10 Tools to Buy Business Leads + PowerDialer to Close Fast

Not long ago, buying business leads felt like rolling the dice. You’d pay for a list, only to find half the contacts were outdated or worse, fake. But in 2025, that’s no longer the case.

Thanks to smarter tools and stricter compliance standards, it’s now possible to get direct access to verified, GDPR/CCPA-compliant, and highly-targeted B2B leads. Even better, when you pair those leads with the right outreach tools, you’re not just buying names, you’re building real conversations and converting faster.

In this blog, we’ll introduce you to 10 of the best lead buying platforms available right now, each with different strengths, from global data coverage to built-in email outreach. And once you’ve got those leads in hand, we’ll show you how to turn them into booked meetings using one powerful sales tool: PowerDialer.ai.

Let’s dive in and explore what works, what doesn’t, and how to make lead buying part of your actual growth engine.

Why Buying Leads Is Smart (When You Do It Right)

Old-school lead buying was a mess. You’d get outdated spreadsheets, bad emails, and fake job titles.

Today, it’s a different story, modern B2B lead tools offer:

• Verified emails and direct dials (often human-verified)
• GDPR & CCPA compliance
• Buyer intent signals (who’s ready to buy)
• CRM-ready exports
• Filters by job title, tech stack, industry, region

“We bought 1,000 leads from Cognism, plugged them into PowerDialer, and booked 30 qualified meetings in two weeks,”
Sarah, SDR Manager at a Series A SaaS company
