Companies Using Leadinfo

I expected a smaller Leadfeeder. What came out is a Dutch sales tool bought mostly by small Benelux B2B firms, now putting a Canadian acquisition's snippet on its customers' sites. Our October 2026 crawl counts 24,503 live domains loading Leadinfo's tracker, 19,484 of them matched to a company, 6th in Visitor Identification with 7.42% of the category.

A domain counts when its pages load Leadinfo's script from cdn.leadinfo.net or cdn.leadinfo.eu, its companion host ldnfrpl.com, or create the tracker's JavaScript objects. I tested that rule in a browser on 100 random domains from the set. 92 loaded Leadinfo, 2 sat behind bot walls and 6 didn't, one of them a suspended hosting account and one a 404. The count is sound.

Flat once the crawl settles

The chart reads 20,303 domains in June 2026, 22,729 in July, 23,134 in August, 24,339 in September and 24,503 in October. I wouldn't call that growth. The set of domains we crawl turns over every month, with dead sites dropping out and new ones found, and our detection widened over the same months. Since we started tracking Leadinfo on 16 March 2026, 4,150 domains dropped it on at least one hostname, 16.9% of today's count. When we re-checked the leavers in October, 616 still ran it on another hostname.

"Leadinfo's footprint reads like a Dutch company's sales territory. Almost half the matched customers are in the Netherlands, and the account keys say they bought it themselves." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: treat Leadinfo as a stable pool of about 24,500 domains. The leavers and the dual-tag sites below say more than the trend line.

One account per site

Visitor-identification tags are keyed. Leadinfo's snippet carries the customer's account code, LI- followed by 13 characters, so an agency or platform pushing one account across many client sites would show up at once. It doesn't. The 89 sites in my random sample that exposed a key had 89 different keys. The clusters that do exist are forwarding domains: a translation agency's 45 lookalike domains that all redirect to its main site, and about 30 domains of HIAG, the Swiss property company, on an older Leadinfo host. Across the clean set, 1,654 domains (6.76%) share their page title with at least two others, which is the alias overhead to expect when you turn this domain list into an account list.

That older host deserves a note. 328 domains load a script from ltracking.de, which now redirects to leadinfo.com. On every account I tested, the script is an empty function: it loads and does nothing. Unless a site also loads the current tracker, treat it as a lapsed install.

Sales signal: dedupe by redirect target and you are left with close to one company per row. This is a list of direct customers, not an agency's portfolio.

A Benelux product

9,013 of the 19,484 matched domains belong to Dutch companies, 46.26%. Belgium adds 2,526 and Germany 2,306, so the Netherlands and Belgium alone hold 59.2%. The United States is fourth with 1,107, about one American company for every eight Dutch ones, and the United Kingdom fifth with 1,015. Denmark is sixth with 611. Leadinfo's January 2026 announcement names the Netherlands, Germany, Belgium, the UK and Denmark as its markets, and our map matches that list.

Sales signal: for a CRM integration, a Dutch-language SDR service or a Benelux data product, this is a dense Dutch B2B list from a single tag.

Visitor Queue next to the Leadinfo tag

Leadinfo bought Visitor Queue, a Canadian visitor-identification company, in January 2026, and the integration is already on live pages. Some Leadinfo customers now carry a second snippet, Visitor Queue's tracking and personalisation script, and its id starts with the same characters as the site's Leadinfo key. 16 of the 67 Leadinfo installs in our company sample had it, and 4 of the 92 in the random sample; on 18 of those 20 the ids matched. That is the main reason Visitor Queue shows on 5.22% of Leadinfo domains in our stack data. It is one customer account, not a second purchase.

Sales signal: anyone sizing Visitor Queue's North American base from website tags should take Leadinfo-issued snippets out first. For Leadinfo's own team, the 1,107 American and 1,015 British companies are the base the acquisition was bought to grow.

Who buys it

44.61% of matched companies with a known size have 1 to 10 employees and 37.71% have 11 to 50. The second number is the telling one. A tool that hands leads to a sales team needs a sales team, and Leadfeeder's profile shows nearly the same 11 to 50 share (37.96%). Only 167 companies have more than 1,000 staff, and they often run Leadinfo on one division's site: Kubota on its engine division, Mammoet on its used-equipment shop, 5CA on an event page. By age, 35.24% were founded in the 2010s and 16.64% before 1990.

The industry mix has two halves. Agencies and IT firms lead, with Advertising Services at 8.96%, IT Services and IT Consulting at 8.88% and Software Development at 5.97%. Then comes an industrial block: Construction 3.72%, Machinery Manufacturing 3.02%, Industrial Machinery Manufacturing 2.45% and Wholesale 2.25%, 11.44% together. Willmott Dixon, OTRA, MAPAL and Sioux Technologies sit in that second half.

Sales signal: the industrial half is the more interesting list. A machinery maker with 30 staff that pays for visitor identification has salespeople working inbound accounts by hand, and that is a fit for CRM, enrichment and account-based advertising offers.

Leadfeeder on the same pages

1,641 domains run Leadinfo and Leadfeeder today, 6.70% of Leadinfo's clean set, and 78.4% of the 2,094 domains ever seen with both still have both. ZoomInfo shares 173 domains, Leadsy 119 and Lead Forensics 92. None of these pairs passes our switching tests, because the sites that try two tools mostly keep two. Where Leadinfo and Leadfeeder overlap, the buyer looks to be comparing match rates rather than replacing one.

"1,641 sites pay for Leadinfo and Leadfeeder at the same time, and four in five of the sites that ever ran both still do. Neither tool is winning by replacement." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: the 1,641 dual-tag domains are the warmest list on this page for anyone selling against either vendor. They pay twice for the same job, and a consolidation pitch backed by a match-rate test is the obvious opener.

The stack around it

Google Analytics runs on 84.2% of the 24,482 clean live Leadinfo domains and WordPress on 56.36%, with Elementor on 19.97%. Webflow, at 6.01%, is a minority. CRM tags are thin on the page: Zoho 1.45%, Salesforce 1.35%, Microsoft Dynamics 0.63%. Leadinfo pushes companies into CRMs through integrations, so you can't read a site's CRM from this list.

Sales signal: Benelux WordPress agencies are the natural channel. More than half of these sites run WordPress, and Advertising Services is the largest single industry among the buyers.

What it costs

Leadinfo's pricing page (14 October 2026) lists Starter from €69 a month billed annually, for up to 50 identified companies, then Scale from €159 and Pro from €359, each priced up by identified-company volume. There's a 14-day trial with no card.

Sales signal: pricing by identified companies turns traffic growth into an upgrade conversation. A site that adds paid traffic is a natural moment for a rival's pitch.

Key takeaways

1. 24,503 live domains, 6th in Visitor Identification with 7.42%.

2. 46.26% of matched companies are Dutch, and the Netherlands and Belgium hold 59.2%.

3. 89 different account keys on 89 sampled sites: direct customers, not an agency fleet.

4. Visitor Queue on 5.22% of domains is mostly the same Leadinfo account, not a second purchase.

5. 1,641 domains run Leadfeeder too, and four in five of those pairs persist.
