# 6 Best B2B Lead Generation Companies to Fill Your Pipeline

5 min read time 

![6 Best B2B Lead Generation Companies to Fill Your Pipeline](https://www.leanlabs.com/hs-fs/hubfs/lean-labs-growth-marketing-A052-purple.png?width=765&height=430&name=lean-labs-growth-marketing-A052-purple.png) 

According to HubSpot, [sixty-one percent of marketers](https://www.hubspot.com/state-of-marketing) say lead generation is their number one challenge.

Unfortunately, this leads to a lead quality issue. Sixty-one percent of B2B marketers send all their leads to sales, but [only 27% are qualified](https://marketinginsidergroup.com/content-marketing/50-must-know-statistics-improve-lead-generation-strategy/). That's why it's essential to focus on lead quality over quantity.

Quality leads have shorter sales cycles and become better long-term customers.

And if you don't feel your in-house [lead generation](https://www.lean-labs.com/blog/lead-generation-through-content-marketing-guide) is bearing enough fruit, you may want to outsource the process to an expert.

This article is for you! We'll show you what you should look out for when [hiring a lead generation company](https://www.lean-labs.com/solutions), what the best options are so you can focus on driving growth in your business, and work with a partner that shares your goal.

They might fill out a form, sign up for a free trial, or download a lead magnet.

Lead generation is the process of attracting people to your business and increasing their interest through nurturing. You want to warm up potential customers.

The process of lead generation is pretty simple and should be intuitive:

1. A person discovers your business through researching their problem or query on Google and finding your blog, website, or social media content.
2. They consume your content and click on a [call-to-action](https://www.lean-labs.com/blog/develop-a-perfect-cta-for-your-website) (CTA) button or image that encourages them to take action.
3. They click through to a landing page, and you capture their lead information in exchange for an offer.

There are other ways to capture leads, too. But remember, you're looking for qualified leads, not just a high quantity.

### What Do Lead Generation Companies Do?  
  
The primary function of a lead generation company is to deliver warm and [qualified leads](https://www.lean-labs.com/blog/qualifying-leads-how-to-identify-score-qualified-leads) directly to your business. They can target your ideal customers with personalized campaigns and ensure that you get sales-qualified leads.

Lead generation companies then sell you the leads they gather. It's best practice to partner with a lead generation company if you want genuinely qualified leads, but you can also buy a list. 

However, this is risky, and you won't know how accurate the data is or if those leads are qualified. Also, once you stop paying for leads, you stop getting leads.  
  
###   
What Should You Look Out for When Hiring a B2B Lead Generation Company?  
  
Before you work with a lead generation company, ask the following questions:

* Are they [data-driven](https://www.lean-labs.com/blog/data-driven-growth-marketing)?
* Do they work with you?
* Where do they source their leads from?
* What is their lead generation process?
* Who are their existing and past clients?
* How do they qualify leads?

Any company worth its salt will have answers to these questions, and if they don't? Steer clear.

### B2B Lead Generation Companies: Which One is Right For You?  
  
As always, depending on the size of your business and your goals, you can find a [lead generation](https://www.lean-labs.com/blog/demand-generation-vs-lead-generation) company to fulfill your needs.

Just remember, the quality of leads is far more critical than quantity. Do you want the best [ROI for your marketing](https://www.lean-labs.com/blog/drive-content-marketing-roi) efforts? Of course, you do. So you need to pass qualified leads to your sales teams to make their jobs easier.

It's best to work with a company that will partner with you. Outsourcing lead generation and forgetting about it is a mistake. Can anyone else honestly know your customers? And if they do, without constant communication, how will they know if any changes occur?

Lead generation is only part of the process. What happens once you've acquired leads is more important. It's best to [work with a growth team](https://www.lean-labs.com/blog/growth-team-101) that's invested in your revenue growth. 

For example, at Lean Labs, we focus on Tech and SaaS brands and use a "[value over profit](https://www.lean-labs.com/growthteam)" model, meaning that if the leads we generate don't reliably ascend to customers and drive business growth, we don't profit.

Lead generation is the process of attracting people to your business and increasing their interest through nurturing. You want to warm up potential customers. The process of lead generation is pretty simple and should be intuitive A person discovers your business through researching their problem or query on Google and finding your blog, website, or social media content. They consume your content and click on a call-to-action (CTA) button or image that encourages them to take action. They click through to a landing page, and you capture their lead information in exchange for an offer. There are other ways to capture leads, too. But remember, you're looking for qualified leads, not just a high quantity.  What Do Lead Generation Companies Do? The primary function of a lead generation company is to deliver warm and qualified leads directly to your business. They can target your ideal customers with personalized campaigns and ensure that you get sales-qualified leads. Lead generation companies then sell you the leads they gather. It's best practice to partner with a lead generation company if you want genuinely qualified leads, but you can also buy a list. However, this is risky, and you won't know how accurate the data is or if those leads are qualified. Also, once you stop paying for leads, you stop getting leads. What Should You Look Out for When Hiring a B2B Lead Generation Company? Before you work with a lead generation company, ask the following questions Are they data-driven? Do they work with you? Where do they source their leads from? What is their lead generation process? Who are their existing and past clients? How do they qualify leads? Any company worth its salt will have answers to these questions, and if they don't? Steer clear.  6 Best B2B Lead Generation Companies Belkins - best for outbound appointment setting Callbox - best for global enterprise businesses Operatix - best for mid-market businesses WebFX - best for SEO and PPC Cleverly- best for LinkedIn lead generation Lean Labs - best for organic growth #1.

As always, depending on the size of your business and your goals, you can find a lead generation company to fulfill your needs. Just remember, the quality of leads is far more critical than quantity. Do you want the best ROI for your marketing efforts? Of course, you do. So you need to pass qualified leads to your sales teams to make their jobs easier. It's best to work with a company that will partner with you. Outsourcing lead generation and forgetting about it is a mistake. Can anyone else honestly know your customers? And if they do, without constant communication, how will they know if any changes occur? Lead generation is only part of the process. What happens once you've acquired leads is more important. It's best to work with a growth team that's invested in your revenue growth. For example, at Lean Labs, we focus on Tech and SaaS brands and use a value over profit model, meaning that if the leads we generate don't reliably ascend to customers and drive business growth, we don't profit. If you want to know what we would do if we were your growth team, check out our free resource, the Growth Playbook. This is our most valuable training, as it lays out the exact steps for how to plan, budget for, and accelerate growth. ",
