Leadfeeder vs. Apollo.io

Leadfeeder is a B2B website visitor identification and lead generation platform that reveals which companies are visiting a website and turns anonymous web traffic into actionable sales and marketing intelligence. It helps B2B marketing, sales, and revenue operations teams see which companies are visiting their site, even when those visitors never fill in a form, so they can follow up while interest is high. Leadfeeder identifies the companies behind anonymous website visitors by matching web traffic to an IP-to-company database of 60M+ companies and 400M+ verified contacts.

Apollo.io is an AI-powered go-to-market (GTM) platform that helps revenue teams find, engage, and manage B2B buyers across the entire sales cycle. Apollo.io is the company behind the industry’s first fully agentic GTM platform, transforming how revenue teams execute. Going beyond automation, Apollo’s intelligent agents actively drive results across the entire sales funnel – from prospecting to deal management – all in one place.
