B2B Companies Using Acast in the UK: 114 Active Firms (2026)
B2B organisations running audio-hosting technology sell products or services to other businesses, in a UK cohort identified from public websites.
Marketing, communications and partner teams are the usual buying centres, with audio hosting used to publish podcast feeds, embed episode players, and measure listening behaviour around campaigns. In B2B settings, adoption usually signals a firm with enough marketing operations capacity to manage recurring content, consented contact capture and follow-up workflows, rather than a casual media experiment. The commercial fit is clearest for advisory, financial-services, agency, software and publishing suppliers using expert-led content to warm enterprise or mid-market accounts. Engagements tend to sit alongside web analytics, search optimisation, CRM hand-off and paid social activity, so the technology often appears as part of a wider demand-generation stack.

Across the UK, 114 actively trading B2B organisations are running this audio-hosting stack. Reported employment totals 1,673 people, giving the cohort a modest labour footprint despite its concentration in client-facing services. Within the podcast-hosting category for this sector, the stack takes the runner-up position at 22.7% on a 502-adopter denominator. The registered-address pattern is London-heavy but not London-only: London accounts for 34.2%, followed by the South East at 14.9%, the East of England at 10.5%, the South West at 9.6% and the West Midlands at 8.8%. That spread fits a buyer base skewed towards advisory, wealth, agency, software and publishing firms rather than mass-market media operators.
Business-to-business adoption does not bring a dedicated sector licence; obligations follow the underlying activity, such as financial services, telecoms, professional services or data processing. For firms using audio to generate leads, the practical compliance point is the marketing journey around the episode: newsletter capture, retargeting, sales follow-up and event invitations. The ICO treats PECR as covering direct marketing by live or automated calls, electronic mail and fax. Electronic-mail rules do not apply in the same way to corporate subscribers, but senders still need to identify themselves, provide a valid opt-out route and respect UK GDPR where business-contact data is processed. Live B2B calling also requires CTPS and TPS screening where relevant.
Adoption appears likely to remain concentrated among firms that already invest in content-led sales and account development. Audio hosting tends to be retained where it supports expert commentary, relationship marketing and re-use of webinar or event material; it is more exposed where episodes sit outside the sales workflow. Procurement may drift towards bundled marketing stacks, which could reduce standalone switching unless analytics, brand control or distribution support matter to the buyer. For smaller professional-services and advisory firms, the constraint is less the hosting cost than the editorial routine needed to keep a regular channel credible.
Adoption by company size
Adoption of Acast 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 Acast (70 detected). 0.1% of the 31,788 companies with 10–50 employees run Acast (41 detected). 0% of the 3,773 companies with over 50 employees run Acast (1 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 (2 of 114 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (9 firms), so a sizeable share is in its first few filing cycles.
Within B2B firms with a detectable podcast-hosting system, this audio-hosting technology accounts for 22.7% (114) of a 502-company detectable market, behind the largest detected system at 29.1% (146).
London accounts for 34.2% (39) of the cohort, followed by the South East at 14.9% (17) and the East of England at 10.5% (12).
Co-detected web stack signals skew towards marketing operations: 60.5% (69) also run tag-management technology, 39.5% (45) web analytics and 36.8% (42) paid social advertising tooling.
Sector tags overlap, but the largest visible concentrations are wealth management at 24.6% (28), marketing agencies at 21.9% (25), and media and publishing at 14.0% (16).
B2B marketing activity using business-contact data still falls under UK GDPR; ICO guidance says corporate-body emails and texts do not need PECR consent, but senders must identify themselves and provide a valid opt-out.

How Acast 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.
