In this guide we compare the seven website visitor identification tools US B2B teams shortlist most often in 2026, on what they identify, what they cost and who they suit. If you want the geography-neutral version of this list, the 10 best tools to identify website visitors covers the wider field.
What is website visitor identification software?
Website visitor identification software tells you which businesses are on your site and what they looked at, without waiting for anyone to fill in a form. Around 98% of website visitors leave without converting, so for most B2B companies the majority of demand never announces itself.
The software works by reading the network signals attached to a visit and matching them against a company database. Some tools then go a step further and try to match the visit to a named individual. That extra step is the single biggest difference between the products on this list, and it is worth understanding before you compare feature grids. IP tracking explains the underlying mechanism.
How we compared these tools
Feature lists all look the same at this price point, so we judged these seven on the six things that actually decide whether a tool earns its place in a US B2B stack:
- What it identifies. The company, the person, or both, and where that coverage stops.
- Pricing transparency. Can you see what it costs before you book a call?
- Speed to value. How long from signing up to seeing your own data.
- Contact data included. Does it tell you who to call, or do you need a second tool?
- Coverage when visitors decline cookies. Most tools lose 40 to 60 percent of visibility to consent banners, and identifying website visitors without cookies explains how that gap is closed.
- Integration breadth. Does it land in the CRM you already run?

Leadinfo is the only row with a yes in every column. That is the short version of this article.
1. Leadinfo
Leadinfo is a company-level visitor identification platform built for B2B teams that want to see the account, act on it the same day, and know what they are paying before they talk to anyone. It identifies the business behind a visit, enriches it with the contacts who matter, and pushes it into your CRM.
How Leadinfo works
Company identification. Every identified visit returns the company, its sector and size, the pages it read, how deep the session went and how often it came back, plus an ICP match score.
Contact data in the same view. Leadinfo delivers a 93% contact match on identified companies, including phone, business email and LinkedIn profiles. That is the column most of this market fails. HubSpot Buyer Intent identifies the company but does not hand you the contact, so teams pair it with a second source. With Leadinfo the rep opens one screen and knows who to call.
Cookieless by design. Leadinfo delivers 100% company identification without cookies. When a visitor declines your consent banner, the account still shows up. Every other tool on this list either relies on cookies or does not document the answer, and across most tools 40 to 60 percent of visibility disappears at the banner. Those are disproportionately your compliance-conscious enterprise accounts, which are the ones you least want to lose.
Automation. IF-THEN triggers route accounts automatically, from 3 rules on Starter up to unlimited on Pro. Add-ons cover automated email and LinkedIn outreach, a multi-channel chat widget and real-time website personalization, each from $39 per month.
Integrations. 75 native integrations including HubSpot, Salesforce, Pipedrive, Microsoft Dynamics and Zoho, plus 8,000 more through Zapier and Make. Setup takes 5 to 10 minutes across 13 or more installation methods. For comparison, Lead Forensics lists five native CRM integrations with the rest routed through Zapier.
Why it matters for US teams
Three things put Leadinfo ahead for an American buyer.
You can evaluate it today. Prices are published in dollars, the trial is 14 days, no credit card, and the clock starts when you place the code rather than when you sign up, so you get two full weeks of your own data. Four of the six alternatives here require a conversation before you see a number.
It answers the whole question. Most tools stop at “this company visited”. Leadinfo tells you which company, whether it matches your ICP, what it read, who to contact and what their email and phone number are, then fires the trigger that puts it in front of a rep. That is the difference between a report and a pipeline.
It does not break when your traffic stops being domestic. Because Leadinfo identifies the organization rather than the individual, a visit from Toronto or Rotterdam resolves exactly like a visit from Austin. Person-level tools built on US consumer data do not hold that up, and RB2B publishes the numbers to prove it.
More than 10,000 companies run Leadinfo. It holds 4.3 out of 5 on G2 with a High Performer award and a 9.2 ease-of-use score, which is the number that matters most for a tool your whole revenue team has to actually open.
Pricing
Published in full, and the pricing page switches to USD. On annual billing: Starter from $73 per month for up to 50 identified companies and $105 for 51 to 100. Scale from $172 per month for up to 250 companies, rising by volume to $583 at 5,000. Pro from $388 per month for up to 750 companies, rising to $961 at 5,000. Monthly billing runs higher: Starter from $107, Scale from $226, Pro from $507. Add-ons start at $39 per month. The full volume table is on solutions for every budget.
Best for: B2B teams of 50 to 1,000 employees that sell to companies, want to evaluate without a sales call, and want the contact data in the same place as the account.
2. RB2B
RB2B takes the person-level approach. Instead of returning a company, it returns an individual: a name, a LinkedIn profile and, on paid tiers, a business email address, pushed into Slack.
