Companies Using VWO in London: 134 Active Firms (2026)
London companies running website experimentation tools test and optimise digital journeys from sites based across the capital.
Adoption usually sits with growth, product and digital trading teams rather than IT alone. Companies running this experimentation stack tend to have public web journeys where small changes in forms, pricing pages or onboarding copy can be tested against revenue, lead quality or self-service completion. The stack sits between analytics, content management and page delivery, so adoption usually signals dedicated marketing operations, some engineering capacity and a commercial tolerance for controlled experiments. Engagements are normally subscription licences with implementation support, governance, tagging work and analyst time, not a short campaign purchase.

London has 134 actively trading companies running this website experimentation stack, a cohort large enough to show repeat adoption patterns but still concentrated around firms with visible digital acquisition or self-service journeys. Reported employment across the cohort totals 3,379 people. That footprint points to adoption beyond very small website owners: many users appear to have enough staff for marketing, product or analytics specialists, while still falling short of the scale normally associated with multi-country experimentation programmes.
Experimentation tooling sits close to privacy and consent decisions because it changes what visitors see and how behavioural signals are measured. Tag-management tooling is present on 92.5% of this cohort’s websites, while web-analytics tooling appears on 40.3%, so the testing layer rarely sits alone. Consent design, cookie categorisation and test-audience handling therefore sit close to GDPR and ICO guidance, especially where page variants change pricing, eligibility wording or lead-capture flows. Procurement also tends to involve marketing operations and engineering, because scripts can affect page speed, accessibility and measurement integrity.
Adoption appears tied to the maturity of digital acquisition rather than company age. Firms with subscription, ecommerce or lead-generation funnels tend to keep testing platforms once workflows are embedded, but procurement pressure may push some towards bundled analytics, consent and personalisation suites. Browser privacy changes are likely to favour server-side measurement, cleaner tagging and tighter experiment governance. Smaller users may reduce tool overlap; larger teams are more likely to formalise testing ownership across product, marketing and engineering.

Key facts
About 22% of the trading cohort reports turnover above £5M (30 of 134 firms) — the rest sits below that revenue band.
8% of the cohort was incorporated since 2022 (11 firms), so a sizeable share is in its first few filing cycles.
Tag-management tooling appears alongside the experimentation deployment at 92.5% of London users (124 firms), suggesting testing is usually connected to wider measurement controls.
Website-security and delivery tooling is present at 73.9% of the cohort (99 firms), which fits use cases tied to public, traffic-sensitive web journeys.
Content and search stacks remain common: 47.8% also run CMS software (64 firms), while 39.6% use SEO plug-ins (53 firms).
SaaS is the most frequent sector tag at 38.1% (51 firms), followed by scale-up at 12.7% (17 firms), fintech at 11.9% (16 firms) and AI & Machine Learning at 11.2% (15 firms).

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.
