About
We build the cost context layer
for engineering teams and their AI assistants
Cloud and AI bills keep growing more complex. Engineers need to know what their work costs, and why it changed, without becoming FinOps specialists. Costory gives them, and the assistants they work with, that context.
Why Costory
Dashboards got cheap. Context didn’t.
Every provider ships a cost dashboard, and AI assistants can now read raw billing data. What is still missing is context: which team owns a cost, which deploy changed it, and what it means per customer. Costory allocates every bill to the way your company works and makes that context available in Slack, in the web app and through the FinOps MCP.
