Leadinfo Review

Leadinfo has earned a solid reputation in Europe as a B2B website visitor identification tool. Install a tracking snippet and within minutes you see which companies visit your site. For B2B teams watching 98% of website traffic leave without a trace, that is a compelling promise.

To write this Leadinfo review, we analyzed the platform extensively. It is the ideal choice if:

• You need a fast way to identify which companies visit your website

• Your target market is primarily in Europe (Benelux, DACH, Scandinavia)

• You want one tool that combines visitor identification with contact data and basic outreach

• GDPR compliance with EU-hosted data is a strict requirement

• You prefer a self-serve platform you can set up in under five minutes

However, Leadinfo might not be the best choice if:

• You need a global B2B data platform beyond website visitor identification

• You want buyer intent signals from sources other than your own website

• You require conversation intelligence, deal tracking, or CRM-grade pipeline management

• Your GTM strategy depends on AI-powered account prioritization across multiple signal types

• You need programmatic API access or data delivery at infrastructure scale

In this case, consider ZoomInfo: an AI GTM platform built on 500M contacts, 100M companies, 135M+ verified phones, and 200M+ verified emails. Its GTM Context Graph processes 1.5B+ data points daily, fusing CRM records, conversation transcripts, and behavioral signals to reveal why deals move or stall. Teams access this through GTM Workspace, GTM Studio, or APIs and MCP in any front-end. Start with ZoomInfo's free trial.

What is Leadinfo?

Leadinfo is a B2B website visitor identification platform founded in 2017 by Han Kleppe in Rotterdam, the Netherlands, built around a single idea: let businesses see which companies visit their website without requiring visitors to fill out a form.

In July 2022, team.blue (a pan-European digital services company) acquired a majority stake. Since then, Leadinfo has completed five acquisitions, including Visitor Queue in January 2026, its first transatlantic move. Today, the platform serves 8,000+ businesses across offices in Rotterdam, Ghent, and Dusseldorf.

Leadinfo Pros and Cons

Leadinfo Review: How It Works and Key Features

Visitor Identification

Leadinfo's core feature works through a lightweight JavaScript tracking code installed on your website. The code captures visitor IP addresses and matches them against a database of public company data sourced from commercial registers and public records. When a match is found, the company appears in your Leadinfo inbox immediately, with firmographic data, LinkedIn profiles, financial information, and a full page-visit history.

The platform reports a database of 220+ million companies from 195+ countries and 300+ million contacts. For teams with strict consent requirements, a cookieless tracking mode preserves identification while eliminating all cookie placement. All data is processed on AWS servers in Ireland, within EU jurisdiction. The practical ceiling: Leadinfo identifies roughly 30% of website visitors. Visitors on home networks, mobile connections, or VPNs remain anonymous.

Contacts

Once Leadinfo identifies a visiting company, the Contacts feature cross-references it against the 300+ million contact database to surface matching decision-makers by job title, seniority, or function. You see not just who to contact, but which pages their company browsed before you reach out. Leadinfo reports a 93% email-finding success rate via its LinkedIn contact lookup. Mobile phone numbers are available on the Pro tier only.

Autopilot

Autopilot runs email and LinkedIn campaigns against identified companies automatically. Step types include email sends (up to 500/day), LinkedIn connection requests, messages, profile visits, and follows. Campaigns can trigger automatically when qualifying companies visit your site. Autopilot is priced as a separate add-on from the base plan.

Leadbot and Integrations

Leadbot is a configurable on-site widget that triggers targeted messages, forms, and calls-to-action based on visitor behavior and firmographic attributes. The Business tier adds custom branding, A/B testing, and CRM integration. Leadinfo connects natively with 70+ tools: Starter includes basic CRM integrations (manual sync), Scale adds HubSpot, Dynamics, LinkedIn Ads, Google Ads, GA4, and Looker Studio, and Pro unlocks Salesforce and Marketo. No public API is available; custom workflows require Zapier or Make.

