Best Lead Generation Tool for B2B (Fintech & Financial Services)?

Hey everyone,

I'm new to B2B sales and trying to build a solid lead list for my startup. We create animated explainer videos, and our main target audience is financial services and fintech companies in the UAE

There are so many tools out there—Apollo, ZoomInfo, Lusha, Seamless.ai, Clay, etc.—and I want to make sure I invest in one that actually delivers quality leads. I need a tool that helps me find accurate company and contact data, ideally with good filtering options so I can target the right prospects (decision makers) efficiently

For those who have experience in B2B lead generation, especially in fintech/financial services, what tools have worked best for you? Any underrated ones I should check out?

Thanks in advance for your help!
