A note from the founding team

Why we built Costory

We built Costory because, honestly, we were tired.


Tired of being the Designated FinOps that one SRE or infra lead pulled into every cost fire. "Why did the bill spike?" "Who's burning all the GPUs?" "Is this S3 bucket… normal?"


And every time, the same problem: billing logs know nothing. The real answers live in Slack threads, tribal knowledge, and whatever's in your head.


Your options were terrible: either build an internal tool you'll never have time to maintain, or pay a FinOps vendor priced for enterprises.


So we built Costory to share the load.


It filters the noise, spots what matters, and gives you investigation leads instead of raw alerts. It connects billing with GitHub PRs, Datadog usage, and your actual stack context then uses AI to explain anomalies clearly (even to the CFO).


It's the FinOps assistant infra teams have always needed and priced like something you can actually justify.
