RB2B is a website visitor identification and B2B enrichment platform that resolves anonymous website traffic into person-level identity data. It matches IP addresses, hashed emails, and LinkedIn profiles against its data graph to surface who is visiting a site and how to reach them.
With RB2B, you can:
- Resolve IPs into identity signals: Convert an IP address into hashed emails, mobile advertising IDs, or company domains
- Enrich emails and LinkedIn profiles: Turn a hashed email or LinkedIn slug into a full business profile with name, title, company, and contact details
- Look up contact and activity data: Retrieve mobile phone numbers, personal emails, and last-active dates for a known contact
- Search for people: Find a LinkedIn profile from a first name, last name, and company domain
In Sim, the RB2B integration allows your agents to identify anonymous website visitors and enrich them into actionable contact records — resolving an IP address to a company or hashed email, expanding a hashed email or LinkedIn profile into a full business profile, and retrieving mobile phone numbers or personal emails for outreach. Agents can also check remaining API credits and confirm when a contact was last active, making the integration useful for lead identification, sales prospecting, and B2B enrichment workflows.
Resolve IP addresses, hashed emails, and LinkedIn profiles into person-level identity and B2B enrichment data using the RB2B API. Convert IPs to hashed emails, MAIDs, and company domains; enrich emails into LinkedIn profiles, business profiles, and mobile IDs; and look up emails or phone numbers from LinkedIn. Requires an RB2B API key.
Check the number of API credits remaining on your RB2B account.