Person-level resolution. The core product. A visit becomes a named individual rather than an account.
Slack delivery. Identified people arrive in a channel. There is no account view, no ICP scoring and no session history to work from.
Tiered resolution quality. The free and lower tiers return company-level data only. Person-level resolution starts on Starter, email addresses on Pro, premium resolution on Pro+.
Why it matters for US teams
RB2B publishes its own boundaries. Contact-level resolution is listed as US only, with 35 to 45 percent coverage at higher tiers, and global company-level coverage sits at 15 to 20 percent. Read that second number carefully: outside the United States, more than four in five visits do not resolve at all.
So the fit is narrow. If every buyer you care about is American and your motion is a direct email to one person, it does the job. The moment your traffic includes Europe, Canada or APAC, most of it is invisible, and you are shopping for a second tool to cover what the first one misses.
Pricing
Free tier at $0 for 150 monthly resolutions, company-level only, Slack push. Starter $79 per month for 300 resolutions with LinkedIn URLs. Pro from $149 per month for 600 to 2,500 resolutions with business email addresses and all integrations. Pro+ from $199 per month with premium resolution.
Best for: Purely US pipelines running one-to-one outbound, where nobody needs an account view and foreign traffic does not matter.
3. Warmly
Warmly combines person-level and company-level identification with chat and AI-driven follow-up, aimed at teams that want signal and action in one system rather than a feed they work by hand.
Combined identification. Contacts and companies in a single view.
Inbound chat and AI follow-up. Higher tiers add an AI agent that engages visitors on the site and runs follow-up automatically.
Data foundation. Warmly publishes 220M or more people profiles, 40M or more company profiles and 33M or more intent signals per year.
Why it matters for US teams
Warmly bundles identification, chat and automated follow-up, so the tool acts rather than reports. That bundle is also the entry ticket: the lowest package is $10,000 a year, an order of magnitude above anything else here, and the capability you may actually want sits two tiers up at $30,000.
There is no trial and no free tier, so you commit budget and an evaluation cycle before you have seen it run on your own traffic. Coverage figures by region are not published, and neither is what happens when a visitor declines cookies.
Pricing
Published as annual packages. AI web identification at $10,000 per year, Inbound Chat at $20,000 per year, and AI Inbound Autopilot at $30,000 per year, each starting at 10,000 credits per month. Quarterly options are available. Add-on packages run at $10,000 per year. There is no free tier.
Best for: Funded US teams with five figures a year already allocated to chat and follow-up automation.
4. ZoomInfo
ZoomInfo is a full go-to-market platform where visitor identification is one module rather than the product. WebSights sits inside the marketing packages, alongside contact data, intent and account scoring.
WebSights. Company-level visitor identification, available from the Marketing Demand package upward.
Contact and company database. The reason most teams buy ZoomInfo in the first place, with a Chrome extension and mobile app.
Intent and scoring. Account Fit Score and buyer intent signals on Copilot Advanced, real-time intent and AI-generated account summaries on Copilot Enterprise.
Why it matters for US teams
If you are already buying a go-to-market platform, folding visitor identification into it means one contract instead of two. Beyond that the case is thinner. Visitor identification is not why anyone buys ZoomInfo, WebSights only appears from the Marketing Demand package upward, and no price is published at any tier, so you cannot work out what the module costs you without a sales conversation. Buying a platform to get one feature is an expensive route to a tracking code.
Pricing
Not published. Packages run across Sales (Professional, Copilot Advanced, Copilot Enterprise) and Marketing (Marketing Demand, ABM Lite, ABM Enterprise), quoted per organization. A free trial is offered on each package.
Best for: US enterprises already committing to the full platform, where the identification module rides along.
5. Lead Forensics
Lead Forensics has been in this market more than ten years and works on both sides of the Atlantic. It identifies companies by IP address using a tracking code, in the same way an analytics tool does.
Company identification by IP. A small piece of code, comparable to Google Analytics, matching business IP addresses to accounts.
Unlimited user logins. Included at every tier, so you are not rationing seats across a sales floor.
Dedicated customer success. A named CSM on every account, not just on enterprise plans.
Enterprise track record. Published customers include Kärcher, Barclays and Travelers. The company claims a 5X close rate and 80% recovery of lapsed customers.
Why it matters for US teams
The reference list is the strongest thing on offer here, and unlimited seats plus a CSM on every plan suit a large sales floor.
The rest of the comparison is harder going. There is no published price at any volume, so you cannot compare it against anything until you have taken a meeting. The trial is one week rather than fourteen days, and it is guided rather than yours to explore. Native integrations number five against 75, with the remainder pushed through Zapier, which is a connection you build and maintain yourself. And whether identification survives a declined consent banner is not documented anywhere.
Pricing
Not published. Calculated on your website traffic volume, quoted after a demo.
