RB2B Review (2026)
Person-level visitor identification for US traffic that publishes its own match rate and a 25-cent per-resolution meter.
RB2B in Depth
RB2B publishes its match rate. Fifteen to twenty percent on basic resolution, thirty-five to forty-five on premium.
Nobody else in this category does. Warmly, reviewed on this site the same week, claims more than half of the visitors who never fill in a form and publishes no coverage figure anywhere. It also ranks fourth for RB2B's own pricing query, which is worth holding onto: the ten-thousand-dollar vendor writes the pricing guide for the cheap one.
A coverage range that opens at fifteen percent is not a flattering number. It is a usable one, and the difference between a purchase you can model and a pilot you have to run to find out what you bought.
The plans, and the unit underneath them
Read off the vendor's page on 2026-08-05:
| Plan | Per month | Resolutions | What it gives you |
|---|---|---|---|
| Free | $0 | 150 | Company-level only, global, pushed to Slack |
| Starter | $79 | 300 | Person-level, LinkedIn URLs to Slack or Teams, no emails |
| Pro | from $149 | 600+ | Business email addresses and all integrations |
| Pro+ | from $199 | 600+ | Premium resolution, 35–45% coverage |
Overages are published as well: 25 cents a resolution on Pro and Pro+, 45 cents on Starter. Extra domains are $99 a month for up to five. Every plan carries a seven-day full-featured trial.
Now divide. $149 across 600 resolutions is 24.8 cents each, and the published overage is 25 cents. The plan rate and the meter agree to within two-tenths of a cent, which is rare enough to say out loud: this vendor charges the same whether you buy the allowance up front or run past it.
Starter does not agree with itself the same way. $79 across 300 resolutions is 26.3 cents, and its overage is 45 cents. Exceeding the allowance on the cheapest paid plan costs seventy percent more per resolution than staying inside it, which is a plan built to move you up rather than to be lived in.
What US-only actually means here
Contact-level identification is US only, stated plainly rather than buried. Company-level identification works globally, at the same fifteen to twenty percent.
That is a structural limit rather than a missing feature, and it is the mirror image of the Cognism situation on the data side. Resolving an individual person browsing a website is exactly the processing European law asks the hardest questions about, and a vendor confining it to one jurisdiction is telling you where it thinks the line sits. If your buyers are in Europe, the person-level product is not available to you and the company-level one is the whole purchase.
Against Warmly, at a fifth of the price
Warmly's published floor is $10,000 a year, or $833 a month, metered in credits it does not define. RB2B's Pro+ is $199 a month against a published 25-cent meter.
At RB2B's rate, $833 a month buys roughly 3,330 identifications. So the question to put to the more expensive vendor is a plain one: on your traffic, does the agent layer, the chat and the ad retargeting justify the gap? For a site producing a few hundred identifiable visits a month, it does not, and the arithmetic is not close.
The honest caveat is that these are not the same product. RB2B identifies and pushes a notification. Warmly identifies and then works the person across channels. Buying the cheap one and letting the alerts pile up unread in a Slack channel is the most common way to waste either of them, and it is a failure of the buyer rather than of the tool.
What the free plan is really for
150 resolutions a month, company-level only, no person-level identification and no integrations beyond Slack. As a product that is thin. As an instrument it is the most useful thing on the page.
Run it for a month and you learn the number that decides everything downstream: how much identifiable traffic you actually have. If 150 resolutions never fill up, the plan is not your constraint and neither is the vendor. Your traffic is, and no amount of paying will change that.
Setting RB2B Up
A script on the site, a Slack connection, and you are running the same afternoon. This is the least procurement-heavy product in its category by a distance, which is itself part of the argument for it.
- Start on Free for a month and count resolutions rather than reading the demo. It answers whether you have enough identifiable traffic to justify anything paid.
- Decide who acts on an alert before you switch it on. A Slack channel nobody owns is where this product goes to die, and that is true at every price point in the category.
- Ask your legal team about person-level identification first, not after. It is US-only for a reason, and the reason is worth understanding even if you only sell into the US.
- Model your overage before choosing Starter. At 45 cents against Pro's 25, a Starter plan that regularly overshoots costs more than the plan above it.
- Compare basic against premium resolution on your own traffic during the seven-day trial, because the difference between 15-20% and 35-45% coverage is the entire value of the upgrade.
Strengths and Weaknesses
- Publishes its own match rate, which no competitor on this site does, and does not round it up.
- The overage rate agrees with the plan rate on Pro and Pro+, so consumption above the allowance is not a penalty.
- A real free plan at 150 resolutions a month, enough to size your own traffic before paying anything.
- Self-serve, published pricing and a seven-day full-featured trial, in a category that otherwise runs on demos.
- States the US-only limit plainly rather than letting a buyer discover it after signing.
- Contact-level identification is US only, so European traffic gets company-level resolution at best.
- Basic resolution covers 15-20%, which means four in five visitors stay anonymous unless you pay for premium.
- Starter's overage is 45 cents against Pro's 25, so the cheap plan punishes the growth it is supposed to support.
- It identifies and notifies, and stops there. Everything after the alert is your workflow to build.
- Extra domains are $99 a month, which lands hard on agencies and multi-brand companies.
RB2B Pricing
The most legible pricing in this category, and the only one where cost per identified person can be computed from published material rather than estimated after a quote.
| Plan | Monthly | Resolutions | Per resolution | Overage |
|---|---|---|---|---|
| Free | $0 | 150 | — | — |
| Starter | $79 | 300 | $0.263 | $0.45 |
| Pro | from $149 | 600 | $0.248 | $0.25 |
| Pro+ | from $199 | 600 | $0.332 | $0.25 |
Pro+ costs a third more per resolution than Pro and roughly doubles the coverage, from 15-20% up to 35-45%. On those figures the upgrade is the better buy for anyone whose traffic justifies the tool at all, which is an unusual thing to be able to conclude from a pricing page.
The Verdict
The only visitor-identification product here that publishes its own match rate and a meter that agrees with its plan prices, which makes it both the cheapest way into this category and the only one you can model before buying — as long as your traffic is American and you have decided in advance who acts on the alert.
- Your traffic is predominantly US and person-level identification is legal for your use
- You want to size the opportunity before committing, which the free plan allows
- Someone specific will own the alerts and act on them the same day
- You would rather pay per resolution than per year for an undefined credit
- Your buyers are in Europe, where contact-level identification is not offered
- You want the working layer as well as the alert, which this deliberately does not sell
- Your identifiable traffic is thin, in which case no tool in this category is the answer
- You run many domains, where $99 a month for five adds up quickly
