Apollo.io

Apollo.io is a sales intelligence and engagement platform that combines one of the largest available B2B contact databases with built-in outreach tools including email sequencing, a power dialer, meeting scheduling, and CRM integration. The contact database contains over 275 million verified contacts and 73 million companies, with data points covering verified email addresses, direct phone numbers, job titles, company size, industry, technologies used, funding stage, and intent signals. Advanced prospecting filters allow users to narrow down the database by job title, seniority, department, company size, funding events, hiring patterns, and buyer intent topics to build targeted lead lists aligned with a defined customer profile. The platform's AI features include email personalization that generates contextually relevant copy based on prospect data, lead scoring that ranks contacts by estimated conversion likelihood, and research automation that compiles prospect and company background before outreach. The integrated power dialer supports local presence calling, voicemail drop, call recording, and automatic CRM logging, with the Professional plan including 4,000 minutes of recorded calls with AI-generated conversation insights. Apollo.io is used by B2B sales development teams building outbound prospecting pipelines at volume, by account executives managing multi-touch sales cycles who need engagement tracking across email, phone, and meetings, and by agencies or revenue operations teams maintaining clean, enriched contact data through automated waterfall enrichment. A standard outbound workflow involves applying prospecting filters to identify target contacts, adding them to an automated email sequence with scheduled follow-ups, conducting calls through the built-in dialer, and tracking engagement within Apollo.io's pipeline management interface or syncing activity to Salesforce or HubSpot.
