Clustree

Clustree was a French HR-technology startup founded in 2014 that built an AI-powered skills engine and a multilingual skills ontology (over 53,000 verified skills consolidated from more than one billion job skills) used to match employees to internal roles and mobility opportunities. It was acquired by Cornerstone OnDemand in early 2020 (approximately $18.5M, all-cash) and its technology was folded into Cornerstone's People Intelligence / Skills platform. The independent Clustree brand is discontinued: clustree.com no longer serves a website and there is no live developer portal, public API, documentation, SDK, or package registry presence under the Clustree name. This profile is retained as a network identity/lead record only.

Clustree is profiled on the APIs.io network. Tagged areas include Company, Software-as-a-Service, HR Tech, Talent Management, and Skills.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
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/clustree: open an issue to ask a question, or submit a pull request to add artifacts.
