10 Best Lead Generation Agencies in 2024

Ah, yes—you’re on the hunt for the best lead generation agencies.

Without a steady supply of qualified leads, businesses cannot exist, let alone thrive. That’s why the main function of marketing and sales teams across all industries is to reach new people and convert them into paying customers. 

Nevertheless, some companies prefer to partner with agencies to aid in their lead generation efforts.

Not only do these agencies bring specialized knowledge and advanced lead generation tools to the table, but they also free up time for companies to focus more on their core products and services.

The problem, however, is that there are hundreds if not thousands of lead generation agencies out there—all of them professing to be experts that will help you get the shiniest, most qualified leads that exist. 

It can be challenging to figure out which ones are legitimately good at lead generation and which ones aren’t. So I’ve done the groundwork for you and prepared an overview of the 10 best lead generation agencies in 2024.

Let’s jump in.

10x your lead generation efforts with Wiza Prospect

Focusing on content marketing and SEO for lead generation is a good thing. But if, as a B2B company, you don’t supplement these inbound marketing strategies with outbound lead generation strategies (like cold calling and cold emailing), you’re leaving money on the table, trust me. 

The standard outbound lead gen process begins with defining your target audience or ideal customer profile (ICP) and then building a sales prospecting list. Most B2B companies like to prospect on LinkedIn, but the problem is that many key decision-makers use their LinkedIn profiles for optics; they don’t use the platform much nor do they put their email addresses on there. 

You may need to dig (or guess) a lot to get their accurate contact information. But if you use Wiza, you can save yourself the stress. 

Wiza Prospect, our B2B contact database, gives you access to over 830 million contacts (99% LinkedIn coverage), complete with their accurate contact information, including their full names, business and personal email addresses, mobile numbers, and direct dials. 

You also get advanced filters such as name, job title, job role, skills, and school (for individuals) and name, headquarters location, industry, headcount, and founding year (for companies)—to narrow down the database and find leads that match your ICP. 

Once you’ve found some qualified leads, all you have to do is click Export all leads to export your prospecting list right into your CRM of choice. You can export up to 10,000 leads this way, as opposed to the 2,500 leads that Sales Navigator allows you to export. Once you export your leads, you’ll get a full profile on each one of them, including their names, contact information (email and phone), LinkedIn URL, and 21+ firmographics.

If you’d still like to use LinkedIn Sales Navigator for prospecting but want to be able to find people’s accurate contact information, just download Wiza’s free Chrome extension. After installing it, navigate to Sales Navigator to find your leads. 

After you find them, click on the purple Find email & phone button, and Wiza’s algorithms will scour the internet to provide the individual’s accurate email address and phone number.

You’ll find this information in the popup box on the right side of your screen, along with an overview of the person’s company (including the company’s name, a brief description, industry, headcount, and founding year).
