description: '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.'

x-website-note: The company site was https://www.seiza.co/ (last archived live 2026-05-15).
  As of 2026-08-17 both seiza.co and www.seiza.co return SERVFAIL — the GoDaddy delegation
  answers REFUSED for the zone — so no HTTP connection can be opened to any host on it.
x-domain-note: https://seiza.fr/ was recorded as this company's website by the Serena
  portfolio harvest, but it is NOT the company. It is an unrelated GoDaddy Website Builder
  placeholder titled "seiza.fr" with the tagline "Find Your Zen", a generic contact form and
  a GoDaddy-generated llms.txt; it sits on ns81/ns82.domaincontrol.com via Key-Systems, was
  re-registered 2024-09-06, and has Wayback history back to 2008 predating the Seiza brand.
  Serena's own portfolio profile names seiza.co. It is deliberately not wired as a Website
  pointer.

  detail: >-
    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.
