Apollo.io
The AI GTM system for go-to-market teams.
Apollo is a unified go-to-market platform that combines B2B contact data, AI-driven intelligence, and sales execution tools in one connected system. It addresses the problem of fragmented prospecting and engagement workflows by bringing data, agents, and outreach into a single environment, while also allowing teams to connect Apollo to the tools they already use.
Key capabilities include Apollo Data with access to a large B2B contact and account dataset, Waterfall Enrichment that draws on multiple data sources to complete records, and first-party data integration with CRMs, data warehouses, call recordings, and calendars. The Intelligence layer includes Apollo Profile for unified contact and account views, AI agents for research, list building, outreach, and follow-up, and an AI Context Center for training agents on ideal customer profiles and products. Execution tools include a Workspace for prospecting and outreach, Apollo Anywhere for working from tools like CRM, Gmail, and AI assistants, a Chrome Extension, a Parallel Dialer, and Builder Studio for custom AI systems. The platform offers more than 200 integrations and supports compliance features including consent and opt-out handling.
Apollo is designed for sales, revenue operations, marketing, and developer teams, as well as founders and small businesses through to mid-market and enterprise organizations. It offers a free sign-up option without a credit card, and enterprise features such as governance, admin controls, permissions, and security certifications including SOC 2 Type II and ISO 27001.
