Epsor

Epsor is a French fintech, founded in 2017, that manages employee savings and retirement plans (épargne salariale et retraite) for companies and helps them turn that benefit into an HR lever. A certified B Corp and mission-driven company, Epsor ranks among the top 10 employee-savings and retirement providers in France and serves more than 2,500 corporate clients. It targets HR, Compensation & Benefits, and Finance teams at mid-size and large French firms, combining a pedagogical, personalized saver experience, an open-architecture fund range (40+ funds from 15+ asset managers, with a strong ESG/SRI focus), and year-round support to run and promote the plan. Epsor is neither an asset manager nor a bank: it is the single point of contact for companies and their employees, and delegates account-keeping to Société Générale Securities Services (SGSS). Products span PEE, PER Collectif (PERECO), PER Obligatoire, intéressement, participation, abondement, and employee share ownership. Epsor exposes no public developer API; this profile captures its public identity and security posture for the API Evangelist network.

Epsor is profiled on the APIs.io network. Tagged areas include Company, Financial-Services, Fintech, Employee Savings, and Retirement.

Epsor’s developer surface includes engineering blog, support, and 7 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/epsor: open an issue to ask a question, or submit a pull request to add artifacts.
