11 Best Lead Generation Companies in the US

11 Best Lead Generation Companies in the US

Hiring a lead generation company that grows the sales pipeline of your business in the United States often comes with different problems. Although most of these companies promise great results, they tend not to deliver them. 

Instead, they bind you into some contracts – a minimum of 3 months — and charge you for their lead generation processes which don’t guarantee any ROI for your business. To avoid this, we have curated a list of the top lead generation companies in the United States. 

We’ve also reviewed each company to help you understand what to expect from them. So, let’s get started.

11 Best Lead Generation Companies in The US 

Here is a quick detail of the top companies in the United States that you can consider for your lead generation and appointment setting service needs. 

1. Nerdy Joe

Yes, that’s us. 

You might not be surprised that we made the top of our own list for the top US-based lead generation companies. But without an ounce of bias, we will detail why we are the best company you need to hire for your lead generation needs in the US. 

Unlike most lead generation agencies, Nerdy Joe is a B2B digital marketing agency that only offers email marketing and outbound lead generation services (i.e., cold emailing). We like the idea of offering only one service and performing it excellently. 

Our team of experienced lead generation and appointment setting service specialists uses proven strategies to attract and engage potential customers through cold outreach strategies such as cold email and email marketing. 

We work closely with our clients to understand their unique needs and tailor our services to deliver the results they’re looking for. We believe that generating leads is only half the battle — the real challenge lies in converting those leads into loyal customers for you. 

That’s why we focus on generating leads that are not only interested in your product or service but are also more likely to make a purchase. 

Working with us is pretty straightforward as we don’t require you to commit to a certain number of months, and you know exactly what you get when you choose to work with us.

Why Nerdy Joe is the best lead generation service provider in the US for you

You get a company that focuses on delivering actual results, rather than just boasting about the quantity of emails they send out or how many channels they use.

So, there are four types of lead generation companies out there. 

  • The first type charges you based on how many emails they send or how many contacts they add to your list. 
  • The second type charges you a monthly fee, but they don’t always deliver on their promise to get you the best leads. 
  • The third type considers anyone who downloads an ebook or PDF to be a “lead” and charges you for that. 
  • And finally, the fourth type charges you based on the number of qualified leads they bring in for your sales team.

But let’s be real, only the last type of company truly cares about your return on investment (ROI) and gets you the best results. 

If you’re looking for a lead generation service provider’s help, it’s because you’re not growing as quickly as you want to and you need more leads to sell to. That’s it.

That’s why we don’t care about or bother you with things like the number of emails we send or the work we do — we’re all about the results we get for you. 

Our team service is all about providing value and focusing on the metrics that matter, like the number of positive replies we get, the number of meetings we book, and the lead-to-close rate.

For example, if you want to work with us to increase your SaaS product’s customer base, we’ll report back on: 

  • the number of new sign-ups you get, 
  • the number of positive replies you get, 
  • the number of demo calls we book for you, 
  • and the number of new clients we bring in for you. 

If you’re selling a CBD-based healthcare solution to individuals with chronic pain, we will reach out to healthcare centers and doctors who treat people with conditions like arthritis, multiple sclerosis, fibromyalgia, etc., and we report back on:

  • the number of doctors wanting to buy
  • the number of doctors wanting to learn more by hearing from you
  • the number of doctors wanting to describe their clients’ unique conditions
  • Etc.

You get the point, yeah?

Our offering is tailored to your specific goals and what outcome matters most to you. 

You get a company that truly reflects who you are and what you stand for — rather than one that just sends out generic, impersonal emails to everyone.

If you had to pick between two companies that generate leads for you, which one would you choose? 

  • A: The first company creates a massive list of thousands of people and sends them all the same generic emails. 
  • B: The second company creates a targeted list of 30 prospects and writes personalized, relevant, and convincing emails to send to them.

I’m guessing you’d prefer company B, right?

Sadly, the lead generation game has gone through some major changes in recent years. You only need to check out Twitter to see what most self-proclaimed lead generation gurus are preaching these days.

Many folks out there in the lead generation industry think that in order to have success with cold outreach or lead generation, you have to send around 1000 emails per day. 

Even some of the most notorious lead generation agencies out there swear by strategies like building hand curated lists of 30000 people and reaching out to them all in a single month. 

They believe that by sending out massive amounts of emails, they’ll eventually convert a significant percentage of the recipients into leads for their clients. 

And while this might seem like a good strategy from a mathematical point of view, it’s actually not the best way to go about things. 

From our experience, here is what it could mean if you are targeting huge lists: 

  • Lead blasting: If you are sending emails to this many people, it means that you are not taking the time to properly research your prospects to tailor your email to each individual. You’re blasting people with generic cold emails and pushing for action. They might say you’re selfish and lazy. 
  • Poor leads quality: Since there is no super personalization, the quality of the leads you get the meetings with will be subpar, and you can’t convert, at least not easily or in a short timeframe. 
  • Pissed prospects: Some prospects can be mean to you, saying things like “Remove me from your list”, “Don’t ever email me again”, or worse, “Your cold email sucks”. 
  • Your brand reputation is on the hook: Targeting people with generic emails can negatively impact your company’s reputation. This can be particularly damaging if you are in a competitive industry or rely heavily on word-of-mouth referrals. Also, we are sure that’s not how you want your business to be represented.

That’s why we take a different approach at Nerdy Joe. Quality outreach requires a lot of work and time, and targeting huge lists doesn’t help with that, and we understand it. 

So, instead, our approach is all about targeting a specific audience and crafting personalized messages for each recipient. 

