About Apollo

Apollo provides an AI GTM system that unifies data, intelligence, and execution to support go-to-market teams. It aims to replace fragmented tools with one connected platform and offers data, AI-driven insights, and execution capabilities across prospecting, outreach, and deal management. It targets sales, marketing, RevOps, and enterprise teams seeking alignment and efficiency.

Apollo presents three layers—Data, Intelligence, and Execution—where data feeds intelligence, which drives execution, and execution creates more data. It emphasizes a single source of truth with a unified view of every prospect and account, incorporating first-party data, third-party signals, and Salesforce or HubSpot records to keep records fresh and ready to act on.

The platform highlights features such as a unified profile for contacts and accounts, an AI context center to tailor agents to ICPs, and automatic prospecting from goal to booked meetings. It also stresses governance and admin controls for large organizations and claims security certifications and enterprise-grade compliance built into the system.

Apollo frames its product as a platform that can be used by founders, growing revenue teams, RevOps, and enterprises alike. It emphasizes integration with many tools and data sources, and positions its data and AI components as core to enabling a connected GTM workflow rather than a collection of isolated tools.

Frequently asked questions

What is Apollo and what does it do?

Apollo is the GTM agentic system that unifies your data, makes it intelligent, and puts it to work — to help your team know exactly who to target, what to say, and what to do next.

What is GTM Harness?

The GTM Harness is Apollo's purpose-built intelligence engine — not a separate product you log into, but the layer running underneath Workspace, Apollo Anywhere, and Builder Studio (coming soon).

What surfaces does GTM Harness power?

Every surface it powers is designed to work with your reps, not around them. Autonomy is tiered and earned: agents start with guided recommendations and can execute more independently as your confidence builds.

Can I bring my own data and signals into Apollo?

Yes. Connect your CRM, data warehouse, call transcripts, calendar, emails, deals, and third-party data sources.

Is Apollo data compliant with regulations?

Apollo is committed to privacy-by-design, structuring its privacy program around major global frameworks such as the GDPR and CCPA.
