Best website visitor identification tools for B2B teams in 2026

In short: For company-level identification, start with Leadfeeder or Snitcher; choose RB2B only if many visitors are in the US, since its person-level identification is US only; use HubSpot buyer intent if you run HubSpot. Albacross, Lead Forensics and Warmly add contact data or a wider platform.

For most B2B teams, the best website visitor identification tools in 2026 are Leadfeeder or Snitcher for simple company-level identification, RB2B if many of your visitors are in the US and you want named people, and HubSpot’s buyer intent if you already run HubSpot. Albacross, Lead Forensics and Warmly suit teams that want contact data or a wider inbound platform on top of identification.

The most important question is not which tool is “best” but what it can identify for your traffic. Most tools name companies. Fewer name people, and person-level identification is often limited to US visitors, which matters if your buyers are in Singapore or the region.

How we chose

We looked for tools that identify the organisations, and in some cases the people, behind anonymous B2B website visits. We compared them on five points:

• What they identify. Company only, or company plus person.
• Geographic limits. Especially any restriction on person-level identification.
• Pricing transparency. Whether prices are published on the vendor’s own site.
• Entry point. Whether there is a free plan or a trial you can run on your own traffic.
• Privacy statements. What the vendor says about how it handles data.

Every fact below comes from the vendor’s own website, checked in October 2026. Prices change often, so check again before buying. We do not include ratings or review scores. We left out Koala, which was on our original shortlist, because its pricing page says it has been acquired by Cursor and was shutting down on 30 September.

FYAdvisers is not a visitor identification tool and is not in this list. We mention our own service only in the closing section.

Quick comparison

1. Leadfeeder

Leadfeeder reveals the B2B companies visiting your site using an IP-to-company database. The product was previously sold as Dealfront; its own site now carries the post “Dealfront is now Leadfeeder”.

Best for: teams that want to see which companies visit, at no cost to start.

Cost (October 2026): its pricing page lists a free Lite plan showing up to 100 identified companies a month with seven days of history. Paid plans start at €79 a month billed annually (€113 billed monthly), with higher plans adding verified emails and phone numbers through credits. Paid plans include a 14-day trial.

Strengths: a genuine free tier, unlimited users on the free plan, and company-level identification that does not depend on the visitor’s country.

Limits: it names companies, not the individual visitor. Contact details come from enrichment credits on higher plans.

2. RB2B

RB2B offers both company-level and person-level identification.

Best for: teams with a meaningful share of US website traffic.

Cost (October 2026): its pricing page lists a free plan with company-level identification only, and paid plans from US$79 a month that add contact-level identification. Higher plans start at US$149 and US$199 a month.

Strengths: low entry price for named-person identification, and a free company-level plan to test with.

Limits: the pricing page labels contact-level identification “US Only”, while company-level identification is global. For Singapore and regional visitors, treat it as a company-level tool.

3. Snitcher

Snitcher focuses on identifying companies, with contact details revealed only when you choose to.

Best for: small teams that want predictable monthly pricing.

Cost (October 2026): its pricing page prices plans by the number of unique companies identified a month, starting at US$49 for up to 50 companies. A 14-day free trial needs no credit card.

Strengths: clear tiered pricing published on the site. Snitcher says it is built for GDPR compliance, processes data under the legitimate interest basis, and focuses on company-level intelligence.

Limits: pricing rises with the number of companies identified, so high-traffic sites should estimate volume during the trial.

4. Albacross

Albacross shows which companies visit your website and adds verified email and phone credits.

Best for: teams that want company identification and some contact data in one subscription.

Cost (October 2026): its pricing page lists Starter from €59 a month and Professional from €149 a month, both billed yearly, with an Organisation plan by quote. There is a 14-day free trial and no free plan.

Strengths: published prices and contact credits included in each paid plan.

Limits: contact credits are capped by plan, with extra credits sold separately.

5. HubSpot buyer intent (formerly Clearbit)

Clearbit’s own site now says Clearbit has joined HubSpot, and HubSpot offers the visitor identification side as buyer intent, part of what it markets as Breeze Intelligence. HubSpot’s knowledge base says buyer intent “connects anonymous web visitors to known companies’ IP addresses” using the HubSpot tracking code.

Best for: teams already using HubSpot as their CRM.

Cost (October 2026): buyer intent is available on Starter, Professional and Enterprise subscriptions for several hubs, and tracking a company costs 10 HubSpot Credits, charged monthly while tracking continues.

Strengths: identified companies land directly in your CRM, and you can set which pages count as intent.

Limits: it works at company level. It only makes sense if HubSpot is already your system of record.

6. Lead Forensics

Lead Forensics identifies the companies behind anonymous B2B website visitors and adds decision-maker contact data.

Best for: teams that want a guided setup and unlimited users.

Cost (October 2026): its pricing page says pricing is based on your website traffic. You start with a demo and then a one-week free trial, after which the vendor recommends a package. Users are unlimited.

Strengths: unlimited logins, real-time visitor alerts, and CRM integrations including Salesforce, HubSpot and Microsoft Dynamics.

Limits: no published prices, and the trial is shorter than most in this list.

7. Warmly

Warmly identifies both contacts and companies as part of a wider platform with chat, routing and automated follow-up.

Best for: larger teams that want identification, chat and automation together.

Cost (October 2026): its pricing page lists the web de-anonymisation plan from US$10,000 a year, with chat and autopilot plans above that.

Strengths: person and company identification combined with tools to act on visits quickly.

Limits: the highest entry price here, and the pricing page does not state geographic coverage for person-level data, so ask about Singapore visitors before buying.

Singapore PDPA considerations

This is general information, not legal advice.

The line that matters is company versus person. PDPC’s Advisory Guidelines on Key Concepts in the PDPA say data is personal data if an individual can be identified from it, alone or with other information the organisation has or is likely to have access to. Business contact information is largely outside the data protection provisions, but a record of what a named person browsed is more than contact details.

In practice:

• Company-level tools (Leadfeeder, Snitcher, HubSpot buyer intent) mainly produce information about organisations.
• Person-level or contact-enriched tools (RB2B, Warmly, and the contact credits in Albacross and Lead Forensics) link people to data. Ask how it was collected and what consent it relies on.
• Outreach rules still apply. Calls and texts to Singapore numbers fall under the Do Not Call provisions unless an exclusion applies. See B2B outreach in Singapore: what PDPA and the Do Not Call rules allow.

Our pricing page visit signal explains a safer pattern: use aggregate visits to judge demand, and act on individual activity only for known contacts who have been told how their data is used.

How to choose

1. Check where your visitors are. If most are in Singapore or Asia, a US-only person-level feature adds little. Start with a company-level tool.
2. Start free or on a trial. Leadfeeder and RB2B have free plans; Snitcher, Albacross and Lead Forensics offer trials. Run two side by side on the same weeks of traffic.
3. Count useful matches, not total matches. Filter out ISPs, students, job seekers, competitors and existing customers, then see how many target accounts remain.
4. Decide who acts on the data. An alert nobody follows up is wasted. Plan how a visit becomes a reason to reach out.
5. Settle the PDPA questions first, especially for contact-level data.

Visitor identification only sees companies that already reached your website. If your best buyers rarely browse supplier sites before they are approached, a different approach may fit better. FYAdvisers runs signal-based lead generation as a done-for-you service: we watch public events such as GeBIZ awards, regulatory filings and funding news, research each account, draft outreach you approve and hand replies to your sales team. We compare the two approaches in signal-based lead generation vs website visitor identification, and you can browse the events we track in the signal library.
