What is Apollo.io?
Apollo.io combines a B2B database of 275M+ contacts, an email finder, and a sales engagement platform into one tool. You can search for ideal prospects, find their verified emails, and run multi-step outbound sequences — all without switching tools.
Its killer advantage is the all-in-one workflow: prospecting, data enrichment, and outreach live in the same platform, which dramatically reduces the tool sprawl most sales teams deal with.
