Apollo.io is a sales intelligence and engagement platform that combines a large B2B contact database with outreach automation tools. It allows sales and GTM teams to find prospects, enrich contact data, and execute outreach sequences all within a single platform. For teams building outbound systems, Apollo is one of the most widely used tools available.
What Does Apollo.io Do?
Apollo.io serves two primary functions. First it provides access to a database of over 275 million contacts and 60 million companies that you can search and filter based on your ideal customer profile. Second it provides outreach tools that allow you to build and execute email sequences, track engagement, and manage your outbound pipeline directly within the platform.
How Apollo.io Works
You start by defining your ideal customer profile and using Apollo’s search filters to build a targeted prospect list. Filters include job title, company size, industry, geography, technology stack, and many more. Once you have your list, you can enrich the contacts with verified email addresses and phone numbers, then enroll them directly into outreach sequences without leaving the platform.
Apollo.io and Your CRM
Apollo.io integrates natively with CRM platforms like HubSpot. This integration allows you to sync contacts, track email engagement, and ensure that every prospect interaction is captured in your CRM automatically. When a prospect replies or books a meeting, the activity is logged without any manual data entry.
Apollo.io and Data Enrichment
While Apollo provides a strong data foundation, many teams supplement it with additional enrichment tools like Clay to add depth and accuracy to their prospect records. The combination of Apollo for prospecting and Clay for enrichment gives GTM teams a powerful and flexible data infrastructure.
