Apollo.io
Apollo.io is a sales platform that combines a large B2B contact database with prospecting, outreach, and deal workflows in one place. Sales and marketing teams use it to find verified emails and phone numbers, run email sequences, enrich CRM records, and track pipeline without juggling separate data and engagement tools.
What sets Apollo apart is how tightly the data layer connects to execution. Its database covers 230 million contacts and 30 million companies, with 65+ filters for firmographics, intent signals, and job changes. The built-in AI Assistant can build prospect lists, draft personalized sequences, and run research tasks inside Apollo rather than exporting to another tool.
The platform is built for outbound reps, SDR teams, account executives, revenue operations, and founders who need to move from lead list to booked meeting quickly. Chrome and Gmail extensions let reps prospect on LinkedIn and the web, while native CRM integrations keep Salesforce and HubSpot records in sync.
