Best Overloop Alternatives for 2025

Hey there!
If you’re like me, you’ve probably loved parts of Overloop (solid for cold emails) but hit a few walls when it came to lead gen at scale. I went down the rabbit hole trying every possible B2B Lead Generation tool out there. Some were 🔥, some… not so much.

Here’s my no-BS list of the best Overloop alternatives you should 100% check out in 2025 if you’re serious about growing your B2B Leads Database. Let’s get into it:

1. ZoomInfo — The OG for Enterprise-Grade Leads

How it works:
ZoomInfo basically scrapes half the internet (legally, lol) and serves up super-detailed Business Leads across industries. It’s like having a CIA database for B2B prospecting.

Core features:

• Massive Lead Generation Database (literally millions of contacts)

• Intent signals (know who’s actually looking for your service)

• Buyer intent + org charts + technographics

What I liked:

• Crazy accurate data

• Super strong filtering

• Seamless CRM integrations

What sucked:

• Price. 😭 It’s not cheap.

• Bit of a learning curve for newbies

Pricing:
Think $$$$. It’s “talk to sales” territory. They tailor the price to your company size.

My take:
If you’ve got a decent budget and want hands-off lead sourcing, ZoomInfo’s a beast. Worth it if you’re scaling big.

2. RocketReach — Best for Quick Lead Sniping

How it works:
RocketReach lets you plug in a name or company and instantly get emails, phone numbers, and social profiles. Super straightforward.

What I liked:

• Super easy UI

• Pretty good hit rate

• No crazy setup

What I didn’t like:

• Limited data enrichment

• Not great for super niche industries

Pricing:
Starts around $53/mo. Pay-per-use style is also there if you don’t wanna commit.

My take:
Perfect if you just need quick business contact data and don’t wanna mess around with long onboarding.

3. Kaspr — Great for Instant Leads via LinkedIn

How it works:
Kaspr hooks into LinkedIn and lets you pull verified emails + phone numbers while you’re browsing profiles. It’s like cheat codes for LinkedIn prospecting.

• Smooth LinkedIn extraction

• Great for SDRs

• Super clean interface

What I didn’t like:

• Not built for huge team scaling

Pricing:
Starts at €30/mo (~$32). Pretty affordable.

My take:
If your sales team lives on LinkedIn, Kaspr is a must-have B2B Lead Generation tool. Small cost, big impact.

4. LeadIQ — Best for Outbound Teams
