B2B Companies Using Filestack in the UK: 52 Active Firms (2026)
UK B2B companies running file-upload technology sell products and services to other organisations across regulated and non-regulated markets.
For business-to-business adopters, file-upload tooling usually sits inside intake rather than marketing decoration: proposal portals, onboarding forms, supplier-registration journeys, evidence submission and media hand-off. Buying centres tend to be product, operations and revenue teams, with finance, compliance or IT involved where uploaded material contains contracts, identity documents or client records. Adoption usually signals a company has moved beyond simple contact-form capture, but not necessarily into enterprise platform procurement. The cohort looks weighted towards small and mid-market organisations that need managed upload handling without building every storage, validation and user-experience control themselves.

Across the UK, 52 companies are actively trading with this file-upload stack visible on their public websites. Reported employment is 303 people across 38 of 38 firms reporting headcount (100%), so the footprint is closer to specialist teams than large operational estates. Within detected CDN usage among business-to-business companies, the stack accounts for 0.2%, placing it near the foot of the category ranking. Regionally, London accounts for 30.8% of the cohort, followed by the South East at 17.3% and the North West at 13.5%.
File-upload workflows bring privacy obligations earlier in the sales and onboarding journey, because submissions can contain names, business-contact details, contracts, images or supporting documents. UK business-to-business activity is not licensed as a single market; financial services, telecoms, professional services and other regulated activities carry their own rulebooks. For marketing, the ICO treats PECR as covering live and automated calls, electronic mail and fax. The electronic-mail rule does not apply to corporate subscribers, but senders must identify themselves and provide a valid opt-out route. Live marketing calls still require CTPS and TPS screening where businesses have objected.
Adoption appears likely to remain selective rather than universal. Many business-to-business firms can use form builders, cloud storage and customer-relationship systems for ordinary document capture, so a dedicated upload layer tends to appear where intake volume, file size, validation or user experience becomes awkward. Procurement may also move through wider website and application rebuilds rather than standalone buying cycles. Over time, bundling by adjacent infrastructure and workflow vendors may narrow the visible market for specialist upload tooling, while regulated onboarding and media-heavy workflows should keep a place for dedicated services.
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 Filestack varies by company size across the trading UK B2B companies in this cohort. 0% of the 76,784 companies with under 10 employees run Filestack (38 detected). 0% of the 31,788 companies with 10–50 employees run Filestack (14 detected). 0% of the 3,773 companies with over 50 employees run Filestack (0 detected).

Key facts
About 1% of the trading cohort reports turnover above £5M (1 of 52 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (4 firms), so a sizeable share is in its first few filing cycles.
Within B2B firms with a detectable CDN system, this file-upload technology appears in 0.2% of the 31,675-company detectable base (52 firms).
The cohort skews towards London at 30.8% (16), followed by the South East at 17.3% (9) and the North West at 13.5% (7).
Usage overlaps with analytics and hosting infrastructure: 76.9% (40) also run web analytics, while 65.4% (34) also run cloud hosting services.
The largest sector overlaps are Media & Publishing at 19.2% (10), Venture Capital at 15.4% (8), and Wholesale & Distribution at 13.5% (7).
B2B marketing is activity-regulated rather than licence-regulated: ICO guidance says live B2B marketing calls must be screened against CTPS and TPS, while UK GDPR still applies where personal data is processed.

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