B2B Companies Using Spline in the UK: 59 Active Firms (2026)
B2B companies using interactive web graphics sell products or services to other organisations across the UK.
For business-to-business organisations, interactive spatial web graphics usually sit in the sales-and-marketing stack rather than core operations: product explainers, animated service journeys, configurator-like pages and campaign microsites. Adoption tends to signal a company that has moved beyond a brochure site, with enough internal marketing or design ownership to brief external developers, maintain page performance and connect website engagement to lead generation. The buying centre is usually marketing, growth or product marketing, with input from web engineering where accessibility and analytics are involved. Engagements are rarely enterprise-wide platform decisions; they are more often discrete website or campaign projects for complex propositions.

UK adoption is a small, concentrated slice: 59 actively trading business-to-business companies run this interactive graphics stack. Within detected JavaScript graphics usage, the system ranks third, accounting for 25.9% of a 228-site denominator. Registered addresses skew towards London, at 50.8%; the North West and East Midlands each account for 8.5%, followed by the East of England and South East at 6.8% each. Reported headcount totals 560 across the adopters with employment disclosures, which points to a cohort weighted towards lean commercial and technical teams rather than large corporate estates.
Running interactive graphics on a public website does not create a single licensing burden. The obligations sit around the underlying business activity and the website’s lead-capture workflow. Financial-services, telecoms or professional-services adopters may face their own sector rules, while marketing operations still need to reflect ICO guidance. PECR covers direct marketing by live or automated calls, electronic mail and fax; corporate-subscriber email rules are lighter, but senders still need to identify themselves and provide a valid opt-out route. Where business-contact data is used, UK GDPR applies, and live business marketing calls need screening against CTPS and TPS where relevant.
Adoption appears tied less to novelty and more to the need to explain abstract services before a sales conversation. The cohort tends to favour lean sites with marketing-stack integrations, so future use is likely to be shaped by performance budgets, design-system governance and whether sales teams can prove that interactive pages help qualify leads. As website platforms bundle more visual tools, specialist graphics layers may face pressure from simpler native features. The more durable users are likely to be firms with complex products, longer consideration cycles and enough web ownership to keep interactive content maintained.
Adoption by company size

Key facts
About 5% of the trading cohort reports turnover above £5M (3 of 59 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 B2B firms with a detectable JavaScript graphics system, this interactive-graphics tool accounts for 25.9% (59) of a 228-company denominator, behind two other detected systems at 48.7% (111) and 26.3% (60).
London is the main registered-region cluster for B2B firms running the interactive-graphics tool, at 50.8% (30), followed by the North West and East Midlands at 8.5% (5) each.
Stack pairings skew towards wider website infrastructure: 66.1% (39) also run a network/security layer, 50.8% (30) a hosted site builder, 49.2% (29) tag management and 47.5% (28) web analytics.
Marketing agencies and SaaS suppliers each make up 23.7% (14) of the cohort, with AI and machine learning businesses at 22.0% (13) and IT services or managed services at 18.6% (11).
B2B direct marketing has channel-specific rules: the ICO says PECR covers live or automated calls, electronic mail and fax, while UK GDPR still applies when business-contact data is processed.

How Spline 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
