Companies Using Popup Maker in London: 70 Active Firms (2026)
Companies using onsite popup software run website overlays for consent, lead capture or promotions, with headquarters or operations in London.
Marketing and ecommerce teams usually own this stack, with compliance input when consent prompts or behavioural tracking are involved. Users tend to be traffic-dependent businesses rather than back-office operators: property agents, course providers, travel operators, managed-service firms and trades marketplaces all need to turn anonymous visits into enquiries, bookings or subscribers. Adoption usually signals a website maintained by a small growth or digital team, enough budget for conversion tooling and analytics, and campaign rhythms that make timed messages, list-building and consent capture worth managing. Engagements are typically light-touch compared with enterprise software, but they still sit close to revenue attribution and privacy governance.

London has 70 actively trading companies running onsite overlay tooling, making this a small but visible adoption cohort rather than a broad horizontal software market. Reported employment totals 877 people across the cohort, which points to a user base skewed towards lean commercial and operational teams. The mix is not confined to digital-native sectors: real estate and property, education and training, travel and hospitality, IT services and field-services users all appear in the cohort. That spread fits a technology bought for measurable website actions, where enquiry capture, campaign testing and consent handling matter more than deep systems integration.
Onsite conversion tooling is not usually licensed as a standalone UK activity, but common uses sit inside privacy and electronic-marketing rules. The ICO’s PECR cookies guidance requires organisations to tell users when cookies or similar device-access technologies are used, explain their purpose and obtain consent that is actively and clearly given. Non-essential tracking should not be triggered before consent, including on the first page a visitor lands on. Where popup interactions, tags or audience segments involve personal data, the Data Protection Act and UK GDPR also apply. IAB UK remains relevant for advertising-market practice across media owners, agencies, ad tech and brands.
Adoption appears likely to keep moving towards consent-led personalisation rather than untargeted interruption. Companies running this kind of tooling tend to face pressure from browser privacy changes, tighter scrutiny of tracking consent and the bundling of popups into wider website, ecommerce and marketing platforms. That may reduce the visibility of standalone overlay tools, even where the underlying workflow remains. For smaller London users, the deciding factor is likely to be operational fit: whether a lean marketing team can manage prompts, lists, tests and consent evidence without adding another layer of process.
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 Popup Maker rises with company size across the trading companies in this cohort. 0% of the 532,485 companies with under 10 employees run Popup Maker (45 detected). 0.2% of the 15,364 companies with 10–50 employees run Popup Maker (25 detected). 0.2% of the 1,763 companies with over 50 employees run Popup Maker (4 detected). That is a 0.2% gap between the over 50 employees and under 10 employees bands.

Key facts
About 5% of the trading cohort reports turnover above £5M (4 of 70 firms) — the rest sits below that revenue band.
4% of the cohort was incorporated since 2022 (3 firms), so a sizeable share is in its first few filing cycles.
The London onsite-popup cohort is anchored in marketing-site stacks: 100.0% also run the same website platform, while 62.9% also show a search-optimisation layer.
Analytics and tag management commonly sit alongside the overlay layer, with 60.0% showing an analytics tag and 51.4% showing tag-management tooling.
The largest sector tags are Real Estate & Property at 12.9% (9), Education & Training at 11.4% (8), and Travel & Hospitality at 11.4% (8).
ICO PECR guidance requires organisations setting cookies to explain what the cookies do and why, and to get consent that is “actively and clearly given”; non-essential cookies cannot be set on a homepage before consent.
IAB UK says the UK digital ad market reached £40.5 billion in 2025, up 10% year on year, giving onsite engagement and consent tools a sizeable demand backdrop.

How Popup Maker 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.
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.
