What website visitor identification is, and why it just became urgent
Website visitor identification (or «de-anonymization») is the technology that turns an anonymous visit to your site into a real name, job title, and email — without that person filling out a form. It cross-references the visitor’s IP and cookies against company and contact databases, and today it’s the difference between chasing cold leads and reaching out to someone who was just looking at your pricing page.
The topic exploded when HubSpot announced it was acquiring Warmly, a startup specialized in identifying visitors at the person level (not just the company level) and activating them with AI agents. If your B2B SMB in Chile or Brazil depends on organic traffic or ads to generate leads, this affects you directly: up to 98% of visitors to a B2B site never fill out a form, and this technology exists precisely to recover them.
The deal driving the trend: HubSpot acquires Warmly
HubSpot confirmed the Warmly acquisition in late June 2026, without disclosing terms. Warmly identifies more than half of anonymous visitors at the individual level (name, work email, job title, and LinkedIn profile) and activates them with two AI agents: one that turns buying signals into conversations and booked meetings, and another that flags likely buyers before they even visit your site. HubSpot plans to fold this directly into its CRM, which means visitor identification is moving from a niche tool to a standard feature of the B2B marketing stack.
Company-level vs. person-level identification
Before picking a tool, it helps to understand there are two distinct approaches:
- Company-level (reverse IP lookup): identifies which company visited your site by matching the IP against corporate databases. It’s cheaper and safer from a privacy standpoint, but it won’t give you a contact’s name.
- Person-level: combines IP, third-party cookies, and data enrichment to deliver the individual visitor’s name, title, email, and LinkedIn. It’s far more powerful for direct prospecting, but it demands more legal care, especially with European traffic.
6 tools to identify visitors on your B2B website in 2026
These are the options most used by B2B SMBs this year, based on accuracy benchmarks published by RevOps consultancies:
- Warmly: person-level identification with built-in AI chat and outbound agents. The most complete option after the HubSpot acquisition; ideal if you already run that CRM.
- RB2B: matches visitors against LinkedIn profiles to deliver name, title, and verified email. Strong on US traffic, more limited in Latin America.
- Clearbit (now Breeze Intent, by HubSpot): company-level identification with native enrichment if you already operate inside the HubSpot ecosystem.
- Leadfeeder (Dealfront): specialized in European data and regulatory compliance, a good fit if you sell to EU-based clients.
- 6sense: combines visitor identification with buying-intent data from across the web, built for teams with longer, more complex sales cycles.
- Koala: geared toward product-led growth (PLG) companies, connecting on-site behavior with actual product usage.
Most offer an entry plan under $200/month, enough for an SMB getting 1,000 to 5,000 monthly visits. The most common mistake is buying the tool and never wiring it into a process: if you already have or are building an all-in-one HubSpot setup, visitor identification pays off three times over because leads drop straight into a pipeline with automatic follow-up.
Privacy and compliance: what to check in Chile and Brazil
Identifying visitors through IP and cookies isn’t the same as spying: most of these tools rely on commercially sourced (B2B) data that is already public or comes from third parties with aggregated consent. Even so, your SMB needs to disclose the use of these technologies in its privacy policy and cookie banner. In Brazil, the LGPD requires an explicit legal basis to process identifiable personal data, and Chile’s new Personal Data Protection Law follows similar logic. If you already updated your consent flow after Meta’s recent changes, review what to do about the end of the off-platform data opt-out: the same consent basis usually covers visitor identification too.
How to start this week
You don’t need to switch your stack to try this. Follow this order:
- Install the pixel from a tool with a free trial (Warmly and Koala offer one) on your pricing page and blog.
- Filter for real intent: discard visits under 10 seconds and prioritize whoever viewed pricing, case studies, or the contact page.
- Connect the signal to your CRM so the sales rep gets an alert with the visitor’s name and title, not just the company logo.
- Optimize the destination: identifying traffic is pointless if your page doesn’t convert. Review the structure of landing pages that convert at 15% so that identified visitor has a clear reason to respond.
HubSpot’s purchase of Warmly confirms something we’ve been flagging at Boostify: B2B marketing in 2026 is no longer just about attracting traffic — it’s about knowing exactly who showed up and acting before your competitor does. SMBs that put this identification layer in place now gain an edge over the ones still waiting for the form to fill itself out.
