Full orchestration vs. person-level visitor identification.
Website visitor identification has been around for years — tools like Clearbit Reveal and Leadfeeder identify companies visiting your site. RB2B changed the game in 2024 by identifying individual visitors by name and LinkedIn profile, not just company. Warmly does the same thing and adds a full orchestration layer on top: real-time Slack alerts, HubSpot and Salesforce routing, AI-powered outreach triggers, and EU visitor support. RB2B is free, focused, and US-only. Warmly is paid, comprehensive, and built for teams that need the full system.
Person-level vs. company-level identification
Both Warmly and RB2B identify individual visitors by name and LinkedIn profile — not just the company. This is the core value proposition that separated them from older IP-matching tools. Before RB2B, most visitor ID tools could tell you that someone from Salesforce visited your pricing page. Now you can see that Michael Chen, VP of Sales at Salesforce, visited — and act on that signal specifically.
Free tier and simplicity
RB2B has a genuinely useful free tier — person-level visitor ID with LinkedIn profile matching, delivered to your Slack. For solo founders and small teams, this is immediate value with zero cost. Setup takes minutes. Warmly starts at $700/month. The jump is significant and only justified when you need CRM routing, EU support, or the full orchestration features.
Orchestration and routing
Warmly's differentiation is what happens after identification. It can automatically route a visitor to the right rep in your CRM, trigger a personalized email sequence, alert via Slack with contact enrichment data, and handle visitors from the EU (RB2B is US-only). For teams with SDRs and defined territory assignments, the routing and automation layer is where Warmly earns its cost.

The verdict
Start with RB2B — it is free, installs in minutes, and delivers person-level visitor identification immediately. For most early-stage teams, this is all you need. Upgrade to Warmly when you have SDRs who need real-time routing, when you have EU traffic you cannot ignore, or when you want to build automated outreach workflows off visitor signals. Do not pay $700+/month for Warmly before you have proven that visitor intent data actually converts for your business.
How accurate is person-level visitor identification?
Both tools match visitors to LinkedIn profiles using a combination of IP data, email matching (via ad networks and email pixels), and device fingerprinting. Accuracy varies — it is not 100%. B2B tools are generally more accurate than B2C. Expect to correctly identify 20-40% of your visitors by person, with false positives at a low rate.
Why is RB2B US-only?
GDPR restrictions make person-level tracking without explicit consent legally complex in the EU. RB2B has chosen not to operate in that environment. Warmly has built EU support with appropriate consent mechanisms. If you have meaningful EU traffic, this alone may justify the Warmly upgrade.
Can RB2B and Warmly work together?
They are direct competitors — there is no native integration. Most teams choose one. Given RB2B's free tier, the typical path is to start with RB2B, validate that visitor intent signals actually convert in your sales motion, and then evaluate whether Warmly's automation layer is worth the cost.
