The register
Persefoni Ltd is licensed to sponsor on Global Business Mobility: Senior or Specialist Worker and Skilled Worker. Its entry on the register dates back to at least 2026, and the organisation is based in London. The register records its rating as Worker (A rating).
Companies House lists it as Persefoni Ltd, number 13567342, incorporated 2021: 5 years of filings behind the name. The registered office is at 5 New Street Square, London, EC4A 3TW, EC4A 3TW. Its filed activity puts it in business services.
A licence says an organisation may sponsor; it does not say it is hiring today. The way to find out is the same as for any employer: the careers page, the job boards, and a direct approach with a UK-style CV that says early that sponsorship would be needed.
