Why Real Reviews Beat Vendor Marketing Every Time
Lead gen software vendors all claim 95%+ accuracy, millions of contacts, and "AI-powered" everything. But 67% of B2B buyers say vendor claims don't match reality, according to TrustRadius' 2024 Buyer Disconnect report. This review is different: we tested 7 platforms with real SDR teams over 90 days, tracking bounce rates, time-to-list, and rep satisfaction.
Here's what we actually found.
