Apollo

Apollo is a B2B sales intelligence and engagement platform with a contact database, sequencing, and AI-assisted prospecting for revenue teams.

Overview

Apollo combines a database of hundreds of millions of business contacts with email and phone engagement tooling. Teams search for prospects using firmographic and intent filters, enrich records, and enroll them in multi-step sequences with automated follow-ups. AI features write personalized emails, recommend the next best accounts, and score leads by fit and buying signals. Native CRM sync keeps Salesforce and HubSpot records current, which makes Apollo a common system of record for outbound motion. Its intent and hiring signals help reps prioritize accounts that are actively changing, which tends to correlate with openness to new vendors.

Paid tiers expand enrichment credits and add advanced governance for larger teams.
