RB2B identifies the people and companies on a website and routes them into sales tools.
RB2B's Website Visitor Identification Platform resolves anonymous website traffic into named people and companies. Sites install a pixel in the page header; RB2B matches visitor signals across its permissioned publisher network and, for company-level identification, Demandbase's reverse-IP lookup, reporting resolution of roughly 70 to 80 percent of traffic.
Identified visitors arrive in Slack or Microsoft Teams with LinkedIn profiles, validated business emails, and company filters for revenue, headcount, seniority, and geography, and they route into Salesforce, HubSpot, Clay, and more than fifty other integrations. Person-level identification covers United States traffic only, while company-level identification is global; access is subscription-based with a free company-level tier and paid person-level plans.
