What it does

A 275-million-contact prospecting database with sequences built in

Apollo is a searchable database of roughly 275 million contacts and companies that you can filter by job title, industry, funding stage, tech stack, and dozens of other attributes, then export or push straight into a sequence or CRM.

On top of the database it layers multi-step outbound sequences (email, calls, LinkedIn touches), an AI sequence composer, a built-in dialer, and basic deal tracking, positioning itself as an alternative to running a data provider, a sequencing tool, and a dialer as three separate subscriptions.

The economics run on a shared credit pool: prospecting, enrichment, exports, and AI features all draw from the same monthly allowance.
