Companies Using Leadfeeder

We detect Leadfeeder on 36,312 domains, including Accenture PLC, Vodafone, Unilever PLC. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is IT Services and IT Consulting (11.56%).

We detect 36,312 domains running Leadfeeder across our monthly crawl of live business domains. Company data could be matched for 29,097 of them (80.1%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 5,210 domains carried a Leadfeeder detection previously and no longer do.

Leadfeeder holds 12.57% of the Visitor Identification category, ranking #3. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to Leadfeeder include FingerprintJS (25.81% market share), ipapi.co (14.42% market share), ip-api (10.27% market share), Zoominfo (10.13% market share) — measured as a share of the domains we detect running a platform in this category.

The United States at 8,581 of the companies we can place, then the United Kingdom (3,250), Germany (1,735), the Netherlands (1,715) and Finland at 1,405. Finland in fifth from a population of about 5.5 million is the strongest home-market concentration in this category, and Leadfeeder was founded in Helsinki.

The most common company size is 11-50 employees, representing 37.96% of the Leadfeeder domains we could match to a company record and size — a subset of 29,097 matched companies, not of all 36,312 detected domains. This is followed by 1-10 employees (34.24%) and 51-200 employees (18.01%).

Among the Leadfeeder domains we could match to a company with a known founding date, most were founded in the 2020s (15.64%), followed by the 2010s (39.61%). That matched subset is drawn from 29,097 companies and is not representative of all 36,312 detected domains. This suggests Leadfeeder is most popular among relatively young companies.

The ideal Leadfeeder customer is: Company Size: 11-50 employees, Industry: B2B software and agencies, Location: US, UK, Germany or the Nordics, Founded: 2000-2019, Stack: LinkedIn Insight Tag and a CRM — based on our analysis of 29,097 enriched companies at TechnologyChecker.io.

We detect Leadfeeder on 36,312 active domains as of our August 2026 crawl, third in the Visitor Identification category at 12.57%. We match it on its tracker script from leadfeeder.com or sc.lfeeder.com, its ldfdr.getTracker global, or a content-security-policy header naming the domain.

Dealfront Group GmbH. Leadfeeder, founded in Helsinki, merged with the German data company Echobot in 2022 in a deal backed by a €180m investment from Great Hill Partners. The combined business launched as Dealfront in April 2023 and has since folded that brand back into the Leadfeeder name, which is why the site reads "Dealfront is now Leadfeeder".

It reverse-resolves the IP address of a website visitor to a company and reports which pages that company looked at, so a sales team can follow up. That is different from the IP geolocation tools in the same category, which return a location and nothing about identity, and different again from device fingerprinting, which identifies a browser rather than an organisation.

There is a free tier with a 7-day lead history and no integrations, and a 14-day trial on the paid plans. The free tier is deliberately narrow, and the company-size data shows it: 11 to 50 employees is the largest band at 37.96%, the only technology in this category not dominated by companies under 10. A tool that feeds a sales team needs a sales team.

B2B services, heavily. IT Services and IT Consulting at 11.56% and Software Development at 11.11%, then Advertising Services (7.57%) and Business Consulting (4.46%) — close to a third of the base. Compare the IP-lookup tools in the same category, where no industry clears 7%: this column is telling you who buys the product rather than which platform bundled it.

By footprint in our data: Leadfeeder 36,312 domains, Zoominfo 29,253, Leadinfo 23,134, Lead Forensics 4,679. One caution on Zoominfo: it added roughly 20,000 domains over a quarter on a base of 29,000, which is the signature of a second detection clause starting to match rather than a quarter of genuine growth, so do not read its trend as momentum.

Not to a rival. Of the 4,534 domains that dropped Leadfeeder entirely, 80 now run Leadinfo (1.76%, against a 4.29% rate among domains that kept Leadfeeder), 74 run Zoominfo (1.63% against 4.71%) and 40 run ip-api (0.88% against 2.15%). Every destination is well below its base rate, so a leaver is less likely to be on a competitor than a stayer. They stop, they do not switch.

A B2B marketing stack. Google Tag Manager on 88.82% and Google Analytics on 85.59% (the highest analytics coverage in this category), then WordPress 49.02%, LinkedIn Insight Tag 41.49%, Microsoft 365 36.24%, Facebook Pixel 30.49%, HubSpot 26.12% and Google Workspace 24.96%. The LinkedIn Insight share says these companies are already running account-based advertising.

Much stickier than the rest of this category. 5,210 domains have dropped it since March 2026, about 14% of the active base, against 32% for ipapi.co and 36% for ip-api. A paid tool wired into a sales workflow does not come off as easily as a free API call.
