Costory is a FinOps platform that gathers billing and usage data from AWS, Google Cloud, Azure, Datadog, OpenAI and Anthropic into one context. It allocates costs and links cost changes to deployments and metrics. It is delivered as hosted SaaS, with MCP connections for assistants such as Claude, Cursor and VS Code, Slack digests, BI tools and a REST API. According to the vendor, it reads billing and usage exports rather than application code.
Costory SAS is a French company, and the vendor's information page lists its headquarters in Paris. The vendor states EU data residency and encryption of all data in transit and at rest. The main point to examine is therefore the sub-processors and the connections to non-EU cloud and AI platforms from which the product reads data. The privacy policy contains no explicit reference to GDPR or a data processing agreement, so a European organisation should check that agreement and the sub-processor list before use.