Our ideal scenario is that we send 20 emails, get 15 replies, 10 positives, and get you 4 sales-qualified leads, meetings or sign-ups.

We achieve this by being super-specific in who we target and creating personalized messages to very short prospect lists, and guess what? It works. 

We spend time learning and researching your ideal customer profile (ICP) in and out before we send a single email. 

We want each recipient to feel like you know them personally and take you seriously. Even if they don’t sign up for our offer, we still want them to give you a pleasant response. 

It requires researching each prospect individually and collecting data points to create cold emails that stand out and make them love what you have to say or offer them.

Just for some context on how this works for us, here’s an example of a reply we received as we reached out to a VP of Marketing who has historically blocked or reported SPAM to anyone who’s sent him a cold email.

Here’s another example where we pitched a Head of Marketing, and here’s the response. 

Gurus might say otherwise, but we usually focus our outbound lead generation campaigns on a small group of 10 to 15 people, not a huge list of 1000 prospects. We believe that the best way to make sales is by building trust and relationships.

You might be wondering how we gather information about each person in your target audience to personalize our approach. Well, we do a lot of things. We: 

  • listen to podcasts your potential customers have appeared on, 
  • read blog posts they’ve written, 
  • keep an eye on their social media posts on platforms like LinkedIn, Twitter, and Mastodon. 
  • check out discussions they’re involved in on online forums.

All this data helps us come up with unique and personalized ways to start an email conversation with your prospects. It helps us write cold emails that naturally stand out and connect with your target audience at a core level. 

Here’s an example of how it works in real life: we reached out to Ben Sailer, the Head of Content at CoSchedule, and asked him if we could write for them.

Here’s what he replied 1 hour later.

Here is another successful example from a similar strategy.

The emails we sent to those potential clients were so darn compelling that they just had to take notice and even offered to bring us on board.  

You get a team of experts with an unwavering commitment to data quality: we do the prospecting, list building, and everything manually.

At our company, we’ve made it a policy to never use our clients’ data for lead generation campaigns. As well, unlike most lead generation companies, we do not rely on data intelligence tools such as ZoomInfo or Lusha for data.

We don’t trust these data sources because they only aggregate technographic and demographic data. For example, using these tools, it’s easy to find data regarding companies that: 

  • Are in the accounting software industry, 
  • Have 30 to 65 employees,
  • Are series B-funded companies,
  • Are in Europe,
  • Use Slack or Digital Ocean as part of their tech stack.
  • Have a ping pong table at the office. 

The problem with this data is that it can only serve to craft obvious cold email opening lines like:

Subject line: Freshworks integration

Hey [[First name]],

You are in the UK and use Freshworks. Let’s hop on a call.

So, we like to take it a little further down the personalization road. We seek and make use of psychographic data and other types of data.

How do we do that?

When we sign a new client, one of the first things we do is ask about their ICP.

We ask questions like:

  • Which type of clients have the highest lifetime value?
  • Which type of clients is easiest to close?
  • Which type of clients churns the fastest?
  • What are the top 3 objections you hear from prospective clients during sales calls?
  • Why did you start your company? 
  • What pain points were you trying to solve?
  • Etc.

By answering these questions, we can pinpoint precisely who we should target and why. And this type of information makes the difference between: 

“We’re targeting series A tech companies,” 


Our ICP is a VP of Sales at a b2b software company selling to HR professionals, and his main pain points are lack of organization, time management, and team collaboration. He often refers to XYZ podcasts to get insights as to how to manage his team efficiently.” 

Once we have a clear understanding of who the ICP is, we proceed to manually build our list, and that’s what we use to run our lead generation campaigns.

You don’t have to sign any contract with us — if you’re happy with our service, you can renew your subscription, and if not, you’re free to stop it anytime.

Most lead generation companies require you to sign a contract that lasts for 3 to 6 months, but not Nerdy Joe. 

We’re a subscription-based business that offers results right from Month 1. You can renew your subscription based on your satisfaction with our service and your budget. Plus, we won’t waste your time with unnecessary meetings or send you vague proposals based on limited information about your company.

Here is why you should dig our subscription system:

  • Unlike retainer contracts, our system doesn’t force you to commit to a fixed period of time and payment.
  • It offers less risk than a retainer contract. You won’t have to worry about the financial and legal implications of breaking a contract if you’re not satisfied with the service.
  • A retainer contract may cause a service provider to become complacent since you’re already committed to paying for their service, regardless of how satisfied you are. The system keeps us on our toes, and we know we have to deliver, and that’s what we do.
Your chosen plan clearly spells out what you’ll receive

Our offerings and pricing are clear — and this is probably why we’re one of the best lead generation agencies. You choose a plan based on your budget and needs, and you know exactly what you get at the end of the month.

  • No, “it depends on a lot of factors.”
  • No, “Your account manager swallowed the key to his office and couldn’t work.”

If you have product-market fit and are solving a problem that most people have, it is almost everything we need to get you results. But if you’re still figuring out who your solution is best for, then we’re probably not going to be of help.


Our lead generation service’s pricing is crystal clear. We’re three plans:

  • Silver: It costs $499/month and only gives you 2 hot LEADS.
  • Gold: This is the plan we recommend, as it gives you the biggest bang for your buck. It costs $999/month and gives you 6 hot and sales-qualified appointments or LEADS.
  • Platinum: This plan is for mid-level to enterprise companies willing to fuel their sales team with up to 15 sales-ready leads on a monthly basis.

Our email marketing pricing includes the following:

  • The tech stack we use to build your prospect list and send and monitor your campaign.
  • A complete list of prospects that fit your buyer persona and ICP.
  • The campaign setup fees.
  • A dedicated management team.