Best for: Large sales floors where unlimited seats and a dedicated CSM outweigh not seeing a price before the meeting.
6. Dealfront
Dealfront is the result of the 2022 to 2023 merger between Leadfeeder and Echobot. It combines visitor identification with sales intelligence, contact data and advertising in one platform.
Visitor identification plus intelligence. The Leadfeeder side identifies visitors, the Echobot side adds company intelligence.
Database. 60M companies and 400M contacts, per the company’s own figures.
AI ICP matching. Automated fit scoring and buying signals across the combined dataset.
Third-party validation. More than 830 reviews on G2.
Why it matters for US teams
Dealfront covers intelligence, contacts and advertising in one place, which matters if you need all three. If what you need is to know which companies visited, you are buying and maintaining a platform for one of its modules, with no published price to weigh that against.
One further gap is worth checking before you sign: cookieless operation is not documented, so nobody can tell you what a declined consent banner costs you in coverage. Our Leadinfo vs Leadfeeder page compares the identification side directly.
Pricing
Not published. Custom quotes only.
Best for: Teams buying the whole suite, where identification is one module among several they will actually use.
7. HubSpot Buyer Intent
HubSpot Buyer Intent is part of Breeze, HubSpot’s AI layer across the CRM. It shows which companies visited your site, inside the system your team already uses.
Native to the CRM. No separate login, no sync to maintain, and the data sits next to your deals.
Part of a wider AI layer. Breeze Assistant is free, Buyer Intent runs on HubSpot credits, and the agents are paid add-ons.
Documented gains. A HubSpot specialist partner reported 20 to 30 percent improvements in early 2026.
Why it matters for US teams
If your company is already on HubSpot, this adds visitor data without new procurement. What it does not do is finish the job: it identifies companies but supplies no contact details, so you still need a second source to work out who to call. Teams using it have also reported that deciding who to follow up on is harder than expected, because the signal arrives without enough around it to prioritize.
That is the whole argument, and it is worth weighing against a native HubSpot integration that brings the account and the contacts together in the first place. Our Leadinfo vs Breeze Intelligence page sets out where each one fits.
Pricing
Breeze Assistant is free. Buyer Intent consumes HubSpot credits, and the agents are paid add-ons on top of your existing subscription.
Best for: Teams locked into HubSpot that accept running a second tool for the contact data.
The verdict: which tool should you choose?
Leadinfo is the best website visitor identification software for most US B2B companies in 2026. Judged on the six criteria we set out at the top, it is the only tool here that clears all of them. It publishes its pricing in dollars, from $73 per month. It identifies the company and the contacts in one view with a 93% contact match. It keeps working when visitors decline cookies, which no other tool on this list documents. It connects to 75 systems natively. It installs in 5 to 10 minutes and gives you 14 days on your own data without a credit card or a sales call.
The rest of this list earns a place only under a narrow condition. Warmly if five figures a year for chat and automated follow-up is already in your budget. ZoomInfo or Dealfront only if you were buying the whole platform regardless, since neither will tell you what the identification module costs on its own. Lead Forensics if unlimited seats and a dedicated CSM outweigh not knowing the price until you have taken a meeting. HubSpot Buyer Intent if you are locked into HubSpot and accept paying for a second tool to supply the contacts it does not.
If none of those conditions describes you, the choice is the one at the top of this page.
Frequently asked questions
How does website visitor identification software actually work?
A small tracking code on your site records the network signals attached to each visit. The tool matches those signals against a company database and returns the business behind the visit, along with the pages it viewed. No form, no click required.
What is the difference between person-level and company-level identification?
Person-level tools try to name the individual visitor. Company-level tools name the organization and leave the choice of contact to you. Person-level gets you to an email faster inside the US. Company-level works consistently across markets and suits a buying committee, where four people from one account visiting over two weeks is a single opportunity rather than four leads.
Does visitor identification collect personal data?
It depends on the model. Person-level identification resolves data to a named individual by design. Company-level identification returns business data about an organization. That distinction matters for any European visitors you have, and does company data fall under GDPR sets out the reasoning. Leadinfo runs on ISO 27001 certification, GDPR by design and EU-only hosting.
What is the cheapest way to start?
RB2B has a free tier at 150 monthly resolutions, company-level only. For a tool you can actually run a sales motion on, Leadinfo starts at $73 per month on annual billing with a 14-day trial that needs no credit card. Everything else on this list either starts in the thousands or will not quote you without a call.
Can I connect it to my CRM?
Yes, and you should. The value is in the handoff, not the dashboard. Leadinfo offers 75 native integrations including HubSpot, Salesforce, Pipedrive, Microsoft Dynamics and Zoho, with 8,000 more through Zapier and Make. Most tools on this list cover the major CRMs; check yours before you commit.
