Rapportive

Rapportive was a browser extension that added a contact-intelligence sidebar to Gmail, surfacing a person's name, photo, job, and social profiles alongside their email. Founded in 2011 and backed by 500 Global (then 500 Startups), it was acquired by LinkedIn in 2012 and later folded into LinkedIn Sales Navigator. The rapportive.com domain now 301-redirects to LinkedIn's "Sales Navigator for Gmail" feature page. Rapportive published no standalone developer API and operates no independent developer surface today; this profile records that defunct/absorbed status for the API Evangelist network.

Rapportive is profiled on the APIs.io network. Tagged areas include Company, Contact Intelligence, Email, Gmail, and Sales Intelligence.
