RB2B vs Dealfront (Leadfeeder)
Both are alternatives to Clearbit (HubSpot Breeze Intelligence). Here's how they stack up — verified facts, no spin.
Also searched as Dealfront (Leadfeeder) 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.
Dealfront (Leadfeeder)
The European option, built around GDPR rather than apologising for it.
Dealfront is the merger of Leadfeeder and Echobot, and its distinguishing feature is jurisdiction: it is a European company with European data handling, built for GDPR from the start rather than retrofitted. For a company selling into Europe — or one whose legal team has already asked hard questions about this category — that is frequently the deciding factor rather than a nice-to-have. It identifies companies rather than individuals, integrates with the major CRMs, and its European company data is the deepest here. Company-level only, which is both the privacy story and the functional limit.
