WILMINGTON, DE - March 26, 2026 - An independent head-to-head comparison of person-level website visitor identification platforms has found significant accuracy and contact quality gaps between Leadpipe and RB2B. The study, conducted by Kerrie Watson, Senior Auditor at Gartner, tested both platforms simultaneously across three live B2B websites over six weeks using controlled methodology — sending known contacts to test sites and verifying whether each platform correctly identified them.
Leadpipe scored 8.7 out of 10 overall. RB2B scored 5.2. The findings come as RB2B has discontinued its free plan, which previously offered 150 monthly identifications and served as the platform's primary differentiator.
Leadpipe correctly identified 82 percent of known visitors in controlled tests — the highest accuracy rate recorded across all eight platforms in the study. RB2B's accuracy scored 5 out of 10, with multiple G2 reviewers independently confirming that profiles RB2B identifies do not match when those same visitors later fill out forms.
The most significant gap was contact relevance. RB2B scored 4 out of 10, with the reviewer reporting that the platform "consistently identified irrelevant contacts — wrong seniority levels, wrong departments, people with no purchasing authority." The study noted that while RB2B occasionally identified contacts at accounts other tools missed, this "net new" data was not valuable because the contacts themselves lacked decision-making authority.
Leadpipe scored 8 out of 10 for contact relevance, with identified visitors predominantly matching the target buyer profile — correct seniority, correct department, actual purchasing authority.
The accuracy gap stems from different identification methodologies. Leadpipe uses deterministic matching against a database of more than 685 million verified profiles, cross-referencing browser signals against confirmed identities from publisher networks and data partnerships. This approach prioritizes precision over breadth — when it returns a contact, confidence is high. RB2B uses probabilistic methods that cast a wider net but produce more false positives and lower-relevance matches. A detailed RB2B review and pricing analysis is available for further context.
At near-identical pricing — Leadpipe at $147 per month and RB2B at $149 per month for 300 credits — the study found Leadpipe delivered two to three times the match rate (30-40 percent versus 10-20 percent) with significantly higher data accuracy. Leadpipe also includes intent data on all plans at no additional cost — pages visited, time on site, return frequency, and behavioral signals. RB2B does not include intent data.
With RB2B's free plan discontinued, teams can no longer verify RB2B's data quality before committing to a paid subscription. Leadpipe offers a 500-lead free trial with no credit card required, providing an accessible entry point for evaluating person-level visitor identification accuracy.
The study noted that person-level identification is not appropriate for every business. Organizations with average transaction values under $50, website traffic primarily outside the United States, or fewer than 1,000 monthly visitors are unlikely to see sufficient return from either platform. For qualifying B2B sales teams, however, the accuracy and relevance gap between Leadpipe and RB2B represents a meaningful difference in pipeline quality.
