B2B Companies Using Simpli.fi in the UK: 59 Active Firms (2026)
UK B2B companies running programmatic advertising technology sell to other businesses while using paid-media infrastructure on public websites.
For UK B2B suppliers, this programmatic advertising stack usually sits between demand-generation planning, website tagging and audience retargeting. It tends to point to a supplier with enough paid-media budget to test addressable audience buying, a measurable website, and some in-house or agency support for landing pages, analytics and attribution. The fit is clearest where sales cycles justify targeted reach rather than broad consumer impressions: service firms, trade suppliers, manufacturers and property-related businesses looking to bring known buying groups back into the funnel.

There are 59 actively trading UK B2B companies running this stack, so adoption is visible but narrow. Reported employment across adopters totals 608 people, placing the footprint closer to specialist demand-generation users than to enterprise-wide ad infrastructure. Within the detected advertising-stack comparison, its share is 0.7%, level with another ad-management system and behind paid-search and social-ad buying. Regional distribution tilts towards the South East at 20.3% and London at 16.9%, with the South West and North West both at 11.9% and the North East at 10.2%.
B2B marketing rules sit mainly in privacy and direct-marketing law rather than a sector licence. ICO guidance treats PECR as covering live and automated calls, electronic mail and fax; for corporate subscribers, B2B email and text outreach does not require PECR consent, but the sender must identify itself and provide a valid opt-out route. UK GDPR still applies where business-contact data is personal data. Live B2B calling also needs CTPS and TPS screening, and organisations must not call businesses that have objected. For companies running programmatic media, consent management, tag governance and audience-list handling are therefore procurement issues as much as marketing operations.
Adoption appears selective rather than standard for UK B2B suppliers. The stack tends to fit organisations that have moved beyond search-led acquisition and want account or audience targeting, but many remain small enough for lighter paid-media setups to be adequate. Pressure on consent, cookie use and audience matching is likely to keep procurement scrutiny on tagging and identity workflows. Over time, usage may concentrate among suppliers with longer consideration cycles, higher contract values and agency-supported media operations, while simpler buyers rely on bundled ad platforms and basic analytics.
Adoption by company size
Adoption of Simpli.fi rises with company size across the trading UK B2B companies in this cohort. 0% of the 76,784 companies with under 10 employees run Simpli.fi (35 detected). 0.1% of the 31,788 companies with 10–50 employees run Simpli.fi (21 detected). 0.1% of the 3,773 companies with over 50 employees run Simpli.fi (3 detected). That is a 0.1% gap between the over 50 employees and under 10 employees bands.

Key facts
About 10% of the trading cohort reports turnover above £5M (6 of 59 firms) — the rest sits below that revenue band.
3% of the cohort was incorporated since 2022 (2 firms), so a sizeable share is in its first few filing cycles.
Among B2B firms with a detectable Advertising system, this technology accounts for 0.7% (59) of the 8,626-company denominator.
Registered offices skew outside the capital: the South East accounts for 20.3% (12), London 16.9% (10), and the South West and North West 11.9% (7) each.
B2B firms running the advertising technology are concentrated in operational sectors: Field Services & Trades account for 27.1% (16), Construction 22.0% (13), and Wholesale & Distribution plus Advanced Manufacturing 13.6% (8) each.
Website stack overlap is high, with the largest co-detections appearing on 78.0% (46), 61.0% (36) and 59.3% (35) of sites.
ICO guidance treats PECR as covering direct marketing by live or automated calls, electronic mail and fax, while UK GDPR still applies where business-contact personal data is processed.

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.
