RB2B vs Algomo
Both are alternatives to Clearbit (HubSpot Breeze Intelligence). Here's how they stack up — verified facts, no spin.
Also searched as Algomo 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.
Algomo
Identification plus what to do about it — personalisation and an AI SDR.
Algomo starts where the identification tools stop. It de-anonymises the visitor, then acts on it: adapting headlines, content and calls to action per account, running an AI inbound agent that qualifies and books meetings, generating personalised landing pages for outbound sequences, and syncing personalised copy to LinkedIn ads. The pitch is that identifying a visitor is worth nothing unless something changes as a result — which is a fair criticism of the category. Plans start around $200/month with no per-seat pricing. Note when auditing links: algomo.com currently redirects to newmode.ai, and the company still trades as Algomo.
