10 Lead Generation Companies & Services [+How to Choose]

Let me guess—

You’re running a company and it’s been doing great thanks to referrals and loyal customers. But your goal is to scale your business. And this requires exploring new ways to generate more leads.

Am I right?

If so, you need to build a sustainable pipeline. Your options are either building an in-house sales team to attract potential customers or outsourcing it to B2B lead generation companies.

The lead generation solution market is booming so there’s no shortage of services. The only problem is finding the right one among all the others.

What are lead generation companies?

Lead generation companies collect consumer and B2B data and sell it to businesses looking to buy new leads. They use different methods to segment and categorize the data to make sure the buyers get relevant contacts.  

B2B lead generation companies and software solutions get their leads from various sources through a combination of AI-enabled research and dedicated sales development reps. The best companies aim to deliver qualified sales leads.

Some large lead generation companies offer comprehensive services, such as:

Look for a company that can tailor its services to your needs or specializes in your niche. 

How much do they charge for their services?

Some lead gen agencies charge clients a monthly subscription fee for using their services or software, while others charge per lead. The price per lead depends on the lead’s ‘warmth. Their cost varies depending on the industry, too. Healthcare and insurance leads are thought to be the most expensive. 

Cold leads may be as cheap as $0.15, while hot leads can cost up to $100. Like most things in life, you get what you paid for. So if you go for the cheapest options, you won’t see much return on your investment.  

There are two more, less obvious factors influencing lead companies’ prices—

Some lead list companies sent out contacts to multiple parties which “dilutes” their value. On other occasions, you will only get a fraction of leads in your total TAM. That’s when your chosen leads agency offers exclusive lists of targeted leads and serves other businesses in your niche.

So, are lead gen companies worth it?

Lead gen companies are worth it when you receive qualified or targeted lead generation data with a real potential to convert. Look for lead gen companies that offer at least prequalifying services to ensure sales data’s high quality.

Tip! Before you sign up with any of the lead gen companies, check out the best strategies to generate leads.

How to choose a good lead generation company

Whether you’re searching for lead generation companies for small businesses or enterprises, you need to consider the same finer details. The checklist below will help you evaluate lead services and make sure you’re getting the best deal.

The best B2B lead generation companies won’t mind discussing them.

1. Data compliance

Obtaining accurate sales data should be our number one priority when you use lead generation companies. Otherwise, you’ll be wasting valuable time and resources trying to connect with people who are not interested in your product or service. You won’t be able to fill in the sales pipeline with irrelevant leads and hit revenue goals. 

Tip! Check out the video below that answers all your questions about B2B lead generation companies providing data. 

2. Data source

Make sure the lead generation agency you hire sources leads in a compliant way. The likelihood of lead conversion is higher if leads agree to provide their contact details. You can ask the agency where their leads come from and how often their contact database is refreshed. Outdated information might not be correct even if it was provided voluntarily. 

3. Data relevancy

Make sure that the data provided by the lead gen companies is usable. The obtained data has to serve your purpose (or purposes) which means it has to be easily manipulated. For example, does the company provide filtering and segmentation options for the data? If not, you won’t be able to reach your ideal customers. 

4. CRM integrations

Check if your lead generation vendor can bridge the gap with your sales and marketing teams by providing smooth integration with your company’s CRM. It helps you monitor transfer, and manage generated data. 

5. Sales triggers tracking

Does the company you’re considering analyze sales triggers to increase the chances of conversion? The top B2B lead generation services analyze prospects' activity and performance, like hiring new executives or receiving funding to find new business opportunities for you.

Tip! Find out what sales triggers are and how they can improve lead conversion rates.

6. Data coverage

Double-check if the lead gen companies you're considering can deliver leads globally. Even if you’re focusing your sales strategy on one location at the moment, it can change in time. Make sure that the company you choose can scale as you grow.

7. Local regulations compliance 

Fines for breaching data compliance laws or not taking proper care of contacts’ information can be hefty. So make sure the online lead generation company is registered with international and national regulators and addresses consent requirements.

Tip! Find how to generate leads in a compliant way using B2B data.

8. Services' flexibility

Most lead-generating companies offer a broad scope of services, from website development, to lead nurturing and scheduling appointments. Check with the company if they can tailor the offer to your go-to-market strategy. It’s best to book a meeting with the SDR team to discuss your needs.

9. Pricing

Once a company provides you with a personalized solution, make sure the pricing is adjusted accordingly. Check if it is competitive and provides real value. For example, some online lead generation services resell lead lists to different clients or ask you to pay for invalid leads. 

Tip! Learn more about the cost of lead generation and how to calculate cost per lead. Make sure you’re not overpaying for leads and check which campaigns are most cost-effective.

10. The ownership of generated leads

Some B2B lead gen companies only rent their contact databases to you. It means you lose access to leads after the rental period. So if you’re thinking about building a sustainable sales pipeline in the long term, choose a solution without an expiration date. 

11. Support for in-house teams

Finally, evaluate your in-house resources. If you already have a sales team, consider how you can use a lead generation firm to support their work. Sometimes all you need to do is to provide the right sales intelligence. So they can better optimize the revenue operations process and have time to nurture active leads.
