Look, I love what Clay is doing with automations and integrations, but if you’re mainly after quality B2B leads, faster prospecting, and solid data—you’ve got way better options out there. I’ve tested a ton of lead generation databases and here’s what actually worked for me in 2025.
1. ZoomInfo – The Data Giant
What it does:
ZoomInfo is the big dog when it comes to B2B leads database providers. It’s got company insights, verified contacts, org charts—basically everything.
Why I like it:

Intent data is 🔥. Helps you target buyers who are actually ready.
-
Their ReachOut Chrome extension is a time-saver.
What I don’t love:
-
Super pricey. Not ideal if you’re bootstrapped.

Price: Custom pricing only. Get ready to talk to sales.
