About Apollo.io
Apollo.io is an all-in-one sales intelligence and prospecting platform: a large B2B contact database, email sequencing, a dialer, buying intent and a Chrome extension, plus AI, in one tool. You find leads, enrich them and run outbound β all in the same place.
It's the default for founders and small sales teams who want a database *and* the outreach tooling without stitching together three separate vendors, and its free plan makes it easy to start.
