What is Apollo.io?

At its core, Apollo.io is a sales engagement and intelligence platform. It combines a massive, verified B2B contact database with tools to help sales teams discover leads, automate outreach, personalize messaging, and manage the sales funnel from one centralized system.

Imagine having LinkedIn Sales Navigator, ZoomInfo, HubSpot, and Outreach.io all rolled into one, but more agile, cost-effective, and scalable. That’s the promise of Apollo.io.

The platform is used by over 500,000 companies, including major players in SaaS, marketing, fintech, and professional services. It caters to SDRs, AEs, growth marketers, and even recruiters anyone who relies on targeted outreach and high-quality data.

Key Features of Apollo.io
