Companies Using Greenhouse in the UK: 258 Active Firms (2026)
Companies using Greenhouse run website-linked hiring workflows for applicant capture and recruitment operations across the UK employer market.
Careers-site ATS adoption usually sits with talent acquisition, people operations and finance, rather than with purely technical buying teams. The signal points to employers with a dedicated hiring owner, repeatable role intake, interview scheduling and reporting needs, rather than ad hoc recruitment managed only by line managers. Procurement tends to involve legal and security as well, because candidate records, job adverts and source tracking sit on public web infrastructure. The presence of this stack usually marks companies that have moved beyond occasional vacancies into multi-role hiring across commercial, operational, technical or seasonal functions.

UK adoption is visible across 258 active trading companies, a small but distinct slice of employers exposing a website-linked recruitment stack. Reported employment across the cohort totals 3,223 people, which points to a concentration among smaller operating companies and hiring teams that still need structured applicant handling. The sector mix skews towards software, finance-adjacent and travel or hospitality employers, rather than being confined to one hiring model. Many appear to use the stack alongside analytics, consent-management and hosting infrastructure, suggesting public careers pages are treated as part of a wider go-to-market and operations surface.
Candidate data, not protected-crop compliance, is usually the live issue for this technology signal. Defra and APHA plant-health controls, plant passports and phytosanitary certificates matter to growers moving regulated plants or plant products; they do not explain most careers-site adoption. Employers running a public hiring platform need clear accountability around GDPR notices, lawful basis, retention periods, candidate access requests and processor contracts. Procurement tends to pull in people operations, legal and security because applicant records, assessment notes and source tracking move between the careers page, internal systems and external recruitment suppliers.
Adoption appears tied to employers professionalising hiring before they build a large talent-operations function. The stack tends to persist where hiring managers need consistent workflows, interview feedback loops and audit trails, but it can be challenged when broader HR suites bundle applicant tracking into payroll, workforce management or people analytics. Migration pressure is likely to come from procurement scrutiny, privacy reviews and the wish to reduce overlapping tools. The cohort therefore looks less like a speculative software frontier and more like a practical marker of companies with recurring recruitment needs, external candidate pipelines and enough internal process to justify a dedicated system.

How Greenhouse usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
Greenhouse is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
