SaaS Companies Using Fastly in the UK: 62 Active Firms (2026)
SaaS businesses running a detected edge delivery platform sell subscription cloud applications while using CDN infrastructure in the UK.
For SaaS suppliers, an edge delivery layer usually sits in front of the application, documentation, marketing site and customer-facing assets, handling caching, traffic bursts and low-latency delivery. Adoption tends to signal a web estate that matters commercially: direct acquisition, self-serve onboarding, API documentation or product pages are visible enough to justify specialist infrastructure. The buying centre is usually split between engineering, platform operations and growth or marketing teams, with procurement becoming more formal where public-sector, financial-services or regulated customers are involved. Engagements are less about project hosting and more about ongoing performance, reliability and data-handling assurance.

Among UK SaaS adopters, 62 companies are actively trading with this edge platform detected. The platform sits fourth in the CDN ranking for the sector, with a 1.8% detected share across a 3,409-company denominator, so it is a niche choice rather than a default layer. Reported employment totals 1,511 people across the cohort. The registered-office skew is London-heavy: London accounts for 43.5%, followed by the South East at 24.2%, the South West at 8.1%, the East of England at 6.5% and the East Midlands at 4.8%.
UK SaaS suppliers are not licensed as a single class, so regulatory exposure follows the use case rather than the delivery model. Companies running edge infrastructure still need to manage UK GDPR and Data Protection Act 2018 obligations where personal data, logs or customer identifiers pass through cloud-hosted software. The ICO is the relevant data-protection regulator. Procurement can also be shaped by client-sector controls: buyers in financial services, government or other regulated markets often ask for security evidence, contractual data-processing terms and incident-response processes. The CMA’s cloud-infrastructure work matters because it reported an adverse effect on competition and pointed to remedies, but it does not create a separate licensing regime for SaaS providers.
Adoption appears to sit with SaaS firms that treat website performance, documentation delivery and uptime as part of the product experience rather than a marketing afterthought. The cohort has a long-tail feel: many users look like lean commercial software suppliers, while only a smaller group has moved into higher-revenue, procurement-heavy accounts. Future movement is likely to be shaped by migration pressure from bundled cloud platforms, sharper scrutiny of data flows and a preference for fewer vendors in the web stack. Specialist edge layers may remain relevant where latency, cache control or traffic spikes affect renewal risk.
What’s in the file
One row per company, 50+ columns — everything below plus each company’s verified directors, from Companies House filings.
Company data
Verified directors — included
Active director count is the full Companies House board, so it can be higher than the number of names listed — we leave out nominee and formation-agent directors, who aren’t worth contacting. It’s blank for the small number of companies whose officers we haven’t fetched yet.
You’re charged per business, not per row. Where a business trades through several registered companies you get every one, and the Group Primary column marks one row per business — filter to those and the count matches your invoice. Rows sharing a website are not automatically one business: franchises and multi-site operators each count separately, and where names don’t prove a relationship we count them apart rather than guess.
Adoption by company size
Adoption of Fastly rises with company size across the trading UK SaaS companies in this cohort. 0.1% of the 37,913 companies with under 10 employees run Fastly (43 detected). 0.8% of the 1,886 companies with 10–50 employees run Fastly (16 detected). 2.4% of the 166 companies with over 50 employees run Fastly (4 detected). That is a 2.3% gap between the over 50 employees and under 10 employees bands.

Key facts
About 12% of the trading cohort reports turnover above £5M (8 of 62 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (4 firms), so a sizeable share is in its first few filing cycles.
Among SaaS firms with detectable CDN infrastructure, the selected CDN appears on 1.8% of 3,409 companies with a detectable system.
London accounts for 43.5% (27) of the CDN-running SaaS cohort, followed by the South East at 24.2% (15).
Tag-management tooling is also detected on 61.3% (38) of the cohort, while a second CDN appears on 58.1% (36).
SaaS providers processing personal data need to consider UK GDPR and Data Protection Act 2018 obligations, with the ICO as the relevant UK data-protection regulator.
The CMA closed its UK public-cloud infrastructure services case on 31 July 2025 after finding an adverse effect on competition and recommending strategic market status investigations into the two largest cloud infrastructure providers.

How Fastly 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. SaaS 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 SaaS 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.
