About Apollo.io

Apollo.io is a sales intelligence and engagement platform built to help B2B teams find leads, automate outreach, and close deals faster. It combines a database of 210M+ contacts and 30M+ companies with tools for email sequencing, a built-in dialer, meeting intelligence, and pipeline management — all in one platform instead of stitching together separate tools. Its AI features speed up prospect research, help draft personalized outreach, and summarize sales calls, while intent data and website visitor tracking help surface accounts that are already in-market. Apollo integrates with major CRMs (Salesforce, HubSpot, Pipedrive) and sales tools (Salesloft, Outreach, Slack, Zoom), and scales from solo founders on a free plan up to enterprise sales orgs with SSO/SCIM and audit logs.
