RB2B Review: The Person-Level Visitor ID Tool That Finally Made Our Slack Channel Worth Reading

What it’s actually good at

The pixel and the Slack channel are the whole product, and both do exactly what they say. Setup takes approximately 5 minutes: install a lightweight JavaScript pixel on your website, connect your Slack workspace, and RB2B immediately begins pushing identified visitor profiles, name, job title, company, LinkedIn URL, pages visited, time on site, directly into a dedicated Slack channel in real time.

That sounds like a small design choice. It isn’t. It’s the difference between a dashboard your team ignores and a channel your SDRs actually watch.

The mechanics under the hood are straightforward. Once you install the script in the header of your site, RB2B identifies visitors to your website who are known and have been previously identified through its expansive, fully-permissioned publisher network, using a combination of 1st and 3rd party cookies, device IDs, and IP addresses to track and identify people across the network.

When a visitor is successfully identified, RB2B enhances that record using verified professional data sources, including LinkedIn and other publicly available professional databases before it hits your channel, so you’re not looking at a raw session. You’re looking at a person you can actually pitch.

The person-level angle is the whole reason to pick this over cheaper company-level tools. The ability to match a website session to a specific LinkedIn profile and fire that information to Slack in real time was a new capability in this market, and RB2B is still the cleanest execution of it.

The free tier is still worth setting up even now that it’s masked. RB2B Free is a lightweight, introductory plan that provides basic company-level visibility into a limited number of website visitors, with up to 150 credits per month and no access to contact-level data. It’s designed to give teams a simple preview of who’s visiting their site, while reserving detailed profiles, integrations, and advanced insights for paid plans. Run it for a week on your real traffic and you’ll know whether the paid tier math works before you swipe a card. Better still, RB2B gives you a 7 day full-featured trial with LinkedIn profiles, companies, all integrations, and validated business emails , and that’s the version to actually evaluate against, because it’s what a paid seat looks like.

Where it lets you down

The January 2026 change to the free plan is the first rough edge, and pretending otherwise would waste your time. On January 22nd, 2026 the Free plan will no longer offers unmasked contact-level (person-level) resolution. RB2B will still resolve individual visitors but they’ll appear as a company-level visitor. To unmask that information users must upgrade to a paid tier. RB2B’s own reasoning is honest: person-level identity is the most resource-intensive part of RB2B to deliver, both in terms of data costs and infrastructure. When it was fully available on the Free plan, it removed the incentive to ever move into a paid tier, which limited our ability to sustainably invest in and improve the product . But if you signed up in 2024 for a free person-level pipeline, that’s gone.

The match-rate ceiling is the second thing to eyeball before you buy. Per RB2B’s own docs, contact-level coverage on Starter and Pro runs roughly 30–40% of traffic overall, and person-level identification specifically is a subset of that on US traffic. Do the math on your own site. If you’re pulling 2,000 US visitors a month, expect a few hundred named humans in Slack, not 2,000. That’s still valuable, but it’s not “every visitor, named.” Set expectations accordingly.

The US-only ceiling is a design choice, not an oversight. Sort of. RB2B’s Person-Level Identity is a US-only technology with a US-only database. If you’re looking to identify overseas individuals, our person-level tech won’t work. Why? GDPR & CCPA compliance. However, our Company-Level ID (through our partnership with Demandbase), IS global. We can help you identify companies from any country that visit your site, just not the specific individuals. If half your pipeline is European, half your Slack channel is going to say “a company from Munich visited” and nothing more.

The biggest structural gap is that RB2B is a signal, not a pipeline. Knowing who visited your site creates a list of high-intent prospects. Acting on that list requires outreach: LinkedIn connection requests, email sequences, or calls. RB2B doesn’t automate any of that. That’s why most teams end up pairing it with a LinkedIn outreach workflow, a sequencer, or something like Apollo on the email side. If you don’t have that layer, the alerts pile up unanswered, which is exactly the failure mode RB2B is supposed to solve.

What you actually pay

Prices are published, which is a rarity in this category. Here’s what shipped as of writing.

The Free plan is $0/month and gets you company-level ID with push-to-Slack and 150 monthly resolutions, no person-level names or emails. Starter is $79/mo · Basic Resolution Push Linkedin URLs to Slack Push Linkedin URLs to Teams No Email Addresses No Other Integrations · 300 Monthly Resolutions . Pro is $149/mo · Basic Resolution ‍Push LinkedIn URLs to Slack Business Email Addresses All Other Integrations · 600 Monthly Resolutions with 1,250- and 2,500-resolution bundles available at higher prices. Pro+ is $199/mo and steps you up to premium resolution: Pro+ upgrades you to Premium Resolution, which adds a waterfall of trusted external data sources to significantly expand both U.S. match rates.

The credit system is straightforward, at least. Each successfully identified visitor consumes one RB2B credit, and each credit covers that visitor’s unique activity for a 30-day rolling window, with 12 credits per visitor per year included so repeat visits within that period don’t cost extra. Build your ICP filters tight and you don’t burn credits on the wrong companies. Left loose, they evaporate fast.

The plan-picking rule is simple. Choose the Starter Plan if: Company-level identification and notifications via Slack or Teams are sufficient for your requirements. You don’t need email addresses for identified individuals. Choose the Pro Plan if: You require person-level identification to identify specific individuals interacting with your business. Translation: if you want the reason you bought this thing, you’re on Pro.

Who should actually buy it

This is where the honesty matters. RB2B is a specialty tool that earns its price on a specific setup: B2B companies with meaningful US-based inbound traffic whose buyers are active on LinkedIn and who have a sales team capable of acting on real-time intent signals. If that’s you (a founder-led team or a 5-30 person B2B shop with steady inbound and reps who can actually reply in-hour), the Pro plan pays for itself the first month you close one of the visitors it names.

If you’re selling into industries where LinkedIn adoption is thin, be honest with yourself. Match quality is high, but the addressable universe is only as wide as the pool of buyers who keep active, current LinkedIn profiles that RB2B’s identity graph can match cleanly.

The workflow you build around it’s what determines the ROI. RB2B recommends a light three-step play:

1. Connect on LinkedIn (90% accept rate) 2. Send Simple Email Flow (through Hubspot, Apollo, etc) 3. Follow up with LinkedIn message (manual, or HeyReach) For companies with higher traffic, many use Clay.com to enrich, segment, and push to messaging platforms. That’s a reasonable starter cadence, but the tool is fuel, not an engine. You still need a real follow-up sequence and outreach workflow sitting under the alerts, or a real outbound agent picking up the signal. Without that, you’ll have the world’s best-informed Slack channel and no meetings on the calendar.

The bottom line

RB2B is the tool every other person-level visitor-ID pitch is now measured against, and it earned that spot honestly. The pixel is live in five minutes, the Slack alerts are the rare kind reps actually read, and the person-level identification does something no company-level tool can match. The January 2026 free-plan change stings if you were riding the old freemium, and the fact that it hands you the lead and walks away is a real limitation for teams without an outreach layer already in place. But at $149/month for Pro, it’s the cheapest way to see the actual human on your pricing page in real time, and that’s a signal worth paying for. It’s an 87: a strong buy for the right team, one gap short of the Editors’ Choice.
