Overview

RB2B identifies anonymous website visitors and can send their details to sales and marketing tools. It suits teams that want to route website activity into an existing CRM or messaging workflow, especially when identifying US visitors at the person level is useful. The free tier is a limited company-identification option; person-level details and broader integrations require a paid plan.

Key features

RB2B can return a visitor’s name, LinkedIn URL, business email, company and domain, plus firmographic details such as employee count, revenue and industry. Its company says its technology can identify up to 80% of website traffic, but person-level identification is limited to US-based visitors. Global coverage is company-level through Demandbase and requires consent capture for GDPR compliance.

Hot Leads lets teams filter visitors by revenue, company size, seniority, department, category and geography, then route matching visitors to different integrations. RB2B connects to more than 50 apps, including HubSpot, Salesforce, Slack, Teams, Clay, Zapier, Apollo and webhooks. That combination is most useful when a team already has a defined lead workflow; the free tier’s Slack-only routing is much narrower.

Setup involves adding RB2B’s pixel to the website header and connecting Slack or Teams and a CRM. The company states that it is SOC 2 Type II certified and CCPA compliant, does not resell customer data or use it to train third-party models, and is monitored around the clock with Amazon Inspector used for continuous vulnerability management. Support includes a self-serve knowledge base, AI chat, email and human escalation.

Pricing

RB2B has a free plan, paid plans from $79 per month and a 7-day trial. The free tier includes company-level identification and 150 monthly resolutions, with Slack delivery only. It excludes person-level identification and email addresses, so it works as a constrained way to identify companies rather than a full prospecting workflow.

Free — 0.00 USD per free: Basic Resolution, company-level ID, Slack delivery and 150 monthly resolutions. No person-level ID, email addresses or other integrations.
Starter — 79.00 USD per month: Basic Resolution, LinkedIn URLs to Slack and Teams, and 300 monthly resolutions. It adds person-level LinkedIn URLs but still excludes email addresses and other integrations.
Pro — 149.00 USD per month: Basic Resolution, LinkedIn URLs to Slack, business email addresses and all other integrations. This is the first plan suited to teams that need email and broader routing.
Pro+ — 199.00 USD per month: Premium Resolution, LinkedIn URLs to Slack, business email addresses and all other integrations. It fits teams that want premium rather than basic resolution; no resolution quota is stated for this plan.

Starter is the practical entry point for teams that can work from LinkedIn URLs and need Teams delivery. Pro costs more but is the plan to consider for business email and integrations beyond Slack and Teams. The 7-day trial gives a short evaluation window; the listed paid prices are monthly.

Platforms

RB2B supports web and API platforms. Its pixel-based setup connects website activity to downstream tools, while webhooks provide a route for enterprise teams that ingest the visitor feed directly.

Who it's for

RB2B is aimed at early-stage businesses, growth teams already using a CRM, and enterprise teams that consume visitor data through a webhook. Its value is strongest for teams able to act on identified company or person data quickly. It is a poor fit for teams that need person-level identification outside the US, or that need email addresses on the free or Starter plan.

Pros and cons

Pros: The free plan provides 150 monthly company resolutions, giving small teams a no-cost way to surface company activity in Slack.
Pros: Pro includes business email addresses and all other integrations, supporting a broader workflow than Slack-only delivery.
Pros: Hot Leads filters by firmographic and role criteria and routes matches to different integrations, which helps teams focus on a defined target profile.
Cons: Person-level identification is US-only, limiting its usefulness for teams prospecting internationally at the individual level.
Cons: The free tier omits person-level ID, email addresses and all integrations except Slack, so it cannot support a full lead-enrichment workflow.
Cons: Starter’s 300 monthly resolutions and lack of email addresses or other integrations may be restrictive for teams seeking more than LinkedIn URLs through Slack or Teams.

Alternatives

Visual Visitor uses custom pricing based on successful identifications, with month-to-month and annual options.

Verdict

RB2B is a strong fit for US-focused teams that want to turn anonymous website visits into filtered, routed sales signals and already work in Slack, a CRM or connected sales tools. Its free tier makes company identification accessible, while Pro unlocks email addresses and the full integration set. Look elsewhere if international person-level identification is central, or if the free or Starter limits leave too much of the workflow out.
