Comparison · Visitor identification
Leadfeeder vs Apollo.io
The short answer
Leadfeeder starts from your website: it names the companies visiting and shows what they read, so sales can prioritise accounts already showing interest. Apollo.io starts from a database: it helps you find and contact people at companies that fit your profile, with its own visitor tracking as one feature. Inbound-led teams tend to start with Leadfeeder; outbound-led teams with Apollo. Many use both.

The choice usually follows how your pipeline is built. If most deals start with prospects finding you, visitor identification shows which accounts are warm. If you need to create pipeline from scratch, a database with outreach gets you further.
Mind privacy either way. Company identification is generally lower risk than contact enrichment and cold outreach, which bring GDPR and electronic marketing rules into play in the EU and UK.
