apollo.io

A massive, all-in-one sales intelligence and execution platform featuring an AI-driven database of over 275 million B2B contacts.

About Apollo.io

Apollo.io has rapidly become the dominant operating system for modern B2B sales teams. Historically, a sales team had to buy expensive leads from one company (like ZoomInfo) and use a completely different software (like Outreach) to actually email them. Apollo seamlessly unifies both the data and the execution into a single, highly intelligent platform.

The platform boasts a massive, constantly updated database of over 275 million global B2B contacts. A sales rep can use highly granular filters to find 'VP of Engineering at software companies in Texas using AWS.' With one click, the rep can instantly reveal their verified email and direct-dial phone number.

Crucially, Apollo heavily integrates AI into the execution phase. Once the leads are selected, the built-in AI writing assistant can automatically draft highly personalized cold emails based on the prospect's recent LinkedIn posts. The platform then automates the entire multi-step follow-up sequence, tracking opens and clicks to mathematically optimize the sales pipeline.
