Apollo.io combines a 210M+ contact database, outbound automation, data enrichment, and deal tools in one AI sales platform, with a free plan and paid tiers.
Apollo.io is a sales intelligence and engagement platform founded in 2015 and headquartered in San Francisco, California. It positions itself as a unified alternative to stitching together separate prospecting databases, outreach tools, and enrichment services.
The platform is built around a large B2B contact and company database combined with automation for outbound and inbound sales workflows, deal execution support, and reporting, used by over 600,000 companies according to Apollo.
Apollo's B2B database provides verified emails and phone numbers across 210M+ contacts and 30M+ companies with searchable filters. Outbound automation supports AI-assisted multichannel sequences with email deliverability safeguards, while inbound tools include real-time form enrichment and anonymous website visitor identification.
Additional capabilities include data enrichment and record cleansing, AI-generated call summaries and conversation analytics, pipeline boards for deal management, task prioritization and workflow automation, and a Chrome extension for finding contact details directly on LinkedIn and other web pages.
Apollo.io offers a free-forever Starter plan with access to its contact database and limited monthly credits. Paid plans — Basic, Professional, and Organization — are billed per user and are less expensive when billed annually than monthly; the Organization tier requires a minimum of three users and adds features such as an international dialer, custom reports, advanced security controls, and API access.
Trial periods on paid plans include a set number of credits and most features of the selected plan, and larger organizations with custom integration or security needs can request enterprise pricing.
