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.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Epsor the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Epsor scores 14.9/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Epsor
Each block below is one kind of artifact we hold for Epsor. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
