Marketing Agency Companies Using Apollo.io in the UK: 60 Active Firms (2026)
Marketing agencies using sales-intelligence technology identify, enrich and contact B2B prospects within UK rules for data protection and direct marketing.
For marketing agencies, this kind of sales-intelligence stack sits between new-business, paid media and account-management teams. It helps turn target-account planning into workable prospect lists, enriches incomplete CRM entries and gives outsourced growth teams a repeatable outbound process rather than ad hoc research. Adoption tends to signal an agency with a direct-channel posture: B2B clients, campaign delivery staff who can handle segmentation, and enough commercial budget to pay for prospecting infrastructure alongside analytics, tagging and site-conversion tools. The fit is usually clearest for agencies selling demand generation, search, content, account-based marketing or outsourced sales support to other businesses.

Across the UK, 60 trading marketing agencies run this sales-intelligence platform. Reported employment totals 880 people, giving the cohort a visible but still fairly small labour footprint. Within the sector’s detected CRM and sales-intelligence stack, the platform accounts for 16.8% of installations, fourth in the ranking behind three more common systems. Registered-address concentration is also clear: London accounts for 35.0% of the cohort, followed by the South East at 16.7%, the South West at 11.7%, the North West at 10.0% and the West Midlands at 8.3%.
Marketing agencies are not licensed as a sector, but campaign execution touches several rulebooks. The ICO regulates data protection and PECR where agencies source, enrich or contact prospects on behalf of clients. The ASA applies the CAP Code to advertisers, agencies and media, while the CMA, trading standards and Ofcom sit around unfair-trading and communications-network misuse. The DMA code adds a trade-body layer for members. For agencies running sales-intelligence systems, procurement diligence tends to focus on lawful basis, suppression handling, client-vendor roles, audit trails and how prospect data moves between CRM, tagging and campaign tools.
Adoption appears likely to remain tied to agencies with outbound-led new-business models rather than the whole marketing-agency base. Lean teams tend to value enrichment and workflow consolidation, but compliance review can slow roll-out when client campaigns cross email, phone and paid-media channels. The scarcity of larger agencies in this cohort suggests that enterprise-scale buyers may keep similar functions inside broader CRM, analytics or customer-data platforms. Smaller agencies are more likely to switch tools as bundling changes, especially where prospecting, sequencing and reporting are sold through the same commercial workflow.
Adoption by company size
Adoption of Apollo.io varies by company size across the trading UK marketing agency companies in this cohort. 0.1% of the 54,246 companies with under 10 employees run Apollo.io (33 detected). 1.5% of the 1,903 companies with 10–50 employees run Apollo.io (28 detected). 0% of the 146 companies with over 50 employees run Apollo.io (0 detected). That is a 0.1% gap between the over 50 employees and under 10 employees bands.

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. marketing agency 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 marketing agency 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.
