RB2B

RB2B turns website visits into company and, for US visitors, person-level records that can feed sales workflows. It is best suited to teams with a CRM or messaging destination ready to act on inbound interest. Its free plan offers a constrained way to identify companies; more useful person-level data and routing depend on paid tiers.

Overview

RB2B identifies anonymous website visitors and sends their data to a CRM, Slack, or an activation platform. The company says it can identify up to 80% of website traffic, though actual identification will depend on a site’s visitors. Person-level identification is limited to the US. Company-level identification is global through Demandbase, with consent capture required for GDPR compliance.

Key features

Identified records can include a person’s name, LinkedIn URL and business email, alongside company and domain details and firmographic data such as employee count, revenue and industry. Those fields can give sales teams more to qualify than a company name alone, but the free plan omits person-level identification and email addresses.

Hot Leads filters visitors by company revenue and size, seniority, department, category and geography, then routes matching traffic to different integrations. RB2B connects to more than 50 apps, including HubSpot, Salesforce, Slack, Teams, Clay, Zapier, Apollo and webhooks. This routing is useful when a team has established destinations and follow-up rules; it offers less to teams without a CRM or other workflow to receive the data.

Setup involves placing a pixel in the website header and connecting it to Slack or Teams and a CRM. RB2B says it is SOC 2 Type II certified and CCPA compliant, does not resell customer data or use it to train third-party models, and uses 24/7 monitoring with Amazon Inspector for continuous vulnerability management. Support includes a self-serve knowledge base, AI chat and email support, with human escalation listed across plans.

Pricing

RB2B uses a freemium model, with a 7-day trial and paid plans starting at $79 a month. The key trade-off is identity depth and routing: lower tiers cap monthly resolutions and restrict what data reaches which tools.

Free — free: Includes basic resolution, company-level identification, Slack push and 150 monthly resolutions. It excludes person-level ID, email addresses and integrations beyond Slack. This is a reasonable test of company identification, but not a fit for teams that need named contacts or CRM delivery.

Starter — $79 a month: Adds LinkedIn URLs sent to Slack and Teams, with 300 monthly resolutions. It still excludes email addresses and other integrations, so it suits teams that can work from LinkedIn records in those messaging tools rather than syncing directly to a CRM.

Pro — $149 a month: Includes business email addresses, LinkedIn URLs to Slack and all other integrations. It is the more practical tier for teams needing contact data and CRM or activation-platform routing.

Pro+ — $199 a month: Adds premium resolution to the Pro combination of LinkedIn URLs, business email addresses and integrations.

Platforms

RB2B is available on the web and via API. Its pixel-based setup makes it relevant to teams managing a website, while API access and webhooks provide routes for teams ingesting visitor data into their own systems.

Who it's for

RB2B maps to early-stage businesses seeking a basic visitor-identification workflow, growth-stage teams already using a CRM, and enterprise teams that ingest its feed by webhook. It is a stronger fit for teams with a US-heavy audience if person-level identification is central; organizations focused on visitors elsewhere should expect company-level identification instead.

Pros and cons

Pro: Useful qualification fields. Records can combine person, company and firmographic details, helping teams prioritize inbound visits.

Pro: Flexible routing for established workflows. More than 50 integrations and Hot Leads filters support directing different visitors to different destinations.

Pro: A genuinely usable free starting point. Company-level identification and 150 monthly resolutions let teams try the core approach without paying.

Con: Geography limits person-level value. Person-level identification is US-only, which narrows its usefulness for teams targeting international visitors.

Con: The free plan is tightly constrained. It has no person-level ID or email addresses and sends data only to Slack.

Con: Starter remains limited for CRM workflows. Despite its 300 monthly resolutions, it excludes email addresses and integrations beyond Slack and Teams.

Verdict

Choose RB2B if your team wants to turn website activity into actionable sales records and already has a CRM, Slack or another destination to receive them. Its strongest case is the combination of visitor details, filtering and routing; its main reasons to look elsewhere are the US-only person-level coverage and the free and Starter plans’ restrictions on identity data and integrations.
