| 6 |  Apollo.io Apollo.io is a B2B contact database welded to an outbound execution tool, which is what separates it from a pure data vendor. You filter companies and people by title, headcount, industry, geography and intent signals, reveal work emails and mobile numbers, then push those contacts straight into multi-step sequences, a built-in dialer or your CRM without exporting anything. Around that it records and transcribes sales calls, scores leads, routes inbound form fills, identifies anonymous website visitors and re-enriches stale CRM records on a schedule, including when a contact changes job. A Chrome extension does the same reveal-and-sequence job from LinkedIn. It is built for teams running high-volume outbound, mainly in the US — the further you get from that, the weaker the value. | 85/100 | Visit → |
