RB2B

aid: rb2b
name: RB2B
description: RB2B is a US-focused B2B website visitor identification platform that resolves anonymous web traffic into person-level
  leads — names, LinkedIn profiles, hashed and plaintext business emails, mobile ad IDs, and full business profiles — and
  pushes them to sales, marketing, and ad-tech systems. The product is delivered as a JavaScript pixel plus a knowledge- base
  and pipeline of 50+ destination integrations (Slack, Microsoft Teams, Salesforce, HubSpot, Clay, Zapier, Apollo, Customer.io,
  Demandbase, and others), with global company-level identification and US-only person- level resolution. RB2B operates a
  separate API Partner Program at api.rb2b.com that exposes credit-metered Identification endpoints (IP → HEM, IP → MAID,
  IP → Company Domain) and Enrichment endpoints (HEM → LinkedIn, HEM → Business Profile, HEM → MAID, LinkedIn → Email, LinkedIn
  → Phone, Email → LinkedIn, Email → MAID) for SaaS developers, GTM engineers, retailers, and ad-tech platforms that want
  to embed identity resolution into their own apps and identity graphs. The platform is SOC 2 Type II certified.
