RB2B is website visitor identification software, made by RB2B, whose parent company is Retention.com. Visitor identification tries to name the anonymous people and companies that view a website, so that a sales team can contact them.
The site owner installs one script in the header of the site. RB2B matches each visitor against a publisher network using first-party and third-party cookies, device IDs and IP addresses, and uses Demandbase's reverse-IP lookup (finding the company that owns an IP address) to identify companies. It sends names, LinkedIn profiles, business emails and company data to Slack, Teams, a CRM such as HubSpot or Salesforce, Clay, or more than 50 other apps. Filters by company size, revenue, seniority and geography route the most relevant leads to different tools. Person-level identification works only for visitors in the United States, with a US-only database; company-level identification is global, and under GDPR it needs a consent tool on the site.
RB2B is a hosted service. A free plan identifies companies only; paid monthly plans add person-level identification and are priced by the number of resolutions (identified visitors) a month.
