?

What if you don't natively support one of my data sources?
