Apollo combines prospecting data and outreach automation at pricing well below ZoomInfo ($15,000+/year). The 275 million contact database includes verified emails and phone numbers. Built-in sequence automation competes with Outreach and Salesloft. AI email personalisation generates outreach incorporating company news, funding, and tech stack signals at scale. Data quality has historically lagged ZoomInfo but the gap has narrowed substantially.
Apollo.io AI runs as writing assistant software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, chrome extension, and ios, with API access for teams that want to embed it into their own products.
