Companies Using Apollo.io in the UK: 381 Active Firms (2026)
UK companies running sales-intelligence technology use website-linked revenue operations tools to identify, enrich and prioritise B2B prospects.
Adoption usually sits in revenue operations rather than IT, with sales development, demand generation and founder-led commercial teams using the stack to turn market lists into prioritised account work. The buyer profile is mostly business-to-business and commercially mature enough to care about outbound coverage, contact freshness and territory focus. That does not necessarily mean a large sales floor: many implementations appear to be run by lean operator-led teams, with larger employers using the same tooling to coordinate prospecting rules, enrichment checks and hand-offs into CRM-led pipeline management.

The UK adoption picture is fairly compact: 381 companies are actively trading and running this sales-intelligence platform. Reported employment totals 1,275 people, which points to a market weighted towards smaller commercial teams rather than heavily staffed sales operations. Several firms span more than one category, but the centre of gravity is business-to-business technology and services: SaaS accounts for 29.4% of the cohort, IT services and managed services for 18.1%, marketing agencies for 15.7%, and AI and machine-learning businesses for 13.6%.
Procurement for this stack tends to involve revenue operations, sales leadership and whoever owns data governance, because contact enrichment, email outreach and website tracking all create audit and consent questions. Buyers are likely to test how contact sources are documented, how suppression lists are honoured, and whether outreach workflows can be separated by jurisdiction or customer segment. The vendor ecosystem also tends to be bundled into wider sales and marketing operations, so switching decisions are rarely just about prospect data; they also touch CRM hygiene, campaign attribution and the hand-off between marketing-qualified interest and sales-owned pipeline.
Adoption appears to be moving away from standalone prospecting licences and towards revenue-workflow bundles that combine enrichment, routing and outbound execution. Smaller teams may keep using a sales-intelligence layer if it removes manual list building, while larger operators tend to fold the same job into broader sales operations architecture. Privacy scrutiny and inbox-deliverability pressure are likely to favour cleaner consent handling, better suppression logic and more selective outreach. Consolidation also looks plausible, especially where firms already run overlapping tools for tracking, enrichment and campaign attribution.

How Apollo.io 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.
