Companies Using PostHog in the UK: 270 Active Firms (2026)
UK companies running product analytics tools on their websites track visitor behaviour, funnels and conversion signals across digital customer journeys.
Event-based product analytics sits between marketing analytics and application telemetry, logging accounts, users, sessions and feature-level actions so teams can inspect funnels, activation paths and retention. Companies running this stack usually have product, growth and engineering as the main buying centres, with marketing involved where acquisition attribution still sits close to the website. Adoption tends to signal an in-house digital team, a live onboarding or conversion problem, and enough technical capacity to maintain event quality. Engagements are practical: event taxonomy, tracking governance, dashboard design and funnel review, rather than multi-year enterprise programmes.

270 actively trading UK companies are running this analytics stack, making adoption visible but still selective among digital businesses. The cohort is not simply a micro-business tail: 15 companies record turnover above £5M, although most sit below that threshold and appear closer to early-commercial or specialist digital operators. Reported employment totals 1,664 people, which fits a market where in-house product and engineering capacity exists, but full enterprise data teams are not always present. The incorporation profile also points to recent formation, with 43 companies established since 2022.
Product analytics adoption sits inside a more awkward compliance zone than plain performance monitoring. Where event streams connect browser identifiers, account IDs, email-derived user keys or in-product behaviour, teams need a defensible privacy basis and clear cookie or storage consent when collection is not essential to delivering the service. Procurement often turns on data-processing terms, retention controls, sub-processor disclosure and whether engineers can remove personal fields from event payloads. For regulated customers, the issue is less the dashboard and more whether experimentation, attribution and behavioural scoring can be audited without creating avoidable personal-data exposure.
Adoption appears likely to follow the same shape as product-led software adoption more generally. Smaller teams tend to start with funnel visibility and session-level diagnosis, then add experimentation or warehouse links once product ownership matures. Some users will consolidate analytics, feature flagging and customer messaging into fewer tools, while others will keep specialist stacks because engineering teams want control over event capture and storage. Privacy pressure should keep procurement scrutiny relatively high. Scale-up scarcity also suggests a long tail of light deployments, with a smaller group treating behavioural analytics as part of core revenue operations.

Key facts
About 5% of the trading cohort reports turnover above £5M (15 of 270 firms) — the rest sits below that revenue band.
15% of the cohort was incorporated since 2022 (43 firms), so a sizeable share is in its first few filing cycles.
72.2% of the cohort also run a CDN and security layer, suggesting product analytics often sits inside a wider performance and security stack.
66.7% also run a tag-management layer, while 50.7% also run a general web-analytics tool.
SaaS is the largest sector tag at 44.1% of the cohort, followed by startup-tagged firms at 26.7% and AI & Machine Learning at 17.8%.
Financial-health scores are mixed: 23.3% sit in the highest band, 25.6% in the middle band and 9.6% are marked distressed.

How PostHog 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.
