Let’s be real: Seamless.ai has its moments—but it ain’t perfect. Whether it’s outdated contacts, clunky UX, or just not giving me enough bang for my buck, I started shopping around for better B2B lead generation tools. If you’re also tired of chasing dead-end leads and inflated promises, here’s my no-fluff breakdown of the best Seamless.ai alternatives I actually use (and trust) for building targeted B2B lead lists.
These tools are killer for B2B sales prospecting, scraping quality contacts, and scaling outreach without pulling your hair out.
1. ZoomInfo – The OG B2B Leads Database
Let’s start with the elephant in the room. ZoomInfo is basically the gold standard when it comes to B2B lead generation databases. Insane amount of data, and super deep filters.

-
Org charts, intent data, tech stack info—chef’s kiss

Overkill if you’re a solo founder or tiny team
