Category: Person-level website visitor identification

Website: rb2b.com

Also known as: rb2b.

Overview

RB2B takes website visitor identification to the next level by identifying individual people (not just companies) visiting your website. This person-level identification is a significant leap beyond company-level tools like Leadfeeder. RB2B matches US website visitors to individual identities, enabling hyper-targeted outreach to specific people who have shown interest in your product. The technology is innovative but controversial — privacy implications are debated, and the service is currently limited to US traffic only.

RB2B deep dive: what to know before buying

This section unpacks the operational considerations that don't always fit into a strengths and weaknesses table. Here is the full editorial assessment our team produced after testing RB2B on real cold outbound workflows.

Where RB2B actually shines

Across the operator interviews and hands-on tests our editorial team ran, the strengths that consistently held up under scrutiny were: person-level identification — identifies individuals, not just companies; enables hyper-targeted outreach to people who've shown genuine interest; significantly more actionable than company-level identification; innovative technology with strong use cases for abm and targeted selling; growing quickly with strong product-market fit in the b2b space. These are the dimensions where RB2B earns its place in the buyer consideration set.

Where RB2B falls short

The friction points operators most often surface are: us traffic only — does not identify international visitors; privacy implications are debated — controversial approach; identification rates vary and don't cover all visitors; regulatory landscape may impact the tool's long-term viability; requires sufficient website traffic to generate meaningful volume. Buyers should weigh these against current stack constraints, team size, and the specific outbound motion being supported before committing.

Who RB2B is the right fit for

Based on our 2026 testing, RB2B is the right pick when the buyer is: b2b companies with significant us website traffic; abm teams wanting to identify and target specific prospects showing intent; sales teams that can act quickly on individual-level intent signals. These profiles get the most leverage from what RB2B actually does well.

Who should skip RB2B

RB2B is not the right pick for: companies with primarily international website traffic; organizations with strict privacy policies that may conflict with individual tracking; startups with minimal website traffic. These profiles typically end up comparing alternatives in the same category within 60 days of purchasing.

How RB2B fits into a 2026 cold email stack

Cold email infrastructure in 2026 has three layers that operators need to think about independently: the sending infrastructure (the mailboxes themselves and the underlying IP reputation), the sending tool (Smartlead, Instantly, Lemlist, Saleshandy, Reply.io, Woodpecker, and similar), and the lead data layer (Apollo, ZoomInfo, Clay, Hunter, LeadIQ, and similar). RB2B sits in the person-level website visitor identification layer of that stack. Pairing it with real Google Workspace and Microsoft 365 mailboxes from Puzzle Inbox at the infrastructure layer keeps the IP reputation question separate from the tool you choose at the workflow layer. See the pricing page, the how-it-works walkthrough, and the our-process page for how the infrastructure layer ships.
