The short answer
RB2B names the people visiting your website, but only for US traffic. Outside the US it shows companies. The main RB2B alternatives are Warm AI, Warmly, Snitcher, Leadfeeder, Albacross and Factors.ai. The right one depends on where your visitors are, whether you need named people, and which tools the data has to reach.
RB2B is one of the data providers inside Warm AI, and we make Warm AI, so we have an interest. To keep this fair, every fact about RB2B comes from RB2B's own website, every price comes from each company's own pricing page, and everything was checked on 8 October 2026.
What RB2B does
RB2B says its pixel "delivers full LinkedIn profiles to Slack for US IPs." Its FAQ says person-level identification "is a US-only technology with a US-only database", and that it identifies people using "a combination of 1st and 3rd party cookies, device IDs, and IP addresses." For companies, it identifies visitors worldwide.
| RB2B plan | Price | What you get |
|---|---|---|
| Free | $0/month | 150 identifications a month, company level only, sent to Slack |
| Starter | $79/month | Named US visitors with LinkedIn profiles, sent to Slack or Teams. No email addresses or other integrations |
| Pro | From $149/month | Adds business email addresses and integrations including HubSpot, Salesforce, Clay, Zapier and webhooks |
| Pro+ | From $199/month | RB2B's Premium Resolution, which it lists at 35 to 45% coverage against 15 to 20% on Pro |
RB2B also offers a 7-day trial of its Pro plan.
Why teams look for an RB2B alternative
There are three common reasons.
Your visitors are not only in the US. RB2B names US visitors only. If a good share of your traffic comes from the UK or Europe, you need strong company-level identification for those visits, not a person-level tool.
You need the data in your CRM without paying for Pro. RB2B's Starter plan sends LinkedIn profiles to Slack or Teams but has no email addresses and no other integrations. CRM integrations start on Pro.
You want one tool for every region. RB2B's person-level data is US only. Some teams want a tool that combines several identification providers, including RB2B, and shows UK and European companies alongside named US visitors.

The 6 RB2B alternatives
1. Warm AI: best for teams with US and UK or European traffic
Warm AI checks several identification providers at once, RB2B and Snitcher along with 7 more data sources, and keeps the best match. US visitors are shown as named people with their LinkedIn profile and email address where available. UK and EU visitors are shown as companies, with the pages they read, and the tracker waits for your cookie banner before recording them. Visitors go to HubSpot, Slack, email alerts, HeyReach, Valley or a CSV on every plan.
Plans start at £89 a month for 50 IDs, where a company uses 1 ID and a named US person uses 2, with no long-term contract and a 14-day free trial with no card needed. Like RB2B, Warm AI does not name UK or EU visitors.
2. Warmly: best for identification, chat and automation in one platform
Warmly identifies companies and people and connects to HubSpot, Salesforce and other CRMs. Its visitor identification plan starts at $10,000 a year, or $4,875 a quarter, and plans with website chat start at $20,000 a year. HubSpot announced on 30 June 2026 that it will acquire Warmly, and said pricing and contracts would stay the same for current customers for now. See our Warmly alternative page.
3. Snitcher: best for low-cost company identification
Snitcher identifies companies and lets you reveal individual contact details when you choose to. It syncs with HubSpot, Salesforce, Pipedrive, Zoho and Microsoft Dynamics. Plans are advertised from $49 a month, with a 14-day trial and no card needed. Snitcher is also one of the providers Warm AI checks.
4. Leadfeeder: best for a free starting point
Leadfeeder identifies companies and has a free plan for up to 100 companies a month with 7 days of history. Paid plans start from €79 a month billed annually and connect to CRMs including HubSpot, Salesforce and Pipedrive. See our Leadfeeder alternative page.
5. Albacross: best for European teams on a budget
Albacross identifies companies, is priced by how many it identifies each month, and offers verified emails and phone numbers with credits. Starter costs €59 a month billed yearly, or €84 monthly, with a 14-day trial and no card needed.
6. Factors.ai: best for account-based marketing and ad reporting
Factors.ai identifies companies and adds account-based marketing tools and features aimed at LinkedIn and Google Ads results. Its person-level identification is an add-on that uses RB2B. It has a free plan, does not publish paid prices, and says it typically bills on annual contracts.
RB2B vs Warmly
| RB2B | Warmly | |
|---|---|---|
| Named people | US visitors only, on paid plans | Companies and people |
| Starting price | Free plan. Paid from $79/month | $10,000/year, or $4,875/quarter |
| Billing | Monthly | Annual or quarterly |
| CRM integrations | From the Pro plan ($149/month) | HubSpot, Salesforce and others |
| Website chat | Not offered on its pricing page | On plans from $20,000/year |
Choose RB2B if you want named US visitors in Slack for a low monthly price. Choose Warmly if you want identification, chat and automation in one platform and have the budget for an annual or quarterly contract. Note that HubSpot announced on 30 June 2026 that it will acquire Warmly.
RB2B vs Lead Forensics
RB2B names US visitors and shows companies elsewhere, with prices from $79 a month. Lead Forensics focuses on company-level identification, gives you business contacts at those companies where available, and does not publish its prices. See our Lead Forensics alternatives comparison.
Does RB2B work in the UK and Europe?
For companies, yes. For people, no. RB2B says its person-level identification is US only and that its database "only contains profiles that have been matched to US home addresses." RB2B also says you "MUST use a consent collection tool if you deploy our global company-wide identification technology."
So for anonymous UK and European visitors, RB2B, Warm AI and most tools here show the company rather than the person. Warmly says its person-level identification is not limited to the US, and some tools, such as Snitcher, can name visitors who fill in a form or log in, or let you look up contacts at the company. The other differences are how many companies each tool identifies, what it costs, and where it sends the data. Our guide to GDPR and visitor identification explains the rules.
How to switch from RB2B
- Start a trial of the alternative and install its tracking code on every page.
- Run it alongside RB2B for at least two weeks on the same traffic.
- Compare named US visitors and identified companies that fit your ideal customer, not the totals.
- Move your Slack alerts, CRM connection and outreach campaigns to the new tool.
- Remove the RB2B pixel once you have switched.
