B2B Companies Using Herefish in the UK: 184 Active Firms (2026)
B2B technology adopters sell products or services to other organisations while running specialist public-site software in the UK.
In recruitment and staffing, this marketing-automation stack usually sits between the job board, the candidate database and the sales CRM. It supports lead capture, candidate nurture, client reactivation and account-based outreach, so adoption tends to signal a firm with a direct-channel posture rather than a purely relationship-led sales model. Buyers are usually sales operations, marketing operations or senior commercial teams serving corporate hiring clients. Engagements are more likely to involve configuration, data hygiene and ongoing campaign governance than a standalone website install, which points to operators with some budget for automation and compliance process.

Across the UK, 184 active UK companies run this system in recruitment and staffing, placing it ninth in the marketing-automation category at 1.9% on a category denominator of 9,511. Reported headcount totals 2,887, with headcount disclosed across all organisations that publish employment information. The registered-address skew is London (28.8%), the South East (16.3%), East of England (11.4%), North West (11.4%) and South West (7.1%). The pattern points to adoption by sales-led recruiters with client-service density in London and the South East, rather than a broad horizontal business-software footprint.
Business marketing in the UK is activity-regulated rather than licensed through a single industry regime. For recruitment and staffing users of marketing automation, the practical boundary is usually contact permission, identity disclosure and suppression management. ICO guidance treats PECR as covering direct marketing by live or automated calls, electronic mail and fax; the electronic-mail consent rule is different for corporate subscribers, but senders still need a clear identity and a valid opt-out route. UK GDPR continues to apply where business contacts are personal data. Live-call workflows also need screening against the relevant business and individual preference registers, and prior objections have to be honoured.
Adoption appears tied to recruitment firms that already run a direct candidate and client communications machine, rather than to agencies relying on job boards and manual follow-up. The stack tends to suit operators with enough inbound volume to justify workflow design, suppression controls and attribution work. Usage may become more selective as broader CRM suites bundle basic messaging and reporting. Firms with mature sales operations are likely to keep specialist automation where it links candidate nurture with account development, while smaller agencies may default to bundled tools inside website or back-office packages. Consolidation pressure is therefore more likely to appear as quiet vendor switching than as a visible new-adopter wave.
Adoption by company size
Adoption of Herefish rises with company size across the trading UK B2B companies in this cohort. 0.1% of the 76,784 companies with under 10 employees run Herefish (87 detected). 0.3% of the 31,788 companies with 10–50 employees run Herefish (81 detected). 0.3% of the 3,773 companies with over 50 employees run Herefish (12 detected). That is a 0.2% gap between the over 50 employees and under 10 employees bands.

Key facts
About 15% of the trading cohort reports turnover above £5M (28 of 184 firms) — the rest sits below that revenue band.
2% of the cohort was incorporated since 2022 (5 firms), so a sizeable share is in its first few filing cycles.
Within B2B firms with a detectable marketing-automation system, this system accounts for 1.9% (184) of the category footprint, against a denominator of 9,511 companies.
The cohort is heavily concentrated in Recruitment & Staffing, which accounts for 96.2% (177) of tagged firms; IT Services & Managed Services appears much smaller at 3.8% (7).
London accounts for 28.8% (53) of registered addresses, followed by the South East at 16.3% (30), with the East of England and North West each at 11.4% (21).
Website instrumentation is common: 63.0% (116) also run analytics tracking, 52.7% (97) run bot-screening or form-protection tooling, and 42.9% (79) run tag-management tooling.
For B2B marketing, ICO guidance says PECR covers direct marketing by live or automated calls, electronic mail and fax, while UK GDPR still applies where personal data is processed.

How Herefish 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. B2B companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of B2B companies with a detectable system — not of all UK companies.
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.
