Companies Using Osano in London: 513 Active Firms (2026)
London companies running website consent tools manage consent capture, privacy notices and visitor preference choices across city-based organisations.
Adoption usually sits with marketing operations, legal or privacy teams rather than a single IT owner. Companies running this consent-management platform tend to have enough web traffic, paid acquisition or analytics use to make consent evidence worth formalising, but not always a large in-house compliance function. The buying centre is often a hybrid one: marketers need tag control, legal teams need defensible wording, and product or web teams need a preference layer that does not break forms, embedded media or site measurement. That points to organisations past brochure-ware websites, with active go-to-market activity and some budget for privacy operations.

London has 513 companies running this consent-management stack, making the list more a marker of specific privacy tooling adoption than a proxy for the whole city’s digital economy. Reported headcount totals 2,642, so the footprint is visible but skewed towards smaller teams rather than enterprise workforces. The median company profile is modest, with £463,000 turnover and a headcount of 5, while 34 firms have turnover above £5M. Recent incorporations are present but not dominant: 28 firms in the cohort were incorporated since 2022.
Consent tooling sits close to GDPR and ICO expectations because the operational question is not just whether a banner appears, but whether consent choices are specific, withdrawable and evidenced across analytics, advertising and embedded services. The surrounding stack points to that problem: web security and delivery services appear alongside the consent layer on 80.7% of sites, analytics tools on 53.8%, bot-prevention tools on 38.4%, content-management systems on 32.0%, and tag managers on 27.3%. Procurement therefore tends to involve both marketing systems owners and whoever signs off privacy risk.
Adoption appears likely to track the messier parts of digital marketing rather than the privacy function alone. Firms with paid acquisition, embedded media and outsourced web development tend to need consent tooling earlier, while smaller service businesses can remain on basic banner patterns for longer. The direction of travel has been towards tighter integration with tag governance and privacy notices, partly because browser changes and regulator scrutiny make passive consent harder to defend. Consolidation among consent, privacy-operations and website-governance tools may also blur category boundaries, leaving buyers to choose between specialist consent layers and broader compliance suites.

Key facts
About 6% of the trading cohort reports turnover above £5M (34 of 513 firms) — the rest sits below that revenue band.
5% of the cohort was incorporated since 2022 (28 firms), so a sizeable share is in its first few filing cycles.
80.7% of the cohort also run a website traffic-management or security layer, pointing to consent tooling inside broader web-governance stacks.
Analytics and tag-management tooling appears alongside the consent layer in 53.8% and 27.3% of cases respectively, suggesting many London users are managing consent around measurement workflows.
Real Estate & Property is the largest tagged sector at 21.4%, followed by Recruitment & Staffing at 12.3% and SaaS at 8.0%.
Credit risk is mixed: 9.0% are marked distressed and 19.1% weak, so supplier and prospect screening should not treat consent-tool use as a proxy for financial resilience.
There are 1,151 verified directors across the London cohort, giving sales and research teams more than two named contacts per active user on average.

How Osano 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.
