RB2B Review: Complete Breakdown [2026]

RB2B made a name for itself by doing something most B2B tools could not: identifying the actual people visiting your website, not just the companies they work for. Launched on March 1, 2024, it grew to nearly $5M ARR in under a year, with over 100,000 websites installing its tracking pixel. The appeal is clear. Instead of seeing "someone from Acme Corp visited your pricing page," you get a name, a LinkedIn profile, and a job title.

RB2B is the right choice for U.S.-focused teams that need fast, person-level website visitor identification with minimal setup. It is not the right fit if your GTM strategy extends beyond reacting to inbound website traffic.

This review is for you if:

• You need person-level identification of U.S. website visitors

• You want a quick-to-install tool that pushes leads directly to Slack

• You prioritize simplicity and speed over depth of data

• Your sales motion centers on acting fast when prospects visit your site

• You are comfortable with 15-45% visitor identification coverage

RB2B might not be the best choice if:

• You need contact data beyond website visitors

• You require global person-level identification, not just U.S. coverage

• You want buyer intent signals from across the web, not just your own site

• You need to map full buying committees, not individual visitors

• Your GTM strategy requires prospecting, outreach, and analytics in one platform

In that case, consider ZoomInfo: an all-in-one AI GTM Platform that combines a verified B2B data platform (500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails) with website visitor identification, buyer intent signals, conversation intelligence, and GTM Workspace AI-drafted outreach for sales execution. Where RB2B tells you who visited your site, ZoomInfo tells you who to call, when to call them, and what to say, across your entire addressable market.

We have included a detailed look at ZoomInfo at the end of this review. If you are ready to explore a full GTM intelligence platform, you can start with ZoomInfo's free plan here.

What is RB2B?

RB2B is a website visitor identification platform founded in 2023 by Adam Robinson, CEO of Retention.com, and launched publicly on March 1, 2024. Robinson previously built Retention.com to help e-commerce stores identify anonymous visitors for email marketing. RB2B applies the same identity resolution concept to B2B sales.

The platform works through a tracking pixel on your website. When a U.S.-based visitor lands on your site, RB2B tries to match them to an individual, delivering their LinkedIn profile, job title, and contact information to your sales team via Slack, CRM integrations, or webhooks. In early 2025, RB2B announced a partnership with Demandbase to add company-level identification globally, expanding beyond its U.S.-only person-level database. This partnership lets customers identify 70-80% of total website traffic: 30-40% at the person level (U.S. only) and another 30-40% at the company level (worldwide).

RB2B Pros and Cons

On G2, RB2B holds 4.5 out of 5 stars from 283 reviews, with users consistently praising easy setup, real-time Slack alerts, and quick identification of U.S.-based website visitors.

What RB2B Users Say

On G2, RB2B holds 4.5 out of 5 stars from 283 reviews (as of 2026). Users highlight three consistent themes: (1) easy five-minute setup that gets Slack alerts flowing the same day, (2) real-time visitor notifications that help reps act on high-intent signals immediately, and (3) the value of the Free plan for getting started without budget approval. Common criticisms center on limited match rates on standard plans, U.S.-only person-level coverage, and the January 2026 plan change that removed contact-level data from the free tier. Source: G2.

How RB2B Works and Key Features

Person-Level Visitor Identification

RB2B's core function is turning anonymous website traffic into named individuals. After installing a tracking pixel (supported on WordPress, Google Tag Manager, Wix, Webflow, and other platforms), the platform tries to match each visitor to a real person using its proprietary U.S. database.

Each identified visitor record includes their name, LinkedIn URL, job title, company name, and (on Pro plans) business email address. The platform uses a credit-based system where each unique visitor identified within a 30-day period consumes one credit, regardless of how many times they return during that cycle.

Match rates vary by plan. Starter and Pro plans deliver 15-20% person-level coverage, while Pro+ reaches 35-45% coverage through a premium resolution layer that adds external data sources. One important limitation: person-level identification is restricted to U.S.-based visitors. International traffic can only be resolved at the company level through the Demandbase integration.

Hot Pages and Hot Leads

Hot Pages lets you mark specific URLs as high-intent pages (pricing, case studies, product demos) so the platform automatically tags visitors who view that content. Tagged visitors appear under the Profiles tab; tagging is forward-looking and requires a Pro subscription.

