Whether you’re in SaaS, healthcare, real estate, or any other industry, there’s a way for you to optimize your lead generation strategy. 

A lead gen firm or service can maximize the value of your time by delegating the task to professional solutions while you focus on your core business.

Here are ten great options for doing just that:

(Note: It’s important to do your own research before choosing a company, agency, or service. Consider features, services, pricing, and online ratings and reviews before choosing. We’ve summarized all of those relevant points below.)

1. Belkins

With seven years in the game, Belkins has helped hundreds of small businesses find qualified leads, book appointments, and close sales.

When it comes to pricing, Belkins doesn’t work at fixed rates, so you’ll have to request a quote to get a more accurate estimate for your business.

2. Callbox

Callbox is another marketing agency to consider if you’re looking for lead generation outsourcing.

While the name may imply a focus on cold calling, Callbox offers an array of services including email outreach, telemarketing, and social media marketing campaigns.

Following current best practices, Callbox sources leads through research, proprietary data, and trusted third-party sources.

The agency doesn’t charge by lead. Instead, you can request a quote to find how much you’d pay based on your business needs and desired marketing strategies.

3. Cleverly

Cleverly is a lead generation agency that specializes in all things LinkedIn. They offer the following services on LinkedIn:

  • Lead generation
  • Paid advertising
  • Content creation and ghostwriting
  • Recruiting

So, if you’d like to reach out to LI users but don’t have time to manage the intricacies of the platform, Cleverly has you covered.

The agency also offers building qualified email lists, writing content for email marketing, and executing outreach, enhancing your overall outreach beyond LinkedIn.

Online Ratings:



Cleverly compartmentalizes its services. For example, you can sign up for LI recruiting, without taking, say, paid advertising as well.

That’s why pricing varies significantly based on the specific services you opt for.

While LI lead generation costs between $397 and $891 per month, LI content service is priced at $997 per month. Email lead generation is charged depending on the quality and meeting readiness of the leads.

Essentially, it’s best to visit the pricing page of each service and calculate the combined cost of the marketing services you want.

4. Cience

Note that Cience isn’t an agency—it’s a demand generation platform. The platform deals with multiple aspects of B2B outreach, such as business data, sales engagements, and analytics, allowing you to take charge of lead generation and sales processes.

But in addition to offering a software platform, Cience also lets you hire their sales development representative (SDR) teams to work alongside you and further improve your inbound and outbound digital marketing. It’s like having in-house representatives at a fraction of the cost.

Online Ratings:



Pricing depends on whether you opt for only the platform or both platform and SDR services, and you can get a quote by contacting their sales reps.

There’s also a free platform plan. While its capabilities are limited, it allows you to explore Cience’s potential.

5. Cognism

How to Choose the Right Lead Gen Solution for Your Business

By this point, your head is likely buzzing with options. 

While the decision is ultimately yours to make, consider these points before deciding to work with a lead generation company and/or service: 

1. Would you prefer to outsource as much of your lead generation and outreach as possible?

If yes, you should probably consult a lead generation agency.

If you don’t mind rolling up your sleeves and executing your lead and marketing strategies yourself, then a platform or a SaaS solution is a better fit.

2. Consider the scope of your needs

Are you a small business looking to make local connections, or an eCommerce store targeting a wider audience? Is your focus on cold emailing or generating LinkedIn leads?

Answering these questions will guide you towards providers that specialize in your desired areas.

3. Don’t forget about CRM integrations

The new workflows ideally should play along nicely with all the tools you’re already using. 

If a new tool or the tools a company uses doesn’t mesh well with your CRM, that may be a deal-breaker (need to have a way of tracking their results and progress easily). 

Wrapping It Up

SEO and content marketing can only get you so far in terms of building brand awareness. 

With the right lead generation firm or service behind you, you’re ensuring that you can generate enough leads to keep your sales team busy no matter what stage you’re at in building out your content. 

We hope that this list has helped you explore available solutions and pinpoint the ones that match your criteria. See you in your next customer’s inbox!

Frequently Asked Questions

How much do they charge?

Every lead generation company and service is different, with prices ranging from under a hundred dollars per month for simple services to thousands of dollars for full-service solutions. It all depends on the scope of your project and your overall needs. 

How much should you pay for lead generation?

How much you should pay for lead generation is subjective, based on company size, lead generation needs, and how comfortable you are investing in an external team for generating leads. 

Important questions to ask when considering pricing are: 

  • Will the amount we’re investing pay for itself (any good lead generation service should)
  • Can we easily track their progress and lead generation? This is key for deciding whether to continue investing after months 1, 2, 3 and so on. 

What is the best lead generator?

There is no one best lead generator across every industry and company. However, these methods tend to work well for most B2B services businesses:

  • Email marketing
  • Webinars
  • SEO

It depends partly on where your audience hangs out and what they like to do online, so keep that in mind before deciding where to invest your efforts. 

Are lead generation companies worth it?

A great lead generation company can be more than worth the price. When you hire a lead gen company, you hire experts in their niche who have tailored a service specific to what they’re great at.

Not every lead generation company or service is reputable, however. It’s important to vet who you’re considering working with by looking at online reviews, case studies and content, and reviewing differences in offerings before making a decision.
