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.
