Tool
Apollo
Also known as: Apollo.io
All-in-one enrichment + sequencer platform — strong in the US, decent in EU, popular as a beginner platform.
Apollo.io combines prospect data, enrichment APIs, and email sequencer in one platform. Strong product-market fit for teams wanting to start quickly without chaining multiple tools.
Apollo's data is stronger in the US than in EU. For European prospects we typically recommend a combination: Apollo for US focus, Cognism or LeadMagic for EU. Apollo is also often used as one layer in a Clay waterfall.
