Sales intelligence platform with 265M+ contacts, email finding, sequence automation, and developer APIs for building custom prospecting workflows.
Apollo.io is a sales intelligence platform that gives you access to 265 million business contacts and 30 million companies. Unlike basic contact databases, Apollo combines prospecting with outreach automation, so you can find leads and email them from the same platform. The contact data is strongest for US tech companies, where you'll find direct emails for 70-80% of employees at most SaaS companies.
The email finder is Apollo's standout feature. Paste a company domain and get a list of employees with their likely email addresses. The verification system checks deliverability before you send, which protects your sender reputation. For common patterns like firstname@company.com, accuracy hits 85-90%. More creative email formats or smaller companies see lower success rates.
