RB2B vs Plausible + your own enrichment
Both are alternatives to Clearbit (HubSpot Breeze Intelligence). Here's how they stack up — verified facts, no spin.
Also searched as Plausible + your own enrichment vs RB2B — same comparison, one verdict.
RB2B
TOP PICKPerson-level identification for US traffic, with a genuinely free tier.
RB2B identifies individual visitors — name and LinkedIn profile, not just the company — and pushes them to Slack in real time. That is a meaningfully different product from company-level tools, and the free tier makes it the cheapest way to find out whether visitor identification is useful for your business at all before anyone signs a contract. Two constraints are stated openly by the vendor and belong here: it covers US traffic only, and person-level identification is a stronger privacy claim than company-level, which is exactly why it is US-only. Run it past whoever owns privacy at your company before switching it on.
Plausible + your own enrichment
The honest self-hosted answer: analytics you own, identification you do not.
There is no open-source visitor-identification tool, and the reason is structural rather than incidental — the product is an IP-to-company database maintained commercially, not an algorithm anyone can reimplement. What you can own is the analytics layer underneath. Plausible is AGPL-3.0, self-hostable, cookieless and GDPR-friendly, and it will tell you what people did on your site without sending any of it to a third party. Pair it with manual enrichment on the accounts that matter and you have most of the value with none of the privacy exposure. Listed to be straight about where the line is: this is the only entry on the page you can actually run yourself, and it deliberately does less.