Hot Leads automatically tags visitors matching your ICP definition across six categories: Company Revenue, Company Size, Seniority, Department, Industry, and U.S. States. Hot Lead tags can be applied to integrations to filter which visitors get pushed to Slack or your CRM, cutting noise from irrelevant traffic.

Integrations

RB2B offers 50+ native integrations spanning CRMs (HubSpot and Salesforce), automation platforms (Apollo, Clay, n8n, Smartlead, and Zapier), messaging tools (Slack and Microsoft Teams), and 22 webhook-based integrations for custom workflows. Integration access varies by plan: the free plan is limited to Slack only, and full CRM integration with email addresses requires the Pro plan at $149/month or above.

Where RB2B Falls Short

RB2B does one thing and does it quickly. But that narrow focus creates real friction for sales teams as their GTM strategy grows more sophisticated. The challenges below are not edge cases; they reflect the structural trade-offs of a point solution built for speed over breadth.

U.S.-Only Person-Level Data. RB2B's individual identification works exclusively for U.S.-based visitors. Companies targeting European markets receive company-level data only through the Demandbase partnership, and implementers must use a consent-management tool when deploying globally due to GDPR requirements. For organizations with significant non-U.S. traffic, this means a materially incomplete picture.

Limited Match Rates. Even on the Pro+ plan, 35-45% of visitors are identified at the person level. Standard Pro and Starter plans cover just 15-20%. Most of your website traffic remains anonymous regardless of plan. (Source: rb2b.com/pricing)

No Outbound Prospecting Database. RB2B only identifies people who visit your website. It offers no way to search for prospects who have not visited yet. If a target account has never landed on your site, RB2B has nothing to offer. Sales teams building outbound lists or identifying decision-makers proactively need a separate tool.

No Intent Signals Beyond Your Site. RB2B tracks what visitors do on your pages but has no visibility into what prospects research elsewhere on the web. It cannot tell you which companies are searching for your product category, reading competitor reviews, or showing buying signals on third-party sites.

Overage Costs on High-Traffic Sites. Sites with heavy traffic can burn through credits fast. Overage charges of 25-45 cents per resolution add up, and credits do not roll over between billing cycles.

Top RB2B Alternative: ZoomInfo

ZoomInfo is an all-in-one AI GTM Platform built on three pillars: a verified B2B data platform covering 500M contacts and 100M companies, the GTM Context Graph that processes 1.5B+ data points daily to reveal not just what happened but why, and Universal Access through GTM Workspace for sellers, GTM Studio for marketers and RevOps, and APIs and MCP for custom AI workflows.

This breadth addresses the core limitation of point solutions like RB2B: instead of reacting only to visitors who find your site, your team can identify in-market accounts, reach verified decision-makers, and execute across the full buyer journey.

Comprehensive B2B Data: ZoomInfo provides a verified contact and company database with global reach.

ZoomInfo's data platform spans 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct dials, and 200M+ verified business email addresses, with global coverage including 34M+ company profiles and 200M+ professional profiles outside North America.

This data is verified through a combination of automated ML scanning of 28 million site domains daily, third-party partner data covering 95 million businesses, and an in-house Data Training Lab of 300+ human researchers, reaching up to 95% accuracy on first-party data. A Fortune 500 competitive RFP analyzing 25 million contacts across vendors concluded that "no other competitor came even close." (Source: ZoomInfo Q4 2025 Earnings Call Transcript)

"ZoomInfo gives us the information we need to execute. We do not have to go through and spend our time digging. It is already there, so we can be three steps ahead." (Vensure)

Website Visitor Tracking and Buyer Intent: ZoomInfo identifies website visitors and tracks buying signals across the web.

ZoomInfo includes its own website visitor identification (WebSights), which resolves anonymous traffic to companies and surfaces buying team contacts with direct contact information. ZoomInfo goes further with Buyer Intent data, tracking signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly. This reveals which companies are researching topics relevant to your product across the web, not just on your site.

The result: you are not limited to the fraction of your market that visits your website. You can spot demand signals across the web and act on them with verified contact data attached.

"That combination of our internal CRM data, external signals, and AI that has given all that context has helped us craft very specific account- and persona-based messages. And people have responded to them right away." (Seismic)

GTM Context Graph: ZoomInfo fuses your CRM, conversation, and behavioral data into a single intelligence layer.

