Apollo

Apollo is an AI sales platform that integrates data, intelligence, and execution workflows for go-to-market teams to manage prospect outreach and pipeline.

Apollo is a go-to-market system that combines a database of over 240 million contacts and 30 million accounts with AI-driven execution tools. It functions through three layers: a data layer for contact and account information, an intelligence layer using AI agents to research and prioritize leads, and an execution layer for sequencing and outreach. The platform allows users to manage prospecting, emailing, and calling directly within the Apollo workspace or through external integrations. AI agents can be trained on specific business contexts to automate tasks like list building, meeting scheduling, and outreach follow-ups. It is designed for sales teams, marketing departments, and go-to-market operations professionals.
