Apollo.io›Apollo.io› offers Apollo Chrome Extension

The Apollo Chrome Extension embeds Apollo's prospect data and outreach actions into third-party web surfaces, letting users find verified email addresses and phone numbers directly within LinkedIn, CRM, and Gmail, place dials, and push prospects into Apollo lists or sequences. It surfaces real-time account and contact insights on target company websites and integrates with tools such as HubSpot through a push feature. Apollo cites more than one million sellers using the extension and reports 98 percent email accuracy backed by its contributor data network.

The extension is free to install and is available across all Apollo plans, including the free tier, with an Apollo account required. It is a long-running, standalone buyer-facing offering with its own product page, listed both under the site's Features navigation and as a component of Apollo Anywhere.