What Do Leadinfo Users Say?

On G2, Leadinfo holds a 4.3 out of 5 star rating from 800+ reviews. Consistent themes: praise for ease of setup, strong identification quality for Benelux and DACH companies, and the convenience of contacts and outreach in one platform. The most commonly noted limitation is the 30% identification ceiling, which reviewers describe as an expected constraint of IP-based matching rather than a product defect.

On Trustpilot, Leadinfo carries a 3.2 out of 5 (Average) rating. Trustpilot reviews for B2B SaaS tools often skew toward customer service experiences rather than product quality, which is worth considering when weighting this against G2's product-focused dataset. Reviewers across sources consistently flag pricing complexity and lower identification rates outside Europe for teams with global traffic.

Leadinfo Pricing

Leadinfo uses a two-axis pricing model: a flat monthly plan fee plus a usage-based tier determined by the number of unique companies identified per month.

Where Leadinfo Falls Short

Leadinfo does visitor identification well, but several limitations appear as teams scale their go-to-market operations.

First-Party Signals Only. Leadinfo captures only on-site behavior. It has no access to third-party intent data that reveals when a company is researching your category before visiting your website. ABM teams that want to prioritize accounts based on off-site research activity, job postings, funding events, or technology adoption signals will find a meaningful blind spot here.

Identification Rate Ceiling and Geographic Limits. IP-based identification captures roughly 30% of traffic. The remaining 70% (visitors on home networks, mobile connections, or VPNs) stay anonymous. Leadinfo's database strength is also concentrated in the Benelux and DACH regions; companies with significant North American or Asia-Pacific traffic will see lower identification rates. The Visitor Queue acquisition is expanding North American presence, but global coverage remains a work in progress.

No Public API. Leadinfo states no public API is available, limiting integration options to native connectors and Zapier/Make middleware. Technical teams building custom workflows or connecting to AI agents cannot access Leadinfo data programmatically.

Pricing Complexity and Feature Gating. The two-axis pricing model makes costs hard to predict before running a trial. Salesforce integration, mobile phone numbers, and unlimited automations all require the Pro tier at $388/month, before usage fees and add-ons.

Shallow Reporting and Attribution. Marketing teams that need to tie visitor identification directly to pipeline will find gaps. Multi-touch attribution and revenue attribution are underdeveloped relative to full GTM intelligence platforms.

Top Leadinfo Alternative: ZoomInfo

ZoomInfo addresses Leadinfo's limitations by operating at a different scale and scope. Where Leadinfo focuses on one signal type (website visits) in one region (Europe), ZoomInfo is an all-in-one AI GTM Platform combining broad verified B2B data, a multi-signal intelligence layer, and execution surfaces for every go-to-market team.

Data Scale

ZoomInfo's data foundation includes 500M contacts and 100M companies, 135M+ verified phone numbers, 120M direct dials, and 200M+ verified business emails, with 34M+ company profiles and 45M+ mobile numbers outside North America. Data is built through automated ML scanning of 28 million site domains daily, third-party partner data, 200,000+ contributing Lite users, and a Data Training Lab of 300+ human researchers. First-party data reaches up to 95% accuracy.

ZoomInfo holds 133 No. 1 G2 rankings and is a Gartner MQ Leader for ABM Platforms and a Forrester Wave Leader for Intent Data Providers.

Multi-Signal Intelligence

ZoomInfo's GTM Context Graph is the intelligence layer that captures not just what happened, but why. It processes 1.5B+ data points daily, fusing ZoomInfo's B2B data with CRM records, conversation intelligence from Chorus, and behavioral signals into a unified reasoning layer. Where Leadinfo shows which companies visited your site, the GTM Context Graph reveals which accounts are in-market: 210M IP-to-Org pairings, 6 trillion keyword pairings monthly, job change signals, technographic signals.

