Seiza
Seiza was a French social-recruitment advertising and recruitment-automation SaaS platform dedicated to frontline hiring — hospitality and restaurants, transport and logistics, agri-food, industry, retail, temp staffing, healthcare and construction. Founded in Paris in 2010 as Work4 Labs by Stephane Le Viet, Gautier Machelon and Matt Brown, it built its early business on sourcing candidates through non-professional social networks rather than job boards or LinkedIn, later rebranding from Work4 to Seiza. It raised roughly $22.8M in venture capital (Serena, among others) and served about 400 clients across Europe and the US, including McDonald's, Sysco, Ecolab and Veolia. The product was a recruiter web application — social sourcing campaigns, profile enrichment, one-click calling, a compatibility index, automated interview scheduling, SMS/messaging and reporting — plus a fixed catalog of 23 named ATS connectors (Bullhorn, Workday, Greenhouse, SmartRecruiters, iCIMS, Cornerstone, Recruitee, Talensoft, DigitalRecruiters, Beetween, Fountain, Paychex, CareerBuilder, Avionte, Acquity, Idibu, PivotCX, Talemetry, Gestmax, Scoptalent, Eolia Software, MyCVtheque, Hubspot), with anything outside that list handled as a bespoke integration through sales. No public API, developer portal, API reference, OpenAPI/AsyncAPI specification, webhook catalog, SDK or CLI was ever published: a 557-URL census of the archived seiza.co site shows only marketing, blog, FAQ and legal pages, and every /.well-known/ path returned 404 while the site was live. Seiza was acquired by UK job-search engine Adzuna on 2024-11-18 and folded into Adzuna's social recruitment advertising line; Adzuna's own developer program is profiled separately in this network. The company domain seiza.co was still serving in May 2026 but no longer resolves at all as of 2026-08-17. This profile is retained as a historical company record; there is no API surface to enrich.
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.
Seiza is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — Seiza scores 0.0/100 (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.
Why this profile is thin
Seiza was acquired by Adzuna on 2024-11-18 and has now been fully decommissioned rather than redirected — seiza.co holds a live registration to 2027 but its GoDaddy delegation answers REFUSED, so the apex, www, api, docs and app hosts all return SERVFAIL and no HTTP connection can be opened; the profile's inherited seiza.fr URL is an unrelated GoDaddy Website Builder page ("Find Your Zen") whose only machine-readable file is a GoDaddy-generated llms.txt, and while the real site was live it published 23 pre-built ATS connectors with bespoke integrations routed through sales but never a public API, developer portal or specification of any kind.
This is an honest zero, not a gap in our research. Seiza does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

The organization behind the API
Seiza is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
← All providers · Data indexed from github.com/api-evangelist/seiza · machine-readable index on apis.io
This is an independent, third-party profile of Seiza, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
