RB2B Review and Alternatives: Person-Level Visitor ID

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 pricing, 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 on Starter to Slack or Teams, and on Pro and Pro+ 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.

RB2B pricing: what each plan costs

RB2B's pricing page lists four plans: Free at $0 with 150 monthly resolutions of company-level identification, Starter at $79 for 300, Pro from $149 for 600 with business emails and integrations, and Pro+ from $199 for 600 with premium resolution. Pro's menu climbs to 2,500 resolutions at $349 and Pro+ to 5,000 at $499 and far beyond. There is no annual billing switch.

How the credits work, from RB2B's own help centre:

• One credit per unique visitor per 30 days. A visitor identified in that window uses one credit however often they return, and that applies to company-level identifications as well as person-level ones, so a resolution that only names the visitor's company spends a credit too.
• Credits refresh each billing cycle and do not roll over. Every identified visitor uses a credit whether or not it fits your ICP; restricting low-intent URLs such as careers or blog pages is the lever RB2B names for saving them.
• At the cap, tracking stops. The script is disabled until you add overage credits, upgrade or wait for the reset, and visitors during the pause cannot be identified afterwards. Overages run at 45 cents per resolution on Starter and 25 cents on Pro and Pro+.
• Additional domains cost $99 a month for up to five on Pro and Pro+.
• The trial. The pricing page says to try the Pro plan free for 7 days; RB2B's support article says new accounts get a 7-day trial of Pro+ with no payment details. Either way, it is the only honest way to learn your own match rate.

The pricing page also runs a banner reading "RB2B + DEMANDBASE = 70-80% RESOLUTION", and its Pro+ menu extends to 2,500,000 monthly resolutions.

How accurate is RB2B?

RB2B publishes its coverage in two places, and they do not agree. The pricing page shows no contact-level identification on Free, 15-20% contact-level coverage on US traffic for Starter and Pro, and 35-45% on Pro+, with company-level coverage at 15-20% below Pro+. RB2B's own support article, updated this week, says Starter and Pro reach roughly 30 to 40% in total and Pro+ averages 70 to 80%.

Plan	Pricing page	Support article
Free	No contact-level ID; company-level 15-20%	Company-level only, about 15 to 20% of traffic
Starter	Contact-level (US) 15-20%	Roughly 30 to 40% in total
Pro	Contact-level (US) 15-20%	Roughly 30 to 40% in total
Pro+	Contact-level (US) 35-45%	Average 70 to 80%

Both are averages the vendor states about itself. The number that matters is the one your own trial produces on your own traffic.

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, with invented but ordinary inputs: if 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 and few credits go on company-only resolutions. The arithmetic is illustrative. 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.

Teams that route these resolved-visitor alerts into a sales engagement platform should read the Salesloft review and testing guide before trusting vendor review scores.

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, and at the cap the tracking script stops until you pay for more or the cycle resets.

The LeadIQ credit pricing breakdown shows how spending an email versus a phone number diverges sharply, tying the plan choice to CRM hygiene rather than credit volume.

No off-site intent layer. RB2B tags hot pages and hot leads on your own site (its pricing page lists Hot Pages for high-intent tagging and Hot Leads for ICP filtering, which come after a visitor has been resolved and the credit spent), and 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

Three notes on that table. Clearbit is now part of HubSpot: Clearbit's own blog says its free tools, including the Weekly Visitor Report, were sunset and that Breeze Intelligence's buyer intent feature offers the website visitor intent data those users were accustomed to, and HubSpot's knowledge base lists data enrichment on paid Starter, Professional and Enterprise subscriptions. Replacements are covered in best Clearbit alternatives. Leadfeeder serves euros here: its pricing page, which now says Dealfront is Leadfeeder, lists a free Lite plan and Discover from €79 a month billed annually. And Vector versus RB2B is a workflow question rather than a data question: Vector's page describes a platform fee plus credits for tracked accounts, site traffic, signals and actions, so if your response to an identified visitor is an ad impression, Vector's activation is what you are paying for; if it is a human reaching out, RB2B plus your own outreach is cheaper.

The vendor missing from that table is the one that publishes no figure at all, and the field of Lead Forensics alternatives sorts by which vendors print a volume band you can read before a sales call.

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 campaign that runs when a named account shows up.