SpringDB achieved 2x-3x increases in campaign conversions and a 300% increase in database usability after adopting ZoomInfo's data platform. Smartsheet saw 84% MQL lift, 26% opportunity rate increase, and 59% win rate lift after deploying ZoomInfo's marketing intelligence.

GTM Execution and Access

ZoomInfo delivers its data and intelligence through three access lanes. GTM Workspace brings AI agents, account prioritization, and outreach to sellers. GTM Studio gives marketers and RevOps teams natural language audience building and campaign orchestration. And APIs and MCP connect ZoomInfo data into any tool, custom workflow, or AI agent. ZoomInfo is free to start with consumption credits based on usage. ZoomInfo Lite provides a permanent free tier including database access, monthly export credits, WebSights Lite, and HubSpot integration. A 7-day free trial with broader feature access is available with no credit card required.

Leadinfo or ZoomInfo: Comparison Summary

Final Verdict

The choice between Leadinfo and ZoomInfo depends on the scope of your go-to-market needs and where your target market sits.

Choose Leadinfo if: your primary goal is identifying which companies visit your website; you operate in Europe (especially Benelux or DACH); you want a GDPR-first tool with EU-hosted data and transparent pricing; and your sales cycles are straightforward.

Choose ZoomInfo if: your GTM strategy requires more than website visitor identification; you need global data coverage; you rely on multi-signal intent data to identify in-market accounts; you want conversation intelligence and AI-powered account prioritization; or you need programmatic access (APIs/MCP) to connect data across your stack.

Go beyond visitor data and run full-cycle GTM with ZoomInfo.

The difference is scope. Leadinfo answers one question well: which companies are on your site right now. ZoomInfo answers a broader set: who to target, when they are in-market, why deals advance or stall, and what to do about it.

Leadinfo FAQ

What does Leadinfo actually identify?

Leadinfo identifies companies, not individuals. It matches visitor IP addresses against a database of publicly available company data to reveal which organizations browse your website. Roughly 30% of website visitors can be identified this way. Visitors on home networks, mobile connections, or VPNs remain anonymous. The Contacts feature then surfaces decision-maker profiles at identified companies from a separate 300M+ contact database.

Is Leadinfo GDPR compliant?

Yes. Leadinfo is ISO 27001 certified, hosts all data on AWS servers in Ireland within the EU, and processes only pseudonymous IP-to-company mappings. It offers a cookieless tracking mode that eliminates all cookie placement while preserving identification, relying on Article 6(1)(f) GDPR (legitimate interest) as its legal basis.

How much does Leadinfo cost?

Leadinfo uses a two-axis pricing model. Plan tiers range from $73/month (Starter) to $388/month (Pro) on annual billing. A usage-based charge scales with companies identified monthly, starting at $73/month for 0-50 companies. Autopilot and Leadbot Business are additional paid add-ons. A 14-day free trial is available with no credit card required. See our Leadinfo pricing guide for the full breakdown.

How does Leadinfo compare to ZoomInfo for website visitor identification?

Both platforms identify companies visiting your website. Leadinfo uses IP-to-company matching with particular strength in European markets. ZoomInfo's WebSights adds buying team ID and bot traffic filtering with a larger global database. The key difference: ZoomInfo layers website visitor data with off-site intent signals, technographics, and conversation intelligence, while Leadinfo captures first-party website signals only.

Does Leadinfo have an API?

No. Leadinfo states no public API is currently available. Users are directed to Zapier or Make for custom integrations beyond the 70+ native connectors. ZoomInfo includes API access in all relevant plans and offers an MCP server for connecting AI models directly to its B2B data.

Can Leadinfo replace a full GTM intelligence platform?

Leadinfo covers a specific workflow: identifying website visitors and reaching out to them. It does not provide off-site intent signals, conversation intelligence, deal tracking, technographic data, or programmatic data access. Teams needing full GTM intelligence will likely need Leadinfo alongside several additional tools, or a broader platform like ZoomInfo. See our Leadinfo alternatives guide for other options.
