It gives access to business contacts with phone numbers, emails, and firmographic data.
One thing that stands out is its focus on GDPR-compliant data, which matters a lot in the UK.
From what I’ve seen, Cognism feels more like a premium data provider, not a flexible search tool.

Apollo.io is an all-in-one sales platform that combines lead data, outreach, and CRM features.
I’ve seen it work best when you want one place to find leads, enrich data, and run outreach.
Features like AI assistant, sequences, dialer, and workflow automation make it more than just a database.
What stands out to me is the combination of a large contact database and built-in outreach tools, which reduces tool sprawl.
But at the same time, because it does everything, it can feel feature-heavy and slightly complex at first.