The GTM Context Graph is what separates ZoomInfo from data providers and point solutions. It processes 1.5B+ data points daily, combining ZoomInfo's B2B data with a customer's CRM records, conversation transcripts, email interactions, and behavioral signals into one layer.

The practical result: AI that understands why a deal is moving or stalling, not just what happened. A CRM records that a deal moved to Stage 4. Conversation intelligence captures that the CFO joined the last call and asked about six-month ROI. Intent data shows the company researching a competitor. The GTM Context Graph connects these signals to surface the right action.

RB2B tells you someone visited your pricing page. ZoomInfo tells you the CFO visited your pricing page, the company is also researching two competitors, they just hired three new VPs, and this signal combination matches 73% of your closed-won deals.

"It is not just the data itself. It is more about the right data at the right time to help us reach out with the right message across that full buyer journey." (Redwood Logistics)

GTM Workspace and GTM Studio: ZoomInfo delivers intelligence through dedicated interfaces for sellers and marketers.

GTM Workspace is the seller's interface, combining prioritized accounts, AI-drafted outreach, and deal execution in one place. GTM Studio serves marketers, RevOps, and GTM engineers with an orchestration canvas where teams describe audiences in natural language and launch multi-channel plays without engineering tickets. Expansion plays that used to take 3 weeks now launch in 30 minutes. For teams building custom workflows, APIs and MCP deliver the same intelligence into any third-party tool or AI agent.

Pricing: ZoomInfo is free to start with consumption credits based on usage. ZoomInfo Lite is a permanent free plan that includes access to ZoomInfo's B2B data platform with 10 monthly export credits, contact and company searches, a Chrome extension, WebSights Lite (up to 10 website visitor reveals per day), and HubSpot integration. A separate 7-day free trial provides broader access.

RB2B FAQ

Is there a free version of RB2B?

Yes. RB2B offers a free plan with 150 monthly resolutions and a 7-day Pro trial with no credit card required. Since January 2026, the free plan provides company-level identification only, with no access to individual contact names, email addresses, LinkedIn URLs, job titles, or page view history.

ZoomInfo offers ZoomInfo Lite, a permanent free plan with access to its B2B data platform, 10 monthly export credits, a Chrome extension, and WebSights Lite for website visitor identification (up to 10 reveals per day).

Does RB2B work outside the United States?

RB2B's person-level identification is limited to U.S.-based visitors by design. The platform uses IP geofencing to restrict person-level resolution to U.S. traffic. International traffic can only be resolved at the company level through the Demandbase partnership, and implementers targeting European audiences must use a consent-management tool to meet GDPR requirements. For teams with significant non-U.S. traffic, RB2B's person-level capabilities will not apply to most of their visitor base. Source: rb2b.com/rb2b-demandbase.

What is RB2B's G2 rating?

RB2B holds 4.5 out of 5 stars from 283 reviews on G2 as of 2026. Users consistently praise easy setup, real-time Slack alerts, and the value of the Free plan for getting started. Common criticisms include the limited match rate on standard plans, U.S.-only person-level coverage, and the January 2026 update that removed contact-level data from the free tier.

How does RB2B compare to ZoomInfo for website visitor tracking?

RB2B delivers person-level identification of U.S. website visitors at a 15-45% match rate depending on plan. ZoomInfo's WebSights resolves anonymous traffic to companies and surfaces buying team contacts with direct contact information globally. ZoomInfo adds off-site Buyer Intent data tracking signals from 210 million IP-to-Organization pairings, so you can identify in-market accounts before they visit your site. The core distinction: RB2B tells you who visited your site; ZoomInfo tells you who to proactively target across your entire addressable market. For a head-to-head competitive comparison, see RB2B vs. Warmly.

Does RB2B integrate with Salesforce and HubSpot?

Yes. Both Salesforce and HubSpot integrations are available on Pro plans ($149/month) and above. The free plan is limited to Slack only. The Starter plan ($79/month) adds LinkedIn URL pushes to Slack but does not include CRM integrations or business email addresses. Full integration access, including webhooks, Zapier, Clay, n8n, and CSV export, requires the Pro or Pro+ plan. Source: rb2b.com/pricing.
