Best Overloop Alternatives for 2025

Alright, so I’ve been deep in the B2B lead gen game for a while now, and honestly, Overloop was solid back in the day—great for cold outreach and sales automation. But let’s be real… it’s 2025, and there are way better tools out there for B2B prospecting, especially when it comes to finding verified contacts, syncing with your CRM, and building scalable campaigns. If you’re looking for smarter B2B Leads Database Providers or just fed up with Overloop’s limitations, I got you.

Here are the best Overloop alternatives I’ve personally tested—warts and all.
