B2B Using Mux in the UK: 152 Active Firms (2026)
B2B companies using online video tools deliver hosted playback, streaming and media workflows for business buyers across the UK.
Hosted video infrastructure usually sits between product marketing, demand generation, sales enablement and customer education. For B2B adopters, the job is less about public broadcasting than controlled playback: webinars, demos, onboarding libraries and media-rich account journeys that need tracking, reliability and hand-off into revenue operations. Adoption tends to signal a company with direct-channel acquisition, a marketing-operations function and enough engineering or web resource to manage embedded media rather than relying solely on generic upload sites. Typical engagements look like recurring platform and integration spend, owned by marketing, product or revenue teams, with procurement becoming more involved as customer records and viewing behaviour enter the workflow.

UK adoption remains selective: 152 actively trading B2B companies run this hosted video stack, and together they report 3,485 employees. In the website-instrumentation ranking, the system sits ninth at 0.3%, well behind general web-analytics and visitor-insight tools. The regional skew is concentrated in the usual business-software centres: London accounts for 39.5% of adopters, followed by the South East at 17.1%, the North West at 11.2%, the South West at 5.9% and the East Midlands at 5.3%.
B2B buyers here do not share a single licensing regime; obligations follow the underlying activity, such as financial services, telecoms, data processing or professional services. Hosted video adds a practical layer to procurement because playback pages, webinar capture and lead-routing can involve business-contact data. The ICO’s position on PECR leaves email and text outreach to corporate subscribers outside the consent rule, but senders still need to identify themselves and offer a valid opt-out. UK GDPR continues to apply where personal data is processed, and live marketing calls need screening against CTPS and TPS where relevant.
Adoption appears likely to remain concentrated among B2B firms that treat video as part of the sales journey rather than as a publishing afterthought. The clearest pull comes from product-led education, recorded events and customer-success libraries, where marketing teams want viewing behaviour to sit near campaign and pipeline workflows. Smaller firms may continue to use general hosting, while scale-ups with compliance review, attribution pressure and in-house web teams tend to justify a specialist stack. Consolidation in adjacent marketing and web infrastructure could also make standalone video decisions more procurement-led over time.

Key facts
About 14% of the trading cohort reports turnover above £5M (22 of 152 firms) — the rest sits below that revenue band.
13% of the cohort was incorporated since 2022 (20 firms), so a sizeable share is in its first few filing cycles.
Mux sits in the long tail of detected analytics use in B2B: 0.3% (152) of the 45,574 companies with a detectable system.
London accounts for 39.5% (60) of Mux-running B2B firms, followed by the South East at 17.1% (26) and the North West at 11.2% (17).
Cloudflare is also detected in 78.3% (119) of the cohort, Google Tag Manager in 65.1% (99) and HubSpot in 61.2% (93), pointing to web-delivered stacks around the video layer.
Overlapping sector tags skew towards SaaS at 36.8% (56), AI & Machine Learning at 15.8% (24) and Marketing Agency at 13.2% (20).
ICO guidance says PECR covers direct marketing by live or automated calls, electronic mail and fax, while UK GDPR still applies where personal data is processed.

How Mux 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.
Mux is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
