How we know

Read from the source, not self-reported

Every number on this page can be traced to a page we crawled or a posting we read. Full methodology →

  • Job postingsRead hourly from the applicant tracking systems behind British career sites. A tool counts when the employer's own text names it as the team's system.
  • CountryFrom the company's own website: imprint, address, phone prefix and language, with a confidence score. Not the posting's location.
  • Website and DNSScripts and embeds on the company's pages, plus SPF, DKIM, MX and CNAME records of its domain that point at the vendor.
  • ExclusionsJob boards, portals and aggregators are kept out of company lists.
FAQ

rocketseed in United Kingdom: questions

Is this every British company on rocketseed?

It is every British company whose website, DNS records or own job postings show it: 290 in total. Companies that use rocketseed without any public trace are not counted.

What does "United Kingdom" mean here?

The country of the company, from its own website (imprint, address, phone prefix, language), not where the posting is located. A German company hiring in Paris still counts as German.
