Cocoon

Cocoon is next-generation employee leave management software that automates the complexities of compliance, claims, and payroll for every type of employee leave (parental, medical, caregiver, accommodation, bereavement, and personal) across all 50 U.S. states. It factors in state, federal, company, and insurance benefits to calculate eligibility, generate designation notices, and streamline the leave experience for both employees and HR teams. Cocoon connects to 20+ HRIS and payroll platforms (Workday, Rippling, Gusto, BambooHR, ADP, Paylocity, UKG, and more) via API integrations that sync employee data in real time. Founded in 2020 by former Stripe and Square leaders and backed by Index Ventures and First Round Capital, Cocoon was acquired by TriNet in April 2026. Cocoon is a consumer of HRIS/payroll APIs rather than a publisher of a public developer API; no public OpenAPI, SDKs, or developer portal are published.

Cocoon is profiled on the APIs.io network. Tagged areas include Company, Human Resources, Leave Management, HR Tech, and Compliance.

Cocoon’s developer surface includes engineering blog, pricing, changelog, and 6 more developer resources.

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/cocoon: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
