B2B Companies Using Leadsy in the UK: 69 Active Firms (2026)
B2B companies running lead-capture website technology identify and qualify inbound business prospects, with UK marketing governed by ICO, PECR and GDPR rules.
Sales and marketing operations, rather than IT alone, tend to own this stack in B2B suppliers. The job is practical: identify commercial visitors, enrich forms, route enquiries and give sales teams a reason to follow up while the buying intent is still warm. Adoption usually points to a company with enough inbound traffic to justify dedicated demand-generation process, some CRM discipline, and a sales motion where a missed website visit may be commercially material. The fit is less obvious for consumer businesses or firms whose pipeline is built almost entirely through tenders, channel partners or offline referrals.

UK adoption is a narrow slice of the business-to-business software and services market: 69 active trading companies run the technology. Reported headcount attached to adopters totals 763 people, which puts the footprint closer to lean commercial teams than to large enterprise sales organisations. Its 1.8% share of detected marketing-tool use leaves it towards the lower end of the category comparison. Registered-office skew is also clear: London accounts for 37.7% of the cohort and the South East for 20.3%, with smaller clusters in the South West, North West and North East.
B2B adoption sits inside an activity-specific regulatory regime, not a sector licence. ICO guidance treats PECR as relevant to live or automated calls, electronic mail and fax, while UK GDPR still applies where business-contact personal data is processed. The electronic-mail consent rule is narrower for corporate subscribers, but senders still need to identify themselves and provide a valid opt-out route. Live marketing calls require screening against CTPS and TPS, and organisations should not call businesses that have objected. For users of visitor-identification technology, the practical risk sits in provenance, consent records, suppression and hand-off into sales workflows.
Adoption appears likely to be shaped less by fashion than by proof thresholds inside commercial teams. Buyers tend to ask whether visitor identification changes follow-up quality, not whether it adds a marketing dashboard. Privacy expectations may push users towards clearer notices, cleaner suppression processes and closer alignment between marketing operations and sales development. The category also looks exposed to bundling, as adjacent analytics, CRM and enrichment tools fold similar functions into broader packages. That may favour vendors with clear data-governance answers, while leaving smaller adopters to use the technology only where inbound volume justifies the operational effort.
Adoption by company size
Adoption of Leadsy varies by company size across the trading UK B2B companies in this cohort. 0.1% of the 76,784 companies with under 10 employees run Leadsy (44 detected). 0.1% of the 31,788 companies with 10–50 employees run Leadsy (23 detected). 0% of the 3,773 companies with over 50 employees run Leadsy (0 detected). That is a 0.1% gap between the over 50 employees and under 10 employees bands.

Key facts
About 1% of the trading cohort reports turnover above £5M (1 of 69 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (5 firms), so a sizeable share is in its first few filing cycles.
Within B2B companies with a detectable marketing system, this lead-capture tool accounts for 1.8% (69) of a 3,913-company denominator, behind systems detected at 7.6% (297), 6.8% (265), 6.3% (248), 6.2% (243) and 6.1% (239).
London accounts for 37.7% (26) of the cohort, followed by the South East at 20.3% (14).
Stack overlap points to analytics-led web operations: 71.0% (49) also run web analytics, 65.2% (45) run tag management and 55.1% (38) show content-management signals.
The most common overlapping sector tags are SaaS at 30.4% (21), marketing agencies at 26.1% (18) and IT services and managed services at 21.7% (15).
ICO guidance places B2B direct marketing under PECR for live or automated calls, electronic mail and fax; UK GDPR still applies where personal data is processed.

How Leadsy 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. B2B 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 B2B 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.
