The best B2B website visitor identification software is not the one with the biggest database or the boldest match-rate claim. It is the one that fits what you do after the match. So before the tool list, settle the two questions that actually decide your choice: do you need the person or just the company, and what happens the moment a match fires. Get those right and the shortlist narrows itself.
Here are the real tools in 2026, priced, with honest match rates, sorted by that first question.
Person-level versus company-level: the fork that decides everything
Every tool in this market sits on one side of a line. Company-level tools tell you Acme Corp visited. Person-level tools tell you Jane at Acme visited. Person-level is more actionable and much rarer, and the price and the tool both follow from which one you need.
- Person-level: RB2B and Warmly resolve to the individual, pushing LinkedIn profiles and sometimes business emails.
- Company-level: Leadfeeder, Leadinfo, Albacross, and Lead Forensics identify the visiting company, which you then work into a named contact yourself.
If you have not read how the underlying technology works and why match rates are lower than vendors claim, start with how to identify anonymous website visitors. This piece assumes that and focuses on the tools.
The tools, priced
| Tool | Level | Pricing | Match / note |
|---|---|---|---|
| RB2B | Person | $79/mo Starter, from $149/mo Pro | 15-20% contact-level on Pro, 35-45% on Pro+; pushes LinkedIn URLs, emails from $149 |
| Warmly | Person + act | from | ~15% person-level; reveal plus intent, chat, outbound in one platform |
| Leadfeeder | Company | from ~$99/mo (Discover EUR 79/mo annual), up to ~$399 | dependable company-level, strong CRM enrichment, good free tier |
| Lead Forensics | Company | custom quote, no public price | enterprise company-level, priced on how much traffic it IDs |
| 6sense / Demandbase | Company + ABM | custom quote | enterprise ABM budgets and motions |
| HubSpot Breeze | Company | native to HubSpot | the low-friction pick if you already run HubSpot |
| MarketBetter | Person + outreach | $99/user/mo flat | visitor ID plus automated outreach, aimed at SDR teams |
| Vector | Signals | varies | leans into high-intent signals over raw identification |
A few honest notes on that table. RB2B is the value pick for person-level identification in the US, and its match rate climbs meaningfully from the entry tier to Pro+. Warmly costs more because it bundles the “what next,” reveal plus intent signals plus outbound orchestration in one place, which is worth it only if you will use that whole loop. Leadfeeder has the most dependable company-level reveal and the best free tier, which makes it the sensible starting point for European or company-level needs. And the enterprise options, Lead Forensics, 6sense, and Demandbase, hide their pricing behind a quote for a reason: it scales with how much of your traffic they can identify.
Match rates: what to actually expect
Hold every vendor to the real numbers. Person-level identification reaches only 5 to 20% of US B2B traffic, which lines up with Warmly’s own reported ~15% and RB2B’s 15 to 45% across tiers. Company-level lands at roughly 30 to 65%. No single tool breaks 50% at the person level, and any vendor claiming 90% is describing a lab, not your site. The full breakdown of why is in how to identify anonymous website visitors.
This is why the tool choice matters less than people think. The gap between a good tool and a great one is a handful of percentage points of match rate. The gap between a match that gets worked and a match that sits in a dashboard is the whole ROI.
The part that decides ROI
A revealed visitor is a signal, not a sale. The software’s job ends at the match, and the return starts right after it, when the record gets enriched into a full contact, scored against your ICP, routed to a rep, and reached out to while the visit is still warm. That routing engine is the same one that handles inbound signups, and we build it in Clay enrichment and lead routing.
A website visit also becomes far more useful next to other buying signals, funding, hiring, technology changes, which is the domain of intent data platforms, and the outreach itself has to be timed to the signal, which is what AI outbound coordinates. We build these signal-to-outreach systems end to end, including an intent-monitoring build that turned marketplace signals into outbound.
The takeaway
Choose your B2B website visitor identification software in two steps. Decide whether you need person-level (RB2B, Warmly, MarketBetter) or company-level (Leadfeeder, Lead Forensics, 6sense, HubSpot Breeze), then pick the one whose price matches your volume and whose “act on it” features match what you will actually use. Expect 5 to 20% at the person level and 30 to 65% at the company level, and ignore anyone promising more. Then put your real effort into the system that works the matches, because that, not the pixel, is where the pipeline comes from. Building that end-to-end is what GTM engineering is.
