Are there any good databases for leads?

There are many good lead databases out there. I have listed them in detail in my business databases blog and shared my reviews.

And here are the databases that work well for finding verified leads:

1. Saleshandy - Great for finding B2B leads globally - Built-in AI Lead Finder + cold outreach stack - Verified contacts, compliance-ready

2. Apollo.io - Massive database (270M+ contacts) - Advanced filters, tech install data, intent signals

3. Cognism (best for GDPR-compliant EU leads) - Strong in UK/EU regions - Diamond Data® for verified mobile numbers
