# Athenian

> Athenian was a full-cycle software-development analytics platform (founded 2019, CEO Eiso Kant; seed led by Point Nine). It integrated GitHub, JIRA, and CI/CD to give engineering leaders end-to-end delivery metrics focused on teams and events rather than individuals. The company has since wound down — athenian.com and athenian.co now redirect to github.com/athenianco and api.athenian.co no longer resolves — but the OpenAPI specification and open-source code remain published on GitHub (athenian-api-open, MIT).
