RB2B watches your website traffic and matches anonymous visitors to real people, then drops their name, title, and LinkedIn profile into a Slack or Teams channel. It runs on a script you drop into your site, no visitor form fill required.
The pitch is speed: a rep sees a named visitor from a target account show up in Slack minutes after they land on a pricing page, and can reach out while the intent is fresh. Coverage is US-only, and how much of your traffic actually gets identified depends on the plan and the visitor's own footprint online.
RB2B runs on a credit system: every plan above Free sets a monthly cap on resolved visitors and bills overage per extra resolution once you cross it.

Who it's for
- ✓ US-focused B2B teams that want warm-lead alerts in Slack without building a data pipeline
- ✓ Outbound and SDR teams that want to layer intent signal onto accounts they're already targeting
- ✓ Small teams that want to start free and only pay once traffic and pipeline justify it
Who should look elsewhere
- ✗ Teams with mostly international traffic, since resolution only fires on US IP addresses
- ✗ Teams that want a flat, predictable bill regardless of traffic swings
- ✗ Teams that need built-in outbound sequencing rather than just identification and alerts
Pros
- + Free plan exists with no credit card, so you can test signal quality before paying
- + Setup is a single script tag, live in Slack within minutes
- + Active public changelog with dozens of fixes and integrations shipped in 2025 and early 2026, though the pace slowed to roughly one update a month by Q2 2026
- + Pro and Pro+ include business email addresses and integrations, not just a name and title
Cons
- – US-only identification; the algorithm doesn't fire on non-US IP addresses
- – Credits burn on any matched visitor, including traffic that isn't your ICP, so noisy traffic inflates your bill
- – Big first paid step: Free caps at 150 resolutions/month and the next tier starts at $79/month with no smaller paid option
- – Overage pricing ($0.25-$0.45 per resolution) can add up fast on high-traffic sites that outgrow their plan's cap
RB2B pricing
What you pay for
You pay per month of visitor-identification credits, not per seat. Every plan above Free caps a monthly resolution count and charges an overage fee once you go over it, so your bill moves with your traffic. Pricing is fully disclosed on the site rather than quote-only. The jump from a 150-credit free plan straight to $79/month is the one number to plan around if your site gets real traffic.
At about $79/month to start, it sits mid-pack on price in Website Visitor Identification.
| Plan | Price | Highlights |
|---|---|---|
| Free | Free | 150 monthly resolutions · Company-level ID only · Push to Slack · No person-level ID, emails, or other integrations |
| Starter | $79/mo | 300 monthly resolutions · LinkedIn URLs pushed to Slack/Teams · No business emails or other integrations · $0.45 per resolution over the cap |
| Pro | $149/mo | 600 to 2,500 monthly resolutions · Business email addresses included · All integrations available · $0.25 per resolution over the cap · Extra domains $99/month for up to 5 |
| Pro+ | $199/mo | Premium resolution with higher identification coverage · Scales from 600 to 2,500,000 monthly resolutions ($199 to $50,000/month) · Business email addresses, all integrations · $0.25 per resolution over the cap · Extra domains $99/month for up to 5 |
Prices are monthly, billed monthly (no listed annual discount on the pricing page). Pro is a per-resolution-volume slider: $149/mo at 600 resolutions, up to $349/mo at 2,500. Pro+ starts at $199/mo for 600 resolutions and its slider goes far higher, to $50,000/mo at 2,500,000 resolutions, for high-traffic sites.

RB2B FAQ
Is RB2B free?+
Yes, there's a free-forever plan with 150 monthly visitor resolutions, but it only gives company-level identification pushed to Slack, not the person's name or contact details.
Does RB2B work outside the US?+
No. Identification only fires on US IP addresses, so international traffic won't resolve.
How does RB2B pricing scale?+
Each plan sets a monthly credit cap (one credit per identified visitor) and charges an overage fee, $0.45 on Starter and $0.25 on Pro/Pro+, once you exceed it. Pro and Pro+ both start at a base price and climb as you pick a higher resolution volume.
What do I get for the business email addresses?+
Business email matching is included starting on the Pro plan; Free and Starter only return company-level or LinkedIn identification.
