Apollo.io

All-in-one sales platform with a large B2B contact database, enrichment, sequences, and a dialer for outbound prospecting.

by Apollo.io

What it does

Apollo.io combines a large B2B contact and company database with the execution tools needed to act on it, including email sequences, a dialer, task management, and a Chrome extension that surfaces contact data on LinkedIn and company websites. Reps can search the database by title, industry, technology, and other filters, then push prospects directly into outreach sequences without leaving the platform.

The platform also covers enrichment and CRM hygiene, updating records with firmographic data and verified contact details, and it includes AI features for drafting emails and recommending prospects that match an ideal customer profile. Because data and engagement live in one product, smaller teams often use Apollo instead of buying a separate database and a separate engagement platform.

Data quality is generally regarded as strong for emails and more variable for phone numbers, which is typical for the category. Apollo publishes its pricing, including a free tier, which makes it one of the easier platforms in this space to evaluate.
