Apollo.io

Apollo.io is an AI heavy sales intelligence and engagement platform, used by sales teams and SDRs to find verified contact data, run email sequences, and execute multichannel outreach across the prospecting and engagement program through a B2B contact database with email, mobile, and dialer features layered across the established platform that has been built around prospecting and outreach for many years across global sales markets and customers language communities today.

Apollo.io fits SDR teams, founders, and growth stage sales teams that want a serious sales intelligence and engagement platform with a free starting tier and credit based paid plans, rather than an enterprise data tool with sales led pricing and lengthy contract cycles. Public reviews note data accuracy varies by segment and credit limits can pinch heavy users. Pricing has free and published paid tiers across global sales markets today.
