RB2B made person-level website visitor identification cheap and quick to set up, which is why it spread fast among US sales and growth teams. The same design choices are why people look for RB2B alternatives: person-level identification only covers US traffic, the vendor says it does not target EU or UK markets, and the product stops at the alert. What happens on the website itself is out of scope.
The alternatives below cover each of those gaps. If you are deciding between company-level and person-level identification in the first place, our explainer on how company-level visitor tracking works sets out the differences.
Disclosure: this page is published by Markettailor, which is one of the options listed. Product details were checked against each vendor's own website in October 2026; products and pricing change, so confirm before you buy.
What RB2B Does
RB2B names retention.com as its parent company.
RB2B is a website visitor identification tool installed as a pixel. It identifies companies globally and, for US traffic, individual visitors (LinkedIn profiles, and business emails on paid plans), then pushes them to Slack, Teams, CRMs and outreach tools. It is mainly used by sales and growth teams that want to follow up quickly with specific people who visited.
Where RB2B is strong
- Self-serve pricing, including a free plan with 150 monthly resolutions.
- Quick setup: a header pixel plus a Slack, Teams or CRM connection.
- Hot Leads filters route visitors by revenue, company size, seniority, department and geography.
- Connects to outreach and data tools such as Clay, Instantly and HeyReach as well as CRMs.
Pricing
Free: $0 per month (150 resolutions, company-level identification, Slack push). Starter: $79 per month (300 resolutions). Pro: from $149 per month (600 to 2,500 resolutions). Pro+: from $199 per month. Overage per resolution: $0.45 on Starter, $0.25 on Pro and Pro+. (Source: RB2B pricing page, checked October 2026.)
Why Teams Look for RB2B Alternatives
- Your buyers are outside the US, where RB2B resolves companies only.
- You sell into the EU or UK and want a vendor built around GDPR obligations.
- You want the website to respond to the companies visiting, not only alert sales.
- Overage costs on resolutions are hard to predict for your traffic.
The Best RB2B Alternatives
1. Leadfeeder
Visitor identification and reverse IP · Leadfeeder alternatives
The most established company-level option, with a free plan, euro pricing tiered by identified companies, and native integrations with five major CRMs. A better fit than RB2B for European teams that want account-level visit data rather than names.
2. Markettailor
B2B website personalization
Markettailor identifies companies (never individuals) and changes the website for them: industry-specific case studies, size-matched proof and target-account headlines, tested against a control. Pick it if your goal is converting more of the accounts already visiting, rather than a longer list of people to email. See ABM personalization.
3. Warmly
Visitor identification and reverse IP · Warmly alternatives
If you like RB2B's person-level approach but want to engage visitors in the moment, Warmly adds AI chat, meeting booking, popups and retargeting on top of identification. It is priced as an annual platform, starting at $10,000 a year.
4. Albacross
Visitor identification and reverse IP
A Sweden-based alternative with EU-focused identification, fit and intent scoring, contact data and outreach sequences, priced in euros with monthly or yearly billing.
5. Clearbit
Visitor identification and reverse IP · Clearbit alternatives
For HubSpot customers, native buyer intent shows which target-market companies are on the site, and enrichment fills contact records, without another pixel or vendor.

How to Choose
- Map your traffic by country first; person-level US identification does nothing for a mainly European audience.
- Ask legal which identification level you can use in each market before you trial anything.
- Decide what should happen after identification: an alert, a CRM record, a chat, or a different web page.
- Model cost at your real monthly volume, including overage.
