Also searched as Dealfront (Leadfeeder) vs RB2B — same comparison, one verdict.
RB2B and Dealfront (Leadfeeder) are closely matched on ownership (38 vs 41) — this one comes down to pricing and to which trade-offs below you can live with.
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.

Choose RB2B
if person-level rather than company-level identification.
Choose Dealfront (Leadfeeder)
if a lower exit cost matters more to you than any single feature, and european company with GDPR built in, not bolted on.
Neither, yet
if both carry a real cost you should weigh first — uS traffic only — useless for a primarily international audience, and company-level only — no person-level identification. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
RB2B vs Dealfront (Leadfeeder) — common questions
Is RB2B a better fit than Dealfront (Leadfeeder) for visitor identification & personalisation?
It depends on what you are optimising for, and the honest split is this: Dealfront (Leadfeeder) scores 41 to RB2B's 38 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. RB2B earns its place on a different axis — person-level rather than company-level identification. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Neither of these is local-first by default, so plan the exit at the point you adopt rather than later. Export what matters on a schedule instead of trusting you can retrieve it on demand — that is the most common way a visitor identification & personalisation migration turns into a project instead of an afternoon.
