Athenian

Athenian was a full-cycle software-development analytics platform founded in 2019 by Eiso Kant, with a seed round led by Point Nine. It integrated GitHub, JIRA, and CI/CD tooling to give engineering leaders end-to-end visibility into their delivery pipeline — lead time, cycle time, deployment frequency, PR review dynamics, and goal alignment — deliberately measuring teams and events rather than ranking individuals. The company has since wound down: athenian.com and athenian.co now redirect to github.com/athenianco and the production API host api.athenian.co no longer resolves. However, the OpenAPI specification (athenianco/api-spec, 79 operations, 218 schemas) and the open-source API implementation (athenian-api-open, MIT) remain publicly published on GitHub, which is why this profile is enriched from the real, still-available API contract.

Athenian publishes 15 APIs on the APIs.io network, including align API, events API, filter API, and 12 more. Tagged areas include Company, Engineering Intelligence, Software Development Analytics, Developer Productivity, and DevOps.

Athenian’s developer surface includes authentication and 12 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/athenian: open an issue to ask a question, or submit a pull request to add artifacts.
