RB2B Review and Alternatives: Person-Level Visitor ID, Priced Honestly

RB2B Review and Alternatives: Person-Level Visitor ID, Priced Honestly

RB2B does one thing that most of the visitor-identification category does not: it returns the name of a person who visited your website, not just the company, and it pushes that person into Slack within minutes. That single capability explains both its adoption and its constraints, because person-level resolution is why the product is US-only in practice and why it is priced per resolution rather than per seat.

This is a review of what you actually get at each tier, where it breaks, and which alternatives fit the cases it does not.

What RB2B does

You install a script on your site. When a visitor arrives, RB2B attempts to resolve them against an identity graph and returns, at the higher tiers, a named individual with their LinkedIn profile and a business email address. Results push to Slack or Teams in near real time, and on paid tiers into your CRM and other tools.

The mechanism is a data co-op. Participating sites contribute hashed identifiers captured when users log in or submit forms; those hashes attach to a device or browser signature; when that signature reappears on your site, RB2B resolves it. Coverage is therefore a function of how much of the co-op your visitor has previously touched, which is precisely why US B2B traffic resolves well and non-US traffic largely does not. The mechanics of the wider category are covered in our website visitor identification guide.

Pricing, verified August 2026

From RB2B's pricing page. This is a credit model: one unique visitor resolved within a 30-day window consumes one credit regardless of how often they return, credits reset each billing cycle, and unused credits do not roll over.

Additional mechanics that change the real cost:

• Overages run at 45 cents per resolution on Starter and 25 cents on Pro and Pro+.
• Higher credit tiers are available within Pro and Pro+, and the effective per-credit cost falls substantially at volume, reaching roughly 10 cents per credit around the 5,000-credit tier at $499 per month.
• Additional domains cost around $99 per month for up to five.
• A 7-day full-featured trial gives access to Pro capabilities, which is the only honest way to learn your own match rate.

Vendor-published match rates: roughly 15 to 20 percent contact-level coverage on US traffic for Free, Starter, and Pro, rising to roughly 35 to 45 percent on Pro+. Company-level coverage tracks similarly.

The number that decides whether it is worth it

Do not compare monthly prices. Compare cost per usable, ICP-fit contact.

Take Pro at $149 for 600 resolutions. If 18 percent of your US traffic resolves and half of what resolves is ICP-fit, 600 credits buys you roughly 300 named ICP contacts a month at about 50 cents each, assuming your traffic volume is high enough to consume the allowance. That is inexpensive against any outbound data source. If instead your site gets 400 US B2B visits a month and a third of those are existing customers and job applicants, you are paying $149 for perhaps 40 useful names, and the arithmetic changes completely.

Run the trial and measure your own resolution rate before committing. Traffic mix, not the plan you pick, determines the return.

Honest limitations

Person-level is US-only in practice. The identity graph does not have the coverage outside the US, and GDPR plus ePrivacy make consent-free person-level de-anonymisation extremely difficult to justify in the EU and UK regardless. If your buyers are European, this product is not for you and you want a company-level tool instead.

Compliance is your exposure, not the vendor's. The active US risk in 2026 is state wiretapping and session-tracking litigation, including claims under the California Invasion of Privacy Act, alongside state privacy statutes. Get a privacy policy disclosure, a properly configured consent banner, honouring of global privacy control signals, and geographic gating reviewed by counsel before you deploy the pixel.

A resolved visitor is not a buyer. Competitors, job seekers, students, and your own contractors all resolve. Filter to ICP fit before anything reaches a human.

The Slack firehose becomes wallpaper. This is the most common failure mode by far. Route on page and fit, not on every visit, and suppress everything below threshold.

Person-level resolution is probabilistic. Shared devices and stale graph entries produce a confident, wrong name. Never reference the visit itself in outreach, both because it is creepy and because you will occasionally be wrong.

Credits expire monthly and overages are real money. A traffic spike from a launch or a press mention can burn a month's allowance in two days at 45 cents a head on Starter.

No intent layer. RB2B tells you who arrived. It does not tell you what they are researching elsewhere. That is a different purchase, and our B2B intent data guide covers whether you need it.

Alternatives

Two notes on that table. Clearbit Reveal is gone, not merely repriced: HubSpot acquired Clearbit, folded the enrichment into Breeze Intelligence, and sunset the standalone Reveal product and free tools, so the successor requires a paid HubSpot subscription and cannot be bought by non-HubSpot teams. Replacements are covered in best Clearbit alternatives. And Vector versus RB2B is a workflow question rather than a data question: if your response to an identified visitor is an ad impression, Vector's activation is worth the premium; if it is a human reaching out, RB2B plus your own sequencing is cheaper.

Who should buy RB2B

Buy it if your traffic is majority US B2B, you get at least a few thousand relevant visits a month, someone will act on an alert the same day, and you have had a compliance review.

Do not buy it if your buyers are in Europe, your traffic is under a few hundred relevant visits a month, or nobody owns the response. In the last case you are buying a notification, not a pipeline source.

Making it produce pipeline

The tool is the cheap part. The motion is what converts.

1. Score every resolution against ICP fit automatically and drop the rest before Slack sees them.
2. Weight by page. Pricing and product pages route to a human; blog and careers pages do not.
3. Respond inside 24 hours. The signal is perishable and its whole value is timing.
4. Reference the problem, never the visit.
5. Run the account across email and LinkedIn simultaneously rather than sequentially, using the patterns in the outbound sales playbook. If LinkedIn is the primary channel for that segment, the multi-sender approach in our HeyReach review is how to run it at volume.

Verdict

RB2B is the most accessible person-level visitor identification product on the market, and at $79 to $199 a month it is priced where a small team can actually test it. Its constraints are structural rather than fixable: US-only coverage, probabilistic resolution, credit expiry, and a compliance burden that sits with you. Buy it for US B2B traffic with a same-day response motion behind it. Buy a company-level tool instead if your market is European.

If the missing piece is the motion rather than the data, get a free campaign plan and we will build the sequence that fires when a named account shows up.
