Top 25 Lead Generation Companies of 2021

Published by Yash Chawlani on

High-quality leads are the driving force behind every successful business. Even if you build the most revolutionary products, they won’t yield revenue unless you identify, nurture, and convert the right leads.


According to a HubSpot report, lead generation is the topmost priority for modern marketers. But, 60% of marketers report that their customer acquisition cost (CAC) has increased over the last three years.


Here’s the thing – marketers and sales reps shouldn’t be spending most of their time finding and tracking leads. Instead, they should utilize their time to optimize the RevOps process, nurture active leads, and develop new conversion strategies.


This, in turn, emphasizes the need to empower marketing and sales teams with the right lead generation services and tools.


Now, you’ll find a plethora of lead generation companies and platforms on the internet. But knowing which agency or software is the right fit for your business is crucial.


In this blog, I’ve handpicked the top lead generation companies and solutions you should work with. But before getting started, I’ll walk you through the difference between lead generation companies and software solutions.


Lead Generation Software, Services, and Agencies – What You Need to Know

Are you looking to outsource all tasks related to lead generation, including lead qualification and appointment scheduling? Then a lead generation agency would be the right fit.


Lead generation companies leverage various techniques, including content marketing, telemarketing, pay-per-click (PPC) advertising, and email marketing.


Lead generation companies offer a wide array of services, such as:

  • Sales research
  • Lead engagement
  • Account-based management
  • Appointment setting
  • CRM migration


On the other hand, a lead generation software automates various steps in the process of identifying and nurturing qualified leads.


Think of it as an all-in-one platform that helps you find, nurture, and convert leads using various strategies. It takes some of the load off your marketers’ and sales reps’ shoulders and boosts their productivity.


What should you choose? Do you need both lead generation software and agencies?

The choice between a lead generation agency and software depends on what your business needs. And, more often than not, a software is something that you will always need to automate repetitive operations.


If you’ve got a team of skilled sales reps and managers, you could consider providing them with suitable tools. It’ll help automate routine tasks, such as lead identification and follow-up. This, in turn, will give your sales team more time to forge lasting customer relationships, reduce churn, and boost customer retention.


But if you have a small team and want to outsource lead generation activities or need help getting initial traction, lead generation companies can help.


If you choose a lead generation agency, you might also need a lead generation software and have both work for you. Talk to your team members and carefully assess their needs before making the decision between a lead generation agency and software.
