Overview
Apollo combines B2B contact and company data with prospect search, enrichment, sales engagement and outreach workflows. Teams can build lists, research accounts, find contact details, manage leads and run sequences from a connected workspace. Apollo AI adds natural-language research, list building, writing assistance, conversation insights and workflow automation. The service also exposes an API, a hosted MCP connection and official CLI and MCP repositories for developers and AI-compatible tools. It is a proprietary hosted product rather than an open-source application.
